First of all they're shit obviously, but we've just turned our on yesterday - our house is freaking cold I could see my breath when I woke up yesterday.

Anywho the heaters went on and as they should they stored the heat overnight. The output is on the lowest setting and the heater is very hot this morning.....I want to know, will the heat be there for me this evening when I need it? ie will it not have been released or lost?

So basically how long can they hold onto their heat for?

Bloody stupid heating system!
