There are two main types of underfloor heating: electric and wet, water-based systems.
The right option will depend on the size of the area, the existing floor, the available heat source and whether the installation forms part of a renovation, extension or new-build project.
Electric underfloor heating uses cables or heating mats installed beneath or within the floor.
It is often considered for smaller areas such as:
Electric systems can be relatively straightforward to install, particularly when the existing floor covering is already being replaced. Running costs should be considered carefully, especially when heating larger areas.
Available electric systems may include:
Wet underfloor heating circulates heated water through pipes beneath the floor. The pipework is connected through a manifold to a suitable boiler or heat pump.
Wet systems are commonly considered for:
Wet underfloor heating can operate at lower water temperatures than many traditional radiator systems. Its performance will depend on correct system design, insulation, controls and installation.
Low-temperature heating systems can be well suited to heat pumps, although efficiency depends on the complete system design rather than the floor heating alone.
A properly designed system can provide:
Actual efficiency and running costs depend on the property, insulation, floor construction, controls, energy source and how the system is used.
Underfloor heating can be installed in many existing homes, extensions and new builds. The design must account for heat loss, available floor depth, insulation and the proposed floor finish.
Tiles and stone transfer heat effectively. Suitable engineered wood, laminate, vinyl and carpet may also be used, subject to the flooring manufacturer’s limits.
We will also consider the electrical supply or heat source, heating zones and any effect on doors or finished floor levels.
We inspect the rooms, floor construction and existing heating arrangements and discuss what you want the system to achieve.
We recommend a suitable wet or electric system and provide a quotation explaining the proposed equipment and work.
The system is installed in line with the agreed design and coordinated with relevant flooring or building work.
We test the system and explain how to use the thermostats, controls and heating zones.
ReliaHeat can also investigate faults with existing wet and electric systems.
Problems may include rooms not heating correctly, air or blockages in wet systems, unbalanced flow rates, pump or actuator faults, thermostat problems and electrical issues.
Suitable thermostats and zoning controls can be included within your underfloor heating installation. We can discuss compatible Heatmiser products during your property assessment.
We work with both water-based and electric underfloor heating systems.
You will receive a quotation explaining the recommended system and installation work included.

Neither option is better for every property. Electric systems often suit smaller rooms, while wet systems may be more appropriate for larger areas and whole-home projects.
Running costs depend on the system type, insulation, controls, energy tariff and floor covering. Electric systems can cost more to run across larger areas.
Yes, provided the system is designed to meet the room’s heat requirements. Some homes combine underfloor heating with radiators.
Tiles and stone transfer heat effectively. Suitable engineered wood, laminate, vinyl and carpet may also be used within the manufacturer’s limits.
Yes. Retrofit systems are available, although installation may affect floor height and require the existing floor covering to be removed.
Yes. Wet underfloor heating can work well with heat pumps because it distributes warmth at relatively low water temperatures.
