An overview of commonly used underfloor heating types.
Underfloor Heating (UFH) is a form of heating used to provide heat to a property from below the final floor finish. There are two main types of UFH: Electric and Wet.
Why Underfloor Heating Works Slower Than Other Heating Systems
Underfloor heating systems work at lower temperatures than standard radiators. This means they take longer to heat up, but once the system is up to temperature, it’s very efficient at maintaining that heat.
Electric Underfloor Heating
Electric UFH systems are used solely for heating purposes. They are made up of flexible, non-corrosive heating elements, including cables, preformed cable mats, carbon films, and bronze mesh. These elements are installed beneath the floor and heat up when electricity is passed through them.
Installation and Commissioning
Electric UFH uses fewer components than Wet UFH, making it simpler to install and commission. The heating elements are laid out on the subfloor, connected to the thermostat and power supply, and then covered with the final floor finish.
Leveraging Time of Use Tariffs
Electric underfloor heating systems can leverage time-of-use tariffs by heating up during off-peak hours when electricity is cheaper. The system can then maintain the heat throughout the day, providing a cost-effective heating solution.
Wet Underfloor Heating
Also known as Hydronic UFH, this type of system can be used for both heating and cooling purposes. It involves circulating a mix of warm water and antifreeze through a network of polyethene-based UFH pipes.
How it Works
The UFH pipes are laid out in a closed-loop system, connected via a central manifold and pump. A heat source such as a boiler, air source heat pump, or solar thermal is used to provide warm water to the UFH pipes.
Benefits of Wet Systems
Wet UFH systems are highly efficient and can be more cost-effective to run than electric systems, especially in larger areas. They can also be integrated with renewable energy sources, making them an environmentally friendly option.
In conclusion, both Electric and Wet UFH systems have their own unique advantages and are suited to different types of properties and requirements. It’s important to consider factors such as the size of the area to be heated, the available power sources, and the specific heating needs when choosing the right UFH system.
