回复: 房子取暖是heat pump, 什么意思？有什么利弊？
热汞热水系统(Heat Pump Water Heater)是一种最新的省能源、低维修的供能方式。它的运作像一个冰箱，只不过是反向操作。抽取空气中的热量.....是的，即使是冷空气也存有热量，因此它不受能量转换效率(100%为其极限）的制约。
好处是:
1, 省电。热汞系统平均省电65-80%，比传统电热系统省1/3的能源。能源使用效率高，电费低于电、气、太阳能任一种供热系统。
2, 稳定。因为是主动吸收免费热量，随时可产生热水。
3, 体积小。安装简便，省空间。
4, 安全。热汞使用电力、却不是用电力加热的热水系统。所以电流和用水完全隔离。
5, 无污染，没有环境、健康的疑虑。可供热也可供冷。
缺点是：
1, 当室外温度靠近−18℃ (0ㄈ)且温差很大时,热汞与传统供热系统所消耗的能量，并无轩轾。
2, 同时，过冷水气会凝结在室坏交换器上，系统必须像传统冰箱一样除霜。所以，严寒天气里，热汞取暖还不如一般的电阻加热直接、有效。
另外,楼主买的是地热式房屋吧？

Heat Pump Systems
For climates with moderate heating and cooling needs, heat pumps offer an energy-efficient alternative to furnaces and air conditioners. Like your refrigerator, heat pumps use electricity to move heat from a cool space into a warm, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house; during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide up to 4 times the amount of energy they consume.
The most common type of heat pump is the air-source heat pump, which transfers heat between your house and the outside air. If you heat with electricity, a heat pump can trim the amount of electricity you use for heating by as much as 30%?40%. High-efficiency heat pumps also dehumidify better than standard central air conditioners, resulting in less energy usage and more cooling comfort in summer months. However, the efficiency of most air-source heat pumps as a heat source drops dramatically at low temperatures, generally making them unsuitable for cold climates, although there are systems that can overcome that problem.
For homes without ducts, air-source heat pumps are also available in a ductless version called a mini-split heat pump. In addition, a special type of air-source heat pump called a "reverse cycle chiller" generates hot and cold water rather than air, allowing it to be used with radiant floor heating systems in heating mode.
Higher efficiencies are achieved with geothermal (ground-source or water-source) heat pumps, which transfer heat between your house and the ground or a nearby water source. Although they cost more to install, geothermal heat pumps have low operating costs because they take advantage of relatively constant ground or water temperatures. However, the installation depends on the size of your lot, the subsoil and landscape. Ground-source or water-source heat pumps can be used in more extreme climatic conditions than air-source heat pumps, and customer satisfaction with the systems is very high.
A new type of heat pump for residential systems is the absorption heat pump, also called a gas-fired heat pump. Absorption heat pumps use heat as their energy source, and can be driven with a wide variety of heat sources.
