Installation of Large Areas Using a Combination of 2 Cablewarm®200 Heating Mats

Illustrated below is a 19m² conservatory requiring a primary heating source. High output 200W/m2 Cablewarm®200 conservatory heating mats have been selected for the installation.

After making an adjustment for the conservatory corners of 1m2, a 10% standard perimeter allowance has been deducted to give a total heated area of 17.1m2: from the Cablewarm®200 conservatory heating mat range, the FHMC3400 (17m²) has been selected - a combination of two Cablewarm®200 heating mats.

Using the larger of the two heating mats, run this out from the termination point to the opposite end of the room: check the remaining floor area will accommodate the additional heating mat. Lay the additional heating mat and where necessary cut the mat backing to allow the floor heating cable to be run around fixed units, odd shapes, corners and previously laid matting. Remember, never overlap the heating mats as this will cause localised overheating, leading to eventual failure and invalidation of the manufacturer’s guarantee.

The thermostat sensor must be positioned centrally between the heating cable loops – see the Thermostat and Floor Sensor section below.
