Hi All, I have recently moved into a 4 bed house (standard terraced Victorian property with a loft conversion in the Kingston area). There are two showers - one in the loft and one on the first floor and radiators in each room. There is a glow worm boiler in the kitchen (pic 6) which seems to have two valves fitted (pic 7) and an external thermostat (pic 8). There is also a button/panel which sometimes comes on (pic 8) - I am assuming this is an override switch or something. In the loft there is what looks like a megaflow (pic 4) as well as an immersion heater or something (pic 2) and a pump (pic 3) . I don't understand why there are so many boilers and am wondering whether we can lose the setup in the loft as its bloody noisy and takes up a lot of room. I've attached pictures, but if someone can explain why we have so many bits of kit that would be really handy - three plumbers have come out, scratched their heads and gone away again. One plumber came back and said there's nothing that can be done as it will be to do with low water pressure?
