Length of pipe work to cylinder a waste of energy?
I am considering either an oil or gas bolier to a Heatrea Sadia cylinder in a direct, unvented plumbing system. If I use oil the burner will be in the garage which will be approx 30m away from the cylinder in the house. If I use gas the boiler can be in the same area as the cylinder within the house. Am I wasting energy and money in the 30m of pipe in the oil option? Would I be wasting the equivalent of 3 radiators before I get to the house? Alternatively I could site the oil burner closer to the house since many of them come with weather proof housings these days though this would spoil the look of my propsed patio area!
