The Bosch 9.2 kW split-type heat pump from the German manufacturer ensures high efficiency throughout the year. The modulated heating capacity of the device guarantees the production of an amount of heat matching the building's demand. The heating and cooling function ensures thermal comfort in both summer and winter. The device provides heat supply even at very low outdoor temperatures. Intuitive operation is a definitive advantage of Bosch heat pumps, thanks to the HPC400 controller with the option to use a room controller for each heating circuit. The product is equipped with a circulation pump, expansion vessel, safety valve, 3-way valve, electric heater, stainless steel domestic hot water cylinder with an additional coil, and an internet connection enabling remote operation. The installation of the device is quick and easy. The outdoor unit is lightweight, allowing it to be mounted on the ground or the building's wall. A high energy efficiency class circulation pump is integrated into the indoor module. The lack of a need to install a buffer tank due to inverter technology reduces investment costs. The Compress 3000 AWS E air source heat pumps are primarily designed for newly built single- or multi-family buildings and can operate independently. In addition to the MS version, there are 3 other compact heating modules to choose from, which are installed indoors. They provide a flexible heating system solution in a new or existing building (cooperating with another heat source). Two of them are fully equipped, which, combined with the heat pump, creates a complete heat pump installation and ensures no additional costs.
