How This Would Work

The new Future Homes Standard 2025 comes with the replacement of Combi-gas Boilers. Air Source Heat Pump’s comes with high costs, both to the Home Builder and the House Owner, along with inconsistent heat, noise and space complaints. CHRS can sort all those issues, is grant eligible, and has low OPEX costs. The Perfect Solution?

You will strip all the thermal heat from the clay and your output will drop.

No, CHRS is advanced that within each stack, the loops are split to ensure hydraulic balance, each loop is temperature monitored and each loop can be individually closed, while the remaining loops remain online to allow thermal recharge. Additionally, the system is bi-directional, meaning the heat is captured at both ends of the stack to maintain temperature uniformity.

You won’t be able to meet the demands of every household using the system at once.

Once the hot water supply ring main is up to temperature, the two heat pumps are shutdown, and one of two circulation pumps remains online to circulate the hot water around the ring main which feeds an HIU within each household. If the ring main temperature drops below a designated temperature, i.e. 65 degrees Celsius, then the CHRS opens the stack loops needed one by one to prevent thermal shock, start the heat pumps and recharge the hot water ring main until demand is no longer needed. This is unique, smart thermal-harvesting.

You will probably only heat 10 – 20% of the homes built.

We have stacks at lengths between 200m and 800m, each is sized for the estate, plot or site needed. Even one 200m stack can support about 60 homes with 50+ years of low-carbon, sustainable heating and hot water 24/7, 365-days of the year. The table below shows the direct proportional scaling of each stack.
