For a long time, gas heating was considered the standard in German households. But times are changing — and with them technology. More and more people are choosing a heat pump, which is regarded as a more efficient and future-proof alternative. But why is it gaining in importance and what does that mean for gas heating? It's worth taking a look at the decisive factors.

Heat pump or gas heater: An overview

Die heat pump uses environmental energy from air, soil or groundwater and converts it into heating energy. It only requires electricity as drive energy, but generates many times as much heat. Thanks to its high efficiency, it not only reduces energy consumption, but also reduces heating costs. In addition, heat pumps are eligible for funding and meet the new legal requirements for climate-friendly heating. With a lifespan of up to 25 years, they are a future-proof solution for new buildings and renovated existing buildings.

Gas heating systems rely on the combustion of natural gas, which means direct dependence on fossil fuels. This results in high CO₂ emissions, and with increasing CO₂ taxes, heating with gas is becoming increasingly expensive. In addition, many government subsidies are being waived, while legal requirements make it increasingly difficult to install new gas heating systems. Gas prices are subject to fluctuations and the long-term availability of natural gas is uncertain. Maintenance costs are also higher than with a heat pump, as there are regular inspections and chimney sweeping costs. Anyone who relies on gas must reckon with rising costs and regulatory restrictions.

The following is a comprehensive comparison of both heating systems:

Cost comparison: heat pump vs. gas heating

Die Acquisition costs a heat pump Are between 15,000 and 30,000 euros, while a gas heater only 8,000 to 14,000 euros costs. However, there is government funding for heat pumps from up to 70%. This means that the actual costs for a heat pump are often lower after deducting the subsidy.

The annual heating costs A heat pump is included 500 to 1,500 euros, depending on the heat demand and the efficiency of the system. Gas heating, on the other hand, causes 1,500 to 2,500 euros Heating costs per year, which is primarily due to rising gas prices and CO₂ taxes. The heat pump is also cheaper when it comes to maintenance. The annual maintenance costs amount 100 to 300 euros, while a gas heater with 200 to 400 euros causes higher follow-up costs.

Comparing efficiency and energy consumption

Die Annual performance figure (JAZ) A heat pump is usually included 3.5 to 5.0. That means that from 1 kWh of electricity at least 3.5 kWh of thermal energy be won. Under optimal conditions, modern heat pumps can even JAZ of over 5.0 achieve. A gas heater, on the other hand, has a Efficiency of up to 99%so that they turn off 1 kWh natural gas maximum 0.99 kWh heat energy can generate. In practice, however, the actual efficiency is often lower, particularly in older heating systems with high exhaust gas losses.

In a well-insulated new building with 150 m² of living space, the power consumption of a heat pump is 3,000 to 4,500 kWh per year, during a gas heater 15,000 to 20,000 kWh natural gas needed. Consumption increases significantly in an unrenovated old building: A heat pump requires 6,500 to 9,500 kWh of electricity, but a gas heater 35,000 to 50,000 kWh natural gas per year.

Environmental balance: a comparison of CO₂ emissions

One heat pump Depending on the power source, causes up to 100 g CO₂ per kWh. Will she be with green electricity or one of your own photovoltaic system operated, the company remains almost climate-neutral. When purchasing from Power from the German grid Are produced on average 300 to 1,000 kg CO₂ per year.

One gas heater Causes approximately 250 g CO₂ per kWh. This results in annual emissions of 3,750 to 12,500 kg CO₂. In addition, the CO₂ tax and will continue to rise in the coming years, so that Gas prices are constantly rising. This not only makes fossil heating systems more environmentally harmful, but also more expensive in the long term.

Future security: legal requirements and heating replacement

Since In 2024, there are stricter requirements for new heating systems, which accelerate the transition to renewable energy. Pure gas heating systems may no longer be installed in new buildings. heaters must at least 65% renewable energy use. Existing gas heating systems may continue to operate, but costs are increasing due to CO₂ tax continuously. In addition, owners must from Completely abandon fossil fuels in 2045, so that it is necessary to replace the gas heater in the long term.

In future, gas heating systems could be equipped with 100% hydrogen or biogas but these solutions are insecure. green hydrogen is barely available and expensive so far. Biogas is only available to a limited extent, so that widespread use does not seem realistic. Without a guaranteed supply of climate-neutral gas, fossil heating systems remain unprofitable in the long term.

One Hybrid solution from gas heater and heat pump may be a temporary solution. In these systems, the heat pump covers the majority of the heat requirement, while the gas heater only steps in at very low temperatures. This reduces gas consumption and CO₂ emissions, but in the long term, dependence on fossil fuels remains. In addition, fall high investment and operating costs for two heating systems on. Who already has a Gas heating has, may consider a hybrid solution. For new buildings, a pure heat pump the more sustainable choice.

Is a gas heater or a heat pump better?

In the long term, a heat pump is more worthwhile than gas heating. It is more efficient, more climate-friendly and financially attractive thanks to high subsidies. Although acquisition costs are higher, operating costs are lower. In addition, there is no dependence on fossil fuels.
