Didn't realise how expensive these things are ($200nzd each for a 400w panel), i have changed my mind now and will not be buying them. Each of them work the same as a normal electric convection heater (u get close to 100% efficiency i.e. $1 or $1 worth of heat), saying that, you would potentially be better off buying a $100 oil column heater that can output 2000w of heat though (i.e. you need 5 of these panels which will cost you $1000 to buy to produce the same amount of heat).
Most people seems to buy these panel to leave it running 24x7, if you own your current place and are looking for a primary heat source that you can leave running all the time, get a heat pump, each $1 will give you about $4 worth of heat. |
