# Design underfloor heating

The insulating layer is applied and the floating screed ordered, which will enclose the laid floor heating and will be airtight for optimal heat dissipation.
Prior to the planned design of underfloor heating, important factors should be taken into account, so that you can opt for professional work with high heat output and low consumption. The laying distance must be uniform and according to the recommendations of the manufacturer. When planning a heating in the floor, it is advisable to carry out a correct calculation beforehand and to know the formula of the heat emission according to DIN EN 1264.

## Save costs with the correct calculation

The prejudices, in the old building or older house, heating in the floor would not be effective and would cause high costs, are outdated and do not correspond to the truth. Not only in the new building, but also in the old building helps to save floor heating and allows a particularly efficient use of energy. Anyone who operates underfloor heating via a small domestic power plant will achieve high energy efficiency and permanently reduce the cost of heat due to the low flow temperature required for underfloor heating such as underfloor heating. According to DIN, the heat output via underfloor heating is calculated using the following formula: q = 8.92 (tFB, m - ti) 1.1
An exact calculation is not necessary because an estimate usually gives enough information about the necessary size and condition of the underfloor heating, with which the desired room temperature is achieved energy-efficiently.

## The correct design determines the desired heat output

By calculating the demand, it has been shown in which laying distance the heating cables should be laid out. Too long distances would reduce the heat dissipation, but too low distances would cause too much heat in the floor. The heat emission options calculated with the formula are only achieved if the distance does not deviate more than 1 centimeter from the specified DIN standard. However, the formula applies only to isothermal floor coverings that are applied above the underfloor heating. With a very thick and thus heat-impermeable carpet, it is necessary to reduce the distances and to achieve by the smaller installation distance that the desired room temperature is easily achieved. The lower the coefficient of resistance of the visible surface, the closer the installation distances of the underfloor heating are to be generated. When planning and calculating, not only the DIN standard, but also the desired floor covering should be considered and thus allow a perfect calculation of the underfloor heating.

## Observe differences in the heat conduction of surface coverings

Depending on the desired topping, its heat conduction must be considered. A thick carpet, for example, conducts worse than a wooden or natural stone floor. Therefore, it is advisable not only in the new design of a floor heating, but also in the renewal of the top layer, to recalculate the efficiency of underfloor heating and adjust the surface. If a design was originally done under a thick carpet, which is now to be replaced by an elegant wooden floor, the lack of adaptation of the floor heating can result in the fact that the wooden floor deforms and beats due to high heat waves.
Modern underfloor heating, which has been designed to accurately calculate and calculate all the important factors, can save a lot of energy and reduce the cost of heating constantly and permanently.
