Underfloor Heating: Your Questions Answered
When it comes to modern, energy-efficient heating solutions, underfloor heating is quickly becoming a go-to option for homeowners across Surrey and beyond. Whether you're building new, renovating, or just fed up with bulky radiators, this heating method offers serious benefits… Serious benefits, but also a lot of questions. Let’s answer them.
How does underfloor heating work?
Underfloor heating works by turning the entire floor into a low-temperature radiator. There are two main types: electric underfloor heating systems, which use cables beneath the floor to generate heat, and wet underfloor heating systems, which circulate warm water through pipes embedded in the floor. Both systems warm the room from the ground up, creating an even, comfortable temperature throughout.
These systems are particularly well suited to tile floors and stone finishes but, can be installed beneath other floor types too.
Is underfloor heating expensive to run?
Not necessarily. While installation can require upfront investment, wet underfloor heating is typically cheaper to run than traditional radiators, especially when combined with a smart thermostat. That’s because it runs at lower temperatures while still managing to heat a room efficiently.
KD Jones Heating Engineers specialise in energy efficiency. We make sure your system is properly designed, installed with the right insulation boards, and paired with the most suitable heat source, whether it’s a gas boiler or air source heat pump.
How much does underfloor heating cost?
Costs can vary depending on the type of system, the size of the room, and your chosen floor finishes. On average:
- Wet systems: £80-£150 per m² (including installation)

Is underfloor heating worthwhile?
Absolutely, especially in spaces like kitchens, living rooms, and bathrooms. Beyond the luxury of warm floors, underfloor heating can:
- Improve comfort with even heat distribution
- Free up wall space by removing radiators
- Lower your energy bills over time
- Enhance the resale value of your home

What temperature should underfloor heating be set at?
A typical underfloor heating system runs best between 21°C and 25°C for floor temperature depending on floor finish manufactures instructions, with a room air temperature around 19-22°C. If using a smart thermostat, you can fine-tune it to suit your needs and maximise comfort while minimising waste.
What temperature should underfloor heating be set at night?
At night, you can reduce the temperature slightly to around 16-18°C, depending on your comfort level. This helps conserve energy without letting the room get too cold. Smart controls can help automate this change.
How to bleed underfloor heating?
Bleeding a wet underfloor heating system removes trapped air from the pipes, which can prevent parts of the floor from warming up.
This is normally done by flushing the system or individual loop. The team at KD Jones is fully equipped to handle all maintenance for water underfloor heating systems, keeping your system running smoothly.
Can you have underfloor heating under carpet?
Underfloor heating can be used under carpet, but it’s important to choose the right type of carpet and underlay. The combined thermal resistance (also known as the TOG value) should not exceed 2.5 TOG to allow effective heat transfer.
We can advise you on suitable materials and floor finishes during the design stage to ensure your system performs at its best.
