Ground source heat Pumps

[darren bastin]

went today to repair some steel heating pipes in a massive old building. pipes are as rotten as a pear. Customer informed me that they are having the existing heating and rad pipework (which by the way is a one pipe system) linked up to a ground source heat pump. My understanding is that the flow and return temps are 45 degrees so you have to increase rad sizes etc Also would the system have to be sealed ? Cust adamant that no upgrading is happening within the building.

Does any body want to comment ?

Sounds like a recipe for disaster

sounds like a recipe for disaster! yes the system would be sealed due to the higher flow rates can't see any bonafide company taking this on without upgrading rads and pipework

Especially in a big old house with a high heat loss/demand :cowboy:

not a cat in hells chance of an old one pipe system being functional let alone efficient when heated by any heat pump, air or ground source.

Thanks for the replies lads. It would appear that we are ever so slighly sceptical of these proposals. The place will be so cold even the ghosts will move out.
