No hot water upstairs

[Gasmk1]

what boiler is it, from description your tap upstairs does not have enough flow to allow the hot water flow switch to activate. It is more Than likely a boiler problem so get a RGI to look at it

Could be the flow switch but strange that no hot water upstairs with both hot tap and shower both on, hot tap gives > 7 LPM on its own, hot tap downstairs may give a very high flowrate but does look like boiler (oil or gas) fault.

We’ve spoke to a few people today and they have suggested it could be the Diverter valve or something? Does this sound like something it could be?

I said flow switch to make it easier for you to understand that is why I asked which model of boiler is it

Oh I see, it’s a ideal c30 independent

If its still producing hot water downstairs can you measure the hot tap flow only, this will help to confirm that its the flow switch problem.

Did we rule out a passing mixer? My money is still on that.

As boiler is really a logic maybe flow turbine and or sensor?

Quick update,

just had a guy out he says it’s a passing mixer something about water just keeps going round that’s why it’s going cold so we’ve ordered one he’s told me how to do it so wish me luck
