1) how long is a piece of string...? Depends what you want it to heat and how you want it to do it. I would budget at least 2 grand, particularly as a 17 year old boiler may come with added things that need to be done to radiators and electricity.
2) Noticeably, though I wouldn't expect it to pay for itself, specially on relatively cheap mains gas.
And I will add:
3) Don't buy a sodding Keston
4) buy a boiler only from a well established local business that is as committed to servicing that brand as it is to supplying it.
1. Depends on the boiler. 2. Very - when it works. But modern boilers have wonderful all-singing motherboards which die regularly, costing unbelievable sums to replace.
Our boiler needs not only replacing (it was installed when the house was built in '67), but moving from the kitchen to the garage. This is going to cost something in excess of £2500. Sans fitting. Yours should be a lot cheaper (if that's any consolation).
1) depends what you have now and what you want to replace it with. If you have a boiler + hot water tank and want to keep it that way, the new boiler will cost less than if you do away with the hot water tank as well (which is what we did) and get a combi boiler. I would also reccommend going on some online forums to ask about god makes of boiler. We got a Worcester which is top of the line and it hasn't had a single problem in nearly 4 years. At the same time, we had the whole central heating system powerflushed to get rid of years of accumulated sludge and had TRVs (thermostatic radiator valves) fitted to all the radiators. All in it cost us £2700
2) It will be hugely more efficient as all new boilers installed nowadays have to be condensing boilers. These are somewhere in the region of 95-98% efficient compared to 70-80% efficient for conventional boilers. Mind you, you should also look at whether your loft lagging is up to scratch (you can get grants from councils for replacing it) and whether you have cavity wall insulation and how good your windws are. You might be better spending the money on stopping heat from pouring out of your house.
The other important factor to bear in mind is that finding spares to fix a 17 year old boiler if it packs up could be tricky, meaning you have to get it replaced anyway. When we moved into our house, we got a heating egineer to look at it and he said it was fine but if it packed up it wasn't going to be economically repairable. And I have to say the central heating is much better with the new boiler and TRVs
