Electric underfloor heating thermostat

Precise and accurate temperature control is important to fully achieve the advantages of under floor heating without using more
electric energy than necessary. Heating cables in combination with an accurate thermostat are one of the most energy efficient heating systems one can have in a modern building.

The design of the thermostat is unique. Every detail has been carefully designed, paying special attention to aesthetic appearance, user-friendliness and quality, as required and demanded by both consumers and professional installers.

How to Measure up

Step 1. - Calculating Total Area

Measure the full length and full width of your room.

In this example the bathroom is 3m x 4m giving a total of 12m².

Step 2. - Calculating Unheated Areas

When installing underfloor heating you must ensure that the released heat can escape into the room.

When calculating the unheated area, you must total the area of any fixed furniture such as kitchen units.

In this example the bath, basin, shower tray, toilet and cupboard are added together leaving you with the total unheated area of the room.

Step 3. - Calculating heated Areas

The heated area is calculated by taking the unheated areas away from the total area.

See example below:

Step 4. - Product Selection and Sizing

Mats are selected at 90% of the total heated area allowing room for the required spacing around the perimeter of the room and between the mat on its return.

In this example the area is 7.1m² for mat installation, rounded down to the nearest kit size of 7m².

Insulation boards - 110% of the total heated area requirement due to the wastage when cutting.
