ProWarm electric underwood heating mats offer a reliable, durable and effective underfloor heating system for laminate floors, engineered and solid wood floors.

The ProWarm under wood heating system has a heat output of 140W/m2. It's an ultra thin electric radiant floor heating solution, designed especially for use under wooden flooring. It's very easy to install and will heat the floor in a uniform manner - with no 'hot spots'.

ProWarm underfloor heating kits contain everything you need to install them, along with detailed installation instructions, all packaged in one box.

ProWarm underwood heating mats are available in the following square metre sizes (please choose from the drop-down box above): 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. The maximum mat size in one piece is 12m2 - anything larger is supplied as multiple mats.

Please ensure all safety guidelines are followed during and after installation.

Please note: Choose a mat size that will cover 90% of your floor area. It's better to order slightly less, as the mats CANNOT be cut to size.

This useful sizing guide will help you select the correct mat size, as well as the accompanying insulation boards! (PDF document)

Please note: ProWarm underwood heating mats must be used with either ProWarm ProFoam or XP-PRO insulation boards. Where possible we recommend using the 10mm thickness XP-PRO boards.

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.
