What to Consider Before Buying Underfloor Heating
You’ll need to think carefully about whether you want to go with electric or water-based underfloor heating. The one you decide to go with will depend on the type of property you’re working on and what your customer wants, too.
1. Electric Underfloor Heating
Fast to install and highly responsive, electric UFH is a popular choice for single-room heating.
Best for:
- Retrofits & renovations
- Bathrooms and kitchens
- Smaller rooms
- Projects where floor height is limited
2. Water Underfloor Heating (Wet Systems)
Water systems use heated water through pipes and are often the most economical long-term solution, especially with heat pumps or energy-efficient boilers.
Best for:
- New-build homes
- Open-plan living spaces
- Whole-home heating
- Energy-efficient properties
Electric underfloor heating is often used in renovation projects and in single rooms. This is because it doesn’t take up too much floor height. Water underfloor heating systems rely on pipes and warm water and are usually found in new-build homes and office spaces, as well as in larger rooms. Water is the better option in these new properties where this is likely to be the main source of heating.
3. Room Size & Layout
Another major consideration is the dimensions of the room that you’ll be heating. This will give you an idea of how much kit you need for the space.
Always measure the area accurately to calculate the correct:
- Cable length or mat size
- Pipe spacing
- Manifold and zone requirements
If you're unsure which system is best, our expert staff across 350 branches are ready to help.
Whichever system you’re thinking of applying, you’re sure to find everything you need online or in one of our UK branches. But if you can’t see what you’re looking for, pop along to your nearest branch and we’ll be able to point you in the right direction.

Underfloor Heating FAQs
What type of underfloor heating is best - electric or water?
The best system depends on your project. Electric underfloor heating is ideal for single rooms and renovations because it has a low floor build-up and is quick to install. Water underfloor heating (wet UFH) is better for new-builds or large areas, offering highly efficient whole-home heating and lower long-term running costs. Both options are available at City Plumbing with full kits and accessories.
How much does underfloor heating cost to install?
The cost of underfloor heating varies based on room size, system type and installation requirements. Electric underfloor heating tends to have lower upfront costs and quicker installation, while water UFH is usually costlier to install but cheaper to run. For accurate pricing, you can browse our range of electric UFH mats, water UFH kits, and accessories online.
Can underfloor heating replace radiators completely?
Yes. Many homeowners use underfloor heating as their primary heating system, especially in modern homes or open-plan spaces. Water UFH is particularly effective for whole-house heating, while electric systems are often used as standalone solutions in bathrooms, kitchens or extensions.
Is underfloor heating energy efficient?
Underfloor heating is one of the most energy-efficient heating systems, because it works at lower temperatures compared with radiators. Water-based systems are especially efficient when paired with a heat pump or modern condensing boiler. This reduced energy usage can help lower heating bills and improve EPC ratings.
What flooring is suitable for underfloor heating?
Most flooring types work with underfloor heating, including tile, stone, engineered wood, laminate and certain carpets. Tile and stone offer the best heat transfer, but manufacturers will specify the maximum tog rating for carpets. Always check floor compatibility before installing your UFH system.
How long does underfloor heating take to warm up?
Electric underfloor heating can heat up within 20–60 minutes, depending on floor type and insulation levels. Water underfloor heating takes longer, usually 1–3 hours, but maintains a steadier, more comfortable heat. Adding insulation boards or foil heaters can significantly speed up warm-up times.
