Solar DC inverter superimposed double source heat pump 8KW COP 6.56

DC-inverter-split-Wärmepumpen zu ersetzen gas-Kessel-8KW,11KW,15KW
Solar DC inverter superimposed double source heat pump 11KW

Striking characters:
DC inverter Double heat source superimposed to get world best COP, legionella protection function, Auto start 2nd backup heating, Auto weather compensation heating curve. Trinity heat pump with heating,cooling and domestic hot water. With integrated solar work station.  Alternative to use ground water heat source.

Kolant DC inverter solar double source heat pump is an heat pump innovation with two layers heating source. It can use solar(or ground water source) together with air source. The two heat source are superimposed to reach 40% ~100% higher efficiency than normal heat pump. It even 40% higher efficient than normal inverter heat pumps.
The COP during standard frequency can reach 6.56 when solar temp is 15 degreeC.

Heating capacity is available for 8KW,11KW.

It can save much money for you. It can satisfy all countries refund requirement.  It can make space heating, cooling and domestic hot water.

Kolant solar double source multifunctional heat pump advantage:

1st advantage: It has 2 copper fin heat exchanger together with 1 plate heat exchanger to generate hot water so It can use solar or ground source water heat together with air source in the same time.  The COP is super imposed and can be  at least 40% higher efficiency even than normal DC inverter heat pump.

2nd advantage: It use DC inverter compressor, it is 20%~30% higher efficient in most operation.

3rd advantage: If solar water temp is high enough in sunny day, it can make passive heating room and DHW without compressor working. In this situation, it can save the most.

4th advantage: Solar layer evaporator will help to melt the heat pump evaporator frost and reduce the defrost cycle 80-100%, if solar temp is high, the heat pump never need defrost.  This will improve too much on the COP.

Do you notice other normal heat pump will not include the defrost loss on their standard nominated COP. But when air temp is lower than 5c, other normal heat pump will often need defrost function. The defrost will get heat from the room or DHW hot water. During the defrost, the heat pump will not heat the water, but cool the water. But our solar double layer source heat pump doesn’t need defrost if the solar water is high.

This heat pump is part of a heating system for domestic water, under floor and radiator room heating, designed for old house or new house.

The heat pump can control directly the solar heating system  A fan and a fin heat exchanger is installed for over heat protection of the solar circle,

The heat pump are including two units: indoor and outdoor units.
Indoor unit is solar working station and must be located inside rooms like cellar, car garage.

The heat pump outdoor main unit can work seperately with the solar work station if connect with ground water source.

Reliable Quality for saving maintenance cost: Our parts are always choosend with the top brand in the world Heat exchanger: SU316 stainless plate heat exchanger.

The compressor: Sanyo, Hitachi,Toshiba brand

Heat expansion valve: Emerson brand

Water pump: Wilo brand from Germany

Four way valve: Saginomiya brand of Japan
