How to Calculate Underfloor Heating

Written by cameron easey | 13/05/2017

Underfloor heating uses mats that provide heat that radiates through the floor. Many systems come with a timer, which is used to preheat the floor at a specific time. Typically, a heating system of this type is installed under a tile floor. This means that you will need to calculate the amount or space or area that you want to heat before installing the flooring.

Decide in which room or rooms in your home you want to use underfloor heating. Two common rooms for underfloor heat are the kitchen and bathroom.

Measure the dimensions of the room with a tape measure. Find the width and length and write down the measurements.

Reduce the size of the room to the area which is used the most. Underfloor heating systems should cover about 65 to 80 per cent of the room.

Determine where the thermostat will be located on the wall. A wall that has an unused electrical socket will provide the wiring needed for the thermostat.
