Hello
I have recently moved house and I am discovering some horrors with the central heating system.
I'm skint at the moment after shelling out for the place so doing my best to DIY as much as practically possible.
My knowledge of traditional heating systems is very low, (my last place was a combi boiler system) but what I have noticed is that when the heating is on and the pump is active that a considerable amount of water is being pumped into the expansion tank and this is not good.
I don't have much knowledge about these things but I think the position of the pump is not helping.
Here is a photo taken next to the boiler on the 1st floor...
The expansion tank is about 1 - 2 m directly above where this photo is taken in the loft.
What I can tell is that the hw water is coming up from the boiler / tank up through the bottom left into the pump.
The pipe going directly above the pump into the loft via the reducing tee is going into the top of the expansion tank.
The pipe top right is feeding water back from the expansion tank.
The central heating circuit follows the pipe bottom right.
This might be a silly observation but is one big factor that the pump / pipework is positioned incorrectly as the easiest path for most of the pumped water is to go up rather than go around the 180 bend?
My temporary fix has been to turn the pump down to the lowest speed but that only reduces the amount of water flowing into the expansion tank and isn't heating the more remote radiators as effectively as the higher settings.
Is there some sort of valve I can buy that might help or do I need to redo the way this is laid out?
Thanks very much
