Installing your system

We offer a full installation service if

required. A comprehensive installation

guide is provided with our mats. Copies 

are available on request. 

Will it help to have insulation below the

heating mat?

Insulation will make the property more

thermally efficient and the heating more

effective. Tile backer insulation boards are

available in thicknesses of as little as 10mm,

which are ideal for floor insulation.

What are the running costs?

Basically, a kilowatt of electricity (1000

watts) costs about 7p per hour at peak 

rate (consult your electricity board for

accurate prices). 

Our underfloor heating mats are rated

between 160 watts and 200 watts per

square metre. Detailed below are

calculations based on the worst case

scenario, the floor having a concrete

subfloor without insulation (with insulation

or tile backer boards running costs can be

cut by as much as 50%).

• 1m

2

of 160w costs approx. 1.12 

pence/hour

• 1m

2

of 200w costs approx. 1.40  

pence/hour

The programmable thermostat allows you

to set the temperature of the floor for

comfort and economy. The heating can also

be programmed to switch on or off so the

floor is warm just when you need it!

What happens if the system goes wrong?

Once the underfloor heating is installed 

and the floor covering is laid on top, the

heating mat will not malfunction and is

covered by our 10 year guarantee. If the

fault is diagnosed once the floor is down,

it can be traced down to beneath 1 or 2

tiles. We have never had to take up a

complete floor.

Step 1

Plan where to

install your heating mat.

Step 2 - 

Cut the fabric

backing and bend the

heating mat to fit the

room.

Step 3 - 

Stick your mat

to the prepared subfloor

and apply a thin layer of

adhesive over the mats.

Always use flexible

adhesive and grout.

Step 4 - 

Apply the tile

adhesive and tile. To allow the

adhesive to dry naturally, the

heating systems cannot be

turned on for two weeks after

installation of the floor tiles.
