Renovation:Moriggia Pelascini Hospital, Gravedona

Higher effi ciency, lower energy costs – thanks to state-of-the art condensing boiler technology

The “Ospedale Moriggia Pelascini”, with 210 beds,is situated in the picturesque, tranquil location of Gravedona, on the northern bank of the Comer Lake, in the Lombardy region. The hospital’s entire heating system was ageing and too costly to run. Consequently, the planning of a new heating sys -tem was essential.

The brief was to replace the old boilers with new, modern ones. The decisive factors for the planned renovation were fi rstly the improvement of the system’s cost-effi ciency in order to reduce costs, and secondly to signifi cantly reduce of the emis -sions in order to meet the requirements of the local legal regulations. ELCO had the solution ready on hand - namely, the gas condensing boilers RENDAMAX 3605, which tick all the boxes in terms of cost-effi ciency and emission values.

Renovation: Manhattan Center –Sheraton Hotel & Thon Hotel, Brussels

First-class hotels –fi rst-class heating system

In the Manhattan Center, Brussels’ modern busi-ness complex, lies the Sheraton Hotel and the Thon Hotel – two of the city’s most exquisite hotels. In order to accommodate business travellers and tourists in style, a new conference centre has been built and the spacious rooms have been en hanced. In the scope of the renovation work, the joint heating system of the two hotels was also brought up to date. Two modern R600 gas condensing boilers will immediately replace the old standard gas burners.

ELCO has already successfully collaborated with the Manhattan Center Sheraton for several years. ELCO also convinced its customers for this order with exceptional service from the signing of the contract to the maintenance. The heating system was renovated without interrupting the operation of the hotel thanks to the compact construction and the easy installation of the new heating sys -tem. It combines the highest degree of system

fl exibility with outstanding performance. The result is quality at a fair price and an investment that has quickly paid off.

The benefi ts of the R600 boiler

This new generation of gas condensing boilers has been de veloped especially for greater performance requirements in commerce, industry and municipal housing. With heat ex -changers made from stainless steel and the patented com -bustion engineering, the R600 provides for minimal erosion and a consistently high degree of effi ciency and modulation. At the same time, the normal supply level is 110.4 %, meaning effi cient and environmentally-friendly energy production whilst emitting extremely few pollutants.

The new system

Both hotels combined have more than 1,000 rooms on 30 storeys. This enormous space required an effi cient heating system, which the R600 series by ELCO provides. Up to eight boilers and 15 mixer circuits can be synchronised, thereby generating up to 4,500 kW. Renovation using modern R600 gas condensing boilers enables 35 % energy savings com -pared to the old system. The result is signifi cant cuts in costs, namely up to € 80,000 in seven months. A weather-based electronic control reliably monitors all functions. All settings can be retrieved or changed using a digital display window.

In addition to its safe handling, another benefi t of the R600 gas condensing boiler is its easy assembly. Preassembled system kits for hydraulic separators and plate heat exchangers make it particularly easy to plan and install. This is the Plug & Play principle.

Feel-good heat for exquisite hotel comfort

Both hotels have central locations in the heart of the Belgian

capital. Directly across from the most vital shopping quarter

Rue Neuve, the old town with the Grand Place is only fi ve

minutes by foot. The hotels offer all services and amenities

that one would expect from a fi rst-class establishment. The

experienced and attentive hotel staff tend to their guests at

all hours and ensure maximum comfort. ELCO provides the

adequate heating comfort.

New building:Offi ce complex in Paddington Central, England

Outstanding BREEAM environmental rating thanks to innovative heating technology

Futuristic and ultra-modern. The offi ce complex built according to plans drawn up by Sheppard Robson and Skanska, with around 24,154 m² fl oor space and with the address and name ‘One Kingdom Street’, is the most innovative project in Paddington Central. As one might expect, the building’s planners were also innovative in terms of the heating technology – whose eco-friendliness has been awarded a top rating with the BREEAM classifi cation ‘Excellent‘, with the NOx emission values even undercutting the best BREEAM standard by a signifi cant margin.

Five RENDAMAX 3600 boilers have been in -stalled – with a connection to the high and low-temperature heating circuits. They satisfy all the requirements in terms of effi cient heating output and energy management. Three boilers supply the air conditioning and ventilation systems and the under-fl oor heating for the entire fl oor space, whilst the two smaller boilers supply the hot water and radiator heating systems.

The new system

The fi ve state-of-the-art RENDAMAX 3600 condensing boilers

with gas pre mix burners from stainless steel have a total out-

put of 4.5 MW. They excel with their outstanding thermal out-

put, low consump tion, low sound level and low NOx and CO

values – and what is more in highly compact form. This allows

a great deal of fl oor space to be saved. The RENDAMAX 3400/

RENDAMAX 3600 burners offer a power range of 660 kW

to 1.9 MW. The ability to connect up to 8 boilers in cascade

makes these condensing boilers the perfect solution for large

commercial buildings.

In Paddington Central, the three large RENDAMAX 3605 boilers

supply the air conditioning and ventilation systems, the central

convectors and the warm-air heating of the whole building.

Two smaller boilers ‘manage’ the heating circuits with a fl ow

temperature of 80 °C for the heating and hot-water generation.

Modulating, water-cooled gas premix burners ensure maxi-

mum effi ciency coupled with minimum NOx emission values.

Renovation:Lyon town hall and opera

Two historical buildings benefi tting from the most modern heat comfort

The “Hôtel de Ville“ in Lyon is one of the city’s most important historical monuments. It is found between Place des Terreaux and Place de la Comédie, directly across from the opera. The building has been protected as a historical monument since 1886. The “Opéra Nouvel” houses the National Opera of Lyon. The opera house was originally built in 1831, before well-known French architect Jean Nouvel put signifi -cant time and effort into converting it between 1985 and 1993. As a result, the building was then named after him.

The heating systems of the two buildings were, like in many other communities, technically out -dated and oversized. The result was high exhaust gas temperatures, discomfort and signifi cantly excessive heating costs. ELCO had scored with the city for many years with its reliable customer service. The old system registered virtually no disruptions. This also played a role in the deci-

Very high heat output in compact form, low consumption and low NOx and CO values – these are the characteristics of the RENDAMAX 3500 series gas condensing boilers. The series includes a total of fi ve different sizes, which cover out puts ranging from 613 to 1,000 kW. The model series is also ex-cellent for both renovation and new buildings. Long assembly times are not an issue: RENDAMAX 3500 gas condensing boilers are delivered complete from the plant with a built-in pre-mix boiler and custom-fi tted mountings. All components are pre-set and tested before delivery.

The new system

In order to provide the “Hôtel de Ville” and, as needed, the “Opéra Nouvel” with central heat from a boiler room, two modulating RENDAMAX 3504 gas condensing boilers were connected in a cascade. The advanced boiler management with load control and automatic digital fi ring devices also enabled the system to be connected to the existing building control system. The two buildings are connected by pipe systems underground. When needed, the opera house can also be heated easily and at low cost in addition to the base heating system installed there. The low volume of water and the compact heat exchangers allow for a fast, direct and effi cient transfer of heat. The central digital control offers the most operating and maintenance ease.

The RENDAMAX 3504 had another advantage. It had very close access to the historical building‘s central engineering room. Because the ELCO boilers can be dismantled and reassembled easily and quickly on site, this led to no problems whatsoever.

Custom-made, energy-saving technology

The theatre and later opera house of Lyon was originally built in an Italian style in 1831. It had a horseshoe-shaped hall, which was lined with rows of loges. The new construc-tion still has the same lobby and exterior. Nouvel tripled the area of the building. He achieved this by excavating one of the underground storeys, where the rehearsal rooms were located, and through an attention-grabbing barrel-shaped construction of steel and glass on the roof. This doubled the height of the building and covered the stage area.

New building:Parkstad Limburg Stadion, Kerkrade, Netherlands

The new star of the stadium: The RENDAMAX 3605

The vision for heating the new Parkstad Limburg Stadion in Kerkrade had been clearly defi ned: an effi cient, high-quality heating system in a cascade solution. The standards had been set high. The system is to cover the energy needs for the pitch heating system, the hot water for all showers and the home team Roda JC’s swimming pool as well as the heat for the offi ces and public lounges (air conditioning and radiators).

Those responsible for building the stadium chose three RENDAMAX 3605 gas condensing boilers, which provide overall heating power of around 3,300 kW. Another criterion in their decision was the fact that both the installation company Imtech and ELCO are in the area near to the football stadium. Moreover, the two companies had

established a good collaboration over the years that could be of benefi t.

RENDAMAX – Peak output in the upper range

The RENDAMAX 3400 and 3600 series are ideal for use in larger real estate and commercial properties. Here they cover the upper power range all by themselves – in 11 power ranges from 639 kW to 1,189 kW. The RENDAMAX 3400 series offers an optimal cost-benefi t ratio when high design temperatures are required and a high degree of effi ciency in the case of a very high normal supply level. Additional advantages include the compact dimensions, the particularly quiet operation and the extremely low emissions.

The new system

The installation of the heating system was planned under the roof. For this reason its weight took on particular signifi cance. The RENDAMAX 3605 was very convincing given the fact that it was designed for very little water content (only 117 litres for 1,097 kW), thus making it substantially lighter than comparable burners. The advantage resulting from this is that the roof construction did not need to be additionally strengthened.

The ratio between the heat output and the size of the gas con-densing boiler has allowed for a relatively compact central heating room. This has enabled more space for air condition-ing and other technical systems. The option of operating the RENDAMAX 3605 gas condensing boiler with low gas pressure (min. 25 mbar) reduced the size of the gas booster for the central heating room. The overall capacity of the boilers is roughly 3,300 kW.

Home game for RENDAMAX: With maximum power and the highest degree of effi ciency

The Dutch football club Roda JC (Sport Vereniging Roda Juliana Combinatie Kerkrade), whose fi rst team plays in the top football league in the Netherlands, has played its home games at the Parkstad Limburg Stadion since August 2000. The stadium, located in the Kerkrade community, was built between 1999 and 2000 and can fi t up to 20,000 spectators. Roda JC inaugurated the stadium on 15 August 2000 in a friendly match against Real Zaragoza from Spain.

Services to match the heating system

Modern heating systems are packed with sophisticated techno-

logy and complex electronics. Particularly in commercial and

public buildings, it is essential to have a system with a full ser -

vice history. The failure of the heating system can have dire con -

sequences in these buildings, resulting in production losses, rent

cuts and action for damages. Schools and hospitals also need to

be able to rely on trouble-free operation. For this reason, ELCO

offers the right services to match each heating system and every

requirement. From the professional commissioning, to the routine

maintenance through to servicing and reliability checks over

many years. Assure yourself long-term functional reliability and

cost certainty with an ELCO service agreement.

The new system

The RENDAMAX 3604 gas condensing boiler produces a highly

effi cient output per ground area of around 380 kW/m² and an

output-to-weight ratio of 0.98 kW/kg. This is approx. 14 kW per m²

greater output than a comparable boiler that also almost weighs

twice as much, with far bigger dimensions. The mo dulating, water-

cooled premix burner ensures maximum com bustion effi ciency –

and what is more with extremely low NOx emission values of just

11.5 mg/kWh, i.e. signifi cantly below the BREEAM standard.

The heat exchangers, fully equipped with stainless steel com po -

nents, increase the durability and service life of the RENDAMAX

3400/RENDAMAX 3600 SB series. The modulating premix burners

with innovative water cooling excel with their precision controll-

ability coupled with high effi ciency and clean combustion

processes. Thanks to rated output ranges of 660 kW to 1.9 MW

and the option of connecting up to 8 boilers in cascade, the

RENDAMAX 3400/RENDAMAX 3600 SB gas condensing boilers

are ideal for use in commercial buil dings, such as offi ce blocks,

schools, shopping centres, hotels, residential buildings and

district heating plants.

Modernisation: “Das Zunfthaus zur Zimmerleuten“, Zurich

ELCO ensures pleasant heating and an outstanding energy balance

”Das Zunfthaus zur Zimmerleuten“, in Zurich has been freshly renovated and reopened in October 2010. A fi re back in 2007 gutted a large part of the building on the fi rst fl oor along with the party hall. The water used for extinguishing the fi re also however left noticeable traces, particularly in the rooms beneath this historic building, where the gas heating system was also affected, leaving it badly damaged and having to be replaced.

The newly restored splendour of the building also includes a high degree of comfort. This is ensured by a new, modern heating system from ELCO. Two wall-mounted R30 gas condensing boilers (each with 85 kW output) have been installed. This heat-ing system is very fuel-effi cient and excels with its low energy consumption and low pollutant emissions. As such, for the entire installations, it is possible to save up to 25 % energy compared with the old system.

The new system

The new technology for the time-honoured building came from

ELCO – namely, two R30 gas condensing boilers, connected in

cascade. The total thermal output of the two boilers is 170 kW

(2 x 85 kW). Thanks to the automatic adjustment of the burner

out put (modulation 1:12), combined with a weather-controlled

regulator, precisely the right amount of heat is always gene-

rated as and when required – this saves energy and reduces

emissions. The system supplies water heaters, air heaters, under-

fl oor heating and radiator heating systems.

For the planning and execution of the entire installations, only

those components could be considered that took up little space.

This was because in the only available utility room the space

available was extremely restricted – every centimetre counted.

The wall-mounted R30 from ELCO provided the perfect solu -

tion for this requirement. After all, compared with fl oor-mounted

boilers, this model makes it possible to save a few square metres

of valuable fl oor space.

Outstanding performance in the tightest of spaces – the ELCO system saves space and energy

„Das Zunfthaus zur Zimmerleuten“, originally called “Haus

zum Roten Adler“, is one of Zurich’s most important historic

buildings. It was built in its present form around 1708. The

oldest part of the building, a keep, dates back even as far as

the year 1156. The house is the headquarters of the “Zunft

zur Zimmerleuten”, but is also open to the public. “Das Zunft-

haus zur Zimmerleuten“ has a bar, a restaurant with terraces,

a conference centre and beautiful guild rooms. It is located

in one of the nicest areas of the city, directly on Lake Zurich.

Renovation: Lindner Congress Hotel, Düsseldorf

Economical cosiness for a luxury hotel

Innovative hotel concepts and a wide variety of relaxation facilities are the hallmark of the high-class hotels and resorts of the Lindner Hotel Group. One of their top establishments is the Lindner Congress Hotel, Düsseldorf. Excessive energy costs and warmth that no longer met modern requirements on comfort made it neces-sary to renovate the heating system. Two ELCO modulating gas condensing boilers formed the heart of the new system. The result was fl exible, comfortable heating and warm water that met all requirements – with the highest reliability and at calculable cost. The renovation was carried out parallel to the daily running of the hotel.

The starting point

The old heating no longer met the requirementsA standard boiler with a jet burner and return riser and a power of 1 Gcal served to cover the base load. A second boiler of the same type covered the peak loads. Heating and warm water processing were distributed over 3 equipment rooms.

Hotel Lindner had rigorous requirements on warm water and heating comfort The energy costs made up too large a portion of the over-all operating costs of the hotel. The convenience of the heating and warm water did not meet the requirements. Hotel Lindner therefore decided on a new, modern heating solution. The greatest challenge was that the renovation was to be carried out parallel to the daily running of the hotel.

• Hotel with 230 rooms, 10,500 m² heated area • Energy consumption: 3,900 MWh

The new system

Cascaded gas condensing boilersTwo RENDAMAX 3603 gas condensing boilers are arranged in a cascade. This gives a total power of 1,692 kW, which is adjusted by mo dulation. The condensing boilers are of split HT/LT construction. This makes it possible for some 75 % of the annual heating operation to be kept within the condensing range. The heating solution achieves a standard effi ciency factor of 106/109.8 %.

The new heating system further reduces the temperature of the waste gases to below 80 degrees. Stand-by losses are reduced by the gradually raised boiler temperature. The central heating and the warm-water processing are located in 2 equip ment rooms. The harmonised, modular construction simplifi es installation. It was possible to maintain the daily running of the hotel.

The services to match the system:

COMFORT Service for fl exible coverage With the COMFORT Service, the new heating system is always optimally maintained. Fault-free operation is assured year after year.

• Cost transparency The COMFORT maintenance package protects the Hotel Lindner for at least 1 year from increasing maintenance costs. At the end of each year, the contract is automatically renewed for a further year. Signing the contract at commissioning pro-longs the guarantee period to 5 years, including original ELCO replacement and wear parts.

• Protection of investment System commissioning and the annual maintenance keep the entire system in perfect condition at all times.

• ReliabilityThe COMFORT Service offers everything necessary for re-liable operation, from the annual maintenance with defect removal free of charge (24 hours a day, 365 days a year) to the main inspection.

Remote monitoring minimises the risk of failure The existing remote monitoring system was taken over by ELCO. This permits remote diagnosis at any time and from anywhere, even before the operator of the heating notices anything. The risk of damage through failure of the heating is thus minimised.

Energy-saving contracting for a clinic

Highly reliable planning for an energy-saving heating solution

The building under restoration is a large clinic with a long tradition. Renovation of the heating system was due, in order to save energy and increase convenience. The investor and heating contractor, Cofely, decided on a partnership with ELCO. Cofely is Europe’s leading name in the effi cient use of en ergies. The aim of this specialist company is not only to use energies as economically as possible in buildings, but also to make the cooperation with its partners as effi cient as possible. The team effort with ELCO thus produced a tailor-made heating solution.

Thanks to energetic renovation measures, it waspossible to achieve energy savings of 20 %. Partof the optimal heating solution is the perfect service. Cofely decided on the 10-year all-inclusive package from ELCO, and thus for reliable operation and transparent costs.

The starting-point

Obsolete equipment, excessive energy consumption Originally there were three 4,000 kW high-pressure warm- water boilers with a fl ow temperature of 150° C installed in the hospital. The heating system was no longer technically up to date. This resulted in excessive energy consumption, excessive CO2 emission and excessive costs. A signifi cant investment was required to install a modern, economical heating system that could demonstrably save energy costs.

The solution was contracting. The heating contractor Cofely undertook the fi nancing and the technical implementation of the new heating system. The costs of the fi nancing were offset against the energy costs saved over the years.

The new system

Gas condensing boiler with high standard effi ciency factorThe ELCO heating concept offered convincing, modern tech-nology. One of the three former high-pressure water boilers was dismantled. In its place, two RENDAMAX 3410 gas con-densing boilers with a heating power of around 4 MWh were installed. The other two boilers will temporarily remain in place as a back-up. The RENDAMAX 3410 gas condensing boilers offer very high energetic performance. That means that, because of the high modulation, long burner times and signifi cantly lower run-up emissions are achieved. The patented stainless-steel premix burner has remarkably low noise and pollution emissions and a high standard effi ciency factor of 103 %.

There are also signifi cant economical benefi ts arising from the wide modulation range of 470 kW to 3,860 kW. This permits considerable energy savings – and at the same time is easy on wear parts and reduces maintenance effort.

Building project: SNOW DOME, Bispingen

ELCO turns on the heat in Europe’s largest indoor ski slope

The SNOW DOME in Bispingen, on the A7 motor -way near Hamburg, is regarded as the most modern indoor ski slope in Germany. A track 300 m long, equipped with a 6er lift gives young and old the opportunity to use skis and snowboards all year round, in any weather.

In the spring of 2006, the planning offi ce of Wenzel in Lüneburg requested tenders for the planned heating system. After several presentations, ELCO received the order. The recommended two gas condensing boilers, which work primarily for the ventilation, appealed to the technical partners on several counts: compact construction, low weight, low water content and a wide range of modulation for demand-oriented, energy-saving warmth. The Longlife service contract for guaranteed reliability and fi xed maintenance costs rounded off the so -lution package perfectly.

Energy-saving heating performancecoolly calculated

The starting point

In the spring of 2006 the planning offi ce of Wenzel requested tenders for all technical systems in the SNOW DOME. Con -struction of the indoor ski slope began in May 2006.

The required boiler system was to have a power of about630 kWh overall. The tender was for a cascaded double boiler: one heating boiler for the base load, and a second one for peak loads.

The new system

ELCO succeeded in winning over the responsible heating com-pany with their competence in the area of condensing boilers. The types that were selected were the RENDAMAX 2906 with 387 kW and RENDAMAX 507 with 247 kW. The ELCO gas condensing boilers are characterised by very compact dimen-sions, low weight and the fact that they can be completely stripped down.

The extremely low noise and pollutant emissions – mean noise pressure level at 1 m distance from boiler < 52 db(A), NOx < 35 mg per kWh – make these boilers the most environ-mentally friendly of their kind. These values are achieved by the series installation of air-intake and exhaust-gas resonance muffl ers combined with elastomer sound-insulation feet, and by the water-cooled pre-mix burner system.

Because of the wide range of modulation (control range of up to 1:5) and the very high standard effi ciency factor of up to 110.8 %, these boilers enable ELCO to achieve a reduction in fuel costs of around 15 % compared with conventional hea t-ing systems. Thanks to the small dimensions and the wide, infi nitely adjustable range of modulation, the boilers cause extremely slight stand-time losses.

Energy-saving contracting for Public Utilities, Weiden

Long-term guarantee gives planners a reliable basis for calculation

A unique assurance of guarantee by ELCO made it possible to implement an energy-saving contract project in Weiden (Oberpfalz). The contracting helped the town to open up extremely economical potentials for savings in their properties. The ELCO service contracts covered the entire run time of the project of up to 12 years. This gives the contractor, an association of engineers and planners, a long-term, reliable basis for calculation and planning with regard to the heating equipment. In total, the order in Weiden embraced 44 of the latest gas con -densing boilers. The result now is that the increase in energy effi ciency reduces the energy consump-tion and the CO2 emission, year in, year out, by more than 25 %. The savings in energy costs are distributed, with the contractors fi nancing their costs and the town council its investments.

Modern heating technology opens upgreat potential for energy savings

The starting point

28 properties with excessive energy consumptionThe heating systems in Weiden, as in many other munici-palities, were technically obsolescent and over-proportioned. High waste-gas temperatures, lack of effi ciency through the year and high losses through heat dissipation meant that, year after year, tens of thousands of Euros more than necessary were spent on heating costs. Those responsible at the Town Council were well aware of this, and that a lot of energy can be saved with modern technology and opti -misation of the hydraulics and the mode of operation. But who was to provide the investments? The problem, not only in Weiden, was the narrow budget.

The solution

The Association for Energy-saving Contracting (ESC) decides on ELCOThe contractor in Weiden was an association of planners and engineers with an offi ce in Berlin. They chose ELCO’s well thought out overall solution in preference to competi-tors of repute. One convincing argument was the compre-hensive service package with its fi xed price and guarantee assurance for the entire project run-time of twelve years. In addition, ELCO was able to meet the planners’ profi le with regard to equipment, function and power of the delivered heating boilers.

The new system

Gas condensing boiler with stainless-steel surface burner The Weiden order embraced 40 fl oor-mounted gas conden-sing boilers with customer-specifi c modifi cations, and four wall-mounted gas condensing boilers.

For optimal regulation of the performance, 17 of the systems were implemented as cascaded solutions. Because of special requirements, the boilers had to allow an operating mode with very great differences between fl ow and return temperatures without suffering damage.

In addition, there were to be communication and control capa -bilities for centrally controlled, power-dependent operation of the boilers. The contractor can thus fully control each boiler from his central offi ce in Berlin.

Temperature resistant and compact The contractor relies on a wide spread of temperatures, in orderto be able to transmit a lot of energy with a low volume of water. At the same time, the return temperatures should be as low as possible, so as to allow effi cient utilisation of the condensation. These extremes – very cold water into the boiler, and very hot water out of it – presents material problems for many of the boilers on the market.

RENDAMAX 3400: Fast heat transfer, fl exible mounting RENDAMAX 3400 gas condensing boilers offered the ideal so lution because of their special design, with low volumes of water and compact heat exchangers for fast, direct, effi cient heat transfer.

Further benefi ts are the low space requirement, reduced electricity consumption, and fast, fl exible heat transmission. And one other aspect turned out to be important. The access paths to the boiler rooms were often very narrow, but because the ELCO boilers can be stripped down and reassembled quickly and easily on site, this caused no problems.

Optimised waste-gas systems Finally, special attention was paid to the waste-gas systems – for the purpose of optimising the combustion process, and to prevent a negative infl uence on the calculated performance data right from the start. ELCO suggested always operating the systems with under-pressure. With appropriate air-bleeder equipment, the behaviour of the chimney can then be kept under control at all times.

Energy-supply contracting for a block of fl ats

ELCO ensures more energy and cost effi ciency

The property to be renovated was a block of fl ats in the Berlin district of Kreuzberg. The problem was an obsolete heating system with excessive energy consumption. Renovation of the heating system was urgently required, on one hand to save energy, and on the other hand to increase convenience. The housing administration decided on energy-supply contracting. The contract was awarded to GASAG WärmeService (GWS) from Berlin. The GWS chose an advanced solution from ELCO: the RENDAMAX 3406 and RENDAMAX 3408. The system was put into operation at the end of the year 2009.

Thanks to the renovation measures combined with a high-performance block-type thermal power station, it was possible to signifi cantly improve the energy balance of the block of fl ats. This resulted in savings of 19 %.

The new system

Gas condensing boilers for high performanceThe GWS decided on modern energy-saving technologyby ELCO – the RENDAMAX 3406 and RENDAMAX 3408 gas condensing boilers – in place of the obsolete oil-fi red heating boilers. In addition, a modern block-type heating power station was installed, with an electrical output of 49.5 kW and a thermal output of 97.2 kW. Taking both components boiler and heating power station, into account, a very high effi ciency of about 96 % was achieved in the fi rst year after commissioning.

The ELCO gas condensing boilers are characterised by their high heat output, low consumption and low emission values. In addition, they are compact and space-saving. The ener-getic performance of ELCO boilers is very high.

Thanks to the infi nite adjustment of the modulation of the burn-er power, the burners adapt precisely to the actual heating demands in the building. The high modulation shortens the burner running times, and the run-up emissions are signifi -cantly reduced. Thanks to the wide modulation range of 470 – 3,860 kW, great quantities of energy can be saved. This is easy on the wear parts, and reduces the maintenance effort. With the advanced boiler management with load regulation and digital, automatic burner controls, it would also be possible to arrange several boilers in a cascade.

Modern heating technology that convinces with effi ciency

The services to match the heating system:

Modern heating systems are crammed full of sophisticated tech-nology and complex electronics. So it is very important, especially in commercial and public buildings, to have a system with a “full service history”. Failure of the heating can have serious conse-quences in these cases: loss of production, curtailment of rents, or suits for damages. Schools and hospitals must also be able to rely on fault-free operation. That is why ELCO offers the matching services for each heating system and each requirement, from pro -fessional commissioning through regular maintenance to many years’ service and system reliability. Ensure long-term reliability of function and cost stability with an ELCO maintenance contract.
