Best Wall Heaters - Complete Buying Guide

Wall heaters are essentially heating units that are mounted, attached or built right into the wall of the room that they are placed in. They are generally fuelled by natural gas, though some people often choose propane gas or electricity to power their wall heaters, albeit less frequently than natural gas is used. Wall heaters are known for their space saving design, and are generally placed close to the floor, allowing warm air to rise up and warm the entire room.

Wall heaters are generally made out of metal, and contain heating elements such as porcelain bricks or metal coils. The heat is often expelled through a fan, which results in an even distribution of air across the room. However, it is often found that, when using heaters that expel hot air using a fan, the warm air tends to stay on the floor level, as that is where such heaters are usually placed. A fair amount of heat manages to rise to the top, but most of it does not manage to do so, circulating instead at the bottom of the floor. This results in an uneven distribution of heat across the height of the room, good heat distribution across the width of the room notwithstanding. Such heaters are also often not very safe, and must be cleaned regularly in order to maintain longevity and prevent fire hazards.

Another type of wall heater is the baseboard heater. A baseboard heater is a throwback to the days of cast iron heaters that propagated warmth through radiation of air away from the heating element, but in a more sleek, low profile design that contributes to a more modern look. This kind of heater produces heat via resistance, i.e. electricity is forced into a circuit in which a resistor has been placed, and the resistor’s presence turns the electricity into heat which is then radiated through the openings in the heaters design. Baseboard heaters tend to radiate heat well across the height of the wall, leading to a good vertical distribution of heat, but tend not to get heat across the width of the room very well. Baseboard heaters are generally safer than fan heaters, though they tend to be unsafe for children due to the openings in the body that lead directly to the heating element.

It is highly recommended that the heater be inspected by professionals on a regular basis, as this can greatly reduce the chances of accidental fires caused by malfunctions. Gas lines providing natural gas to the heaters should be closed during periods of extended non-use as an added precaution.
