oUnderfl oor Heating Overview

With underfl oor heating the air temperature is hottest at fl oor level, where it is needed and reduces as it rises to the ceiling. Conventional radiator systems have the opposite effect where air temperature is coolest at fl oor level and hottest at ceiling level resulting in high heat loss through the ceiling which means higher energy usage and fuel bills.

Underfl oor heating can also achieve comfort levels of heating with air temperatures that are around 2°C lower than other systems.

These factors mean that when designing an underfl oor heating system, less allowance is required for building height which means lower energy requirements for buildings with high ceilings such as warehouses, theatres, churches, schools, barn conversions and leisure centres.

Energy reaches into every corner of the room with underfl oor heating. There are no cold spots, no hot heads and no cold feet !


ooverviewComplete fl exibilityWith multiple control options, your comfort is achievable at the press of a button. Underfl oor heating is invisible and being under the surface gives you a totally fl exible layout with no radiators to limit interior designs and furniture arrangements. Underfl oor heating can also add value to property through its silent operation and lower running costs.

Eco-friendlyUnderfl oor heating is an integral part of the green revolution in contemporary heating and cooling solutions. It requires much lower water temperatures than conventional heating systems, it can be connected to a range of eco-friendly heat generators like solar panels and geo-thermal heat pumps making it the natural partner for many heating and cooling solutions in the renewables sector.

Energy effi cientUnderfl oor heating is the most energy effi cient way of transferring heat into any room since it works almost entirely by radiation, from the fl oor surface onto other surfaces in the room and from there heating the airspace. This is a more natural form of heating and requires lower fl ow temperatures due to its increased surface area.

Healthier environmentRadiant energy is emitted by the fl oor making it the warmest part of the room with the air cooling as it rises, with the coolest air at the ceiling and the warmest air at the fl oor level, where we want it to be. This radiation method creates fewer draughts and dust movements and explains why underfl oor heating is considered to be the most comfortable and healthiest form of heating. For those who have it, few ever want to return to conventional systems.

OVERVIEW


The Complete Solution

Underfl oor heating systems provide ideal comfort levels for the home, offi ce, retail environment, leisure or industrial complex. They are highly effi cient, proven, durable and environmentally friendly.

Underfl oor heating also requires less energy than conventional heating systems, they are completely silent in operation, emit zero emissions and do not rely on blowers or hot surfaces to distribute heat throughout your building.

During the summer months our systems can be switched to provide underfl oor cooling by simply running cool water through the system. This absorbs heat from the surrounding air and creates a pleasantly cool environment.

Our aim is simple. We want to enrich your way of life by offering you a heating system that is more comfortable, reliable, cleaner and much more effi cient for the future.

Driveway Heating and Snow Melting SystemsFully automated, radiant heat snow melting systems can be installed in small customised driveways, large commercial parking structures, ramps, loading bays, walkways and more.

Manifold The Ambiente stainless steel manifold is a piece of engineering excellence. Acting as the heart of the system, this sophisticated piece of equipment distributes warm water throughout the underfl oor heating system. > more information on page 22

How Underfl oor Heating and Cooling Works

Conventional Radiators Underfl oor Heating

Comparing underfl oor heating with radiators

Underfl oor heating works by circulating warm water through a series of continuous loops that are fi tted underneath your fl oor creating a large radiant surface that heats your room from the fl oor upwards. This radiant form of heating is much more comfortable than the convected heat provided by radiators which draws cold air across the fl oor, heating it and then convecting it upwards towards the ceiling.

Underfl oor cooling works in very much the same way as underfl oor heating except the energy transfer is reversed. Where underfl oor heating radiates thermal energy from the fl oor surface into the air space, underfl oor cooling relies on warm air passing over the cooler fl oor surface which absorbs radiant energy from the air and reduces the air temperature in the room. This process of passing chilled water through the fl oor keeps the fl oor area cool which continually absorbs warm air from the room.

1 2 3 The manifold distributes water from the heating source to the relevant zone. Manifolds will typically have a mixer valve to allow them to mix hot fl ow water with the cooler return to achieve the reduced temperatures required by underfl oor heating.

The heat source can be any type of water heater, from a conventional boiler powered by gas or electricity or any of the renewable energy sources, including ground source heat pumps and solar panels. Since underfl oor heating heats the whole fl oor area, the water temperatures required are much lower than that of radiators.

What are the Main Components of an Underfl oor Heating System?

WMS Underfl oor Heating can design, supply and install the complete system for you. Our manifolds are designed for connection to any heat source from a conventional boiler to ground source heat pumps or solar panels.

Supplied by others Supplied by WMS

The underfl oor heating design is unmistakably the most important part of any underfl oor heating system. Our dedicated design team produces accurate and comprehensive drawings for every system that we install, maximising performance for all our systems, guaranteeing that we will supply the most cost effective and effi cient solution for your project.

> Heat Source > Design > Manifold


4 5 6There are many variations of system type, consisting of pipe work that is set within the fl oor, typically either a screed or timber fl oor but fi xing methods change according to requirements. Our pipes can heat fl oor areas at low water temperatures and are designed to be effective with almost any fl oor fi nish including ceramic tiles, linoleum, wood and carpets.

Effective controls are an essential part of any heating system especially since around 90% of your underfl oor heating system is actually underfl oor. The control system provides a user interface with your heating system and can be as simple or as complex as your requirements. Underfl oor heating temperatures are measured by room thermostats that are situated throughout the building with fl oor probe options available for sensitive fl oors.

COMPONENTS

The pipe is at the heart of every underfl oor heating system and at WMS we make sure that we only use the very best. Our pipe is a fi ve layered polyethylene tube that uses the latest PE-RT technology.

It is manufactured in Europe to our own specifi cation and contains an integral EVOH oxygen barrier layer which prevents oxygenation of water inside the system. This is a very important feature because air in the system can cause air locks or corrosion.

Our dedicated CAD design team produces accurate and comprehensive drawings for every system that we install, maximising performance for all our systems and guaranteeing that we will supply the most cost effective and effi cient solution for your project.

We also supply comprehensive wiring diagrams showing how the system should be wired, by your on-site electrician. Each diagram provides clear, concise and comprehensive electrical layout details for the system.

Our design team benefi ts from our unique, approved design system that includes heat loss and output calculations. We provide detailed CAD drawing layouts showing exact positioning of all UFH pipework, controllers, manifolds and bathroom/kitchen layouts to thoroughly assist the install process and ensure all requirements are met.

Having our own design team means that we can be much more fl exible during the design stage and can quickly accommodate any alterations to the layout and other requirements as they are specifi ed by the architect, builder or client. We can prioritise these changes in our system and minimise any delays.

These drawings are also supplied to our clients for their own records. We also keep all our drawings in our electronic database for future reference and if clients require this information we can readily supply it.

DESIGN

“At WMS, Excellence comes as standard”


Manifold: Confi dence at the Heart of the System

Manifolds are the heart of any underfl oor heating system as they control the fl ow and distribution of water from the heat source (boiler, heat pump etc.) to the individual underfl oor pipe circuits. Manifold mixing valves can also be attached to the manifold to regulate the water fl ow temperature. A pressure gauge ensures that the system is properly pressurised.


WMS Underfl oor Heating manifolds are manufactured in Europe and represent another quality addition to our range of components. Made out of stainless steel and tested to rigorous standards, they are available in various sizes from just two ports for a small system, up to 12 port versions for areas up to 200M2 . In order to ensure total durability and reliability, our systems are tested to 4 bar for operation within systems that typically operate on less than 3 bar pressure.

Following installation, our commissioning engineers provide a comprehensive balancing and commissioning service to ensure the system is working perfectly before handover.

At handover we also provide a full list of documentation including a set of ‘as installed’ drawings, detailing exactly where our pipes have been laid and how they are confi gured in your system. We also provide a comprehensive operating and maintenance (O&M) handbook which gives details of all manufacturing and installation warranties.

See the ‘site assist’ section in this brochure for details of our unique aftercare and planned maintenance service contracts that are available for our systems.

MANIFOLDS


Oxygen diffusion is a very important factor within underfl oor heating. The nature of under fl oor heating to cover the whole fl oor area with pipe at relevant spacings creates a huge surface area of plastic, making it vulnerable to its surroundings. It is then essential that the pipe has a very low level of oxygen permeability so that oxygen cannot permeate into the pipe work and cause unnecessary damage and costs. A standard plastic pipe would not meet this level of oxygen permeability.

The pipe is installed with no joints within the fl oor and even when a pipe does need to be joined after the installation, a simple procedure of exposing and reconnecting the two ends is all that is required. Ambiente® pipe is supplied with a 50 year product guarantee. However, assuming the pipe is not disturbed, it is expected to out live the life of the building itself in the vast majority of cases.

PE-RT pipePE-RT stands for ‘polyethylene at raised temperature resistance’. Polyethylene has excellent properties at high pressures and temperatures as well as being very fl exible and easy to use. It is non-corrosive and has very good resistance to frost. It is also creep-resistant and has a high impact strength, which means that if the pipe is distorted it will return to its original shape within a short period of time. The outer layer protects the oxygen barrier from mechanical damage, moisture and other damaging materials.

Polymer adhesiveA functionalised polythene that acts as an adhesive layer between the polyethylene and the oxygen barrier.

EVOH oxygen barrierMade of ethanol vinyl alcohol that prevents oxygen diffusion at up to 80°C.

PE-RT Pipe: The Hidden Quality

WMS Underfl oor Heating pipe is a fi ve layered polyethylene tube using PE-RT technology that is manufactured to our own specifi cation and composed of fi ve bonded layers. It contains an integral EVOH oxygen barrier layer to prevent oxygenation of water inside the system.

5 Individual programmable room temperature control with BMS integration

From any point in the building and online. Using BMS compatible control system you can use it to control your central heating system, integrate the boiler and control other performance monitoring equipment.

Control Systems

Controls are an essential part of any heating system as they create your environment in the most effi cient and cost effective way possible. This means ensuring that your system only operates when required and for the minimum period of time.

There are various methods of doing this but all are managed by your control system with various levels of integration between the heating zone, heat source and outside temperature. The control system must be accurate and sophisticated as well as easy to use!

Room temperature control for underfl oor heating is measured by ambient room temperature controllers that are located in each zone. These are linked to the local manifold wiring centre where commands are sent to various relays and other outputs that require a signal.


CONTROLLERS

Designed to work with our low voltage thermostats, the Ambiente® touchpad provides central control of your heating system. It features a colour touch screen capable of controlling of up to 32 thermostats. Each thermostat can be individually named allowing you to easily identify and adjust each zone on the network.

A new feature is the ability to program profi les. Profi les are a stored set of comfort levels that can be applied to a group or rooms as and when required. Remotely program the comfort level of all the networked thermostats from one central point and copy program settings from one thermostat to another across the network.

Our controllers can be either hard wired or wireless and sometimes interfaced with your Building Management System giving you full remote control including internet access.

Edge and fl oor insulation is installed over the subfl oor on to which cliprails are then fi xed to by both the adhesive backing strip and barbed staples (where WMS is not supplying the insulation, checks should be made to ensure that the insulation is compatible with the cliprail system). Once the cliprails are secured in position, the underfl oor heating pipework is laid in continuous loops and clipped down in accordance with the underfl oor heating design drawings. Once complete, the system is pressure tested and witnessed to fi nalise the installation.

We recommend that the screeding process is scheduled to follow shortly after installation to avoid leaving the system vulnerable to damage. WMS should be notifi ed if a liquid screed is being used, as the insulation must be sealed to provide a watertight base.

AmbiFloat 10 system requires a fl at and level sub fl oor for the insulation to fully support the fl oor fi nish on top. The insulation is pre-grooved to take the underfl oor heating pipework and over laid with foil to assist the distribution of heat. The polystyrene insulation panels are manufactured per project to suit the underfl oor heating design drawings. The system is then overlaid with a fully fl oating fl oor deck onto which your fl oor fi nish is applied. In the case of wooden fl oors, this can be laid directly on to the insulation to minimise height buildup and maximise the heating output.

AmbiFloat 20 system has a wide range of applications from sprung sports fl oors, acoustic fl oors through to overbattened fl oors.

AmbiFloat 30 system is designed to fi t between timber joists supported by battens. This provides a neat solution incorporating the aluminium profi le and insulation into one product.

The timber subfl oor should be installed in the normal way over the joists/battens onto to which your fi nishes are applied. Engineered timber fl oors can be fi xed directly to the joists/battens.

The systems consists of aluminium diffuser plates being fi xed directly on to the battens/joists. The plates contain grooved channels into which the underfl oor heating pipework is installed in continuous lengths and piped back to the underfl oor heating manifold.

Before the underfl oor heating system is installed, insulation should be laid between the battens/joists and should be laid as close as possible to the underside of the pipework to maximise heating output.

The system is then pressure tested upon completion to 4 bar, witnessed by a site agent and signed off. The system should be left under pressure whilst the timber fl ooring is being laid to highlight any potential damage to the pipework during this process.

The AmbiAF system is uniquely designed to incorporate underfl oor heating into a raised access fl oor construction. A U-shaped bracket is mounted on to the pedestals on to which insulation profi les are installed. The 35mm x 100mm insulation panels are made of high density insulation and foiled to optimise the energy transfer. This contains a grooved channel into which the underfl oor heating pipework is installed with no joints within the fl oor and piped back to the underfl oor heating manifold as detailed on the right. The concept is simple but does require liaison with the access fl ooring specialist during the design and installation.

This system lends itself towards most of the common raised access fl ooring manufacturers and whilst providing a heating or cooling source, will still maintain full access to services within the fl oor void.

The system can take fl ow temperatures up to 60OC producing outputs between 50-60 w/m2. It can also be disassembled and relaid at a later date if required.

Fabrik, Coldharbour Lane, Brixton

The ‘Fabrik’ Coldharbour Lane development is the UK’s fi rst ModernaHus development. ModernaHus is a pre-fabricated house building system that was originally developed by Skanska for the Scandinavian housing market which they have adapted for the UK.

The main features of this project are a well-insulated building envelope combined with an underfl oor heating system and a central biomass boiler which feeds a site-wide district heating scheme to provide a truly energy effi cient and sustainable housing solution.

This development consists of two eight storey blocks offering 108 affordable one, two, three and four bedroom homes to tenants over a mix of shared ownership and social rented properties.

A key feature of this 5,497m2 development is its energy effi ciency and sustainability. A well insulated building combined with underfl oor heating results in reduced energy consumption, lower carbon emissions, improved living conditions and increased saleability. Each apartment in this development is up to 44% more energy effi cient than standard homes.

The underfl oor heating solution used is commonly known as the ‘tacker clip system’ and involves clipping the pipe work directly to a gridded plastic laminate which is pre-glued to an insulation layer. With this system the pipe can be laid in a spiral pattern to ensure an even distribution of heat.

The whole installation took just seven weeks to complete, which is an average of four apartments per day. WMS also undertook the controls package, providing individual room temperature control and time control to the hot water system.


Primark, East Ham, London

Primark is one of the UK’s most successful clothing retailers with over 220 stores in the UK, Ireland and Europe. Employing 36,000 people with a turnover of £2.7 billion, Primark has occupied a prime position on the British high street for the past decade.


The project involved the construction of a two storey extension to Primark’s existing store. Structural changes were made to accommodate new goods and customer lift shafts. Additional escalator pits were also dug out for future development and a new service yard and goods loading area were also constructed.

Total fl oor area was increased by 3,328m2 over two fl oors comprising both retail space and storage areas. The architects wanted a heating system that provided comfortable and

uniform heating across large areas without encroaching on the retail space. Underfl oor heating matched these requirements perfectly and it quickly became the preferred choice for this project.

WMS used an in-screed AmbiTak system to provide the uniform temperatures required, combined with superior quality Ambiente control systems allowing for variable temperature control to all areas.

The building is built in accordance with modern environmentally-friendly standards and is highly self-sustainable and energy effi cient. However, energy effi ciency is only acceptable when the design leads to a comfortable, healthy working environment. Underfl oor heating was considered to be the natural choice for this construction, providing a signifi cantly more cost effective and eco friendly solution as opposed to more traditional heating systems.

The underfl oor installation comprised of our superior AmbiClip screeded fl oor system, laid over a polythene separating layer and 80mm Celotex insulation on top of the concrete subfl oor. The main offi ce areas utilised an access fl oor allowing for services to run unhindered beneath.

Robust, 17mm diameter PE-RT pipe was used throughout this installation. The pipe has 2mm thick walls and is made up of fi ve layers with an internal and external oxygenation barrier to prevent water ingress into the system. It is guaranteed for 50 years although we would expect it to outlive the life of most buildings.


Holme Mills Heritage Centre

Holme Mills Heritage Centre is an original mill that has existed for over 1000 years and is located on the banks of the River Ivel in Bedfordshire. The Mills are a feature of sustainability with all its history in the growing of grain and vegetables. The structure is made from natural timber with many original beams and lathe and plaster render to the surfaces. This historic building has now been developed into an energy effi cient market gardening visitor centre with interactive displays, a cafe, a shop and offi ces.

The building boasts over 4.5Km of high performance, 17mm underfl oor heating pipe working alongside the latest technology Ambiente manifold sets. Individual, computerised room temperature and timer controllers are located throughout the building with strategically placed room temperature sensors situated in all areas.

WMS used an AmbicClip system for the ground fl oor with a 75mm fi bre screed overlay which was power fl oated to a smooth fi nish. For the underlying insulation we used a 100mm polyurethane Celotex board with foil on both sides to maximise the refl ection of heat upwards. A damp proof membrane/separating layer was laid underneath to prevent moisture permeating through the fl oor.

WMS designed a bespoke solution for the upper fl oors with a hybrid screeded fl oor between timber joists. This had excellent thermal effi ciency and maximised output.

The system was connected to a state of the art heat pump and operates with various set points including an outside weather compensating control where the temperature of the fl ow is varied in relation to ambient air temperature. The PE-RT fi ve layer UFH pipe used has a 50 year guarantee and refl ects both the building’s intrinsic ‘long lasting quality and sustainability’ and the ethical commitment of Jordans to secure this important building for the long term.


Bishops Park is situated off The Bishops Avenue. It is one of London’s most sought after addresses. The development consists of 24 luxury apartments and three magnifi cent penthouses with private gated grounds of almost two acres that include woodland with mature cedar trees.

The Architects involved were looking for a heating system that did not encroach on the teaching space as well as achieving maximum comfort, and wanted to maintain environmental standards at all costs. Underfl oor heating was the only solution.

The whole school was heated through the fl oor by a tacker system on top of a 50mm laminated polystyrene insulation. The 1,600m2 main building had a tight deadline with the entire system having to be installed in three days! WMS were able to achieve this without compromising our high quality of service.

The private school’s artifi cial sports ground supports its success in a wide variety of team games and individual sports. It also boasts a separate 250m2 music tutorial building, which contributes to the standards of schooling held to.

WMS have provided heating solutions in many educational buildings and are familiar with the requirements, quality of service, and fl exibility of timescales they require. We have a team of technical advisors to assist you as to every aspect of your project. We look forward to receiving your enquiry.

Designed by Charles Cockerell in 1845, this Grade I listed building is retained as the frontage for the new museum. The museum plays a key role in Oxford University’s policy of wider access as well as supporting university teaching and research.

The project consists of 8,812m2 of new build area, representing a 91% increase in area. The building is arranged over six fl oors including an excavated lower ground fl oor level. The spaces created are of high quality and serviced to meet modern museum standards. Underfl oor heating was used to heat part of the refurbishment in the form of our AmbiClip screed fl oor system. The even and gentle form of temperature control that underfl oor heating provides made it a natural choice of heating.

The building comprises 37 new gallery spaces for the permanent collection in addition to special exhibitions, a two-storey education centre with designated entrance, offi ce space for the curatorial and administration departments, study collection spaces for the public to view objects by appointment, a new loading bay and transit store for the secure and dry transportation of artifacts and exhibitions, conservation studios and ancillary facilities.


St. Charles Sixth Form College

The project involved the demolition of a sports hall to provide space for a new classroom block, sports facilities and the refurbishment of a multi-use games area.


The new facilities feature cross-laminated timber frame and walls, a balustrade staircase with stainless steel mesh and maple wood handrail, cladding and glazing. Energy renewable aspects include rainwater harvesting, a ground source heat pump – utilising buried coils and thermal roof panels, working along with underfl oor heating. The main focal point of the building is the state of the art solar shading panels on the exterior and roof.

Many cost saving innovations were used on the build including the use of Kingspan timber panelling. The College has been awarded BREEAM rating – VERY GOOD.The fact that underfl oor heating systems work at lower temperatures and stay on for longer periods lends itself towards the renewable heat pump technology.

Cutty Sark, Greenwich

Cutty Sark is the most famous tea clipper ever built and is the only one to survive. Built in 1869 and named after a fl eet-footed witch in the Scottish legend of Tam O’Shanter, the ship was almost destroyed by fi re in 2007. Following lottery funding and public donations it was decided to conserve the ship to its former glory and build an imaginative new visitor centre at the ship’s home in Greenwich Dock.

The project involved raising the 980 tonne ship by over three metres and constructing a glass canopy over the dry berth to protect the ship’s hull from the elements. This allows visitors to view the clipper’s uniquely shaped ‘built for speed’ hull from below. The new facility also has an indoor shopping area and a cafe.

Due to the unusual fl oor construction in the dry berth area, underfl oor heating panels were specially designed by WMS engineers. The installation featured a bespoke, raised fl oor

build up supported by pedestals holding large calcium sulphate pre-grooved boards to allow the underfl oor heating pipe work to be laid fl ush within each panel. This provided a completely fl oating fl oor slab that as the primary heat source, capable of achieving at least 70 watts per metre. This is a unique design and was created by WMS designers using our experience and knowledge of underfl oor heating and its wide range of applications.
