Combi boiler, is this normal?

 

[ShaunCorbs]

Yep gues it a combination of low mains pressure and a low kw boiler eg 24kw

 

[Harvest Fields]

Yes mate it is. What boiler do you have?

 

[king of pipes]

It will only supply one outlet at a time i am afraid . kop

 

[S.P.S.]

Especially if either the filter is blocked or your plate is furred up....!
