Heater Thermostat Setting
Don't turn the thermostat to the hottest setting to make your heater heat faster.
All you are doing is changing the final 'off' temperature.
It won't change the speed at which the heater operates. Setting the thermostat hotter won't make the room heat up any faster.
Just set the dial to the temperature that you want and let the heater do its job.
Setting the thermostat hotter forces the heater to over-heat the room which just wastes energy.
