Underfloor Heating Buying Guide

We know that sometimes help is needed when buying a new heating system. We also know the typical questions people ask when they are thinking about getting floor heating, so we have put together this buying guide.

Whether for a whole-house heating system or to heat a single room, our guide explains how floor heating works and how the system can help to stay warm when it gets chilly.

How Does floor Heating Work?

Floor heating works by having a heating wire installed under the floor level. The wire heats up when the system is on, heating the floor surface and providing radiant heat which is evenly distributed and warms the room from the ground up.

With radiant heat, comfort tends to be felt sooner and at a lower temperature. There is minimal air flow, keeping the temperature comfortable and even, everywhere in the room.

Will floor heating be enough to heat a room?

Electric floor heating comes in different heat outputs, with a higher wattage available in order to provide enough heat for high heat loss areas such as conservatories.

The heat output of a floor heating system needs to be greater than the heat loss of the room or area it is heating in order for the system to provide enough heat. So it is important to conduct a heat loss calculation to ensure that the system is suitable. This can be conducted by an architect or a heating engineer and it is important to choose the correct heat output for the floor heating system. If not sure of the heat loss, contact us and we will help to choose the correct system.

It is also advisable to install the system with sufficient insulation, such as insulation boards, which reduce the heat-up time by pushing the heat to the floor level and preventing heat loss to the sub-floor.

Costs Associated with the System

There are a variety of systems available and the floor heating costs depend on the running time, heat output, the size of the heated area and the system type. A thermostat is also needed to control the system, which is sold separately to the heating system. To find out the cost of purchasing a system, request a quote and we will answer with a detailed quote to meet the project requirements.

The running costs are linked to energy prices, room size and height, and running time. Using a smart thermostat, such as the Warmup 4iE Smart WiFi Thermostat can create savings. The 4iE can save on energy usage by suggesting smarter ways to heat a home.

What to look for?


Pay careful attention to the materials the floor heating wire has been made of.


Even though it is unlikely to experience problems with the system after it has been fitted to the floor, it is advisable to check that post-sale support is available if needed.


Even though floor heating is known for its reliability once the system has been installed, it is important to make sure the system is covered with appropriate guarantees.


The systems can be fitted by a competent person, but they can also be installed by a professional installer. All electrical work, including wiring and connecting the thermostat to the heating system, needs to be completed by a certified electrician.
