Vent Axia electric underfloor heating kits contain both our bluethermal heating mats and thermostat controller.
We stock our kits to make the product selection as simple possible for you, Our range of electric underfloor heating mats are available in both 100 and 150wm2.
The 100 W/m² mat can be installed on any type of levelled and stable sub floor, and is recommended to be used under parquet or other wooden floor coverings.
Our 150 W/m² must be installed on a non-combustible levelled and stable sub floor and is suitable for use with tiled or ceramic flooring.
You will find our simple measuring up guide below and our kits can be selected by the total heated area in the first column in the tables at the bottom of this page.

How to Measure up
Step 1. - Calculating Total Area
Measure the length and width of your room, In this example the bathroom is 3m x 4m giving a total of 12m2 .
Total Area
| Width |
3m |
| Length |
4m |
| Total Area |
12m2 |
Step 2. - Calculating Unheated Areas
When installing underfloor heating you have to ensure that the heat can escape into the room. When calculating the heated area we deduct any fixed furniture such as kitchen cupboards. In this example we will deduct the bath, basin, shower tray toilet and cupboard, the unheated area.
Total Unheated Area
| Bath |
1.4m2 |
| Sink and toilet |
1m2 |
| Shower and Cupboard |
1.7m |
| Total Unheated Area |
4.1m2 |
Step 3. - Calculating heated Areas
The heated area is calculated by taking the unheated areas away
from the total area. In this case:
Total heated Area
| Total Area |
12m2 |
| Total Unheated Area |
4.1m2 |
| Total Heated Area |
7.9m2 |
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 it's 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.
