RadiCal™

Improves energy efficiency and comfort whilst reducing bills.

A radiator that produces more comfort at less costThe power we use in buildings accounts for 40% of global consumption. And that has a massive impact on the environment. But with smarter energy management, our buildings can emit up to 60% less CO2. That’s something the European Union are moving towards, by making energy consumption standards stricter.

At Stelrad, we believe the heating industry has a major role to play, by developing systems that work so efficiently that they produce more heat at lower temperatures.

That’s why we’ve developed Stelrad Radical, the energy saving radiator. It produces more radiant heat than traditional radiators - saving energy while raising comfort levels. At less cost to the user, and to the environment. That’s a Radical step forward.

A radiator that reduces energy bills by up to 10.5%Your choice of radiator determines how comfortable the heating in your home feels. And how much that comfort costs. You know how a draught free room at 20°C can still feel uncomfortable?

•The energy saving radiant heat of the Stelrad Radical will soon fix that. And with the outstanding energy efficiency delivered by its preset valve, it reduces your bills by up to 10.5%, too.

•Thanks to the controlled flow of our unique direct intake technology, the water in the front panel reaches a temperature up to 50% higher than in a traditional radiator

•The Stelrad Radical energy saving radiator reaches its maximum temperature 23% faster than a traditional radiator

• It reaches its optimum performance level while a traditional heater is still heating up

•After only 2 minutes it offers up to 50% more radiant heat

•With higher radiant heat, the feeling of 20°C can be achieved at a lower temperature setting

The Stelrad Radical energy saving radiator’s unique and innovative technology raises comfort levels. And by working more efficiently, it reduces energy bills - with a saving of up to 10.5%.

Raising comfort levels with more radiant heatA radiator that delivers more heat, more efficiently.

Domestic heating is usually based on convection and radiation. With convection heating, hot air rises from the heating elements, cools down, descends via the wall and is heated again. With radiant heating, infrared radiation is sent directly around the room regardless of airflows like wind or drafts.

Radiant heat heats up the room, furniture and people, and is reflected back to create a more comfortable feeling similar to the rays of the sun. And standing in the sun always feels much warmer, even if the surrounding temperature is no higher than in the shadow - because it is radiant heat.

Test conditions: radiator K2, height 600mm, length 1000mm, temperatures 70/55/20°C.

At 8 minutes,with 50% ofnominal flow

At 8 minuteswith nominal

flow

Up to 50% more radiant heat means more comfort - at a lower costThese thermal images demonstrate the improved radiant heat of the Stelrad Radical radiator.

The measurements show that the Stelrad Radical energy saving radiator offers 1.5 times more radiant capacity at 50% of the nominal flow (which offers 90% of the nominal heat output) compared to a traditional radiator.

So depending on the radiator size and type it is compared to, the Stelrad Radical energy saving radiator offers up to 50% more radiant heat.

Supported by a RIBA & CIBSE CPD programme

Stelrad are certified as a member of the RIBA and CIBSE CPD Providers Network. This means we can provide RIBA and CIBSE approved CPD material to architects and other specifiers. An hour-long programme delivered by a member of the Stelrad team delivers information on every aspect of the Stelrad Radical energy saving radiator and its application

Energy savings tested, assessed and declared by KIWAKIWA is a highly respected Pan European institute providing internationally recognized declaration services for systems and products. As an independent expert, KIWA also carries out specialist testing, and the KIWA Gas Technology division has rigorously trialled the Stelrad Radical radiator to assess and declared its energy saving performance

CompatibilityThe Stelrad Radical radiator is compatible with the following:

• Gas boilers

• Electric boilers

• Solar PV

• Ground source heat pumps (GSHP)

• Air source heat pumps (ASHP)

• Biomass installations

cpD

• In a traditional radiator the heat generated consists, on average, of 80% convection heat and 20% radiant heat - limiting the feeling of warmth

• The Stelrad Radical energy saving radiator increases radiant heat by up to 50%

So the comfortable feeling of a room at 20ºC is achieved at a setting of 1 degree less (or even lower).

Radical radiator

Standard radiator

A radiator that heats the room, not the wallTraditional radiators are as warm at the back as they are at the front. So valuable energy is wasted, as the heat goes into and through the wall.

The unique and innovative technology of the Stelrad Radical radiator changes all that. The flow connection to the front panel and the return connection into the back ensures that you feel warmer, faster.

And thanks to the higher radiation from the front panel, the back panel is much cooler than with other radiators. So up to 9% less radiant heat is lost through the back of the radiator.

That’s not just good for comfort levels. It also means the heating system is more efficient, which reduces bills - and CO2 emissions.

Fully compatible with renewable energy resources

The Stelrad Radical energy saving radiator is perfectly suited for both solo and multiple heating installations. It can be connected

to a modulating gas or fuel burner and is compatible with all kinds of low temperature systems, such as heat pumps, solar cells and biomass installations.

Faster heating means less CO2 - and lower energy billsHigher radiant heat levels and front panel temperatures combine with other benefits to reduce bills and CO2 emissions.

Heating up fully in less timeThanks to its unique flow pattern, heat up times are dramatically shorter for the Stelrad Radical compared to a traditional radiator.

1. Directed flowHot water is directed into and around the front panel. In a traditional radiator the water flow divides in parallel to front and back panel.

2. Distribution of hot waterHot water rises in one water channel and is distributed equally over the front panel. A unique system then directs it to the back panel where it is spread equally over the back panel water channels.

3. Faster heat upThe front panel of the Stelrad Radical radiator reaches a temperature of 62.5°C after 8.5 minutes. At that time, the front panel of a traditional radiator is at 59.3°C. It only reaches its maximum temperature after 11 minutes, by which time the Stelrad Radical has already been operating at maximum for 2.5 minutes.

Preset thermostatic valveThe thermostatic valve regulates the water supply in the radiator. This valve is preset in the factory according to the radiator’s size, which guarantees optimum efficiency.

Central connectionThe connection coupling of the Stelrad Radical is located in the middle of the radiator. This means that the location of the connection no longer depends on the length of the radiator, so pipes can be laid down early in the project with no need to know the size of the radiator.

RadiCal™

Simple and quick to connect with Hydro Block (H Block)With the 3⁄4” male thread, the H Block’s central connection means you can connect pipes directly to the Stelrad Radical radiator with additional couplers. This reduces the risk of leaks and improves the installation speed.

The H Block connects the radiator to the flow and return pipe and has a built-in drain off function, valve isolator and a lock shield for ease of installation and servicing.

•TwoHBlockconfigurationsareavailable:with straight connections for pipes coming from the floor or angle connections for pipes coming from the wall.

•TheHBlockpackalsoincludesachoiceofcoupling pieces to connect the H Block to the pipes - either 10mm or 15mm.

Installers should order a completed unit based on the appropriate H Block variation.

Left or right side valve positionThe Stelrad Radical radiator’s valve can be mounted on either the left or right side without having to adjust the supply and return pipes. (K2 only).

Preset valves - environmentally friendly and energy efficientEvery Stelrad Radical radiator is equipped with a preset valve, which enhances the efficiency of the system and reduces energy consumption.

This valve is preset in order to control the water flow, producing maximum efficiency at optimum temperature - and is an essential element in the Stelrad Radical energy saving design.

You can recognise the setting by the coloured valve closure (yellow, white, red, black or blue). The default setting is matched to the heat output of the radiator at system temperatures of both 70/55/20°C and 55/45/20°C.

Factory presetting conditions: - heat outputs at 70/55/20ºC (∆t = 15°C ) - pressure drop ∆p = 100mbar

For other system conditions, the valve can be readjusted (or replaced) according to preset tables 4360 and 4361 (using preset key - part of the hardware pack).

In one pipe systems the valve must be fully opened (position 8).

The benefits• No extra adjustment time during

installation

• Optimal water flow in the radiator

• Higher efficiency of the condensing boiler through lower return temperatures

• Environmentally friendly

• Lower energy costs

• Compliance with Rule EnEV for hydraulic balance

Radical mounting template

35-115mm

115-155mm

?

UIN: 9223

Using the mounting template for the bottom connection of Radical radiators offers important advantages during the installation, e.g. leak testing the system without a mounted radiator.

The mounting template replaces the radiator during the installation, which reduces the total installing cost. Finishing tasks such as painting, tiling and applying wallpaper no longer require the removal and remounting of the radiator.

The radiator is mounted after all the finishing work, which guarantees a pristine condition on commissioning.

The mounting template consists of a bridging piece with 2 connections of 3⁄4” external thread on a centre distance of 50mm. As the wall distance depends on the radiator type, the mounting template offers multiple positions according to the available brackets.

For 1⁄2” INT - bottom connection(right, centre or left)

The mounting template can be used for tubes coming from the floor, as well as for tubes coming from the wall.

1

To mount of the template on the wall, the plumbing should have the correct wall distance.

2

Connect the plumbing to the template and conduct the leak test.

3

Once the concrete floor is finished the L-shaped part (and the extension) can be removed in order to paint, tile, to apply wallpaper. ATTENTION: the bridging part must remain on the plumbing to prevent pollution of the tubes.

4

Mount the brackets against the wall and remove the bridging part before the radiator can be installed. Note: Brackets should be mounted before removal of the bridging part, to eliminate any possibility of pollution.

5

ATTENTION: the mountingtemplate has a ¾” ext eurocone thread, for radiators with a ½” INT bottom connection, a ½” EXT x ¾” EXT piece is necessary.

extra performance to guaranteed standardsStelrad combine the most sophisticated production resources in Europe with substantial investment in testing and verification of performance data - which has helped us create high output radiators delivering heating performance that exceeds expectation.

Superb quality from design to installationOur radiators are specifically designed to minimise any movement, providing a tight, professional fit, that will remain in place, even after storage, transit and installation. Convectors are precision welded directly onto the waterways for greater efficiency and economy,

with flexible connection options for the highest of commercial and domestic application specifications.

Stelrad radiators are manufactured under ISO 9001 quality systems in the UK and every one comes wrapped in robust, practical packaging that will keep the product pristine, right through to installation. This clever packaging design allows installation to be completed prior to removal.

temperature tableFor systems not operating at ∆t50 the factors in the table below should be applied. The output of a given radiator can be obtained by multiplying the quoted ∆t50 output by the operating factor. Conversely, to derive a non ∆t50 output, divide the heat output required by the relevant operation factor. This ‘∆t50 equivalent output’ can then be used to select a radiator from the standard tables.

applicationsStelrad radiators are suitable for two pipe installations. For single pipe applications, it is advisable to use diversion tees in the pipework, as this will assist in obtaining design performance from the radiators. Although our radiators are suitable for Microbore pipework, the back tappings make them unsuitable for twin entry valves.

installationEverything required for installation can be found within each radiator’s packaging. Brackets are of a strong design, with open top and deep slots, which facilitate easy and secure installation. Plastic inserts seat the radiator precisely on the bracket

minimising expansion and contraction noise.

The neat nickel-plated plug and vent provide a watertight joint, whilst complementing the superior finish.

To facilitate easy one off replacement, nickel-plated brass extension pieces are also available, complete with sealing washer, in 20mm, 30mm and 40mm options. Recommended height from the floor to the base of the radiator is 150mm minimum. This allows adequate airflow when the radiator is placed on the bracket.

CautionWhen designing for domestic systems we recommend that the Stelrad radiators are only used in heating systems complying with British Standard Code of Practice for Central Heating for Domestic Premises BS EN 12828:2003 and BS EN 12831:2003.

Single feed, direct cylinders are not recommended as should interchange of water occur, fresh aerated water would enter the heating system, resulting in corrosion.

Water treatmentOn completion of the installation, the system should be properly flushed and filled in accordance with the British Standard Code of Practice BS 7593:2006 for the Treatment of Water in Domestic Hot Water Central Heating Systems, Part L of Building Regulations and Good Practice Guidance for Scotland.

After installation of a new Stelrad radiator the central heating system should be cleaned and flushed with cleaner to remove existing contaminants, flux residue and other installation debris which, if left, can cause damage to the new radiator. Afterwards, treat the system with an inhibitor to ensure long term protection against corrosion and limescale.

A comprehensive range of quality chemicals including inhibitors, cleaners, leak sealers and noise reducers that protect and maintain central heating systems can be obtained from:

two coat paint process

Each Stelrad radiator is subjected to a multi stage cleaning process before the paint is applied. This involves several rinsing stages, including an iron phosphate and demineralisation rinse. The first coat of paint is applied by electrophoresis and the radiator is then stoved and cooled. The second powder coat in warm white (RAL 9016) is applied and the radiator goes through a final curing stage. It is then allowed to cool, prior to packaging.
