Why Switch to an Alternative to Gas Heating?

Gas heating systems are widely used due to their reliability and low initial costs. However, recent developments make switching increasingly attractive:

Rising energy costs: Gas prices have steadily increased in recent years, further burdened by CO₂ taxes
Climate protection: Gas heating emits significant amounts of CO₂ and no longer fits into a sustainable energy future.
Political regulations: Stricter regulations or even bans on installing new gas heating systems may be introduced in the future. For more information, visit the German Environment Agency (UBA).

The Best Alternatives to Gas Heating at a Glance

The following table provides an overview of the pros and cons of the most popular alternatives:

Heating system	Advantages	Disadvantages
Heat pump	Almost emission-free (when using green electricity) Subsidies of up to 45% (e.g., through BAFA or environmental grants) Can be combined with photovoltaic systems	High initial costs Efficiency depends on good insulation
Pellet heating	Sustainable and climate-neutral Suitable for poorly insulated building	Requires storage space Higher particulate emissions
Solar Thermal + Electric Heating	Independent of fossil fuels Low operating costs in sunny conditions	Weather-dependent Needs additional heating in winter
District heating	Convenient and low maintenance No fuel storage needed	Limited regional availability Often non-transparent pricing model
Electric Heating Solutions (21energy)	Easy installation with no major renovations High energy efficiency Additional financial benefit through Bitcoin mining	Dependent on electricity supply Higher operating costs when using grid power only

When Is Switching Worth It?

For new buildings: Heat pumps or pellet heating systems are ideal for energy-efficient homes.
For existing buildings: Pellet systems, hybrid solutions, or electric heating offer flexible options.
With photovoltaics: Combining electric heating with solar panels maximizes efficiency and reduces operating costs.
For innovative homeowners: With 21energy’s heating systems, you also benefit financially.

Conclusion: The Best Alternative to Gas Heating

Rising energy prices and ambitious climate goals make switching to modern heating systems essential. Whether it's heat pumps, pellet heating, or electric solutions – there's a suitable option for every home.
