We are looking to replace our existing Worcester combi boiler (about 10 years old) with a newer condenser model. Two of the quotes that we received mentioned that the diameter of our gas pipework may not be sufficient.So my question is: is this correct? Our flat is fairly small (5 radiators) and the existing combi boiler works fine with this pipework, leading me to think that this may be a bit of a con. It wasn't mentioned by any of the other plumbers who quoted us, either.It would be a royal pain to change the pipework, as it is a listed building, and the pipework itself can be no more than 12 years old, as this was when the building was converted to residential dwellings.Thanks,JP
It is seen as good practice to have a combination on a 22mm gas pipe. This is not always necessary but I would recommend it as it can effect boiler performance. British gas used to refuse to take people on to a contract that had 15mm gas supply. Obviously the smaller the input of the boiler the more chance that 15mm will be fine, check the manufacturers instructions for the boile, (avail on line and see what they say)
The condensation pipe runs from the backside of the boiler many times. Disconnect it on the backside of the boiler and positioned a bucket under the pipe to collect the water for the size of the freezing climate, it in simple terms dribbles somewhat and the bucket in simple terms desires emptying each and every few days. (Mine has been working like this quite luckily for each week). whilst it unfreezes of course reconnect the pipework. terrific of success and a happy Christmas, Bob.
Decide what boiler u want then check gas inlet to it All boilers will show that info. on the owners manual if not on it.(Name plate)
