说实话楼盖的挺高了,就是没有人正儿八经回答我的问题。回到最初的问题。我只用电,大约2300尺的房子,如果每天晚上7:00到早上8点开,其他时间根据气温开或不开一个月电费大约多少?如果装那个HEAT PUMP,大约费用多 ...
I can answer the heat pump part.....
2300 sqft...u need a 3 - 3.5 ton hp (not sure if u need a new furnace. if ur furnace is old, most likely u need a new one for compatibility and efficiency)
cost is about 6k - 8k. 8k for local company to serve u as a package and much lower if u do enuf research and DIY a lot
i would do 50% of ur winter hydro/gas bill as the monthly cost of heat pump.. you can always spend 150 bux to get an energy expert to tell you how much exactly u could save (it is also required to apply for heap pump government rebate)
once again, im not advertising for anyone. i just post my experience and research.. do not bother to argue like warranty terms ...etc..... with me.
the more you know, you more you save, the better you get prepared for the rainy days
