Hi
I may not have the correct term but i think the water is flowing around my central heating system backwards and resulting in poor performance in terms of even heat output from the radiators. Let me explain and i'd like some input.
I had a new boiler fitted when we did a kitchen extension a couple of years ago and hot water has never been a problem but i have noticed that the radiators heat up unevenly, ie some are pretty hot and others a only warm. Its not really been a massive problem more something that annoyed me so i started to look at balancing the system to try to even things up. One of the tasks in balancing seems to be trying to ensure a 12 degree temp drop between inlet and return valves. In investigating this its clear that every single return valve is HOTTER than every single inlet valve which strikes me as the flow going actually being pumped around the wrong way. I guess this was just a massive installation mistake but has anyone heard of that before or equally what can be done about it? I do know that i didnt think much of the plumber when he installed everything but its evidently clear if my suspicions are correct that he may have been a plumber but he certainly isnt a central heating engineer!
The boiler is a Worcester Bosch and the CH is a vented system with a couple of motorised valves, one that operates the radiators and the other which send water to the hot water tank.
Is my guess at water going the wrong way likely to be true?
