It's out with the old and in with the new. This post is categorised as DIY, but actually a nice chap from Amber Heating and Plumbing is doing the work, which is to take out our old boiler, hot water cylinder and hot and cold header tanks, and replace them with a combi boiler. So once it's done, all our hot water and heating will be on-demand and we free up the space the cylinder and tanks were occupying. We also get rid of the incredibly noisy shower pump which terrorises me in the mornings when my wife gets up.
