There are primarily two types of systems for underfloor heating. Both heat your floor evenly from the ground up, but there are some key differences
Electric Underfloor Heating Systems
Electric Underfloor Heating (dry heating) systems employ electric wires or mats which are installed beneath your flooring. The system is usually placed on the top layer of floor insulation to make sure that the heat rises, rather than directed downwards. The wires or mats are then connected to the mains supply.
According to Which? Around 65% of people prefer electric systems. They are generally easier to install than water-based systems and are ideal for fitting in existing properties. Generally, they are less expensive to install than the water system, but running costs are slightly higher than the aforementioned system.
Water Underfloor Heating (Wet ) Systems
With a water-based system, pipes are laid beneath your flooring and connect to your boiler. Warm water is circulated and heats the area. The water-based system is ideal for larger areas, but is more complex to install, making it more expensive than the electric system. The benefit comes in the form of running costs which are generally more economical.
