ProWarm electric underfloor heating mats offer a reliable, durable and effective underfloor heating system that is ideal for use under tiles.

ProWarm 100w underfloor heating mats provide a very economical heating solution for large floor areas. They are NOT suitable as a primary heating source, but are ideal as a secondary source for large tiled areas. They consist of a thin loose wire, which is evenly spaced and attached to a glass fibre mesh. This allows for fast and safe installation. 

ProWarm 100w underfloor heating mats are available in the following square metre sizes : 1M, 1.5M, 2M, 2.5M, 3M, 3.5M, 4M, 4.5M, 5M, 6M, 7M, 8M, 9M, 10M, 11M, 12M, 13M, 14M, 15M, 16M, 17M, 18M, 19M, 20M, 21M, 22M, 23M, 24M, 25M, 26M, 27M, 28M, 29M & 30M. The maximum mat size in one piece is 12m2 - anything larger is supplied as multiple mats.

For use under tiled floors

Sizing Information - ProWarm Electric Underfloor Heating & Insulation Boards

What Size Heating Mat Do I Need?

Step 1. Measure Your Room

When planning on installing your underfloor
heating system, you should first measure
the Total Floor Space of the room.

Measure total room size

Step 2. Find Out Your Free Floor Space

You should then work out the area of Free Floor Space in m2 by accounting for any permanent fixtures or fittings in the room (e.g. bath, toilet).

Calculate size of fixed furniture

Remove 10% from this figure and use this to place your order. You should cover 80- 95% of the free floor space available. Anything less than this will lead to patches of cold spots.

e.g. Conservatory measurement
Total Floor Space = 12m2
Free Floor Space = 10m2 -10%= 9m2

Usable floor space

How Many Insulation Boards Do I Need?

Each ProWarm insulation board is 1200 x 600mm and covers a total area of 0.72m2.
For a free floor space of 9m2, you would need 13 ProWarm insulation boards.
