Replaced Wilo pump had problem's with noise reduced the speed to 2 since then i have a problem with Hot water system when hot water is on pump cuts out and hot water vents into the expansion tank in the loft
Do i need to increase the pump speed because water is not moving quick enough The feed pipe to hot water is warm return pipe seams to be cold
