The technology of heating by infrared radiation has been greatly improved in recent years. It is the only one that allows the production of real efficient electric «mirror» heaters (not inertia radiators or other convectors). Also, mirror heaters with a power of 450W, 500W, 600W, 700W are sufficient for most projects to heat up to 15 m². For larger rooms, such as living and dining rooms, 1000 watts are sufficient with the highest quality heaters. Keep in mind that power is equivalent to electricity consumption, and is not always a guarantee of efficiency! As a result, investing in a 2000W electric mirror heater no longer makes sense today.
