Heating area
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.
Installation
Installation methods, nominally provided for by the design of the heater. Many models allow several mounting options — for example, floor or wall, at the request of the user.
— Floor. Installation directly on the floor using feet, wheels or similar supports. Such installation is as simple and fast as possible — no work is needed, it is enough to find a free area of the floor and install a heater on it. Accordingly, moving from place to place is also not a problem — especially if the design has the wheels mentioned (and almost all heavy devices like oil heaters are equipped with them). And you can place the heater almost anywhere in the room — with certain restrictions, but the freedom of movement for such devices is still much greater than for wall or ceiling ones. At the same time, a floor heater takes up the most space, and there is also a risk of bumping into such a device and tipping it over.
— Wall mounted. Mounting on a wall, usually by hanging on hooks, screws or other similar devices. This installation option is found in all types of heaters, but it is most popular in convectors and fan heaters. Wall installation is not as convenient as floor installation — certain work is required to prepare the wall, and it is impossible to install such a device in the middle of the room. On the other hand, wall models do not take up space on the floor, which can be especially useful in cramped conditions.
— Ceiling. Installation by hanging from t...he ceiling. This option is used mainly among IR heaters — installation at the maximum height allows you to cover a large area; in other types of heaters, ceiling mounting is practically not found. Often, ceiling models also allow wall installation.
— Into socket. Portable heaters with a plug directly in the housing are installed in the socket. The dimensions of such devices are negligible, as well as the heating power. Plug-in models are a good option for heating a workplace in a small office space, at a guard post or in a gatehouse.
Note that accessories for a particular type of installation may not be included in the kit, they will have to be purchased separately: for example, for a wall-mounted convector, you will need to purchase screws or other fasteners, and for a floor convector, legs-stands.
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.
