Ochsner Wärmepumpen GmbH products

The integral DHW tank of the compact hot water heat pump has a capacity of 250 litres and delivers a usable volume of water of up to 288 litres for households of up to 4 people. A coil can be used to also connect a solar thermal system or boiler. The fully wired appliance is quick to install and has a footprint of less than half a square metre.

The split appliance generates DHW up to 60°C for external tanks with up to 500 litres capacity and is suitable for households of up to 5 people. The fully wired and compact appliance is quick to install. It can be easily combined with existing pellet boilers, solar thermal or conventional boiler systems. The model can be combined with a 300 or 500 litre tank.

The heat pump is suitable for building heat loads between 7 and 12 kW. It delivers heat and DHW up to 65°C. It can also be configured for active cooling. The slimline indoor unit has a footprint of less than half a square metre. The outdoor unit is equipped with a highly efficient horizontal bench evaporator.

The heat pump is suitable for building heat loads between 6 and 10 kW. It works with a speed controlled compressor and delivers heat and DHW up to 60°C. It can also be configured for active cooling. The indoor unit has a footprint of less than half a square metre. The outdoor unit is equipped with a vertical fan.

The OCHSNER AIR HAWK 208 heat pump is the tailored solution for detached houses with superior energy efficiency. Thanks to the proven OCHSNER horizontal split evaporator system, the AIR HAWK 208 is exceptionally quiet in operation – in standard mode, the sound pressure level at a distance of 3 m from the outdoor unit is only 28 dB(A).

The ground acts as a free and abundant heat store, making it an ideal heat source. With the OCHSNER TERRA system, geothermal energy is collected by means of a brine circuit and transferred to the heat pump. During installation, you can choose either horizontal collectors, trench collectors or geothermal probes.

The heat pump is suitable for building heat loads between 6 and 8 kW. It delivers heat and DHW up to 65°C. It can also be optionally configured for passive cooling. The slimline indoor unit has a footprint of less than half a square metre.

The heat pump is suitable for building heat loads between 7 and 10 kW. It delivers heat and DHW up to 65°C. It can be optionally configured for passive cooling. It uses patented OCHSNER stainless steel shell and tube heat exchangers, which offer maximum reliability even when water quality is lower. The slimline indoor unit has a footprint of less than half a square metre. The Aqua 11 can be cascaded for higher output demands.

Heat pump buffer tanks, also known as thermal stores, absorb heat, store it with low losses, and keep it ready for use in the heating system. They ensure a constant supply of heat and increase the service life of the heat pump compressor by significantly reducing its activation cycles. This allows bivalent or multivalent charging from different heat sources.

The OCHSNER Unifresh fresh DHW heater combines a buffer tank with a freshwater coil. It can be used purely as a DHW heater or as a DHW station and buffer tank for the heating system. It can be supplied with water either from the heat pump alone or on a bivalent basis, for example from the heat pump and the boiler.
