Underfloor Heating

Underfloor heating is a great way to keep your home warm. It distributes heat evenly around each room, is cosy underfoot and it frees your walls from radiators. Economical, 100% efficient and safe.

Why Choose Underfloor Heating?

Underfloor heating dates back to ancient times. It is a great way to keep your home warm. It distributes heat evenly around each room, is cosy underfoot, and frees your walls from radiators. 

Better still, underfloor heating is generally more efficient than old radiator systems, operating at lower temperatures which can make it more cost-effective. 

Plus, underfloor heating can now be installed with the vast majority of floor surfaces including vinyl, engineered wood, laminate and even carpet.

How does Electric Underfloor Heating Work?

Underfloor heating can be a dry or wet system. If you are interested in a 'wet' system, please see our Electric Boilers and Heat Pump page. 

Electric underfloor heating works by radiating heat from a series of cables or panels installed beneath or within your flooring, essentially turning it into a cosy, giant radiator. A room thermostat controls the desired temperature and once this rises above the ambient temperature of the air, the heat spreads throughout the room at an even, comfortable level with no unpleasant hot cold spots.

Is Underfloor Heating Difficult to Install?

Electric systems come in a variety of options some of which are thin and simple to fit, so they can be a lot less hassle to install in an existing room than a wet underfloor heating system, which requires some space for pipework and could involve the floor being lifted.

For this reason, electric underfloor heating is a great option for retro-fitting or even for adding to a single room such as a bathroom or a conservatory.

If you are interested in heating your whole house or just a single room, ask our Sales Team for advice, they'll be happy to help you find the right solution for you. 

Is Underfloor Heating a Sustainable Heating System?

Whilst electric underfloor heating is not normally considered low carbon heating, in Guernsey the majority of our electricity is imported from sustainable sources in France so any electric heating is already a lower carbon option than fossil fuel systems, 

What are the Benefits?


Wet System

A wet underfloor heating system requires a fuel boiler to heat water up to a defined temperature and then circulate it through a manifold to each room of your property that requires heating. Electric boilers can facilitate this system in the form of a Flow Boiler, a Combination boiler or a Heat Pump. Each heating zone in your property should be fitted with its own thermostat which controls the air temperature of that room.

Each thermostat links to the wet system’s manifold and to one, or more, of the valves on the manifold. This valve will open to let hot water into a specific room’s system to provide heat, if required. This heat is generated from the central heating boiler. When the thermostat is satisfied the room temperature is achieved, the valve on the manifold will close and the central heating boiler will switch off.

Further control can be added to the system by adding a programmer to the electric central heating boiler. The programmer can be set so that the central heating boiler only operates in the low rate of the electricity tariff. Furthermore, the programmer can allow you to set ideal times of day that central heating is needed so to ensure the heating isn’t left on when nobody is home, all of which helps save on electric heating bills.

Dry System

An electric dry heating system involves electric cables being laid under a room’s flooring which are then attached to a room thermostat. If the thermostat is asked to achieve a specific temperature and the room is currently colder than required, the underfloor cable creates heat which transfers through the floor. Once the room thermostat is satisfied the desired temperature is achieved, the heating turns itself off.

Each room should have its own underfloor heating cable attached to a thermostat. Furthermore, the room thermostat can be upgraded to a programmable thermostat which allows each room to have individual time settings that the heating will be turned on and off. These times can then be set to work inside the low rate hours of your electricity tariff which helps save on electric heating bills.
