Solar as a renewable energy, could heat water without electricity under the rich sunshine, which is high energy-saving.But without the sunshine and in the rainy day,the solar will expose its disadvantage. While heat pump will not be limited by the wheather eventhough it consumes a little bit electricity. No matter in cloudy,rainy day, as long as there is air, there is water. It is no doubt that heat pump is the best fourth generation water heater.
Solar and heat pump both has their own features, if they can combine together that would effect the best advantage. For example, under the sunshine, the solar heater could be used for absorbing the heat and supplying hot water. Under the rainy day, the heat pump could be used as the main heater to absorbing the heat from the air. The two heater as the supplement of each other, not only could offer the hot water in 24 hours but also save energy and eco-friendly.
So how is the reality application? For this problem, Wotech has made a lot of successful project with solar and heat pump combination, which are widely applied in the hotel, school, hospital etc.and get an outstanding energy-saving effect. For example, in YunNan province, there is a project adopted a combination of 50 solar tubes and 4 heat pumps, which could offer 50 tons water everyday.For more welcome to visit us on www.ecowotech.com
