Is Energy Saving Possible with Underfloor Heating?

Underfloor heating systems are considered one of the most efficient heating solutions today, thanks to their ability to operate at low temperatures, provide homogeneous heat distribution, and integrate seamlessly with modern heat sources. Especially during periods of rising energy costs, one of the most frequently asked questions is:

Does underfloor heating really provide energy savings?

In this article, we explain the operating principles of underfloor heating, its energy-saving potential, cost advantages, and the technical benefits offered by KAS Therm underfloor heating systems.

How Underfloor Heating Works

Underfloor heating works on the principle of heat rising naturally from the floor upwards. Heating pipes are installed beneath the flooring, and warm water circulating through these pipes heats the floor, creating a balanced and comfortable temperature throughout the space.

The main reasons why this method provides energy savings include:

  • It operates at low temperatures (typically 30–45°C).
  • Heat is distributed evenly across the entire floor surface.
  • There is no localized overheating or heat loss as seen in radiator systems.
  • Because heat is distributed uniformly, the heat source consumes less energy and reaches the desired temperature more quickly.

How Much Energy Can Underfloor Heating Save?

According to standard building simulations, underfloor heating systems provide:

  • Up to 30% energy savings compared to classic radiator systems.
  • Lower energy consumption due to low operating temperatures.
  • Even higher savings when used with innovative systems like heat pumps.

The exact rate of energy savings depends on:

  • Quality of insulation
  • Type and density of heating pipes
  • Floor covering
  • Type of heat source (boiler, heat pump, etc.)
  • Use of smart room thermostats
  • Installation quality and hydraulic balancing
  • Use of flow-controlled manifolds with built-in flow meters

8 Main Reasons Underfloor Heating Saves Energy

1. Low Water Temperature Operation

Radiators require high water temperatures due to their limited surface area.
Underfloor heating covers a wide area, enabling efficient heating even at 30–45°C.

2. Homogeneous Heat Distribution

Radiators accumulate heat around the source, causing the system to work harder.
Underfloor heating distributes heat equally from every point of the floor.

3. Reduced Heat Loss

Lower temperature differences result in minimized heat loss.

4. Full Compatibility with Heat Pumps

Heat pumps operate most efficiently at low temperatures.
Underfloor heating significantly improves the heat pump’s COP (Coefficient of Performance).

5. Easier Thermal Comfort

A warm floor provides comfort even at slightly lower room temperatures.
This allows the system to operate 1–2°C lower, reducing energy consumption.

6. Dynamic Control with Room Thermostats

Each room can be controlled independently.
Unused areas can be set to minimum heating levels.

7. Low Air Circulation

Less air movement results in less heat loss—improving overall energy efficiency.

8. Large Heating Surface Area

The entire floor acts as a large radiator, heating larger areas with lower energy use.
