Gas pipe to new boiler

Anonymous user 09/11/2026 - 1.48 PM

I am confused? I have had 4 quotes for a new combi boiler. Two of the quotes say I new a pipe upgrade and Two say I don't? My boiler is in an off shot galley kitchen (next to a normal gas cooker). The floor distance from the meter (in the cellar) is approx 10/ 11mts. There are a couple of bends that take the pipe from the cellar to the kitchen. The pipe is 22mm all the way. I have looked at a 24kw Ideal basic Boiler and a 30kw Ideal Logic Max. Which company should I believe?

Based on what you are saying with the 24kw boiler you should be fine providing that it is 22mm all the way. The 30kw however there is a chance that the first section may need upgrading to 28mm there are calculations we can do to work this all out pre install. If there is clear access to the first section in the cellar though the upgrade should be fairly easy.
