I am considering replacing my Glow Worm boiler with a condensing one. My new bathroom is connected to a 3-bar pump so I know I can’t have a combi boiler. I understand that my current boiler is probably at least 30 years old. Will I be able to use the existing pipe work or will this need to be replaced? Or, is there a boiler that is compatible with the existing system? I have a 3-bedroom semi-detached house.
You should be able to use the pipework for your hot water but the central heating circuits will need to be connected via a divertor valve to the hot water circuits making the system fully pumped. You will be able to have any 30kw+ boiler installed to your system.
British Gas are able to send a heating advisor to your home to review the installation options and help to select the right boiler for your home. This visit is free with no-obligations on your part and will also enable an accurate quotation to be developed for a new boiler.
We have a 4bed semi detached house with 2 bathrooms. Currently we have very old boiler with single pipe central heating system. Since we have just done the decorative work we do not want change the pipes. So colud you please let me know that which system will suit our home to run on the current single pipe system?
Thanks
No condensing boiler will run efficiently on a one pipe system as it affects the flow rates, causes nuisance shut down on the boiler and the system cannot be fully flushed so this can also cause corrosive issues in the heat exchanger.
