i'm alone in a flat of 4 for this week, its bloody freezing and normally we'd get heat from the flat above and below but it looks like they're both empty too. i have an electric 2kw heater, which i run on 1kw.
is it cheaper to run the boiler having turned off half the heaters in the flat, or should i just use the electric heater? i have no idea what the power consumption of the boiler is, and the timer on it is broken so it's either on or off or on for a x of time.
i know how to work out cost using numbers, but the question is how much does the boiler use really
