no water pressure coming out of the hot taps

[richymac81]

theres a heatline combi boiler and the heating is working but when you turn on a hot tap (any hot tap in house) water comes out for 1 second and dies straight away so theres no water come out at all which in turn means the boiler does not fire up,has any body got an idea wots wronge with it. it had flue sensor and water filter changed ,i was thinking plate to plate exchanger,i would be greatful for any help!!!!!!!!

Howzya cold supply richymac81? Is the iso valve to the boiler turned on fully? Do you live in a hard water area, had any work done on the mains in the street recently? When you mention having the water filter changed, was this the inline filter on the boiler & if so was there much muck in it? Answer these will eliminate or help us help you a bit more

hello cold supply ok ,and iso valve fully open,it is a hard water area!!! and mains are fine well so servern trent says,and yes the inlet filter on boiler was changed but i didnt change it so i dont no how much muck was in it?????????

 

[mcniven]

is ure cold supply at taps good yeah

 

[richymac81]

no hot water pressure from taps but cold pressure fine ,the heatline a sealed combination system

 

[mcniven]

we know its sealed mate!

i reckon its a filter thats choked, cold inlet to boiler!!!

 

[mcniven]

but then again................... im an installer and dont fault find ????!!! :rolleyes2:

 

[richymac81]

yeah fine ,thinking plate to plate blocked full limescale

Hey you returned :welcome: back

How old is the boiler? Chance it may be scale build up if you haven't an inline scale reducer and you're in a hard water area? Just a thought! However it isn't really rocket science if all are affected then the blockage is traceable down stream from the first tee after the boiler.

 

[diamondgas]

yeah fine ,thinking plate to plate blocked full limescale

It's most deffo possible but should have shown it's face long before now IMHO

 

[spanner]

rich, if plate to plate is blocked, would this stifle water fully?? Just that I'm a bit lost....:drunk:

 

[glenno1]

turn off cold supply at boiler,disconnect hot pipe then turn cold on slowly see what sort of pressure is there be ready with bucket and soak ups
