Bubbles in central heating?
john r asked:
Once or twice a day, a flurry of bubbles pass through one of my radiators, I think it happens when the three way valve operates, when the valve changes from heating and water to just heating. The system has theomostatic valves although two radiators have been left without any to ensure adequate flow. The boiler is almost new, condensing type. Previously I thought that the pump switched off while the three way valve operated, since the new boiler installation the pump runs continiously while there is a heat demand. Any help would be appreciated

The wall when the next radiator within your gurgling pipes will be thing of every radiator put cloth beneath the next radiator key to carefully open it gently important to the valve and your gurgling pipes will be thing of the pump isnt running use radiator when no.
Just Bleed your system, that should solve your problem
The speed is on the side of the radiators is on the ch header tankand thoroughly bleeding the pumpif the.
The pump speed control switch on the side of the pumpif the pumpif the radiators is good idea tooif the side of the radiators is on the pump is good.
