Hi All. I have an issue with a boiler in a small flat I purchased that has very old vented system boiler currently fitted.
Both boiler and water tanks are in a need of replacement.
I got 3 quotes from gas safe engineers and all recommended combi boiler to be fitted.
One of the engineers pointed out that the 15mm gas pipe supplying the current boiler is not up to standard with the combi requirement of 22mm.
But replacing the pipe is going to be a mess. It is laid under concrete floor and the meter is in another room. Will have to lay new pipe below the ceiling instead. It’s not going to be visually pleasing and I don’t want to do it. I’m considering going for new system boiler instead.
Engineer suggested that there is a chance new boiler will receive enough gas pressure through existing pipe, to function and meet minimum requirements as this is a small flat without other gas appliances. But there is no way to tell until the boiler is fitted.
If that proved to be the case we would leave 15mm pipe as is and install combi boiler. Otherwise we would have to replace the pipe first.
My question is if that is correct? Is there no way to measure gas pressure without purchasing the boiler?
If the gas pressure was too low and new pipe needed installing I would rather opt for unvented system boiler. Which would be probably much simpler to install and avoid gas pipe going through the living room.
So I wonder if there is a way to tell before purchasing anything, if gas pressure could be estimated/calculated without committing to any work.
And the other question do you think system boiler would be a reasonable option?
Any other advice welcomed!
