Are combi boilers generally only suitable for flats or smaller houses? I have lived in a number of flats and I like the convenience and efficiency of combi boilers, but looking at houses recently most seem to use a combination of a back boiler and immersion tank (a system I'm unfamiliar with).
Would you say that as a rule changing to a combi is always better, or is the back boiler system better for larger homes?
