ok.
First thing, remove NRV from expansion pipe. It will do nothing for you and will cause problems if it sticks. I.E it is dangerous and a big no no.
Things to remember are that 1 bar pressure = 10 metre head. How high is F/E tank from top of boiler. this will determine pressure on gauge. On a vented system, you should be getting about 1/2 bar reading on the gauge. Again this depends on position of tank in relation to position of gauge, Don't worry too much about pressure for the moment.
Do you think you have a leak?
If you seal the system, it will only leak faster due to higher pressure.
Try this first.
Tie up ballcock in F/E tank and leave it for a week, observe water level over this time. If it drops alot, then you have a leak.
When I was working on the system, i did it on the fly, the water hit the roof of the shed before i capped it, so may be its the guage.
Ha ha, good man. You know your a pro when you attempt that kind of thing. As my father in law once said "To the uninitiated - a teaspoon of water is Niagara Falls!"
What size is the boiler? Im not sure, its an Italian make that Ive never heard of. I will check it again tomorrow.
The size of the boiler would not cause air to enter system. Have you looked at the automatic air vent? they are cheap and maybe worth replacing. I replaced the old with an automatic on Sunday and its working fine.
is the cold feed tee'd into expansion pipe? I assume not since you put on a NRV. No its not.
woke up this morning feeling blue
looked at the heating dont know what to do.
No water in upstairs rad
tells me system is still bad.
Just had a thought - could the cylinder that I bought,
be leaking inside the coil, causing the water not to boil?
Any advice would be nice!
