Low Temperature Heating Systems for Modern, Energy-Efficient Home Heating
If your home is well-insulated, a traditional high-temperature heating system could be costing you more than it should. Low-temperature heating provides a smarter, more efficient way to stay warm, delivering comfort while reducing energy use and bills.
When paired with a heat pump, it’s even better. Both technologies are designed to work at lower water temperatures, so combining them can unlock exceptional efficiency and long-term savings. Join homeowners across Brighton, Hove and Worthing in upgrading to a more efficient heating system.
What is Low Temperature Heating?
Low-temperature heating warms your home at lower water temperatures than traditional boilers or radiators. Instead of pumping water at 70–80°C, it typically operates between 35–55°C. That means it uses less energy while still keeping your home comfortably warm.
Common setups include underfloor heating, oversized radiators and advanced heating controls - all of which help maintain an even, gentle heat throughout your home.
While low-temperature heating can be installed without a heat pump, it’s most effective when both systems are designed to work together. A properly matched setup makes it easier for your heat pump to run efficiently and extends its lifespan.
Why Choose Low Temperature Heating for Your Property?
Low-temperature heating systems are built with efficiency in mind. By running at lower water temperatures, they keep your property warm without wasting energy. This makes them ideal for insulated homes, renovations and new builds focused on sustainable comfort and reduced running costs.
If you already have a heat pump - or are thinking about getting one - upgrading to larger radiators or improving your heating controls can make a huge difference to overall performance. These adjustments help your system circulate warmth more effectively and maximise the efficiency of your heat pump.

The Benefits of Low Temperature Heating
Low temperature heating is hugely beneficial for domestic properties in Brighton, Hove and Worthing. From lowering your energy bills to reducing system failures, there are numerous benefits to enjoy. Let’s take a look at five of the most prominent:
Energy efficiency
Lower operating temperatures mean less energy use, reducing bills and carbon emissions
Even Heat Distribution
Systems like underfloor heating provide consistent warmth throughout your home
Optimised for Heat Pumps
Designed to work seamlessly with modern renewable systems, boosting performance and efficiency
Improved Comfort
Gentle, steady heat is more comfortable than the sharp bursts from older systems
Reduced wear and tear
Lower water temperatures mean less stress on your heating components, slowing corrosion and minimising cavitation.
Long-term Savings
Energy efficiency and reliability add up to meaningful cost savings over time
How Low Temperature Heating Works
Low-temperature heating systems circulate water at a lower temperature - typically between 35°C and 55°C - creating a softer, more consistent warmth.
Common types include:
- Underfloor heating: Warm water flows beneath the floor to gently heat the space above
- Oversized radiators: Larger surface areas release the same heat output with cooler water, perfect for pairing with heat pumps
- Heat pumps: These systems extract renewable energy from the air, ground, or water and deliver it efficiently through your low-temperature heating system
By matching your home’s insulation, radiators and controls to your chosen heat source, you can achieve optimal comfort and efficiency.
How Much Does Low Temperature Heating Cost?
The cost of installation varies depending on your system type, property size and whether you’re upgrading an existing setup or starting from scratch.
Typical price ranges:
- Underfloor heating: £50–£90 per m²
- Oversized radiators: £300–£600 per radiator
- Heat pump systems: £8,000–£14,000 (including installation). This is minus the government Boiler Upgrade Scheme grant which can reduce the overall cost by up to £7,500.
Although upfront costs can be higher than traditional systems, low-temperature heating offers long-term savings through improved efficiency and lower energy use.

FAQs
Here are some of the most common questions we get from homeowners across Sussex about low temperature heating.
No, but it’s highly recommended. Low-temperature systems can work with traditional boilers but they’re most efficient when paired with a heat pump, as both operate best at lower temperatures.
Yes, in most homes it’s possible. However, you might need larger radiators, upgraded pipework, or better heating controls to help your system run efficiently at lower temperatures.
It can be, provided your home is well insulated. If insulation is lacking, you may need to make a few upgrades first. We can connect you with trusted suppliers who can help.
Absolutely - underfloor heating and heat pumps are a perfect match. Both systems run efficiently at lower water temperatures, providing even, comfortable warmth.
No, once installed, it’s highly efficient. Because it uses lower temperatures and distributes heat evenly, it often costs less to run than traditional radiators.
Larger radiators have more surface area so they can deliver the same level of warmth even with cooler water. This is essential for getting the most from your heat pump.
Not necessarily. We’ll assess your existing system - in many cases, only key radiators need upgrading to maintain comfortable temperatures throughout your home.
Yes, smart thermostats and weather-compensating controls work brilliantly with these systems, helping fine-tune performance and energy use.
