R290 heat pump water heater


Features:

Wotech heat pumps are equipped with energy-efficient inverter compressors that allow variable heating capacity adjustment. This increases the efficiency of the entire system and reduces the operating costs of the pump.  The higher the coefficient, the more heat can be generated using the same amount of electricity.


R290 Green Gas at low GWP(3)

As the world market has been chasing after environment friendly heat pump products,Wotech launched to the market R290 environment friendly heat pumps.

Why choose R290?

R290 is a natural refrigerant with a very low GWP* of three. 

This offers the following advantages:

• Future-proof, as not affected by the F-Gas Regulation

• Higher flow temperature of up to 70℃

• Good SCOP,energy label rating W35℃ A+++/ W55℃ A++

• Higher hot water comfort and protection against legionella without electric auxiliary heating

• Wider performance envelope with operating temperature ranging between -25°C and +43°C

• Reduced refrigerant charge compared to R410a and R32 

Refrigerant Revolution

ENERGY EFFICIENCY RATING LABEL

Space heating Series is specially developed with the most cutting-edge heat pump technology and modern design to meet stringent requirements for efficiency, stability and quietness. Not only does Space heating Series use R290 green gas, but also is rated with A+++ energy label. With top energy rating A+++, the unit is energy efficient and can greatly reduce energy bills for users.

R290 energy label A+++

Monoblock

Wotech provides the monoblock heat pump with main circulation pump built inside. When installing the unit, installer should connect the heat pump with other parts including the buffer tank (for space heating/cooling), storage water tank (for domestic hot water) and water pumps (for space heating/cooling water circulation and domestic hot water). External fittings are also needed in cluding the safety valve, water refill valve and hot water valves (three-way valve).Temperature sensor should be added in the storage water tank. Additional electric heater can be installed in the DHW tank or the buffer tank which can getthe control signal from the heat pump.

Application with multiple heat source



Two heating circuits [as standard]

• More flexibility thanks to two control zones

• Independent control of underfloor heating and radiator heating temperature

• No need to purchase an extension module for second heating system

Contributing to a descarbonised society

The heat pump is considered a "green' choice as the heat energy is taken from the environment, making it a sustainable option.

*It maintains a comfortable indoor temperature while significantly reducing environmental burden.

*Wote R290 air to water Heat Pumps can also be connected to an e-heater, gas boiler, solar thermal or Py system in order to increase efficiency and minimise environmental impact.

Eco mode

Once ECO mode is slected, Wotech air to water heat pump sets the outlet water temperature automatically according to the outdoor ambient air temperature.Climate curve


DHW tank disinfection

Maintain pristine quality of the water tank's DHW and eliminate germs and bacteria by increasing the temperature of the water in it up to 65C.
