I have a pressurised system run off an oil fired boiler. The pump is on the return. The system appears to run from the bolier straight into the immersion tank and then onto the radiators. There is a thermostat at the bottom of the tank which appears to control the pump. I have a problem where the radiators upstairs work (excluding the bathroom) but none of the down stairs work unless you turn off the upstairs rads.
My plumber has tried putting a valve in to shut off the flow to the tank , this appeared to make very little difference, he then tried putting a larger pump into the flow side , this made little difference , in fact the pump burnt out ( we don't know if it was a faulty pump as it was cheap or some blockage). We have now power blasted the whole system and put a pump back into the return (not wishing to risk another burnt out pump), but we are back to square one.
I think the system may have been originally a gravity fed system as there used to be a Franco Belge in the kitchen which used to feed the system and I think the present system was cobbled from this. Is it possible there is a 'gravity' valve in the system which has clogged ?.
Anyone reading this will probably become aware I know nothing about central heating systems. Help would be greatly appreciated.
PS Both my plumber and boiler service engineer say that they have never seen a system like this !
