I'm considering an extension and at same time fitting gas central heating (not me fitting the gas of course). Everything is variable including boiler position and flue.
Is it better to have the flue exiting from the roof? Or is a wall exit just as good for the risk of nuisance? I could have longer horizontal flue inside (does that help remove condensate?). Or I could go vertical but that would be from ground floor (probably) so access panels and inspection is then a pain. Or I could go through downstairs wall then have a bit of vertical flue management pipe, or I guess a bit of vertical flue. It's on a don't care about side of the house when the bins are stored. It's a 2m wide access way that faces next door (and next door's flue).
TIA
