    Air in hot water circuit after draining system?

    Yes, both C/H and hot water pumps just bleed water.

    Air in hot water circuit after draining system?

    I undid the knob and some blackish water came out, no hiss/ no air so I didn't pursue it any further. The chap how did the drain down reckons the only way is to beed all the rads again, I already did that a second time and there was very little aircame out. Is this the only way to get air out as...

    Air in hot water circuit after draining system?

    Sorry Im not into this plumbing lingo, are they those like small size Stilson grips? I have a big pair or mole wrench but would not use either as butchers soft metal like brass.

    Air in hot water circuit after draining system?

    I tried that but it wont budge, should I put some pliers round it? I dont want to put too much force on it as its only 15mm copper.

    Air in hot water circuit after draining system?

    Yes, it looks like the top picture but it has a knirled roudn finish not flats on it and its on the end of a pipe that is on the c/htg flow side just after the pump but inside the boiler casing. Can you unscrew half a turn when the system is off/cold? It has been on ever since the boiler was...

    Air in hot water circuit after draining system?

    Recently did a complete system drain and refill. All rads are nice and evenly hot, but hot water is not as hot as before. The hot water system that has a circ. pump and seems to have air in it as when the C/ H stat goes to off the boiler doesn't fire up for ages until the hot water flow pipe...

    Hot water circ. pump overflows hot water into F&E cister

    If I had the system upgraded what mods would be recommended to stop the boiler short cycling? I dont want the expense of a complete replumb for separate hot water or heating. I have a motorised valve on the flow side of the hot cylinder but its never been wired in as I didnt know how to wire...

    Hot water circ. pump overflows hot water into F&E cister

    I meant, as it is working against a restricted pipe area ahead of it. Anyway the overflow has stopped and I with the heating on the expansion pipe up to the loft above the T piece into the hot tank no longer gets hot higher than a foot or so. The speed selector is on "1. Should I drain...

    Hot water circ. pump overflows hot water into F&E cister

    No, the pump is pushing water towards the boiler on the return side and that is the same direction as before. I have now throttled the output valve from the pump until water stopped coming out of the overflow. This was when the bolier was off. Suppose I will have to turn it down a bit more when...

    Hot water circ. pump overflows hot water into F&E cister

    It was 55 for the pump plus fitting. I have been told elsewhere to partially close the shut off valve on the pumping side to reduce the output of the CP pump. For all I know it could have been partially closed with the old pump when it was fitted. I didn't know about this oxygenating thing...

    Hot water circ. pump overflows hot water into F&E cister

    Now your got me worried, I suppose this is circulating round the system from the F&E tank. I was charged 55 pds for the pump by a reputable local company called Paine Manwaring who claim to be heating engineers but it was needed in a hurry as the old one failed so no hot water. It IS on the...

    Hot water circ. pump overflows hot water into F&E cister

    My C/ Heating system orginally had one pump and gravity fed hot water heating the hot cylinder upstairs. About 15 yrs ago we had the boiler moved into the utility room and the hot water didn't get hot as it couldnt gravity feed round the added pipe bends from the utility room into the kitchen...
