Bath water not hot enough

[ashtonjay]

My customer has a Valliant bolier and his bath tap water isnt as hot as the hot in the kitchen sink
the boiler is upstairs in the bedroom next to the bathroom too
how can he balance the hot water temperature?

cheers

Your customer?

This is the most basic of basics.

Higher flow rate through bath taps is too much for boiler.

Is it through a mixer valve? Might be due to unbalanced hot/cold pressures

Tb is almost certainly right, though there is a possibility a tmv is fitted to the bath Hw supply if a newish install

 

[ashtonjay]

There is defiantly no tmv of any sort fitted as I fitted his bathroom
I stay away from boilers completely and mainly tile and fit bathrooms
Personally I think the water is hot enough but his missis loves very hot baths (she pours kettles of water in apparently
I told hi. There are certain criteria regarding the temp of hot water

As tbservices said then

22mm on bath from combi tut tut

if the bath is cast iron then this might be an issue as well:thinking:

Don't run the hot tap on full. Run it half open. It'll be boiling. Might take longer but much hotter. Simples.
