Recently had a new immersion and cylinder fitted as the old cylinder had split.
Since this has been done we seem to have an airlock in the hotwater pipes of the back boiler. We can feel where the pipes are scorching hot and then become cold.
If i use the immersion I can obviously get hot water, but if i turn the immersion off (which is how we usually would have it) and try and get hot water and central heating from the back boiler, we don't get any.
If the water alone is on, we get a lukewarm water. If we have the central heating on and the hot water then we get no hot water.
We have had two plumbers round and neither can find anywhere to release this airlock, which i find strange. They have both told me the same, to leave the hot water on and hopefully it will push itself out (or something along those lines!)
Does anyone have any ideas as to remedy this situation - we are seriously considering a new boiler - although don't want to do this as the second plumber said our back boiler isn't 'that' old - (an 80s one he said) and we shouldn't need to.
any help greatly appreciated as we're freezing without the heating on!!!
