I am sure your boiler has a way of switching off on demand water

It's a combi, *hours* to heat it's internal heat exchanger or even
built in small buffer store? A decent gas boiler ought to be able to
reheat a whole hot water cylinder in an less than an hour.
Mine doesn't have buffer store nor a hot water cylinder.
When I had a 2 bed flat the HW cylinder would reheat in 20 mins. When
the time switch died, I didn't bother replacing it, just switched the
water on when I needed it. Heating was on a room thermostat and
manual on/off switch. BIG drop in gas bill...
