systems you can install electric underfloor  
heating in any size room or location.  
• All our cables are double insulated with  
an internal earth sheathing. The systems  
have been tested and comply with  
It is widely accepted that heating mats are  
superior to loose cable systems, as  
they are much quicker to install and  
have regulated cable widths, so you  
always get a good even heat spread  
with no hot or cold spots.

mat, a programmable Thermostat and an  
RCD (this is not required if you already  
have one on your main electricity board).  
• They are 100% efficient.  
• Fabric backing for better  
installation

Sole Source Heating  
200 watts/m2  
There are three types of underfloor heating  
available. The descriptions below will help  
you choose the most suitable type for your  
particular installation.  
Bathroom Mat – an earth braided system  
for use in all bathrooms including  
‘wet’ areas.  
The Sole Source mat has been designed for  
sole source of heating in conservatories,  
extensions and other areas. At 200 watts/m2  
this mat system is one of the most  
If using underfloor heating for sole source  
heating, it is very important to have  
insulation either under the screed or  
directly below the heating.  
Floor Warming mat – setting the standard  
in underfloor heating. Provides comfortable  
warmth in all Fired Earth tiled floors.

Our thermostats are  
covered by a one year

All you need is the correct heating system,  
a control (timer/thermostat), an RCD and

What electrical/subfloor preparations

Guarantee: 10 years  
What size heating system do I need?  
We recommend a qualified electrician carry  
out all electrical work. The electrician will  
need to provide the correct size spur and  
deep single back boxes for the control and  
Residual Current Device (RCD). An RCD is a  
safety device (circuit breaker) which is  
essential for the validation of the guarantee  
and to comply with IEE guidelines. Prepare  
the sub-floor ready for the final floor finish.  
An RCD is only required if you do not  
already have one on the mains. The wiring  
to the thermostat should be channelled into  
the wall and protected by plastic trunking  
or conduit.  
It is important to make sure that you have  
the correct size heating system. Underfloor  
heating is not laid under permanent  
furniture (kitchen cabinets and sanitary  
ware), just in the free floor space. For  
example, the bathroom in the diagram on  
the left is 4.5m2 of floor area, but the actual  
amount of underfloor heating required is  
only 1.5m2.

robust and available in 300mm widths  
giving a better floor coverage around  
bathroom furniture. It is ultra thin, adding  
only 5mm to the depth of the floor and is
