Reading the other thread with interest as I have a similar question. We're looking at changing our heating system completely as it's 20+ years old and the radiators are pretty ripe, the hot water cyl leaks and despite being a small house the boiler burns more fuel than the Argentine navy with a nuclear sub on their tail.
All heating here is oil fired and due to the nature of our water supply a combi is not an option, so it will be a balanced flue oil-fired boiler feeding radiators and a conventional hot water cylinder with a gravity feed cold water system.
Options locally are a Worcester Bosch Camray Utility condensing boiler, or a Mistral CKUT3 condensing boiler, similar thing, different manufacturer.
So, any views on which would be the better product? Both have decent parts backup and support, and no other makes do here, so any alternatives are unlikely to be worth considering.
Our heating bill is about £2500 a year so I think I'm prepared to pay the extra for a condensing model -the WB supplier also has non condensing models available and they are cheaper, but 10% fuel saving will cover the cost difference in a couple of years.
