What are ambient
loop heat networks?
Cleaner, greener heating
Most traditional heating systems rely on burning gas to create heat. Our ambient loop system is different.
Your heating will work just as you’d expect, but with the benefit of no gas in your home. Instead, our heat network uses renewable heat from the air and delivers it efficiently to homes, helping to reduce carbon emissions, improve energy efficiency, and support the transition away from fossil fuels.
Every 1 kWh of electricity generates 3 to 4 kWh of heating – providing 100% heating and hot water needs throughout the year. That is…
3-4 times
more efficient than gas. This means more heat is produced using less energy, helping keep running costs lower.
What is an Ambient Loop Heat Network?
Instead of each home relying on a gas boiler, heat is taken from the air by a central air source heat pump and circulated at a steady, low (ambient) temperature through insulated pipes. Each home then uses a small, efficient heat pump to raise that ambient heat to the temperature needed for space heating and hot water in your home.
This approach combines the benefits of centralised renewable energy with individual, in‑home control.
How the Ambient Loop Heat Network works
1. Collecting heat from the air
A central large-scale Air Source Heat Pump absorbs heat from the outside air. Even on cold days, there is still heat in the air.
2. The Ambient Loop Heat Network
The heat generated by the large scale air source heat pumps is circulated around the building through a closed loop of insulated pipes filled with water to your homes water source heat pump.
3. The Water Source Heat Pump
Inside your home is a Water Source Heat Pump. This heat pump uses electricity to boost the temperature to the level needed to provide heat and hot water to your home.
Why Ambient Loop heating is more efficient than gas
Uses renewable heat
Unlike gas boilers, which burn fossil fuels to create heat, Ambient Loop systems capture renewable energy from the air. This reduces carbon emissions and supports national net‑zero targets.
More efficient
Heat pumps are highly efficient because they move heat rather than generate it. For every unit of electricity used, a heat pump can typically deliver three to four units of heat. This level of efficiency is far higher than traditional gas boilers.
Lower heat losses
Because the Ambient Loop operates at a lower temperature than conventional heat networks, much less heat is lost as water travels through the pipes.
No combustion in the home
There is no gas burning inside the property. This removes flues, reduces maintenance needs, and improves indoor air quality.
Benefits of Ambient Loop Heat Networks
Heating all year round
The Ambient Loop provides a consistent heat source, whatever the weather outside.
Individual control
Your heat pump is connected to your own electricity meter. You only pay for the electricity your heat pump uses to boost the hot water in your central heating system.
Energy efficient
For every 1 unit of electricity used by your heat pump, it can produce 3 to 4 units of heat, making it more efficient than a gas.
Better for the environment
Because Ambient Loop Heat Networks don’t use gas, they create less carbon emissions, supporting greener living.
Maintained by us
We’ll service your heat pump every two years. All servicing, repairs and replacements are included in our service at no extra cost to you, so there’s no unexpected bills to worry about.
Future proofed
As the UK electricity grid becomes greener, your heating becomes even more eco-friendly without you having to change a thing.
Supporting low-carbon and the Future Homes Standard
Ambient Loop Heat Networks play a key role in supporting the UK’s transition away from fossil fuels:
- They align with the UK’s Net Zero 2050 targets by eliminating fossil fuel use for heating
- They are compatible with the Future Homes Standard, which aims to significantly reduce carbon emissions from new homes and avoid reliance on gas heating
