No running Hot Water

[Owenstack]

Hi I've just returned from holidays and have no running hot water (no water at all from hot tap) everything was working fine before we left so I'm a bit puzzled, nothing has been turned off to cause this?
We have a Valliant Eco Plus 824 Combi Boiler but it's heating the Rads fine??
Any suggestions?

Are you sure the heating is working. As a loss of water pressure would stop boiler firing up.

is any water at all coming out of any hot taps ,or are all of them giving nothing. and are cold taps giving water ?

only a drop in pressure in the sealed radiator system can prevent boiler from firing .

Cold water is running but to be honest it does seem to have lost a bit of water pressure! Heating is working ok

 

[terryplumb]

what about my questions re hot ??

 

[Owenstack]

No nothing from hot tap at all on any floor?

 

[terryplumb]

so if your hot water is coming directly from your combi boiler ( no hot water tanks ), then the cold feed going into the boiler has been isolated or there is a blockage inside the boiler ( most likely a filter ). you said the cold water seems to have less pressure , is it possible that water supply's have been worked on in street while you were away ? ask neighbours ,or water supplier.

If water pressure has changed would that effect the combi boiler?

 

[terryplumb]

it would affect the flow coming out hot taps. it would not result in no water at all coming out. and your c/heating will still work as the water is sealed in the radiator circuit and just gets pumped around and thru the boiler. the reason I ask about work in street , is because if water to you has been shut off whilst emergency or maintenance has been carried out on mains , sediment can come thru when put back on ,and this can block filters .

Thanks for that Terry I'll check it out

did you turn your stop tap off before you went away ?

how much cold water flow have you got ?

Turn filling loop valve off.

 

[Owenstack]

Never touched anything? Seems to be ok running ok in the sink and bath upstairs? But nothing from hot taps?

 

[Steelmasons]

As I said , check fill valve is OFF...the grey knob under boiler.
