不要以为大别墅的能源费就一定贵,现在别墅里用太阳能、地源热泵的人不在少数。往大了说是节约地球资源,往小了说,也是为自个儿省钱。当然如果你没选好设备,或者找的服务商不够专业,那都是白搭。 Do not think that the energy costs of the villa must be expensive, and now the villa with solar energy, ground source heat pump is a rare person. Bigger to say is to save the Earth's resources, to small to say, but also save money for themselves. Of course, if you do not choose a good device, or find the service provider is not professional enough, it is all right.
