Hi,
I have an (old) Worcester Bosch 230 combi boiler downstairs in the kitchen and a Mira one dial type mixer shower upstairs in the bathroom.
Of late, after turning the shower on, the water heats up for a few minutes (the boiler fires up) and then the boiler shuts off and the water goes cold. The hot water doesn't return unless the shower is switched off and on again after a few minutes.
When the hot tap is run (as a hot dribble) in the upstairs bathroom, the shower behaves itself and the temperature remains constant.
Would anyone happen to know any possible reasons for this? The pump and the hot water/CH valve) on the boiler has been replaced (approx. one year ago). No other plumbing works have been done excepting a recent shower head replacement (not like for like). I don't think the new shower head would benefit from a flow reducing device as it does not exceed the flow test in the free eco kits you can get.
Any ideas?
Thanks in advance,
Andy
