Just moving into a 2 bedroom house with centra; wet heating. The scheme has no gas. in the kitchen there is a big indirect cylinder (water tank)an a combi boiler at the other side. takes a lot of space up in the kitchen a its in a big cupboard. can anybody tell me if I can remove it? is it off use? do I need it? and if I do whats the estimate to move to loft if it is possible is it hard? thanks
