No hot water upstairs

[Liamc94]

Can you get to valves on the kitchen tap? Turn off the cold and see if that changes anything.

There’s a tap under the sink in the kitchen but Iv no idea what that does sorry I have no clue what I’m doing so if it sounds stupid I apologise!

You are getting hot water downstairs with a hot tap only opened but not upstairs with a hot tap only opened, if the hot tap flow upstairs for whatever reason is less than 2.5 to 3 LPM then a flow switch in the combi will stop it firing, see how long it takes to fill a 1 litre jug/bottle.

It’s filling a 1L bottle in 0.8.36?

Was that upstairs at the basin?

Can you post a pic of the valves under your kitchen sink?

Upstairs sink mate yes,

Iv just discovered if you put the heating on while running upstairs tap and shower it works fine? Or I may be coincidence but it wasn’t working 2 minute before I tried that

Switch off the C heating but leave both the hot tap and the shower on and see if water still hot, the tap alone at > 7 LPM should keep the flow switch very happy but it may be faulty, also measure the hot tap flow rate downstairs only but all upstairs shut down.

No mates it’s not hot now Iv turned it off

 

[John.g]

So no hot water upstairs with hot tap and shower on but C.heating off, is downstairs still hot on its own?. (also flowrate)

 

[Liamc94]

I’ll get flow rate in morning bud,

yes hot water down is fine with out central heating. But Iv been told to put the heating on for 20 min and check all radiators and one in my boys bedroom upstairs doesn’t get hot.

i went to turn it off and thought I’d check pressure first, it was on 2 and the needle was shaking all over as soon as I turned dial to turn heating off it went straight back down to 1.5?
