What is Wet Underfloor Heating?

Wet Underfloor heating system, also known as a water heating system, warms up the room through a series of pipes. The pipes are connected to the heating source through the manifold. Water is heated up via the heat source and spreads the warmth throughout the room. The hot water underfloor heating system is becoming increasingly popular among UK households owing to its even temperature, low running cost, and higher reliability and efficiency.

How Do Water Underfloor Heating Systems Work?

Water underfloor heating is a system that uses hot water to heat the floor of a room. It works by circulating hot water through a network of pipes that are embedded in the floor. The pipes are typically made of polyethylene or polypropylene and are installed with a spacing of 10-15 centimeters each. The hot water is heated by a boiler, a heat pump, or another source of heat. However, to connect the underfloor heating system to the heating source, such as a heat pump or boiler, you need a manifold.

What is an Underfloor Heating Manifold?

A manifold is a system that connects the underfloor water pipes with the heating source to work together. It consists of two rows of taps, which allow the warm water to circulate from the heating source through the underfloor circuits. The number of pipes and the complexity of the manifold depend on the system size. The larger the system is, the higher the number of pipes and the more complex the manifold will be.

What is the Required Temperature for Water Underfloor Heating?

The underfloor heating wet system usually runs at a comparatively lower temperature compared to radiators or other types of heating systems. It operates at as low as 35°C compared to 55-60°C. However, the actual temperature required for a hot water underfloor heating system depends on the type of flooring used to cover it. The harder it is for the heat to get through the floor, the higher the water temperature will be. As the underfloor heating wet system is installed with a mixing valve, you can easily adjust the water temperature as per your needs and requirements.

How Much Does Underfloor Heating Wet System Cost?

The underfloor heating water system is more expensive than the electric underfloor heating system, but the running cost of the underfloor heating wet system is significantly lower compared to other types of underfloor heating systems. However, there are still many factors that can affect the overall cost of a hot water underfloor heating system in the UK, including the size to be heated, type of flooring, and labor costs in your area. The underfloor heating wet system is also more efficient than radiators, around 24% more efficient, making the system less expensive in the long run.

Where Can Water Underfloor Heating Be Installed?

The water underfloor heating system can be installed in any space if you have the proper water pipe infrastructure and a suitable heat source. However, the most appropriate spaces for installing the underfloor heating wet system are the kitchen, followed by the living room.

Unlike electric systems, underfloor heating water systems require more space, but they work perfectly in areas where the floor is properly prepared and insulated. Installing a hot water underfloor heating system in a new building is relatively easy, as adjustments can be considered from the start.

Therefore, the system is typically installed in new builds. However, it can still be installed in your existing home, depending on the types of flooring.

Does Underfloor Heating Need a Special Type of Boiler?

You don’t need to buy a special type of boiler for a underfloor heating water system, as the underfloor heating water system is compatible with all types of boilers typically used in homes.
