i have a knacked combi boiler and i'm looking at replacing it but whats best a combi boiler or a condensing boiler and why ?

go for a worcester greenstar junior or cdi condensing combi, bit more expensive than some makes but very reliable, you'll get what you pay for. the worcester website can help you choose depending on house size, but the more powerful the boiler the better the water output as sean said.

combi boilers are condensing and go for 28kw or bigger as water is better, they're more energy efficient
