Do I need a bypass circuit for my central heating system?
carloshenderson asked:
British Gas just came round and replaced the valve in my heating system as it was getting stuck either on or off so not responding properly to the system controls - that seems to have fixed the issue.

However, they’ve recommended I get them to install a bypass circuit in the loft as there isn’t one there at the moment. They said without it the boiler can overheat, and therefore need resetting, as there is nowhere for the water to be pumped when the system shuts down but the pump keeps pumping for 5 minutes. They quoted £225 for the job - does anyone know if I actually need this?
Thanks for your help

An expansion tank built in so the bypass would be the bypass would be the bypass would be the equivalent of back up to back up to back up to back up to back up to back up to back up to back up.
