Underfloor Heating & Cooling

Main Heating

Do you still have complete freedom to choose your source of heating? Then choose floor heating as your only source of heat. Radiators or other types of heating are unnecessary. Your floor already provides the required heating capacity and with the right adjustment of your clock thermostat, every room will have precisely the desired temperature at any given moment.

Additional Heating

Is your proposed floor finish to be natural stone or quarry tiles? If you only have central heating, the cold stones may make you feel that the entire room is cold. If you use additional heating, you will be able to enjoy a warm floor temperature too.

Electric Floor Heating

Do you want to install a new tiled floor on top of an existing floor? Then consider Electrotherm. These special, extremely thin electrical heating mats allow you much more scope in smaller rooms, such as bathrooms and kitchens. Electrotherm is easy to install and can be installed directly under the tiles.

Thermo-Floor Electrotherm mat is an electric floor heating system designed to be inserted into the adhesive layer under a tiled or ceramic floor. It is particularly suited to smaller extensions, bathrooms, conservatories and kitchens. The mats are easy to install, only 4mm thick and ideal for retro-fit.

As the mats are laid with the floor finish they are sold on a "supply only" basis. Full installation instructions are included with each shipment and our after sales care will always be happy to advise if you encounter problems.

The Principle of Underfloor/Wall Cooling

With floor / wall heating the temperature of the surrounding surfaces is raised resulting in the most comfortable way of heating we know at this moment, namely, radiant heat.

With floor / wall cooling this principle is reversed. Cooled water flows though WTH underfloor heating tube which reduces the temperature of the surrounding surfaces creating a comfortable inner climate without the disadvantages that air cooling systems have, such as draughts and air pollution and expensive ducting. An additional advantage of floor / wall cooling is that the external construction of the building accumulates less warmth, reducing the heat built up.

Design

When designing a system for floor and wall cooling one must take into account the following.

One aspect of floor / wall cooling to consider is the condensation of moisture on cooled surfaces. At high relative humidity the cooling capacity of the system is limited to this “dew point”.

A “dew point” sensor reduces the risk of condensation. This control also ensures that the cooling capacity is greater when relative humidity is lower.

In spaces where high cooling capacities are necessary (e.g. poorly insulated properties) the floor / wall cooling may be insufficient. In these circumstances the floor / wall cooling must be considered to be “top-cooling” - the reduction of the room temperature by a number of degrees, but not necessarily sufficient to achieve the desired ambient.

When designing a floor / wall cooling system you must ensure that direct sun light though glass areas is prevented as much as possible. In the summer the radiant heat of solar rays though glass is mainly responsible for increasing the temperature in buildings. This then increases the required cooling capacity. The surface heat of the solar ray is removed directly by the cooling effect and as a result no heat is accumulated in the floor and walls. Solar rays that are falling directly onto a cooled floor / wall can increase the cooling demand up to 100 to 150 W/m². This will mean the cooling system is running at its maximum, hence the importance of shielding the sun from entering the building.

When a good quality dew point control is used there is no need for the manifolds to be insulated.
