Most energy-efficient heaters

Electric heating is convenient, especially when there’s no access to gas or centralized systems. But with electricity prices rising, more people are looking for ways to heat their homes without overpaying. In this article, we’ll look at the most energy-efficient heaters and explain why they truly help you save.

What does “energy-efficient heater” mean?

It’s not just a device with low power. A truly energy-efficient heater delivers sufficient warmth while using the least amount of electricity. It’s also important how long the heat remains in the room after switching off and whether temperature control is available.

Most efficient types of heaters

Ceramic panels with heat storage
They operate on the direct heat principle, warming walls and objects instead of the air. This keeps rooms warmer for longer.
Consumption: 50 W per m²

Infrared heaters
They heat objects directly and work well in poorly insulated rooms, but require precise direction.
Consumption: 0.8–1.2 kWh

Heaters with a thermostat
They turn on only when needed and help reduce unnecessary energy use.
