My current CH-HW system is 10 years old. The boiler works fine but the pipes and radiators are full of muck. The boiler is in a daft place in the kitchen (soon to be refitted), occupying much needed wall space. The house is a 3 bed semi with 10 radiators, 1 bath, 2 showers, 4 sinks with HW taps and a HW cylinder.
1) I'm thinking about replacing it with a combi to free up a bit more space (i.e. cylinder and tanks). I've heard some negative reports about combis e.g. taking ages to fill baths, showers not working well (my showers are not powered in any way), reliability concerns ... Should I be concerned about a combi?
2) With a combi, as you are not heating a couple of hundred litres of water for your cylinder, is there a noticeable reduction in gas bills?
3) Is there any reason why a boiler (combi or standard) should not be sited in the loft?
4) How big a job is replacing the boiler with a combi likely to be?
Thanks in advance.
