Heating area
A very conditional parameter that slightly characterizes the purpose based on the size of the room. And depending on the height of the ceilings, layout and equipment, actual values may vary significantly. However, this item represents the maximum recommended area of the room that the device can effectively heat. This parameter directly depends on the maximum power (see above). It is worth noting that the actual efficiency of the heater in most cases depends not on the area, but on the volume of the room. In light of this, 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 considering that 1 kW is comfortable for 10 m², however, manufacturers may slightly overestimate the heating area data.
Heating modes
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.
Wheels
The presence of wheels in the design of the unit.
This feature is found exclusively in floor heaters. The convenience of the wheels is obvious: rolling the device is much easier than carrying it by weight. However, the stability of models without wheels and their aesthetic components is much higher than devices with wheels.
