Which electric heater uses the least energy
- 21/ 07/ 2025
When choosing a room heater, a key concern is: which one consumes the least electricity? This is especially important in areas with limited power capacity or high energy prices.
What affects energy usage
Factors include the type of heater, room size, insulation level, set temperature, and presence of a thermostat.
Overview of common options
Convectors heat fast but consume more. Oil-filled radiators use 1.5–2.5 kWh. Infrared panels heat objects directly, but not always evenly or efficiently for full rooms.
Ceramic direct-heating panels stand out as one of the most efficient choices. With built-in heat storage and a dual heating principle, they average just 50 W per square meter.
UDEN‑S – low power consumption, high comfort
Ukrainian brand UDEN‑S offers a wide selection of energy-saving heaters. The UDEN‑700 model consumes just 0.7 kWh and efficiently heats rooms up to 15 m². You can find more in the UDEN‑S product catalog.
Conclusion
If you're looking for a heater that uses little power, ceramic direct-heating panels with heat accumulation are your best bet – energy-saving, safe, and stylish.
