Where underfloor heating systems are used

Underfloor heating systems are suitable for both domestic and commercial applications often these can have distinct advantages, in public areas where exposed hot surfaces can be dangerous, nursing and residential homes for example. Gas, oil or solid fuel boilers can be used as the source of heat for any underfloor heating system. Condensing boilers may be particularly suited as the operation of underfloor heating systems allows them to operate in their most efficient manner.

With underfloor heating, the systems can be installed in new properties or those undergoing refurbishment, extensions to homes would be ideal and so would conservatories making them a year round proposition. You can easily combine an existing system such as radiators, an example would be the ground floor being heated by an underfloor system whilst the 1st floor is heated using a wet radiator system, or radiators can be fitted in the bathroom and lavatory in homes where the main system is underfloor heating.

Why people prefer underfloor heating

Ask anyone who has installed underfloor heating and they will tell you that it has great advantages over traditional wall mounted radiators. Many will claim with justification that it is cheaper to run than a conventional system, although this may depend upon the type of home into which underfloor heating is being installed. Usually underfloor heating using hot water in pipes beneath the floor is run at a lower temperature than that in a radiator.

Wall mounted radiators act as convectors to heat the air, with underfloor heating, the whole floor area acts as an emitter for radiated heat, the result is that the same level of comfort is achieved by underfloor heating at about 2°C lower than in a room heated with conventional radiators. With no need for wall mounted radiators, there is less restriction on placing furniture in the room also less ‘dust traps’ so the rooms are easier to keep dust free. Another massive plus with underfloor heating in kitchens and bathrooms is the fact that, say in wet rooms, the floor will dry quicker.

The advantages of underfloor heating

Underfloor heating heats from the floor upwards which allows an even distribution of heat maximising comfort levels. Conventional systems using radiators only offer localised heat and normally need to run at a much higher temperature. Heat from radiators rises directly to ceiling level leaving the temperature at floor level much lower.  Many find that a concentration of heat at head height can cause discomfort.

Control of the heat is simple with the smallest temperature difference between the floor and the air above means the system is easy to regulate. With individual room control being a common feature of underfloor heating systems, you can individually adjust temperature settings in each room of the house. Better still, by installing underfloor heating you can save hard earned money as this can result in a 15-40% energy saving over traditional heating methods.

Important health benefits can be seen with the use of underfloor heating particularly asthma sufferers, the system helps to reduce the number of dust mites in your home because moisture content levels are too low.

About underfloor heating

Underfloor heating is widely used in northern Europe and has in recent years become quite popular in the UK, both for new builds and updating existing property.  Underfloor heating is very efficient as the floor itself becomes the heat emitter and the heating of the room is from the floor up, unlike radiators in a normal central heating system where the emitters are mounted on the wall and through convection the room is effectively heated from the ceiling downwards.

There are two forms of underfloor heating commonly in use; they are almost identical apart from obviously, that one uses electric heating cable while the other circulated heated water through a pipe. Water based systems use water heated at a lower temperature than in conventional radiators, which makes it ideal for use with a high efficiency condensing boilers; the lower operating temperature also makes it more suitable for use with heat pumps or solar water heaters.

Electric underfloor heating uses cables embedded into a screed or for existing properties this can now be achieved by use of a heating mats, cable kits, or carbon heating films. Running costs for electric underfloor heating is not expensive and in the case of a conservatory for example will be more efficient than radiators due to the fact that you are using the whole floor as a low temperature radiant room heater.

Underfloor heating how does it work and where can I put it?

The first thing that we have to say is that underfloor heating, in common with any form of heating not work efficiently in poorly insulated homes, where the heat generated will simply escape. Check with your installer about ways to ensure that you keep heat loss to the minimum.

Underfloor heating provides the warmth to a room from the floor up rather than heating the ceiling space first which is normal with conventional radiators. Essentially, all systems work in the same way, a heating element warms a heat spreading device laid under the floor to achieve even warmth across it. The heat can be supplied to that element either by warm water or by electricity, hence the two main types of underfloor heating system, the wet system or electric element.

Underfloor heating is ideal for any location, but it is considered the perfect solution for bathrooms, particularly those with cold stone floors, conservatories and extensions, and a blessing in the kitchen area where a person can be standing for longer periods.

Insulating your underfloor heating

Rightly your underfloor heating engineer with have adequately insulated the surface below the heating elements of your heating system, whether this be electric or water underfloor heating so do not insulate the top! If the underfloor heating is in a conservatory, kitchen or bathroom, it will in all probability be tiled so this will not present a problem.  If however the cables or pipes are within a concrete slab, you may rightly wish to either carpet or cover this with a wood laminate and this is where you must choose your floor covering carefully.

A thick carpet for example may have the effect of insulating your room from the very thing that’s trying to heat it and when choosing your carpet you should check that your choice of floor covering is compatible with underfloor heating. Carpeting a floor that has underfloor heating is a bit like putting a duvet cover on a radiator and is bound to have an effect. As a rule of thumb, the thicker the combination of underlay and carpet then the greater the insulating effect. It will still heat the room of course, but it will take longer using more precious fuel.

Underfloor heating mats

Underfloor heating mats are the ideal answer to bathroom, kitchen or conservatory floor particularly if these are tiled. The underfloor heating mat can be used for anything from simply taking the chill of cold tiles in a bathroom or kitchen, right through to a complete home heating system. Surprising to many the running cost using underfloor heating mats is low, the thermostatic control in each room means that you only use just enough energy to maintain your desired room temperature.

The heating mat is designed to be installed directly below tiles and stone flooring, cable mats are the perfect solution for larger square or rectangular rooms. The mats are available in two different outputs, 150watts per square metre for internal rooms and 200 watts per square metre for conservatories and other areas that may suffer high heat loss. A fully programmable digital thermostat included with every installation.

Electric Underfloor heating costs

When the systems are used in a well-insulated building the running costs of underfloor heating are usually very low, the thermostatic control in each room means that you only use just enough energy to maintain your desired room temperature. Taking a conservatory with an insulated floor as an example, electric underfloor heating will be more efficient than radiators due to the fact that you are using the whole floor as a low temperature radiant room heater.

Electric underfloor heating is also more efficient than radiators as well as other convected heat. The electric system does not require periodic maintenance but importantly 100% of the electrical energy is turned into heat energy, rather than being lost as exhaust gases or transfer trough pipes to radiators. . Electric underfloor heating stands out as an excellent choice, particularly where there is no mains gas supply, then you have a choice of oil or LPG.

Installing heating cables to a screed

In screed systems provide a highly efficient electric underfloor heating solution for new builds or areas where a new floor is being fitted, a good example of this would be where a new conservatory is being constructed. Heating cables are installed directly above foil faced insulation below a 65mm screed.

When choosing a heating system which uses in screed cables, you would take into consideration the aspect of the room, extension being built, or conservatory as this can have an effect upon the overall warmth of the area. Design parameters require output of between 130w/m² and 200w/m² dependent upon room where this is being installed or the construction type.

Naturally your electrician would ensure that all underfloor heating installations must be connected via an RCD (earth trip) protected circuit, this could be very important in a conservatory where water from open doors and windows is more likely than in other rooms. Thermostatic control is vital in order to keep the room at a pleasant temperature and ensure that you’re in screed underfloor heating remains the most cost effective choice of heating for your new room, which is a choice that you will never regret.

Underfloor heating to a tiled floor finish on to timber/plywood base

All timber floors whether floor boards, chipboard or plywood must be assessed to confirm structural integrity and suitability for tiling prior to installation of electric underfloor heating. Advice in this matter should be sought from a suitable flooring specialist, however as a rule of thumb, good quality plywood such as marine ply of a thickness in the region of 10mm is regarded as being the minimum to ensure a satisfactory finish.

Floor boards will always require provision of insulated tile backing boards before heating can be installed. Mats and cables can be fitted directly on to ply-wood and moisture proof chipboard, providing that the floor is treated with a suitable priming solution. The heat output required will depend upon the room but this would vary from 100w/m² to 150w/m² dependent on floor base specification.

For both of the above installations, under tile cables offer a far more flexible heating solution in terms of area coverage and heat output. However, for rooms of a regular shape, underfloor tile mats provide a quick solution for these areas. It is important to note that your electrician must ensure that all underfloor heating installations must be connected via an RCD (earth trip) protected circuit. All underfloor heating applications in bathrooms, wet rooms and shower rooms must use heating cables with an earth screen.
