Water Underfloor Heating is Versatile 

Water systems can be installed virtually anywhere, assuming the floor is well insulated and you have the floor height available to accommodate the system. Low profile overlay systems are best suited for retrofit projects. Why? Because they are so skinny and thin, they prevent floor “stacking” and buildup. That means you simply slip them underneath, or on top of existing floors. Some people dare to go it alone and renovate using wet underfloor heating systems, by doing it themselves; while other opt for the professional advice and support of trades professionals. Here at The Underfloor Heating Company, we offer the 3 main types of Warm Water Underfloor Heating Kits and the best range of accessories, parts and tools – ensuring that you will find the most suitable equipment for any type of domestic or commercial project.

Water Underfloor Heating for Large Spaces, or Concrete

Water underfloor heating generally used for large areas with multiple rooms and full house installations, as it can be more economical and cheaper, compared to electric underfloor heating. Warm water heating can endure being a radiant source of heat slightly longer than an electric system can.

So those gains make sense in adding up over multiple rooms, in the same amount of time – compared to putting in a system for just a one or two rooms, where electric may make more sense for the flooring as the energy savings would likely be equivalent over the same time period.

The best example for warm and wet underfloor heating, is that it works well and strongly with concrete. If you’re building new, it makes far more sense to use a wet underfloor system, and make that part and parcel of your new build as the central heating source.


“Wet underfloor heating means even heat distribution. And, in combination with good insulation, and where ideal, an air source heat pump – it means better sustainability.

For 2020 and beyond, it’s important to have eco credentials for that home, new build or project.”


How To Install Water Underfloor Heating

Opt for trades. Obviously we can’t tell you how to live, and there are thousands of successful DIYers out there. Naturally, we love this industry as a whole and would prefer to say: “let your local qualified trades professional help you with this!” Their unique experiences with multiple installations is a wisdom that’s worth taking advantage of.

In-screed systems are the ‘daddy’ of water underfloor heating. They are perfect for full spec (which is why architects can help advise you with this) for new projects, and therefore water underfloor heating is better for new builds and new extensions.

Joist systems are suitable for a mix of both purposes, new builds and retrofitting, and obviously they are a match made in heaven for suspended floors.
