Electric underfloor heating
Heating mats or cables are connected to a compatible thermostat. Often suited to individual rooms, renovations and projects where a straightforward, low-build-up installation is important.
ELECTRIC AND WATER SYSTEMS
Underfloor Heating
Comfortable, even room heating starts with the right system for the floor construction and project.
Compare electric and water underfloor heating, understand the main design decisions and find the most useful next step for your room or whole property.
CHOOSE A SYSTEM TYPE
Electric or Water Underfloor Heating?
Both heat the room from the floor, but the installation, controls and most suitable project types differ.
Explore Electric Heating
Water underfloor heating
Warm water circulates through pipework connected to manifolds, controls and a suitable heat source. Often selected for larger areas, new builds and whole-property projects.
SYSTEM DESIGN
Five Decisions Shape the Right System
There is no single best system for every project. These details determine what will work well.
Floor construction
New screed, an existing structural floor and timber joists each require a different installation approach.
Heated floor area
Measure the usable area and exclude fixed units or other permanently obstructed spaces where required.
Heat loss and insulation
The building fabric and room heat loss determine whether the proposed system can meet the heating demand.
Final floor finish
Tiles, engineered wood, laminate, vinyl and carpet each have system and temperature considerations.
Controls and zones
Plan how rooms will be grouped, scheduled and controlled before choosing thermostats or wiring centres.
HOW THE SYSTEM TAKES SHAPE
From Heating Layout to Installed Floor
A designed pipe layout plans the circuits first; the installed system then follows that route across the insulated floor.
Designed around the room layout
A pipe plan accounts for room boundaries, manifold position and the route of each circuit.
Installed before the floor is completed
The heating pipe or cable becomes part of a complete floor build-up selected for the construction.

COMMON QUESTIONS
Underfloor Heating Questions
Common starting points for a new project.
Can underfloor heating be the main heat source?
It can be where the designed output meets the room heat loss. A project-specific heat-loss assessment is the right way to confirm this.
Which system is cheaper to run?
Running cost depends on energy tariffs, heat demand, insulation, controls and how the system is used. Water systems are often considered for larger areas, while electric systems can be practical for individual rooms.
Can I use underfloor heating with my floor finish?
Many finishes are compatible when installed within the floor manufacturer’s temperature and thermal-resistance limits. Check the complete floor build-up before selecting the heating system.
