Our boiler (standard gas with hot water tank) was in the house when we moved in 23 years ago, I reckon it's 30+ years old so we're planning on replacing it this summer. Obviously, a new one will be much more efficient anyway but I'm wondering whether to change it for a combi one, are they as reliable as standard ones and are they that much more efficient?
