Hi
My question concerns the flow and return from a clip in boiler on a multifuel stove in a gravity fed system. I am aware that the pipes must be verticle from the stove and that is not a problem as far as the ceiling, but the hot water cylinder is not directly above the stove so there will be a requirement for the pipes to run horizontally for some of the distance when they reach the ceiling. Is it ok for pipes to run in this way without a pump. Thank you. David
