With the advanced DC inverter technology, E.S. Nord DC inverter air to water heat pump can save you 65% heating cost compare with the traditional heating device like gas/fuel boiler and electrical heater. It works perfectly with the radiator and floor heater to provide you a comfortable living environment even in very cold winter. It is one of the best heating devices available today.
KEY FEATURES:
* Twin rotary compressor with inverter control – DC inverter technology control the heat pump output according to the household’s energy requirements. Low waste of the power
* Economical and high efficiency – advanced heat pump technology can reduce your heating costs by 65% compare with the traditional heating elements
* R410a refrigerant, environmentally friendly – Green energy, no CO2emissions
* Advanced controlling – it is extremely easy to control the heat pump because of the intelligent controller and LCD displaying.
* Safe operation with multi-protections – Overheating protection, high compressor discharge pressure, high compressor temperature, low pressure protection… make the unit running safely.
* Electronic Expansion Value allows the accurate refrigerant go through under different working conditions. So it ensures that the E.S. Nord heat pump can work with high efficiency to provide enough cooling/heating capacity in any conditions.
* Hydrophilic coating air exchanger and SWEP plate heat exchanger
* 4-way valve to ensure reliable defrosting function
* Wilo water circulation pump
* Relatively low initial investment, easy and convenient for installation and maintenance
OPTIONAL:
* Galvanized metal cabinet or stainless steel cabinet
