Ok, if I were to buy an oil filled radiator with a
power output of 2.5kW, but which has heat settings
of 1.1kW / 1.4kW / 2.5kW, does that mean that it
will run at (e.g.) 1.1kWh at the lowest setting,
rather than use 2.5kWh (assuming it's on for an
hour!) or will it use 2.5kWh regardless?
Please would comeone clarify this for me? I know it may be a daft question but I can't afford to pick the wrong heater
