Düsseldorf – October 28, 2026 -- Infrared heaters deliver warmth at the push of a button and are easy to install, but running them for long periods can drive up electricity costs, according to energy provider Grünwelt Energie.

Infrared heaters work best as a supplementary heat source

Infrared heaters warm rooms with direct thermal radiation. Grünwelt Energie says they are strongest as an add-on heater, for example in a bathroom or guest room. The devices are relatively cheap to buy, usually need no regular maintenance and stir up little dust.
