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.
This then leaves a total floor area of 13.76m².
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.
