My problem is that i can't get enough hot water from my oil fired combi boiler to fill even a small bath. The tap will run hot for a couple of minutes ok but then turns cold and i have to leave it for five minutes before doing the same again. By the time the bath is filled most of the water is pretty cold and therefore useless. Unfortunately i live in a rural area and there is no gas supply so im really stuck with the oil boiler.
Any help anyone could give me on this would be much appreciated
