Hello, I would welcome any advice to a complete novice about my old glow worm 45-60 boiler. I have an immersion heater in the loft, along with a cold water tank. The boiler must be very old, as it was in the house when I moved in 24 years ago, it is still working (touch wood). People are beginning to frighten me about it, telling me to get a new one and that I am wasting so much money with this old one. Can anyone tell me what kind of boiler it is? I realise it is not one of the new combi boilers, what is it classed as? If I had to have it replaced, I am frightened about all the new rules, I would just like the old one out and a new one in, like for like, I really don't want lots of upheaval, can it be straightforward? The timer which is situated just above it is supoosed to work on timed or you are supposed to be able to have water only, I cannot remember it ever working on water only. Should it? and would it be worth getting a new one fitted? I don't know whether to stick with it or think about replacing it, any advice would be most welcome.
