expansion vessel positioning
Hi
I am increasing the size of my heating system (loft convertion) and need to add another expansion vessel ( already 1 in the combi) I've managed to size the vessel requird but can't seem to get to the bottom of where to position it. I have been told that it needs to be as close to the boiler as possible but this is not easy for me space wise - it would be far easier to position it in the new upstairs. If it does need to be close to the boiler could someone explain why - i can't see the difference. Also should it be in the flow or return ( the 1 in the boiler is just straight off the tank) Any help would be gratefully received! Thanks |

Thanks guys!
theres plenty of space in the eaves just where the pipes go down to the original system so I'll put it in the return there. Thats a relief - I had nightmares trying to work out how to get it close to the boiler when the boiler is fitted tightly into a kitchen cupboard! One thing I forgot - I take it it is just teed into the return pipe? Thanks again |

One thing I forgot - I take it it is just teed into the return pipe? Yes. I might include an isolation valve so you could change it in the future without draining everything down (although I didn't think of that when I fitted mine;-). If you're shoving it in the loft, I would put it under the loft insulation so it isn't likely to freeze, although you don't want it hidden either. -- Andrew Gabriel |
