Good quality product, easy to fit

Had a few heat mats of these guys, and quite a few customers have gone direct now as well. Very good service, the staff are helpful and delivery is quick. This is the only place I get underfloor heating from now

Thank you very much for this really great feedback.

Harmoni SmartFoil 140w/m² Mat - 9.0m², 1260w

Quick to heat up and completely unobtrusive. We love it.

Always available by 'phone to answer any technical questions and when they say they will get back to you they actually do. Fast and free delivery. Refunded me for a faulty item without any quibble and collected the old unit F.O.C. Recommended for anyone thinking of installing underfloor heating.

That is really fantastic to hear, thank you very much for taking the time to leave such great feedback.
