HOW TO MEASURE
Measuring up for your underfloor heating system is very straight forward, all you need to do is follow our 4 step guide to calculate the required coverage you will need for any of our underfloor heating mat systems
STEP 1: MEASURING THE SIZE OF YOUR ROOM
Measure the length and width of your room. Add the room length & width into the boxes provided, multiply them together, and place the calculation in the total room size box.
STEP 2: MEASURING ALL AREAS WHICH WILL BE UNHEATED
It is not necessary to heat under any permanent footprints such as a shower, toilet, kitchen island and units etc., so we need to calculate any permanent footprints you may have in your room. For each permanent footprint add the length and width to the boxes provided, then multiply them together to get the total m2 for each footprint. Once you have calculated all your permanent footprints add all the sizes together and place your calculation in the total permanent footprint box.
NB: If you have more than 4 permanent footprints , apply the same calculations and add them to the total footprints.
STEP 3: CALCULATING THE TOTAL HEATED AREA
From Step 1 & Step 2 calculations, add the total room size (m2) and the total permanent footprint (m2) into the boxes provided. Subtract the total permanent footprint from the total room size and add your calculation to the box “Total Free Floor Area” – this is your Free Floor Area for heating.
STEP 4: FINALLY, CALCULATE YOUR UNDERFLOOR HEATING MAT SIZE IN m2
In order to obtain the correct mat size for your room and to allow for fitting, the total free floor area calculated in Step 3 must be reduced by 10%. When fitting underfloor heating mats it is better to be smaller rather than too large because the heating cable cannot be cut or shortened.
The total mat size needed, as calculated above, is then normally rounded down to the nearest mat size. For example, 10.6m2 will round down to 10m2, 17.4m2 will be 17m2, 7.4m2 will be 7m2 and so on…
