Gree Versati III DUO 14.0/12.6kW, S1GRE- Air-to-water heat pump indoor unit

The Gree Versati III DUO 14.0/12.6kW indoor unit is a reliable and efficient third-generation air-to-water heat pump indoor unit. The device is designed for heating, cooling, and domestic hot water preparation systems. The Versati III series stands out for its durability, favorable price, and consistently high efficiency even at low outdoor temperatures. The package includes a three-way valve, a room thermostat (temperature sensor), a water heater controller, a signal cable between the indoor and outdoor units, a coarse mesh filter, and an outdoor unit bottom plate heating cable.

This heat pump indoor unit is used as the main energy collection component, transferring heat from the environment into the internal heat pump system. The indoor unit is capable of efficiently utilizing electricity for heating and cooling processes. This indoor unit features an integrated 190-liter domestic hot water tank. The water supplied to the system can be heated up to +60°C, and domestic hot water from +40°C to +80°C.

The device also features a durable construction and corrosion protection, making it suitable for operation in various climatic conditions. The heat pump's operating parameters at T=+7 °C/+35 °C – nominal heating capacity (underfloor heating): 14.0 kW. The device also has an exceptionally high coefficient of performance (COP) of up to 4.35. The cooling capacity (underfloor cooling) at T=+35°C/+18°C is 12.6 kW, with an energy efficiency ratio (EER) of up to 3.7. The unit also features an integrated touch-sensitive control screen and built-in WiFi. The refrigerant used in the device is R32. An auxiliary backup heating element is also integrated into the indoor unit, which is useful when the heat extracted from the air is insufficient to raise the temperature of the heating medium.

The integrated plate heat exchanger guarantees excellent heat transfer efficiency and resistance to thermal fluctuations. This is crucial for maintaining stable operation over many years. This series unit is compatible with hydraulic modules and boilers, allowing this block to be used in various system configurations.

To be paired with the outdoor unit, code S1GRE-GRS-CQ14PD/NHH2-M(O). Comes with up to a 3-year warranty.
