So how does a slow heater make any difference.

By putting heat into the house whether it needs heat or not.

Is this what you have along with your auto bedroom lights than turn on when you go to bed ?



Take the kettle if it takes longer to boil the water surely you have
probably used the same power as you would have with a more powerful heater
for a shorter time.

Yes.

So less efficient .


Same goes for room heaters.

Nope, not if it adds heat when the room doesnt need it.

why would it do that ?
