Comfort Heat: Floor Heating FAQs

Thinking about installing underfloor heating? At Comfort Heat, we’re often asked similar questions from homeowners looking for energy-efficient, comfortable, and long-lasting heating solutions.

Below, we’ve answered some of the most common questions about floor heating to help you make an informed decision.

1. Is underfloor heating expensive to run?

The cost of running underfloor heating depends on several factors, including the size of the heated area, the type of system (electric or hydronic), room insulation, and local energy prices.

Generally speaking, underfloor heating systems are highly energy-efficient. They operate at lower temperatures than traditional radiators while still providing a comfortable, consistent warmth. This efficiency can translate into reduced energy usage and lower heating costs.

Electric systems are often more affordable to install but may cost more to run due to electricity prices.

Hydronic systems (water-based) use heated water and can be more economical over the long term, especially for larger spaces or whole-home heating.

For the most accurate estimate, it’s best to consult a heating professional who can assess your specific property and energy setup.

2. Is underfloor heating enough to heat a room?

Yes, underfloor heating can be sufficient to heat a room effectively — provided the space is well insulated and the system is correctly designed.

Underfloor heating delivers even heat distribution across the entire floor, which then radiates upward to warm the whole room. In well-insulated homes, this can completely replace traditional heating systems.

However, in larger rooms, high-ceilinged spaces, or poorly insulated areas, you may need an additional heat source to achieve optimal comfort. A heating specialist can help you determine the best setup for your home.

3. Can I put furniture on top of underfloor heating?

Yes, you can place furniture over underfloor heating — but with some important considerations.

Avoid positioning large, solid items directly on the floor, as they can block heat flow and cause uneven heating. This includes bookcases, wardrobes, or sofas without legs. Ideally, furniture should have air gaps underneath to allow heat to circulate freely.

Be cautious with rugs and mats as well. Thick materials can trap heat, leading to inefficient operation or potential floor damage. Always ensure the heat can dissipate evenly throughout the space. When in doubt, seek advice from your installer or heating professional.

4. What should I do with underfloor heating in summer?

During warmer months, you have a few options for managing your underfloor heating system:

• Switch it off: Simply turn off the system when it’s not needed to save on energy.
• Use for cooling: Some advanced hydronic systems can circulate cool water instead of hot, offering mild cooling in summer.
• Maintain low heat: If your region experiences sudden cold snaps, you can keep the system on a low setting to maintain comfort and protect floors.

Every system is unique, so always refer to your user manual or consult your installer for seasonal maintenance tips.

5. How many years does underfloor heating last?

Underfloor heating systems are built to last. With quality installation and regular maintenance, they typically provide 25–35 years of reliable performance.

At Comfort Heat, we use only the highest-quality materials and technology to ensure our systems deliver long-lasting comfort and efficiency for decades to come.
