Modern heating systems: Why heat pumps are the better choice
Heat pumps offer numerous advantages compared to other heating systems, making them an attractive option for modern and sustainable heating solutions. These benefits not only concern energy efficiency and environmental friendliness, but also long-term costs and security of supply. The most important advantages of heat pumps over conventional heating systems such as oil, gas and pellet heating systems are explained in detail below.
1. High energy efficiency
One of the biggest advantages of heat pumps is their impressive energy efficiency. While conventional heating systems such as oil or gas heaters typically have an efficiency of 80 to 90 percent, heat pumps can achieve an efficiency of 300 to 500 percent. This means that they can generate three to five kilowatt hours of heat from one kilowatt hour of electricity by using the heat stored in the ambient air, soil or groundwater.
In contrast to fossil fuels, which generate energy through combustion and cause losses in the form of waste heat, heat pumps use existing environmental energy. This makes them particularly efficient and allows them to produce large amounts of heat using relatively little electricity. This high efficiency also results in lower operating costs compared to gas or oil heating.
2. Lower operating costs
Another advantage of heat pumps is their comparatively low operating costs. Since they obtain the majority of the energy they require from the environment, they only require a small amount of electrical energy to operate the compressor. This means that if a heat pump is correctly dimensioned, the heating costs can be around a quarter lower than those of a gas heater and even a third lower than those of an oil heater.
In the long term, the higher purchase costs of heat pumps are amortized through the savings in operating costs. Particularly in times of rising prices for fossil fuels such as gas and oil, the heat pump offers a cost-effective and stable alternative.
3. Use of renewable and inexhaustible energy sources
Heat pumps use renewable energy sources such as air, soil or groundwater, which are practically inexhaustible. Unlike fossil fuels, these natural resources are not subject to economic or political fluctuations. This makes heat pumps particularly future-proof and independent of volatile prices on the energy market.
In addition, these energy sources are emission-free, which means that heat pumps do not release any harmful greenhouse gases during operation - provided they are powered by green electricity. This means they contribute significantly to reducing CO₂ emissions and are an environmentally friendly alternative to conventional heating systems.
4. Future security and independence from fossil fuels
Dependence on fossil fuels such as oil and gas poses not only an economic risk, but also an ecological problem. Fossil fuels are finite and their prices fluctuate greatly due to geopolitical developments. The Russian war of aggression against Ukraine, for example, has shown how much gas and oil prices can rise.
Heat pumps, on the other hand, make households more independent of these developments because they do not require any fuel. They are based on electricity as the primary energy source, which increasingly comes from renewable sources. This ensures stable and predictable operating costs and offers long-term security of supply.
5. Low maintenance and durability
An often overlooked advantage of heat pumps is their low maintenance requirements compared to other heating systems. Since heat pumps do not use combustion processes, there are fewer wearing parts and therefore less need for repairs. In contrast to pellet or oil heating systems, there are no combustion chambers to clean or ash to dispose of.
Heat pumps have a service life of more than 20 years and are largely maintenance-free during this time. All that is required is regular inspection of the system to ensure it is functioning optimally. This longevity makes heat pumps a reliable and cost-effective solution for long-term use.
6. Space saving installation
Compared to pellet heating systems or other systems that need to store fuel, heat pumps require significantly less space. There is no need for storage rooms for pellets or tanks for oil or gas. An air-water heat pump can be installed to save space, especially in new buildings or well-insulated old buildings.
Even if ground or water heat pumps require a little more construction effort (e.g. drilling for geothermal probes), the overall space requirement remains more manageable than with systems with fuel storage.
7. Versatile uses
Heat pumps have a wide range of uses: They can be used not only to heat buildings, but also to prepare hot water and cool in summer (if equipped accordingly). Geothermal heat pumps are particularly suitable for this dual function as they can both heat and cool.
In combination with other technologies such as photovoltaic systems, heat pumps can also be operated even more efficiently. By using self-generated electricity from solar energy, operating costs can be further reduced and CO₂ emissions minimized.
8. Government funding
Another important advantage of heat pumps is the government funding for their installation. In many countries there are generous subsidies for the installation of heat pump systems to encourage the switch to renewable energy. In Germany, for example, up to 70 percent of the investment costs can be covered by government funding programs.
These subsidies make switching to a heat pump more financially attractive and help the investment pay off more quickly.
The advantages clearly outweigh the disadvantages
Heat pumps offer numerous advantages over conventional heating systems:
- They are extremely energy efficient and offer lower operating costs.
- They use renewable energy sources from the environment and are therefore environmentally friendly.
- They make households independent of fossil fuels and their price fluctuations.
- They have low maintenance and a long service life.
- They require less space than fuel storage systems.
- They can be used in a variety of ways (heating, cooling) and can be easily combined with photovoltaic systems.
- Government funding programs provide financial support for the transition.
All of these factors make heat pumps a future-proof solution for sustainable heating - both in new buildings and in well-insulated existing buildings.
