New project by air conditioning industry leader - Heat from Gree

Heat from Gree is an ecosystem of advanced heating appliances focused on providing heat and comfort. Effectively and for years to come.

For nearly three decades, Gree has been a leader in cooling solutions for homes, apartments and commercial premises. Developments in technology have brought Gree cooling equipment to the highest levels of efficiency and intelligent operation, while creating a natural space for product and service development in more areas. Gree also continues its mission in the area of building heating, focusing on providing valuable products and services to customers who are looking for excellent solutions to efficiently and energy-efficiently heat apartments, homes, or businesses. So let's explore the three pillars of the "Heat with Gree" offer.

Air conditioners for heating - the new face of air conditioning

Upgraded air conditioners for heating are perfect not only for reheating rooms, but can also be the only source of heat in them. The efforts of engineers and designers have resulted in models that heat at outdoor temperatures as low as -30°C, or feature an energy class of A+++.

Why heat with an air conditioner? An air conditioner, thanks to the supply of warm air, can raise the temperature in a room by several degrees even in 20 minutes. Moreover, these devices allow you to precisely maintain the desired temperature in the room, and their operation is extremely simple. All you need to do is start the air conditioner, select the heating mode, set the desired temperature and adjust the intensity of the air supply. They do not require storage and refueling, or constant user maintenance. They are also a clean source of heat. This is because they do not produce any by-products of the heating process such as ash or exhaust fumes. In addition, the air conditioner, as an air-to-air heat pump, is covered by subsidies, which can be obtained both for the replacement of the heat source with an air conditioner and for the purchase of an air conditioner as a heat source for a newly built house.

Versati heat pumps - clean energy and savings

Gree is also heat pumps, a heating technology that uses refrigeration systems that work with water systems. Versati units are the ideal solution for efficient, economical and easy-to-use heating for single-family homes.

Versati units come in Monoblock, Split and - as of January 2023 - also in All in One versions. They can be used for both heating, cooling and domestic hot water preparation, and their purchase is subject to subsidies under environmental programs provided for residential homes.

Gree Versati All in One heat pumps are Split-type units with a built-in 185-liter hot water storage tank. The integration of the tank with the internal hydromodule ensures convenience in both the selection and installation, as well as the operation of the unit. It also saves space compared to a system with an external tank. The dimension of the indoor unit is only 60 x 65 cm with a height of 180 cm. One compact unit provides domestic hot water and heating water. What's more, the installation of the unit does not require additional installation and components to connect the tank. The pump, which comes in heating capacities from 4.0 to 15.5 kW, is equipped with a modern touchscreen controller with a menu in Polish and a Wi-Fi module that allows the unit to be controlled from anywhere via an app.

Versati Monoblok pumps are available in a new and improved version. The units, which have gained great popularity due to their ease of installation and high efficiency, now feature even higher energy efficiency coefficients and increased heating reliability. The COP of these models can even reach more than 5.0. In addition, the new series of monoblock heat pumps is equipped with factory-fitted peak heaters. Thanks to two-stage regulation, they can support the heat pump during extremely low outdoor temperatures. Models with heating capacities from 8.2 to 15.7 kW are available.

Versati Split pumps are devices that make it possible to realize low-temperature heating, domestic hot water preparation and air conditioning through fan coils. With a wide power range from 6.0 to 15.5 kW, they are used both in small residential buildings and small commercial investments. High parameters and modern design make them characterized by exceptional energy efficiency and reliability. Versati Split is equipped with a built-in 3-way valve, which makes it easy to install a hot water tank.

VRF systems - GMV6 with heat recovery

The third installment of the Warmth with Gree project are advanced, large VRF systems that can serve office buildings and multi-tenant buildings. They increase the attractiveness of investments through the use of environmentally friendly Heat Recovery systems, enabling heat recovery. These solutions provide the possibility of simultaneous implementation of heating and cooling operation and significantly increase the energy efficiency of buildings. Energy-efficient heat recovery control technology and a high-efficiency DC inverter compressor make it possible to achieve an efficiency ratio of simultaneous heating and cooling ofup to 9.0. The sixth-generation heat recovery systems have therefore increased this ratio over the GMV5 HR by 12.5%. In addition, the latest version of GMV6 HR systems allows integration with a hydrobox and cooperation with water systems. Thus, the systems can handle water heating and DHW preparation. What's more, hot water preparation can be implemented with heat recovery during cooling.
