Sundez 2013 new brine to water heat pump allows you to combine a water based heating system with a modern heat producing device. It saves energy consumption up to 80% compared with electric heaters.
The ultra quiet design makes the whole compressor and heat pump system on a floating plate, leads to a compete isolation from the heat pump bottom, and reduce vibration and noise at the most extent. That is to say, Sundez new brine to water heat pump is ideal for indoor installation.
The big controller screen with blue LED backlight and simple operation gives the best experience to users.
High temperature geothermal ground source heat pump water heater for house heating 1) Heating capacity 3KW, 4.5KW, 6KW, 9KW. 2) Brine to water design, hot water outlet from 30DegC to 55DegC, suitable for floor heating and radiator, as well as domestic hot water. 3) Can work with master-controller or indoor thermostat. 4) Built-in heat curves (temperature compensation function), water temperature set value changes as per outdoor temperature. 5) Ultra quiet design, the whole heat pump system is on a floating plate isolated from the heat pump cabinet to reduce vibration and noise at the most extent. The inside is with noise absorption layers. 6) Big controller screen, with blue LED backlight, and simple operation menu and clean display. |
