Pros and cons of combi boilers?

news · 2005-10-10T08:34:12+00:00

I am in the process of getting quotes for supplying and fitting a new central heating boiler. We live in a largeish 4-bed detached house (i.e. not a one-bed flat) with 14 radiators in all.I know that I have to have a condensing boiler (none of the legal letouts apply), but I am unsure about whether to have a conventional condensing boiler or a combi.Can anyone summarise the pros and cons of combis, or point me to sites that may help. One supplier insists I should go combi, another says conventional.Assume that I know next to nothing about central heating.I'm interested in the practicalities of the different types of boiler, not the theoretical aspects. For example, for combi/conventional:1. What kind of servicing/maintenance/supervision is required throughout the year? (E.g. top-up, pressure check) -- with my present old clunker of a boiler, I don't think about it from one year's end to the next, except for the annual "service".2. What do I do if the radiators go cold at the top (should this ever happen in a sealed system?)3. If the boiler is installed in the loft, must I have a permanent ladder/steps, and electric lighting in the loft?4. What happens if the incoming water pressure drops?5. How do running costs compare?6. Is there anything else I should know about?
