Electric heating in comparison: advantages & disadvantages of modern heating systems

Electric heating systems are becoming increasingly popular thanks to technological advances. Whether as the main heating system or to support existing systems, they offer flexible and uncomplicated solutions for different requirements. In this article, we compare the advantages and disadvantages of electric heating systems and present the innovative heating solutions from 21energy that combine warmth with financial benefits.

How do electric heaters work?

Electric heaters convert electrical energy directly into heat. Depending on the type, this happens in different ways:

  • Infrared heating: Heats walls, objects and people in a targeted manner using radiant heat and creates a pleasant room climate.
  • Electric fan heaters: These devices generate warm air and are ideal for quickly heating small rooms.
  • Electric underfloor heating: Provides pleasant warmth from below and is often used in bathrooms or living areas.
