Heating zones
The number of heating zones provided in the device. A heating zone is an area of the heater that can be turned on and off separately from other areas (and on some models even power can be adjusted for each zone separately). The number of such zones is indicated in cases where there are
more than one ; such a design is relevant only for electric sheets and electric blankets (see "Type") — other types of heaters are not so large that it makes sense to divide them into zones.
The presence of several areas gives additional options for controlling the heater and allows you to more accurately adjust it to the current situation. For example, some people only get cold feet in bed, and only the lower part of the electric sheet is enough to warm up — there is no need to spend energy on the entire area of the heater. As for the specific quantity, most often in "multi-zone" models there are two heating areas — this is quite enough for most cases. Only some double sheets/blankets may have 4 zones — 2 for each sleeper.
Power consumption
Rated power consumed by the heater during operation.
Technically, other things being equal, a more powerful device will heat up faster and heat more greatly, but its energy consumption will also be higher. However, in fact, this parameter is of secondary importance: manufacturers select power in such a way as to provide the heating pad with the necessary performance. So paying attention to power makes sense mainly when comparing and only in cases where the differences are significant — for example, if one model consumes 100 W, and another of similar size only 60 W.
