oUnderfloor Heating Overview

With underfloor heating the air temperature is hottest at floor 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 floor level and hottest at ceiling level resulting in high heat loss through the ceiling which means higher energy usage and fuel bills.

Underfloor 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 underfloor 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 underfloor heating. There are no cold spots, no hot heads and no cold feet !


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

Eco-friendlyUnderfloor 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 efficientUnderfloor heating is the most energy efficient way of transferring heat into any room since it works almost entirely by radiation, from the floor surface onto other surfaces in the room and from there heating the airspace. This is a more natural form of heating and requires lower flow temperatures due to its increased surface area.

Healthier environmentRadiant energy is emitted by the floor 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 floor level, where we want it to be. This radiation method creates fewer draughts and dust movements and explains why underfloor 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

Underfloor heating systems provide ideal comfort levels for the home, office, retail environment, leisure or industrial complex. They are highly efficient, proven, durable and environmentally friendly.

Underfloor 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 underfloor 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 efficient 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.

How Underfloor Heating and Cooling Works

Conventional Radiators Underfloor Heating

Comparing underfloor heating with radiators

Underfloor heating works by circulating warm water through a series of continuous loops that are fitted underneath your floor creating a large radiant surface that heats your room from the floor upwards. This radiant form of heating is much more comfortable than the convected heat provided by radiators which draws cold air across the floor before heating it and then convects the warm air upwards towards the ceiling.

Underfloor cooling works in very much the same way as underfloor heating except the energy transfer is reversed. Where underfloor heating radiates thermal energy from the floor surface into the air space, underfloor cooling absorbs radiant energy from the warm air in the room as it passes over the cooler floor surface. This reduces the overall temperature in the room as the cool floor 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 flow water with the cooler return to achieve the reduced temperatures required by underfloor 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 underfloor heating heats the whole floor area, the water temperatures required are much lower than that of radiators.

What are the Main Components of an Underfloor Heating System?

WMS Underfloor 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 underfloor heating design is unmistakably the most important part of any underfloor 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 efficient 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 floor, typically either a screed or timber floor but fixing methods change according to requirements. Our pipes can heat floor areas at low water temperatures and are designed to be effective with almost any floor finish including ceramic tiles, linoleum, wood and carpets.

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

COMPONENTS

Underfloor heating pipe is a crucial but unseen component of every underfloor heating system and at WMS we only fit the very best. Our standard 17mm pipe has a robust, 2mm, five layered polyethylene tube that uses the very latest PE-RT technology.

It is manufactured in Europe to an industry leading specification. The 2mm thick pipe wall is made up of five separate layers and contains an oxygen barrier to prevent the ingress of water from the pipe into the surrounding screed through condensation and to prevent oxidisation by stopping any ingress of water into the pipe.

> Pipe > Systems > Controls


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 efficient 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 benefits 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 flexible during the design stage and can quickly accommodate any alterations to the layout and other requirements as they are specified 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 and Pumpset: Confidence at the Heart of the System

Manifolds and pumpsets are at the heart of any underfloor heating system since they control the flow and distribution of water from the heat source (eg. boiler, heat pump) to each underfloor pipe circuit. Our manifolds are supplied with a factory fitted mixing valve, ball valves, drain valves, temperature and pressure gauges. There is also a balancing valve for each loop.


WMS Underfloor 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 configured 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 underfloor heating. The nature of under floor heating to cover the whole floor 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 floor 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 75 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 flexible 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 Underfloor Heating pipe is a five layered polyethylene tube using PE-RT technology that is manufactured to our own specification and composed of five bonded layers. It contains an integral EVOH oxygen barrier layer to prevent oxygenation of water inside the system.

Control Systems

Controls are an essential part of any heating system as they create your environment in the most efficient 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 underfloor 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 profiles. Profiles 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 floor insulation is installed over the subfloor on to which cliprails are then fixed 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 underfloor heating pipework is laid in continuous loops and clipped down in accordance with the underfloor heating design drawings. Once complete, the system is pressure tested and witnessed to finalise 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 notified if a liquid screed is being used, as the insulation must be sealed to provide a watertight base. Where controls are required from WMS, these will be supplied as ‘second fix’ items for others to fit.

AmbiFloat 10 system requires a flat and level sub floor for the insulation to fully support the floor finish on top. The insulation is pre-grooved to take the underfloor heating pipework and over laid with foil to assist the distribution of heat. The polystyrene insulation panels are custom made for each project to suit the underfloor heating design drawings. The system is then overlaid with a fully floating floor deck onto which your floor finish is applied. In the case of wooden floors, 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 floors, acoustic floors through to overbattened floors.

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

When using the AmbiFloat 20 and AmbiFloat 30 systems, the timber subfloor should be installed in the normal way over the joists/battens onto which your finishes are applied. Engineered timber floors can be fixed directly to the joists/battens.

Before the underfloor heating system is installed, insulation should be laid between the joists/battens and should be laid as close as possible to the underside of the pipework to maximise the heat 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 flooring is being laid to highlight any potential damage to the pipework during this process.

Controls and pumps (if required) are supplied as loose items for others to install. An ‘as Installed’ drawing will be issued after the installation for the client’s records.

> Low profile modules allow easy access to floor void underneath

> Modules can be easily dismounted and repositioned when office layout changes

The AmbiAF system is uniquely designed to incorporate underfloor heating into a raised access floor construction. A U-shaped bracket is mounted on to the pedestals on to which insulation profiles 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 underfloor heating pipework is installed without joints within the floor and piped back to the underfloor heating manifold as detailed on the right. The concept is simple but does require liaison with the access flooring specialist during the design and installation.

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

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

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 efficiency and sustainability. A well insulated building combined with underfloor 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 efficient than standard homes.

The underfloor 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.


3 City Place, Gatwick

The City Place development consisted of the design and construction of a new high quality four storey office block, providing a clean working area to over 500 personnel. The majority of its structure was made up of glass, with panels extending from floor to ceiling on each level creating an open and spacious impression as well as providing plenty of natural daylight.

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

The underfloor installation comprised of our superior AmbiClip screeded floor system, laid over a polythene separating layer and 80mm Celotex insulation on top of the concrete subfloor. The main office areas utilised an access floor 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 five layers with an internal and external oxygenation barrier to prevent water ingress into the system. It is guaranteed for 75 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 efficient market gardening visitor centre with interactive displays, a cafe, a shop and offices.

The building boasts over 4.5Km of high performance, 17mm underfloor 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 AmbiClip system for the ground floor with a 75mm fibre screed overlay which was power floated to a smooth finish. For the underlying insulation we used a 100mm polyurethane Celotex board with foil on both sides to maximise the reflection of heat upwards. A damp proof membrane/separating layer was laid underneath to prevent moisture permeating through the floor.

WMS designed a bespoke solution for the upper floors with a hybrid screeded floor between timber joists. This had excellent thermal efficiency 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 flow is varied in relation to ambient air temperature. The PE-RT five layer UFH pipe used has a 75 year guarantee and reflects 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 magnificent penthouses with private gated grounds of almost two acres that include woodland with mature cedar trees.

The classic design layout and interplay of natural daylight give a unique sense of space in each apartment, raising the standard of living to a new level of enjoyment. Terraces and balconies are generously proportioned and afford timeless views across the neighbouring countryside. The property also benefits from an underground car park served by lifts to each floor.

To complement this prestigious development, WMS Underfloor Heating was chosen to supply a system that was capable of providing exceptional comfort and control. WMS was contracted to construct the whole floor build up from laying the acoustic detail through to screeding. The turnkey contract

assisted the developer by reducing the stress and responsibility that is normally involved in coordinating a number of trades.

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. Renewable energy benefits include rainwater harvesting, a ground source heat pump – utilising buried coils and thermal roof panels, working alongside the underfloor heating system. The 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 underfloor heating systems work at lower temperatures and stay on for longer periods lends itself towards the renewable heat pump technology.

As every new build school has to comply with the relevant environmental standards and regulations, underfloor heating has become increasingly popular. Running costs have been proved to be up to 30% cheaper than the conventional radiator systems, as well as a generally cleaner and safer form of heating.

The practical application of keeping the wall space free from any surface wall heaters is another added benefit.

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 floors including an excavated lower ground floor level. The spaces created are of high quality and serviced to meet modern museum standards. Underfloor heating was used to heat part of the refurbishment in the form of our AmbiClip screed floor system. The even and gentle form of temperature control that underfloor 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, office 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.


Bentley Priory, Stanmore

The RAF Bentley Priory site, which covers 50 acres in Stanmore, North London, was purchased by Barratt Developments in 2002 for a development of 89 luxury residential units varying from apartments to single detached houses.


Built in 1766, Bentley Priory itself is a grade 2 listed building that provides the area with an air of historic importance. With past owners including John Hamilton, 1st Marquess of Abercorn and the Dowager Queen Adelaide, it was acquired by the Royal Air Force in 1926 and became the headquarters of Fighter Command during the Second World War.

The RAF continued to occupy the site until 2008 when it relocated to its Northolt facility. As part of the redevelopment, the historic former officers’ mess was renovated to house the Battle of Britain museum. The significance of the site is further emphasised with Spitfire and Hurricane fighter planes mounted on poles a few metres above the ground.

The first phase involved the construction of 12 crescent houses. These three storey properties had underfloor heating throughout with all systems designed, installed and commissioned by WMS.

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 fleet-footed witch in the Scottish legend of Tam O’Shanter, the ship was almost destroyed by fire 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.

CASE STUDIES

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 floor construction in the dry berth area, underfloor heating panels had to be specially designed by WMS engineers. The design uses a bespoke, raised floor

build-up that is supported by specially adapted pedestals. These pedestals support large, pre-grooved calcium sulphate boards which are laid across the entire surface area. The underfloor heating pipe work is then laid flush within each panel ready for the final floor surface to be laid on top. The complete system is designed to achieve a heat output of at least 70 watts per metre.

This unique design was specially developed by the WMS design team for this project.
