We've got a new combi (about 2 weeks old!) my parents have an old one and have to wait quite a while for hot water ours really is nearly instant - certainly no longer to wait than the traditional boiler it replaced we paid for a good one though. The age and type of boiler you have affects how efficient it is, with a modern condensing boiler being the most efficient boiler on the market. Other conditions that can be recorded by the profiler are the size.
