Water Underfloor Heating Systems

Water, also called wet or hydronic underfloor heating systems are a popular choice for extensions and new-build construction projects. These systems use water for heating, so it can be linked to virtually any heat source from a standard boiler to newer sustainable technologies, such as solar thermal energy or heat pumps.

Installation

Water underfloor heating is usually installed within the subfloor construction of a building. Before starting the installation make sure to read the installation manual and follow it every step of the way. The area must be dry and the insulation must conform to building regulations or practice and again, laid as per manufacturer’s instructions.

Wet System Kit

If you are looking for an easy and quick installation of a wet system, Warmup also offers a water underfloor heating kit. The HydroPack System allows for a fast installation of a wet underfloor heating system containing everything you need to install the system in hours.

What Is the Cost of a Water System?

Water underfloor heating is a highly cost-efficient heating system to run as it uses much less energy than a central heating system. Wet underfloor heating emits enough energy to bring your room to your comfort temperature at flow temperatures of 30-40 degrees. This is significantly less than the temperatures required by conventional radiators to bring your room to comfort temperature (60-70 degrees). This is due to the fact that water underfloor heating systems spread the heat evenly across the floor surface and emit radiant heating through the objects of the room.

Running Costs

Water systems are particularly popular in energy efficient new build houses. You can calculate the running cost per m2 of your wet underfloor heating system here.

Water Underfloor Heating FAQs

How much does water underfloor heating cost to run?

The running cost of water underfloor heating depends on the area size, insulation levels, and heat source efficiency. It is generally more economical than traditional heating due to lower operating temperatures and even heat distribution. High-quality underfloor heating insulation is critical for ensuring an energy-efficient solution and saving on energy bills. For tips, read our blog on How to Reduce Heat Loss in Your Home. For a precise estimate, use our Running Costs Calculator. 


How much does water underfloor heating cost to buy?

The cost of water underfloor heating varies depending on the size of the area, the type of installation, and the specific system chosen. Generally, the initial installation cost is higher than electric systems. For example, a complete Warmup water underfloor heating system for a small bathroom, including pipes, insulation, and an accompanying thermostat, can start at around £500 + VAT.
