I wonder if somebody can answer some Noddy questions about oil fired boilers, please ?
I've got an extremely old oil-fired balanced flue boiler that is becoming somewhat unreliable and a little smelly and I'm looking to replace it but I'm a little confused about the range on offer.
I don't believe a combination boiler is a good idea for me as my water supply can be erratic due to living in the sticks and it's nice to know that I have a tank of water available to tide me over until the supply is back on, but even removing them from the equation leaves me with a lot of questions:
1) What is a condensing boiler ? (AFAICS it's just a more efficient version ?) 2) What is the difference between a "kitchen" and "utility" model ? 3) What are the pros and cons of floor mounted, wall mounted or externally mounted boilers ? (my oil tank is actually about a metre above the kitchen floor so I'm tempted by a wall/externally mounted version) 4) Are there any makes to go for or avoid ? 5) If at all possible I'd like to put a worktop over the boiler and maybe totally enclose it. Do any modern boilers require access from above during servicing and repair (as my current one does) ? 6) Are there any limitations (as there are for Gas) about who can or cannot install an oil-fired boiler (some of the stuff I've read about the new building regs seems to imply that I can't do it myself which I find hard to believe)?
Thanks in advance for any help,
