Revolution in heating technology: How efficient are electric heating systems really?
In a world where energy efficiency and sustainability are becoming increasingly important, the question arises: are electric heaters a smart choice? This comprehensive blog post sheds light on the efficiency of electric heating and shows you how you can use modern technologies such as the Bitcoin heaters from 21energy to heat not only efficiently, but also in a future-oriented way.
What does heating efficiency mean?
The efficiency of a heating system describes how much of the energy used is actually converted into usable heat. Electric heating systems have a clear advantage here:
-
Almost 100% efficiency: electric heaters convert electricity directly into heat, without losses through exhaust gases or pipes.
-
Flexible use: They can be used in a targeted and demand-oriented manner, which avoids unnecessary energy consumption.
| Advantages | Disadvantages |
|---|---|
| Direct energy conversion | No energy loss through pipes or exhaust fumes. |
| Fast response time | HHeating at the touch of a button - ideal for temporary use. |
| Can be combined with green electricity | Particularly sustainable when using renewable energies. |
| Easy to regulate | Individual control possible for each room, which further optimizes energy consumption. |
Challenges in the efficiency of electric heaters
Despite their many advantages, there are also aspects that should be taken into account:
-
Electricity prices: In Germany, Austria and Switzerland, electricity costs are relatively high by international standards.
-
Areas of application: Electric heating systems are less suitable as main heating for large, poorly insulated buildings.
-
CO₂ balance: The environmental friendliness depends heavily on how the electricity is generated.

Bitcoin heating from 21energy: efficiency redefined
The Bitcoin heater from 21energy takes the concept of efficiency to a new level. It combines heat generation with cryptocurrency mining, allowing you to not only heat your home but also benefit financially at the same time.
Advantages of Bitcoin heating:
-
Maximum energy utilization: every kilowatt hour used is used twice - for heat and Bitcoin mining.
-
Sustainability: Particularly efficient in combination with green electricity or photovoltaics.
-
Cost reduction: Mining revenues can significantly reduce electricity costs.
"The Bitcoin heater from 21energy is more than just a heater - it's a step into the future."

| Heating type | Efficiency | Flexibility | Environmental friendliness |
| Electric heating | 99 % | Very high | High (with green electricity) |
| Gas heating | 80 – 95 % | Medium | Low |
| Heat pump | 300 % (COP-Value) | High | Very high |
| Bitcoin heating | 100 % + Mining | High | High (with green electricity) |
Tips for the efficient use of electric heating
-
Combine with green electricity: Use green electricity or install your own photovoltaic system.
-
Room-by-room control: Avoid heating unused rooms with smart thermostats.
-
Optimum insulation: Good windows and insulated walls significantly reduce energy consumption.
-
Use innovative systems such as Bitcoin heaters: These not only provide heat, but also financial added value.
Electric heating systems are extremely efficient and an excellent choice in many cases. They score particularly well thanks to their flexibility, ease of installation and combination with renewable energies. However, if you want maximum efficiency and sustainability, you should consider the Bitcoin heaters from 21energy. They combine state-of-the-art technology with the possibility of reducing energy costs through mining revenues.
„Heating has never been so efficient - take the step into the future with electric and bitcoin heaters.“
