1. Achieve zero cost of hot water, photovoltaic heat pump is 80% more energy efficient than air energy heat pumps. 2. Remote intelligent control enables cloud operation. 3. No need to frost, no worry about low temperature and humid climate. The outdoor heat exchanger and piping of PV heat pump are circulated with superconducting liquid, which will not freeze above -45C, so there is no need for defrosting at low temperature, no freezing safety hazard, ensuring continuous heating, and higher overall energy efficiency. 4.-35℃to 48℃ wide operating range, ensuring stable temperature output in winter. 5. Innovative design of multi-energy heat exchanger. After years of field testing, design and manufacture of unique N-shaped structure of the multi-energy heat exchanger fins, to strengthen the heat absorption at the same time, to extend the applicable life, no fear of harsh outdoor environments, maintenance is more convenient. 6. Low noise fan, closed space sound insulation. 7. Widely used in hotels, factories, schools and other commercial hot water. OEM/ODM Services Available.
