Got a heat exchanger plumbed in a house which is fed directly from the biomass boiler. The flow pipe is hot and return pipe is warm so we are getting heat into the house. However there doesn’t seem to be enough heat being utilised as the house is just luke warm.
if we put the motorised valve into manual then we get more heat in the house but then the return pipe is also red hot so we are sending heat back to the biomass boiler. Our plumber who fitted and knows this stuff is not contactable so anybody seen this before.
The motorised valve seems to be working in auto as it opens and shuts but we don’t seem to be getting the full heat into the house.
Checked radiators for air etc and they are fine as it’s also luke warm in the shower/baths.
