Rising energy costs make it increasingly important to look for affordable and efficient heating solutions. Electric heating is often considered expensive, but with the right strategies you can actually heat cheaply with electricity. Particularly exciting are modern technologies such as Bitcoin heating systems, which generate heat and offer an additional source of income at the same time.

How can you heat cheaply with electricity?

Here are some clever ways to reduce your heating costs:

  1. Use night-time electricity tariffs: Many providers offer cheaper tariffs at night - perfect if you adjust your heating times accordingly.
  2. Combine a photovoltaic system: You can drastically reduce your heating costs with self-generated solar power.
  3. Use modern, efficient heating appliances:
Infrared heaters
➞ Fast heat and low purchase costs.
Heat pumps
➞ Very energy-efficient and environmentally friendly.
Bitcoin-Heaters
➞ This innovative solution from 21energy uses the waste heat from Bitcoin miners to heat your home and earn Bitcoin at the same time.
Bitcoin heaters make it possible to reduce heating costs and earn a passive income at the same time.

When is heating with electricity worthwhile?

The purchase costs for an electric heating system are generally lower than for other heating systems. However, the operating costs are often higher. Heating with electricity is therefore particularly worthwhile in the following situations:

  • If you have a well-insulated property and require little heating energy.
  • If you can generate some or all of your electricity yourself, e.g. with a photovoltaic system.
  • If you are looking for short-term solutions, for example for vacation homes or rarely used rooms.

Tips for better efficiency when heating with electricity

  • Install smart devices: Heaters with smart thermostats adapt the heating output to your daily routine.
  • Better insulation: Well-insulated walls and windows prevent unnecessary heat loss.
  • Optimize energy storage: Use systems with storage options such as underfloor heating.

Advantages and disadvantages of heating with electricity

Heating with electricity has some clear advantages - but also a few disadvantages that you should be aware of:

Advantages:

  • Simple installation and hardly any maintenance
  • Environmentally friendly if green electricity or your own solar energy is used
  • No dependence on fossil fuels
  • Flexible for use in new and old buildings

Disadvantages:

  • Higher operating costs with unfavorable tariffs
  • Dependence on electricity price fluctuations
  • Efficiency depends heavily on the selected heating system

How are electricity prices developing?

Electricity prices have risen steadily in recent years and are influenced by many factors, including political decisions, the energy transition and the availability of renewable energies. While fossil fuels are becoming more expensive and scarcer, there are also more and more opportunities to generate electricity yourself.

Experts assume that the price of electricity will continue to fluctuate in the coming years, but innovations such as electricity storage and decentralized energy production offer opportunities to reduce costs.

„Anyone who looks at alternative solutions such as solar power or efficient heating systems at an early stage can save costs in the long term..“
