Hi I'm plumbing in a rayburn solid fuel range in our renovated
farmhouse which is "1.5 story" high. Instead of having the cylinder
directly underneath the exp and feed tanks, in the centre of the
upstairs room above the range, would there be any reason not to place
it towards the eves, ie off centre and have the exp pipe running at an
angle approx 40deg about 2mtrs to the exp tank in the apex of the
ceiling.

The thing is to keep your pipe runs as short as possible, especially
between the taps and the cylinder. Why not put in a mains pressure
tank you won't need expension tanks?
