I have a Vokera combi boiler (excell SP 80) which is probably around 12 years old. Lately is has switched off for no apparent reason. Even though I have managed to switch it back on, what would you recommend to do : have it repaired or changed?Other question, when I asked for quotes to have it changed, the plumber told me that the gas pipe is too narrow and the gas pipes leading to the boiler need to be changed. This would entail major work, so my question is : shy should I have wider gas pipes fitted?Thanks in advance for all your answers
Newer boiler would be more efficient. I would get another bid though. wider gas lines? That sounds fishy. The gas supply line should be fine unless you increase the BTU's . But even then it should be fine.
