What You Need to Know when Choosing the Right Floor Heating for Your Home

Floor heating is a cryogenic system. This means that heat is transferred into the room through the large floor area with a relatively low temperature. A surface temperature of 23-24C on the floor is enough to get comfortable 18-20C of head elevation. The opposite is the high temperature, where small areas (e.g. radiators) with a relatively high temperature heat transfer.

There are many benefits of radiant floor heating. Most think it is pleasant to walk on a heated floor and especially in the bathroom as it dries the floor quickly. A warm floor is a dry floor and does not constitute a breeding ground for the growth of mites and other allergy-causing organisms.

In addition, we can often reduce the heating of the room temperature a few degrees without freezing, thereby saving energy.

Under floor heating reduces the cost

Correctly sized heating in a sealed and well insulated building normally means lower heating costs than e.g. radiator systems. The reduced temperature with improved thermal comfort can mean substantial savings. Power requirements may be kept at such low figures of 40W/square meter. One condition is that the house is suitable for under floor heating. Air intakes should not occur during the windows, the flow of fresh air can be arranged in other ways. A concrete floor on the ground should be insulated with at least 100 mm mineral wool or equivalent.

Waterborne or with cables

The most common heating systems today are based either on circulating heated water or by direct electrical heating cables. Waterborne systems are often used for global warming. They require a higher investment cost than the electrical system and are therefore chosen to be ideal for new constructions. They give great choice for an energy source. Oil, wood or gas can be used.

Today, there are also thinner systems suitable for renovation. Electrical systems are suitable mostly for renovation and for small areas, such as the bathroom. Thanks to its good dependability and ease of control, direct electric heating in floor heating will certainly become an increasingly common option also related to global warming. Systems that run directly on the networks with 230 volts, is tested and suitable for global warming. There are also other systems based on so-called extra low voltage, i.e. below 50 volts. These require that the voltage is transformed down and they are normally used only for comfort heating.

Best with tiles and stone floors

A solution for low-temperature floor heating which will work well is to heat the led from the pipe or cable so it produces heat out to out to floor. The temperature should be as uniform as possible over the surface. The best conductivity is hard and heavy material tiles and natural stone. Porous materials such as wood and textiles have a low thermal conductivity and must be supplemented to the underside of plates or metal that conducts heat laterally.
