Comparison Saturn ST-HT0498 2.5 kW vs Ergo HI-1625 2.5 kW

The area that the device can effectively heat. This parameter directly depends on the maximum power (see above). It should be noted that the actual efficiency of the heater in most cases does not depend on the area but on the volume of the room. Thus, the heating area can only be specified for a certain ceiling height. In most cases, manufacturers mean 2.5 m — this is the standard ceiling height in city apartments. If the ceilings are much higher, the heating area must be recalculated using special formulas. In general, it is worth orienting that 1 kW is enough for 10 m². However, manufacturers may slightly overestimate the heating area data.

The ability to adjust the power of the heater. Do not confuse this parameter with temperature control since several power modes primarily affect the heating rate, energy consumption and device wear.
