How to use solar heating? A reasonable solution?
Air energy manufacturers have grown from 216 in 2008 to today's 461. As for what brand is not important, it is important to look at a few key data: 1, whether it is true air energy (source)? The real air can be without any electric heating auxiliary, in winter, 15 degrees below zero can also be normal start and COP value of more than 1.6, if the electric heating that becomes a high price electric boiler. 2, the average annual energy efficiency ratio (COP) is how much? Generally should be around 4.8. 3, is the air conditioner to change? Air conditioner can not only the transformation of the air below 5 degrees can not normally start and electricity heating, it can not be normal when the ambient temperature is above 40 degrees, but also to use electric heating. 4, the real air in the production of hot water to reach 50 degrees when the system pressure is not more than 22 kg. If exceeded, the equipment often work under high temperature and pressure environment will seriously affect its service life.
Solar water heater is water storage, only a bucket of water, a circle of no temperature. The rest is electrically heated! Solar energy is just a gimmick. I used to do solar energy, and now has not done, it should be able to do the air, but also to warm up, but also with hot water, kill two birds with one stone
Air energy heat pump water heater industry pioneer in the careful cultivation has been gradually recognized by the majority of consumers. Her advanced nature lies in the very energy saving and environmental protection, with other water heater can not be replaced.
