Boilers and underfloor heating: an overlooked duo.

Step onto modern comfort
The perfect blend for home comfort.
Underfloor heating is an efficient solution that works by distributing heat evenly across a large surface area at low temperatures. This approach ensures consistent warmth throughout your home, making it a popular choice for those seeking modern, effective heating solutions.
When paired with a boiler, such as our boiler, underfloor heating offers reliable and cost-effective warmth, enhancing comfort while maintaining energy efficiency.
Teamed up with a boiler
Advantages of combining a boiler with underfloor heating.
- Low-temperature heating systems.
Unlike radiators, underfloor heating can operate at a lower flow temperature (around 30–50°C) which can increase your boilers efficiency (compared to 65–75°C).
- Zoned heating capability.
Provides the ability to divide your underfloor heating into zones for individual temperature control in different rooms. A boiler, such as the ecoTEC plus, can deliver hot water precisely where and when it's needed.
- Compact and space-saving design.
Maximise your home's space by eliminating the need for radiators or a hot water tank. A boiler fits seamlessly into most homes, complementing the sleek, clutter-free appeal of underfloor heating.
- Reduced installation costs.
Streamline your system by using a boiler with underfloor heating, which can reduce overall installation costs.
Types of underfloor heating
Two systems to warm your feet.
- Wet systems
- Dry / electric systems
Wet systems circulate warm water through pipes, evenly warming floors for a cosy environment. They pair well with boilers like the ecoTEC plus and can integrate with renewable sources. Installation involves laying pipework beneath the floor, offering a durable, low-maintenance solution. Ideal for larger spaces, they heat extensive areas, freeing you from radiator constraints and allowing flexible furniture arrangements.
How does underfloor heating work with a boiler?
- 1/4
The boiler heats water to a lower temperature, ideal for both wet and dry underfloor heating systems.
- 2/4
In wet systems, this warm water circulates through pipes beneath your floor.
- 3/4
This ensures the floor radiates heat evenly throughout the room, maintaining a consistent and comfortable temperature.
- 4/4
With zoned heating controls, you can adjust the temperature in individual rooms, giving you complete control over your home’s heating system.
Optimal performance
When you need to upgrade your boiler.
If you happen to have a very old boiler the compatibility with an underfloor heating might not be given or optimal. As it might not be suited for low-temperature heating or doesn't have the capacity to heat the floor and other parts of the house. In these cases it's smart to replace your boiler with a new one. With a new Vaillant boiler you opt for reliable and flexible heating that ensures to build a dream team with your underfloor heating.
Heating system comparisons
Underfloor heating vs. radiators: how to choose what's ideal for you.
| Feature | Underfloor heating | Radiators |
|---|---|---|
| Operating temperature | 30–50°C (efficient with boilers) | 65–75°C (higher boiler demand) |
| Heat distribution | Even across the floor | Concentrated near the radiator |
| Boiler efficiency | Lower temperature demands improved boiler efficiency | Higher temperature demands reduce boiler efficiency |
| Response time | Slower to heat but maintains warmth longer | Heats quickly but cools down faster |
