Commercial Heat Pumps

Heating with renewable energy from the environment – even in the higher output ranges

Natural heat is an advanced and cost effective alternative to fossil fuels. It is available free of charge and offers independence from oil and gas.

Heat pumps offer ideal conditions for reducing heating bills and achieving environmentally responsible heat generation. After all, the energy a heat pump uses is free and available in unlimited supply from the environment.

With a heat pump, up to 80 percent of the total energy demand can be drawn from nature in a highly effective and environmentally responsible manner. Only 20 to 30 percent electrical energy needs to be invested.

The principle is as simple as it is ingenious: the solar energy stored in the ambient air, ground and groundwater is used to efficiently heat domestic hot water and heating water.

Heat pumps are also available with high outputs and are designed to meet the energy demand of larger residential complexes and commercial operations. The operating mode can be „reversed“, allowing the heat pump to be used for cooling in summer too. The idea that a heat pump only suits new build projects is outdated. On the contrary, if an existing conventional oil or gas heating system is modernised or supplemented with a heat pump (to form a dual mode system), significant reductions in heating costs can be achieved and emissions lowered at the same time. Independence from fossil fuels actively contributes to reducing CO2 emissions and protecting the climate.

Recovering environmental energy

Various natural sources are suited to heat recovery using a heat pump:

• Water – such as groundwater, river or lake water, waste water
• Ground – via geothermal probes, geothermal collectors, energy piles
• Air
• Waste heat

Not all of these heat sources can be used in all locations. It is therefore necessary to

consult the relevant authorities before making a decision, and discuss the technical options with Viessmann.

The Pro series of the Vitocal 300-G Pro heat pumps features all the characteristics of the highly efficient Vitocal 300-G series.

The five output ratings enable most requirements from residential and commercial buildings to be reliably met.

These appliances are standardised, enabling quick and comprehensive engineering, as well as transparent cost calculation.

As a heat pump from standard production, the Vitocal 350-HT Pro series delivers flow temperatures up to 90 °C and utilises heat source temperatures up to 50 °C. This makes it particularly suitable for the utilisation of waste heat and for the generation of high temperatures for industrial and commercial processes, or for older local heating networks.

In addition, the control unit features many communication options. LAN-supported systems as well as Modbus and BACnet interfaces can be used. These make the system accessible for remote monitoring and integration into building management systems. The 5.7 inch colour touchscreen offers intuitive operation and easy control.

The use of the new HFO refrigerant, R1234ze, means that this series of appliances already meets the refrigerant regulations set for 2020 and beyond. The GWP (global warming potential) is in the single-figure range and is therefore almost as low as that of natural refrigerants.
