How to Measure Up
Electric Underfloor Heating
When installing electric underfloor heating systems, it is vital that you make sure your calculations are correct before ordering, as cables cannot be cut during installation and we do not refund items which have been cut or damaged.
We recommend that when you take your measurements, you do so in metric (metres) and that you have these double checked before placing your order.
Please see below an example of how to measure your underfloor heating:
Calculating the required mat size
First you will need to calculate the total room area (20m²). You will then need to deduct the fixed furniture in the room, as below:
- Island (1.44m²)
- Unit 1 (1.2m²)
- Unit 2 (2.4m²)
- Unit 3 (1.2m²)
This then leaves a total floor area of 13.76m².
You must then allow for a 50-100mm border between the furniture/walls and heating mat which will leave roughly 85-90% coverage. Calculate this area:
13.76m² x 0.9 (90%) = 12.38m².
Then round down to the nearest mat size within the range which would be a 12m² heating mat in this example.
For mat sizes above 12m², a combination of heating mats can be used to fill the available area.
Multiple mats can be used on a single thermostat however the maximum load of the thermostat needs to be taken into consideration as a contactor may be required.

Wet Underfloor Heating
We appreciate that sizing up wet underfloor heating is a slightly more complex job than for electric.
As such, please give us the details of your project below and our technical advice team will contact you within 1 working day to help you size it all up and choose the correct pack and system.
