[QUOTE="mountfarm, post: 7901818, member: 90390"] Dave: 110 uno underground pipe swapping to 40 to get it into the garden shed next to the house where the heat meter is. It then is 25mm copper pipe into the heat exchanger. To me the flow and return pipe in and out of the heat exchanger are very similar temps (to the touch). I need to get a clamp thermometer for some accurate readings but I dont think they’ll be anything in it. 100 metres away in the biomass plant room the temps for start up are 70 and shut down 85. This is measured accurately in their digitally. 100m in another direction we have a temp read out in a grain store fan house and it sits happily at 75 so there isn’t much heat loss. Obviously the grain drier is not on at this time of the year so not sapping heat. Wis: Auto valve is still in the system but it’s working correctly. If the biomass looses heat due to fuel supply the auto valve kicks in. The underground pipe run has not changed. The pump is new and the filters in the system are clean as we check every few days. The whole system has been bled for air numerous times. [/QUOTE]
