I'm using the Carrier heat pump, electrical furnace with Infinity control system. This combo is much better than my old oil heating system. But the installation is very expensive. % N: T" j$ h% J4 j' b3 z/ t! Z; o * P6 T8 ?/ f/ k* t3 Q8 i9 EIn theory, the heat pump can produce heating when the temperature is above -12 degrees. Actually, Its efficiency is very low as long as the temperature is below around -5 degrees. I let the control system to switch between the furnace and heat pump. It does a good job.$ L+ @ v5 y6 D% F% k ?3 w

如果HEATPUMP -5就工作不好的话,是不是没有什么必要加了?$ w W& l2 k5 d0 K5 Y. C
只加中央空调是不是比HEAT PUMP就制冷方面要好呢? + i; m: i) e- i4 ?! d* T( u+ @还是说建议一步到位HEAT PUMP,而不要中央空调呢?:confused:
+ Q; L" t1 ~9 ]) J. `9 _) J我不太懂您所说的中央空调指的是什么。应该就是我所说的HEAT PUMP吧。HEAT PUMP既能制冷又能制热。夏天用它COOLING, 冬天HEATING。 但毕竟HEAT PUMP工作是有温度限制的。温度越低效率越低。所以一般要让它和其它的取暖设备协调工作。 # D! K |/ \. h }4 H, B+ q ! L& h2 C& I' B; R5 S
你可以用HEAT PUMP 和OIL HEATING 或者GAS HEATING FURNACE组成BIENERGY。这样的话您可以和HYDRO QUEBEC签协议。在-12度以上用电半价,-12度以下用电双倍价格。6 [0 Q3 W$ |: c- G4 Z5 ?

当然您也可以像我这样让HEAT PUMP 和ELECTRICAL FAN COIL(电炉子)一起工作。2 p! k, A. _: P& U0 g% _# C( f; l" O! k
