Expansion Joints on Central Heating system.

[jakelepeg]

I have a long run of 22mm pipe (approx 25 metres) and expansion is creating a problem by pulling pipe clips from wall (wall is very old and constructed of mud brick). Is there such a thing as expansion joints available and, if so, at what lengths should they be fitted. any assistance greatly appreciated.

yes of the slip ring or bellows type unless you want to start bending expansion loops
