Forgive any mis-use of terminology - I'm no expert on boilers etc. I currently have two gas boilers, both in my kitchen. One gives instantaneous hot water, the other does the central heating only. With a re-fit of the kitchen coming up I am considering replacing these two with a single combi boiler (to save some space), but am unsure of what to get or what is actually available. The few combis that I have seen have a pressurised part (the heating circuit, I presume) but I'm not keen on risking my ageing pipework with one of those - so is it possible to get combis which are un-pressurised? (and what's the advantage of pressurised anyway?) BTW - The only other room which has hot/cold water is the bathroom, which is next to the kitchen, and both are on the ground floor. Therefore I'd rather not go to the hassle of hot-water cylinders etc upstairs.
