WP Max Heat Pumps

Efficient use of environmental energy

Heat pumps are a developed technology. They make economic sense when the cost ratio of the current employed is favourable compared to other energy carriers. No other heat generator, as a ‘stand-alone’ device, receives a high energy rating as high as that of the heat pump. The heat pump draws at least 75% of its energy from free, available environmental energy in the earth, air or water. Only 25% is supplied in the form of electricity for operation of the heat pump. Nowadays, this can easily be provided using ‘green electricity’ from renewable energy sources. Thus, the consumer not only benefits the environment by saving energy, but saves hard cash as well. The user of a heat pump is also more independent of fossil-based, finite sources of energy and the price volatilities that they involve.

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

    Low emissions values

    Naturally, environmental friendliness in heat pump technology is a main consideration. But what makes a heat pump friendly to the environment to begin with? Heat pumps use the solar energy stored in air, water or soil to bring it to a temperature level necessary for heating purposes with the aid of a heat pump. But only a quarter of this additional energy is needed to generate 100 percent heating power – a peak level of efficiency. In addition, heat pumps themselves do not produce emissions during operation; unlike gas- or oil-based heating systems, they are not dependent on a combustion process. The more regenerative electricity is used, the greater the savings in CO2.

    Low heating costs

    As the heat pump requires only a small proportion of electricity in order to temper the heat obtained from air, water or earth to make it usable for heating purposes, it poses a much lower rate of loss than oil or gas heaters. While part of the energy is lost in the combustion process, a heat pump can generate the required heating energy by a factor of 4 or even higher! So one part electricity e.g. produces four parts of heat. Even with rising electricity costs, a heat pump is still very efficient and protects your wallet in the long run.

    No chimney and no chimney sweep

    Operators of a heat pump can save the costs of the chimney sweep. The regular sweeping and annual emissions controls are eliminated, since no combustion is required to operate a heat pump. Heat pumps work with the help of compression. This produces no emissions and renders the chimney itself superfluous. Although existing structures are usually fitted with a chimney, it is no longer required to run a heat pump. In the new construction area, this also saves the cost of building a chimney.

    Appreciation of real estate

    Owners of residential real estate seeking to rent or sell are increasingly confronted with the requirements of the ‘energy pass’. Energetic refurbishment and, last but not least, efficient heating systems are becoming increasingly important. A heat pump is a conceivable solution in this regard. Refurbishment based on considerations of energy consumption, with full thermal insulation, can quickly cost twice what it would cost to install a heat pump. Here, a crucial part of assessing the optimal mix for refurbishment is to take a holistic view of the building envelope and efficient plant technology. 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 the rental or sale of real estate with heat pumps, increasing their value in the process.
