What is Water Underfloor Heating

Water underfloor heating, commonly referred to as hydronic or wet underfloor heating, is a modern way to heat homes using radiant heat technology. Wet underfloor heating systems work by circulating warm water through pipes installed beneath the floor. This innovative technology offers consistent and efficient heating while bringing a range of benefits to residential and commercial spaces.

Why install Wet Underfloor Heating?


Removing radiators from a room gives any budding interior decorator much more freedom – every wall is free to use for furniture, art etc. and you no longer have to worry about positioning furniture too close to radiators.


The control options for wet underfloor heating systems offer precise temperature management and zoning capabilities. These controls allow personalized heating schedules, adapting to individual preferences and daily routines. Integrating smart technology enables remote access, providing convenience and energy-saving benefits. With consistent, even heat distribution, these systems underfloor heating an efficient and adaptable solution for modern homes.

For example, you may wish heat the bedrooms, bathroom and kitchen in the morning but not use the lounge or dining room. By carefully setting up your system to suit your individual needs you can add to the efficiency and further reduce running costs.


Water underfloor heating is a very comfortable form of heating and heats every room evenly and from the ground up. The first thing you will notice when you have underfloor heating is that you will never have cold feet ever again. Walk about in your bare feet throughout the year in perfect comfort.

With traditional radiator heating systems, the heat will rise and heat the ceiling first and eventually the convection currents will move the heat around the room and heat the entire room. It will always be cooler closer to the floor and warmer nearer the ceiling. The complete opposite of what you want sitting in your lounge on a cold winter’s night.


Wet underfloor heating is a very efficient form of heating. Firstly, the heat is distributed where it is most useful, not being wasted heating ceiling space. Secondly, underfloor heating runs at much lower temperatures than radiators. This means that boilers can be run at lower temperatures and as a result can run far longer in condensing mode making the operation much more efficient.

This lower running temperature also makes wet underfloor heating the perfect partner for modern green heating systems like air source or ground source heat pumps.

Estimates of fuel savings vary from 15% to 40%. Find out more ways to make your home energy efficient.

What does a Wet Underfloor Heating System cost?

Water or Wet underfloor heating is on the whole more energy efficient than a standard radiator, and is therefore less expensive to run. As heat is distributed in a more even fashion, the water temperature of the system can be much lower.

Of course, this will all depend on the size of your home, type of boiler and how energy efficient your home is.

What sort of build is suitable for a Wet Underfloor Heating System?

Water underfloor heating is suitable for both new builds and where a renovation is taking place. It is ideal for new builds as floor levels have not yet been established. Wet underfloor heating can also be installed as a retrofit.

How does a Water Underfloor Heating System actually work?

An underfloor heating manifold is connected to a heat source such as a a boiler or air source or ground-source heat pump. Wet underfloor heating pipes are run from this manifold under the floor of every room and warm water is circulated through these pipes to heat up the floor.

A thermostat (there can be more than one depending on the number of zones) is fitted to your system so you can control the room temperature. Floor temperature can also be controlled which is important for some timber floors with maximum temperatures.

What type of boiler do I need for a Wet Underfloor Heating System?

Generally, waters systems will work with most boiler types – condensing, vented or wood-fired for example. They will also work well with heat-pumps plus these generally run at a lower temperature compared to standard boilers.
