Hi,
This looked easy when I started but it has turned into a bit of a nightmare.
Having gutted my house I have replumbed it all and everything is working great except the back boiler on my solid fuel stove.
Having let water into the system I light the fire. The boiler on the back hisses (like an electric kettle) then once it's built up a head of steam blows straight out the vent into the header tank for a about a minute and will keep doing this every 20mins or so. The hissing tells me there must be a fair bit of air in the boiler which I guess is being blasted out the vent when it reaches pressure. I ran it for about 2 hours over the weekend thinking that once it has blown all the air out it will start to work as normal. But it just keeps boiling.
I have the vent placed before the intake into the cylinder coil, is this right? Also the feed from the header tank enters the heating system on the return to the fire.
The hot water from the fire also trys to go up the return pipe telling me either gravity isn't working or I've done something wrong.
Any help very very gratefully received
Cheers
