Hi all,

I wonder if anyone can offer me some advice please?

Currently I have a six year old Biasi Combi Bolier, recently (last week) I lost my heating and ho****er. I'm covered under insurance so called the engineer out to come and see what the problem was. After checking, he said that it needed a new PCB, he replaced it. Did all the checks on the boiler and left.

Heating was fine, and still is. The same night that the boiler was 'repaired' the water temperature in the bathroom (all mixer taps, shower is a thermostatic mixer) went cold. The water fluctuates between ice cold to tepid at best. The flow is fine, I have checked the temperature setting on the boiler output and it is the same as its always been. The water in the kitchen (mixer also) is totally fine and is putting out really hot water. Reducing the flow in the bathroom doesn't seem to help unless you set it to a dribble (40 mins to fill a bath).

I called the insurance people again, an engineer came out. Looked at the boiler, listened to my story and then he told me that it could be water 'cross over' that cold water could be pushing against the hot and going down the hot water supply. He then went on to isolate the bathroom sink cold tap, switched the hot tap on and said its not that one. He said that I would have to do a similar thing with the bath and shower. He ended up saying that it wasn't a boiler problem as its firing fire, its a plumbing issue!!!!

Personally I find it very coincidental that the PCB was replaced and now no ho****er upstairs and normal downstairs, what are the chances of boiler needing repair, getting fixed and then a random plumbing issue with hot water.

I don't want to call a plumber out yet as this isn't covered under my insurance and I have a feeling he will tell me its a boiler issue, catch 22.

Can anyone please shed any light on what you may think the problem could be?

Thank in advance
Damo
 
I should add the kitchen & basin were fine but the bath & shower in a cubicle went hot & cold

When it happens have you looked at the boiler pressure guage? Mine was moving.

I'm sure a boiler engineer will know the answer

Quite often you can repair one fault only for another to rear its head
