I’m not a heating engineer but I’m fairly knowledgeable on the way systems work. But I have come across an issue which I’m wondering is common.
Earlier this year I had a fully licensed engineer install a new baxi combi in a property I’m doing some work on. Great job done without any problems.
Last week the owner mentioned that the shower (which is a aqualisa with a conversion box fitted to work with the new combi boiler) wasn’t getting hot.
I thought it was “user error” but having spent some time their today I cannot get it to run hot. I thought it might be the conversion box from aqualisa but the other shower which is a standard mixer unit is the same.
When I investigated further, I can get hot water out of the sink taps but as soon as I put the bath on full, the hot water drops to “quite hot”. The actual temperature that the boiler shows is 60 degrees when the sink taps are on but only 51 when the bath or shower taps are fully on.
It would seem that the boiler isn’t strong enough to heat a large enough volume of water to feed the bath or shower if the water temperature coming in from outside is too cold. And with current outdoor temperatures about freezing, this is a problem.
Or as I said, am I being dumb?
