● Green and Environmental Protection By using air energy and electric energy, there is no harmful gas being discharged during the work of heat pump. R134A refrigerant guarantees fluoride-free emission.  ● High outlet water temp. A regular heat pump therefore takes longer than a boiler to heat your home, meaning you need larger radiators to ensure it won’t take forever, and insulation to stop heat from escaping during this process. High temperature heat pumps can output max 80C high water temp , and it can operate at the same heating level as gas boilers, meaning you can replace one with the other without having to get new radiators or insulation.  ● Durable & Stable Running at -25℃ Ambient Temp Thanks to the The Enhanced Vapor Injection (EVI) technology from Copeland compressor and other brand components of the heat pump, the unit could be stable running at -25℃ Ambient Temperature guarantee high quality and a long lifespan. And all of our screws and clips (both external and internal) are stainless steel. The cabinet we are using is made of  galvanized steel, making them more rust resistant and durable.   ● Smart Defrost Technology Intelligent defrost technology to reduce the defrosting times and thus extend the unit heating time. Rapid defrost to shorten defrost time can help to recover supply water temperature quickly, improve the unit heating efficiency and maintain comfort.  ● Wide Application High temperature heat pumps can be very efficient for hot water production and have been adopted in commercial settings for hotels and restaurants where there is high hot water demand. The unit can be used in industrial applications such as electrioplating factory, food disinfection or drying. laundry etc. And it can also be used in hotels for hot water supply with a smaller tank.  ● Multiple Protections For example, if water flow is not enough in the system, the system will show high pressure protection and stop the heat pump automatically to protect the compressor from being damaged. Also, there is high current protection: if the power supply is not stable, the heat pump will show the high current error to stop the heat pump and avoid compressor damage  ● Quality-guranteed Components Use international famous brand components equipping  Model BLH36-038S Rated heating capacity kw 18 BTU/H 61200 COP w/w 4  Heating power input kw 4.5 Fan power input w 360 Max outlet water temp ℃ 85 Applicable ambient temp ° C -25~43 Water flow volume M3/H 3.1 Water pressure drop kPa 60 Compressor Copeland Scroll Fan direction Horizontal Fan speed RPM 750 Noise level dB(A) 56 Water connections Inch 1"  Net dimension       （LxWxH） mm 1115*470*1250  Packing dimension （LxWxH） mm 1220*490*1400 Net weight KG 154 Gross weight KG 174 Power supply V/Ph/Hz 380/3/60 FAQ 1.Where can heat pump units be used? Heat pump units are widely used, including various types of commercial machines specially designed for hotels, schools, hospitals, saunas, beauty salons, swimming pools, laundry rooms, etc.; there are also various types of household machines specially designed for families.  At the same time, it can also provide free air cooling, which can realize the whole year heating. 2.If there is any problems of the heat pump in the future, how to fix it? We do have unique bar code number for each unit. In case heat pump has any problems, you can describe more details to us together with the bar code number. Then we can trace the record and our technician colleagues will discuss how to solve the problem and update to  you.
