I am having trouble understanding how these heaters work ? 
They  are coming on but OK but I am on a elec key meter and I am noticing with just one heater on the heater is taking is £3 per day (elec). 
This is too expensive for a one bed flat.
My question is How can I put the heater on for 1 - 2 hours on a evening ?
