    Hot Water system Airlock

    Hi Oilman Yes I still have the problem. I have flushed it this saturday afternoon if it follows the same pattern it won't last long before we have no hot water again. Regards

    Hot Water system Airlock

    It flows into the expansion tank via a pipe at the bottom of the expansion tank. When I shut a value off fitted to this pipe, it then flow into the tank via a pipe that loops into the tank over the top. It looks like the pipe at the bottom of the expansion tank is connected to the cold side...

    Hot Water system Airlock

    Thanks, Would the reverse flush have shifted the blockage though? It does seem to flow in to the expansion tank OK.

    Hot Water system Airlock

    Help I have a problem that has just started to affect our hot water system. We have pumped CH and gravity fed HW, but just lately we have no hot water. I have tracked it down to what appears to be an airlock, as it is hot coming out of the boiler but cold on the HW tank inlet. Somebody...

    Pumped CH Overflow

    Hi all, Many thanks for the reply to my enquiry, lets see if I can provide answers to your questions. DaveJ: There are four 22mm pipes used for the HW and CH, there is a separate 15mm pipe supplying the gas to the boiler, sorry for being little misleading. :oops: sifu: Thanks for the...

    Pumped CH Overflow

    Thanks sifu It is a pumped CH system only, separate HW supply from the boiler (it appears). As there are four pipes at the boiler, which I presume to be supply/return for the HW and CH, the pump (two speed) is set to the lowest setting and looks like it is on the return side of the CH...

    Do you think this is the hot water tank? :?

    Pumped CH Overflow

    Well the water level did not drop after it had cooled down, in all it rose about one inch. It seems that the water level only rises when the system is in operation, not when off. Any ideas?

    Pumped CH Overflow

    Hi oilman, I currently have the ball cock tried up with the heating running, the water level has increased about half an inch in about 3 hours, it did not do this when the system was turned off all afternoon, the water temperature is now fully up to temperature. I want to see how much the...

    Pumped CH Overflow

    As access is difficult to the main cold water tank, I tied up the ball cock of the expansion tank an emptied it to the level of the lowest pipe. I left this all afternoon with no increase in water level. I then turned the hot water on (as this is not pumped) this showed a slight increase in...

    Pumped CH Overflow

    Thanks masona, I'm just about to go and remove the excess water from the expansion tank now, which should last about three days. It was the boiler stat I replaced and both the main water tank and expansion tank are on the same level. I will have a look and check if the water level is the same in...

    Pumped CH Overflow

    Thanks oilman, I can understand that a leak could put extra water into heating system causing it to overflow, but I can't see how it would cause the water to appear to be pumped into the expansion tank. It seems to overflow (when the expansion tank is full) about 20minutes after starting...

    Pumped CH Overflow

    Thanks for the advice. I checked the pump speed and it was set on the lowest speed. I have now replaced the thermostat but the system still overflows after three days... What else could I try?
