Elcarajillo Will do. Those two haven’t budged despite best (careful) efforts. Will keep trying. I think the boiler, water tank and the pipes need sorting out.
One of the engineers already said we need to simplify and update, while another said mega flow as it is a big property. We don’t need a mega flow for a family of 3, do we?
Btw, the hot water ran again for 30 mins. This normally gives hot water, where we can’t set it at max at the shower. With nothing changed, the Gran at home said at noon that she had to keep the tap at max to give herself a hot shower. I running tap hot water temp was about 41C-42C.
Don’t know what had changed. I thought the engineer didn’t check properly and gave us all good test certificate. Perhaps, he won’t know unless we tell him this is an issue now. Shouldn’t the issue, if it is, with that boiler pop up when a routine service is done?
