Posted By: Paul in MontrealIt can't recover more heat than it loses
Posted By: James NortonOption for 'summer bypass' (whatever that is)
Counter flow heat exchanger (...?)
Also what about running the inlet ducting underground for pre heat...? good idea / diminishing return...?
Posted By: Ed DaviesIf the ground around the ducting is to ever be warmed then you need to run air through the duct which is warmer than the ground. This runs the risk of condensation and hence mould.
Posted By: James NortonPSHas any one heard anything about the 'PAUL' units supplied by GBS...? I suspect top notch performance but big price tag...?J
Posted By: James Norton Good to know that my suspicions about £ insanity were correct. Have looked into it a bit more since posting I'm seeing common things in nearly all from the sub £1k to the '£insane'.
Posted By: Paul in MontrealLots of space for ducts and the like though!
