where will i find the pressure guage, never seen it before?

normally on the boiler

make / model might be an idea

 

[gunthos]

sorry its a micron glow worm. not sure of the exact model, there is no pilot light just a knob on the front with min/max and a light for reset and a light for burner

 

[kevplumb]

ok why do you think its on a sealed system

glow-worm micron can be fitted sealed or vented

do you have two tanks in the loft

why do you think it needs checking

 

[gunthos]

it appears i am on an open vented system

there is one tank in the loft with cold water and a tank in the airing cupboard. the reset light is shining solid green on the boiler, i am trying to figure out why.

i took a radiator off recently and drained the system, since then the boiler started to work but then turned itself off and now does not fire up at all

thanks for your help, however i have already tried turning the knob to zero and re firing the boiler and it still would not work

 

[kevplumb]

ok what is happening

what sort of system do you have

is the pump running

 

[gunthos]

it is an open vented system

i took a radiator off and drained the system, since i turned the water back on the boiler does not work

inside the airing cupboard where the hot water cylinder is housed is making noises as it normally does when working correctly, pump also appears to be working

reset light is shining on boiler and it will not fire up

 

[kevplumb]

check the tank for the heating usually the smaller

has it got water in it

 

[gunthos]

how can you check if it has water in it?

is there a way of looking inside it?
