Heat pumps for the use of environmental energy

Heat Pumps WP Max and WP Grid

Efficient use of environmental energy as stand-alone system (Max) or district heating system (Grid)

Heat pumps are a well-engineered technology. They pay off when the cost ratio of the electricity used to other energy sources is favourable. No other heat generator receives such a high energy rating as the heat pump as a "stand alone" device. The heat pump uses at least 75% of environmental energy from the earth, air or water available free of charge. Only 25% is supplied in the form of electricity to operate the heat pump. Nowadays, this can easily be done with "green electricity" from renewable energy sources. This means that the consumer not only saves environmentally conscious energy, but also cash money. The user of a heat pump is also more independent of fossil, finite energy sources and the associated volatile price development. ratiotherm manufactures the heat pumps for use as air-to-water, brine-to-water or water-to-water heat pumps itself. A quality product: "Made in Germany".

    Flex by ratiotherm

    The heat pump as heating and cooling system must be designed correctly for smooth and long operation. The heat pump's performance is subject to a wide variety of requirements due to its operation in summer and winter. For higher power requirements, several heat pumps are often connected in cascades in order to meet the different requirements (heating, cooling, hot water preparation). In the small and medium output range, inverter technology is increasingly gaining acceptance. ratiotherm set a development focus here years ago and is equipping more and more models with this technology.

    By using an inverter, the output of the heat pump adapts to the actual and current heating or cooling demand. This guarantees uniform, energy-efficient and gentle operation of the heat pump.

    The inverter-controlled DC compressors are among the most efficient compressors on the market and are currently state of the art. They have advantages due to their wide range of applications and also convince in the partial load range with very high coefficients of performance. State-of-the-art control technology ensures exact monitoring of the heat pump's operating limits. The control always aims at balancing the requirements as quickly as possible with 100% of the available capacities. A limitation of the maximum output is also possible in order to meet the heating requirements of the building at any time. At ratiotherm, the abbreviation Flex is found in the product names of the individual heat pump series when efficient inverter technology is used.

The basic properties of this technology allow not only efficient heat generation but also very effective cooling. Heat pumps from ratiotherm are the preferred choice where, in addition to standard applications, special applications and an integrated system solution are required.

The following important aspects also speak in favour of this type of heat generation:

    Low emission values

    Of course, the environmental friendliness of the heat pump technology is in the foreground. But why is a heat pump friendly to the environment at all? Heat pumps use the solar energy stored in air, water or soil to bring it to a temperature level required for heating purposes with the help of a heat pump. Of this additional energy, however, only a quarter is needed to generate 100 percent heating power - maximum efficiency. In addition, heat pumps themselves do not cause any emissions during operation, since they are not dependent on a combustion process, such as gas or oil heating. The more electricity is generated from renewable sources, the greater the CO2 savings.

    Low heating costs

    Since the heat pump requires only a small amount of electricity to temper the heat extracted from air, water or soil to such an extent that it can be used for heating purposes, it has a significantly lower loss rate than oil or gas heaters. While part of the energy is lost during the combustion process, a heat pump can generate the required heating energy by a factor of up to 4 or even more! One part of electricity, for example, becomes four parts of heat. Even with rising electricity costs, a heat pump still works highly efficiently and is easy on the wallet in the long term.


    No chimney and no chimney sweeper

    Operators of a heat pump can save the costs for the chimney sweep. Regular sweeping and annual exhaust gas checks are no longer necessary as the operation of a heat pump is not based on the combustion principle. Heat pumps work with the aid of compression and no emissions are produced, which at the same time makes the chimney superfluous. Although existing buildings are usually equipped with a chimney, this is no longer required for the operation of a heat pump. In new buildings, this also saves the construction costs for the chimney.

    Value increase of the real estate

    Owners of residential real estate are increasingly confronted with the energy pass in the face of rentals and sales. Energy-efficient renovation and, last but not least, an efficient heating system are becoming increasingly important. For this point a heat pump is the conceivable solution. A renovation according to energy aspects with full thermal insulation quickly costs twice as much as the installation of a heat pump. The holistic view of the building envelope and efficient system technology is decisive at this point in order to assess the optimal mix of a renovation. The reduction of primary energy is also recorded in the energy pass. In times of high energy prices, this can be a valuable argument for renting or selling real estate with heat pumps and thus increase its value.
