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 should be your first choice if your priorities are both to save on heating costs and to generate heat in an environmentally responsible way. After all, the energy a heat pump uses is free and available in unlimited supply from the environment. Only electrical power is required to drive the heat pumps.
This makes you independent of fossil fuels, and in addition, actively contributes towards reducing CO2 emissions and protecting the climate. With a heat pump, up to 80 percent of the total energy demand is taken 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, in the ground or in groundwater is used to efficiently heat domestic hot water and heating water.
The Vitocal 300-G Pro is a large heat pump for larger apartment buildings as well as commercial and municipal applications, with five output ratings to enable most requirements to be reliably met up to 1200 kW.
Vitocal 350-G Pro is a large heat pump that achieves high flow temperatures of up to 73°C, meeting the requirements of hygiene regulations for DHW heating. Also features advanced technology for efficient cooling.
With its high output, a KWT heat pump is designed for larger residential complexes and commercial operations. In addition, with slight adjustments, it can also be used to cool the living space in summer. The idea that a heat pump only suits new build projects has been long disproved. On the contrary, if an existing conventional oil or gas heating system is replaced with a heat pump as part of a modernisation project, there will be significant savings on heating bills and lower emissions at the same time (for example compared to a dual mode system).
Various natural sources are suited to heat recovery using a heat pump:
Not all these heat sources can be used everywhere. It is therefore necessary to consult the relevant authorities before making a decision, and discuss the technical options with KWT.
With the Vitocal 300-G/-W Pro heat pumps, Viessmann extends the company's range of standard heat pumps up to 290 kW. The Pro series features all the characteristics of the highly efficient Vitocal 300-G series. With seven output sizes, most requirements of residential and commercial buildings can be reliably met.
Standardising these appliances enables quick and comprehensive engineering, as well as providing transparent calculation parameters. Higher output levels can be achieved by linking up to five Vitocal 300 Pro heat pumps in a single cascade.
The electrical equipment is already integrated inside the heat pump casing as standard. Factory-fitted contactors for fail-safe primary and secondary pumps, as well as protection for the compressor, guarantee straightforward installation and the safe and rapid integration of the heat pump into the system.
The control philosophy was adopted from the Vitocal series for detached and semi-detached houses. Here too, the Refrigerant Cycle Diagnostic System (RCD) checks efficiency continuously and safeguards the efficient and reliable function at any operating point through the interaction between the electronic expansion valve (EEV) and the extensive sensor technology.
The Vitotronic 200 regulates up to three heating circuits, and thanks to its natural cooling function ensures pleasant ambient conditions on hot summer days. With the optional addition of a Vitocom 300 communication module, a comprehensive range of settings and system optimisations can be undertaken from anywhere via internet or mobile phone.
In all of our heat pumps, the compressors emit noise in the 50 to 60 Hz range. Thanks to the high quality construction of the frame and anti-vibration casing components, it has been possible to keep this noise within the casing. Vibrations on the base support are barely perceptible as the 3-D antivibration construction is specifically designed to dissipate oscillations. With sound power levels of, for instance, 65 dB (A) for the 197 kW heat pump, its values stand up well by comparison with other products in this market segment.
