Is it an escape pod from Red Dwarf? No, this is what a hot tank looks like nowadays. It was installed in the corner of the old kitchen. It is super insulated and is surrounded by all sorts of electrical gear. While it gave us lots of very hot water, unfortunately the system soon stopped heating the radiators. The plumber blamed a wiring error. It seems that the electricians had wired the hot water controls to the heating and vice versa..
