@Buttmunch5000 reply part 2 of 2:
Heat pumps are ideally suited to lower heating flow temperatures i.e. 50 deg c for appropriately designed radiator systems or under floor heating systems of between 35-40 deg C. The DHW function raises the temperature to our standard setting of 58 deg C or higher depending on the needs of the customer.

Thanks for your query. Our GSHPs can supply both central heating and domestic hot water up to 65 deg flow temperatures. There is sufficient energy in the ground to be used to heat up the refrigerant in the heat pump circuit to a more useful temperature to provide a normal flow temperature of 58 deg C. The heat pump has an auxiliary heater which supports the need for temps up to 65 deg.

I have been researching systems like these for a while now , and it seems that ground source heat pumps do have a future in home energy but i cant see them being relied upon for hot water as it normally tops out at 50C where as gas boilers can get it up to 90C if required, that is a big limitation, but using solar heating exchangers on the roof it might work.
But for heating of a house it is a good system and will gain more traction in the coming years , the cost is about 6 years of gas,small

Hi joop1977, thanks for your query. Technically this could be done, however, it may be rather complicated: the houses would need separate controls and perhaps separate hot water cylinders. Practical considerations such as splitting the bill and selling the houses in the future would also have to be taken into account. Our Technical Support department can offer more advice – visit our website or call 0844 892 3366. Hope this helps.

Could this be used as a shared system with other propertys to save on cost?

Thanks for your comment spider00998877. Ground source heat pumps can cost between £7,000 – £13,000 to install (ref Energy Saving Trust) and can offer significant savings compared with boilers. They’re ideal for new builds or retro fits. All our products are backed up by our nationwide service department.

looks expensive to buy and even more expensive to install and lets nor even think about getting someone to repair it when it goes wrong!!
