Underfloor heating is one of the most efficient and comfortable ways to heat your home. When combined with a modern boiler system, it offers enhanced performance, improved energy savings, and a more streamlined way to control your heating.
If you're considering adding underfloor heating to your home or already have a boiler system in place, here's how the two can work together, and what you need to know before getting started.
Why Combine Underfloor Heating with a Boiler?
Water-based underfloor heating systems run at lower temperatures than traditional radiators, making them perfectly suited to work with modern condensing boilers. Together, they create a more energy-efficient heating system and deliver consistent warmth across your home.
Benefits of combining underfloor heating with a boiler:
-
Lower energy bills – works at lower temperatures, reducing energy consumption.
-
Greater efficiency – Modern boilers are built to maximise performance, especially when running alongside underfloor heating.
-
More space – With no bulky radiators, you have more design freedom.
-
Customisable control – Advanced thermostats make room-by-room management simple.
Boiler Types That Work with Underfloor Heating
✅ Combi Boilers
Combi boilers heat water on demand and are suitable for small to medium underfloor heating installations. For larger systems, you may need a buffer tank to maintain flow rates.
✅ System Boilers
With a separate hot water cylinder, system boilers are ideal for multi-zone setups and homes with higher hot water demand. They integrate well with water-based underfloor heating systems.
✅ Regular Boilers
Also known as conventional boilers, these are compatible with underfloor heating when using the correct valves and controls, though they're typically found in older homes.
How They Work Together
-
The boiler heats water to the required temperature.
-
A mixing valve reduces the temperature to underfloor heating-safe levels (usually 35–55°C).
-
The manifold distributes water to each heating loop across the property.
-
Thermostats in each room give individual temperature control.
With this setup, underfloor heating doesn't just work—it thrives. You get consistent comfort without the spikes and drops that can come with traditional radiators.
What to Consider Before Installation
1.Boiler Capacity
Check that your boiler can handle the added demand from underfloor heating—especially important in larger properties.
2.Smart Controls
Use programmable thermostats to tailor heating schedules by zone. Many models can connect to mobile apps for remote access and usage tracking.
3.Floor Build-Up
Installing underfloor heating increases floor height slightly. Plan for door clearance, skirting adjustments, and transition thresholds between rooms.
4.Professional Installation
Underfloor heating should be installed by experienced professionals to ensure safety, performance, and compliance with regulations.
Track Energy, Tailor by Floor Type & Go Smart
Pair your underfloor heating with a thermostat like the ProWarm ProTouh-E WiFi Thermostat. It offers features such as:
-
Touchscreen control
-
Holiday mode & frost protection
-
Energy usage tracking
-
WiFi app connectivity for remote control
-
Programmable heating schedules
These features help you fine-tune your heating to your lifestyle while keeping energy use in check.
