Wet underfloor heating systems

Water-based underfloor heating systems are commonly installed in ground floors, extensions and full property refurbishments. These systems use warm water circulating through pipes beneath the floor, connected to your boiler or heat pump.

Wet systems are often chosen for:

Ground floor renovations
Kitchen and living space extensions
Open plan layouts
New build properties
Homes upgrading to heat pumps

Electric underfloor heating systems

Electric underfloor heating is often used in smaller areas or where floor height is limited. These systems use electric heating mats or cables installed beneath tiles, laminate or other floor finishes.

Electric systems are commonly installed in:

Bathrooms
En-suites

Underfloor heating repairs

If your underfloor heating isn’t performing properly, we can diagnose and repair the issue. Problems can range from uneven

heat and cold spots to thermostat faults or circulation issues. Common underfloor heating faults we repair include:

Cold areas in the floor : Uneven heating can be caused by air in the system, flow issues, or balancing problems. We identify the cause and restore proper heat distribution.

System not heating up properly : This may be related to controls, pump issues, mixing valves or system pressure. We check the full setup rather than just one component.

Thermostat or control faults : If the system isn’t responding correctly, the issue may be with the thermostat, wiring or zone controls.

Leaks in wet underfloor systems : Although rare, leaks can occur. We carry out careful diagnostics to locate the issue and recommend the correct repair.

Frequently Asked Question

Is underfloor heating suitable for my property?

Most properties can benefit from underfloor heating, whether in new builds or renovations. Wet systems work well with ground floors or where there's sufficient space for pipes, while electric systems are often ideal for upper floors or specific rooms like bathrooms.

How disruptive is the installation process?

Installation does require access to your floor, but our team works efficiently to minimise disruption. For renovations, we coordinate closely with other tradespeople to ensure smooth project management.

Is underfloor heating expensive to run?

When properly designed and installed, underfloor heating is typically more energy-efficient than traditional radiators. The system runs at lower temperatures while providing superior comfort, which often results in reduced heating bills.

Can I control underfloor heating in different rooms separately?

Yes, we install zone controls that allow you to manage temperatures independently in different areas of your home, providing both comfort and energy efficiency.

How long does underfloor heating last?

Quality underfloor heating systems are exceptionally durable. Wet systems typically last 20+ years, while electric systems can last 15+ years with proper installation and maintenance.
