Reviews
A combi boiler is the cheapest replacement method as your conventional system will almost certainly require some expensive alterations to bring it in line with todays Building Regulations which is a mandatory requirement The combi system or any other for that matter would require the valves to be thermostatic on the radiators except one and in that room a room thermostat would have to be fitted(unless of course you already have them). The hot water cylinder will need to be replaced with a high efficiency one and they are several hundred pounds without fitting. As has been stated you will get all the hot water you need at the turn of a tap but do get a good boiler. I personally favour Baxi, Glowworm,Potterton and Worcester Bosch but there are others. Do yourself a big favour and get 3/4 prices inc BG if you wish and you will see a huge price difference between BG and any others although I understand BG are lowering theirs and their systems are no better or worse than any reputable independent installer. Get recommendations from friends if you can rather than just picking from the directory.
