![]() In addition to room size, it’s a good idea to take price into account. This is a reflection of how different manufacturers rate their equipment and, as they often say in the small print, it should only be used as a guide. There’s a lot of inconsistency in those figures, and they don’t provide a linear progression. If you take an average of the figures provided, you get the following:ġ,000W may heat a room of 100 to 125 sq.ft.ġ,500W may heat a room of 120 to 170 sq.ft.Ģ,000W may heat a room of 60 to 240 sq.ft. Having looked at numerous products, we’ve found most wall heaters range from 750W to 2,000W. ![]() A particular wall heater might heat a 100 sq.ft. Manufacturers often make their own recommendations. HVAC systems generally use BTU (British Thermal Unit) ratings, but unfortunately, few wall heater makers supply figures. This is a tough question, because it depends on how well-insulated your room is and how efficient the heater is. How do I know what size wall heater I need?Ī. The fans in some cheaper wall heaters can be surprisingly noisy. You can then set the heater to come on before you get home, before you get up in the morning, or whenever you want to set it.īefore making your purchase, don’t forget to check the sound level. If you’re buying a plug-in wall heater, think about adding a plug-in timer. If you’re not comfortable with the instructions, call a suitably qualified professional. If you’re installing a hardwired wall heater, make absolutely sure you know what you’re doing. Take note of the manufacturer-suggested safe zone, and be aware that if you place items too close, there’s a risk of fire. Surrounding items can get very hot if they are in the path of the warm air. Tipsīeware of putting items too close to your wall heater. Models of 2,000W from respected manufacturers are around $150, and the most powerful models of 4,000W seldom top $250. While many designs remain quite basic, you don’t really pay a premium for those that are more attractive. You’ll find a variety of power outputs, from 750W to 1,500W, that can provide a cost-effective heating solution. Most of the lower-priced wall-mounted heaters we would recommend fall in the $60 to $100 range. Wall heater pricesĪs we’ve seen, there’s not a great deal of complexity with wall-mounted heaters, so prices tend to reflect the quality of manufacture, power, and the few possible extras. Temperature control: Temperature control is usually a question of “hotter” or “colder” rather than a precise degree value, though some digital units offer this level of accuracy.įrost setting: A frost setting can be used to minimize energy use while ensuring the room never drops below freezing. ![]() After that time elapses, the heater settles at a temperature set by the thermostat. Mounting your wall heater near the center of the room can help combat this problem.īoost controls: Boost controls are available on some models, allowing you to use maximum heat for a predetermined amount of time. The drawback is that some measure the temperature of the unit itself, so if they’re fitted too close to one end of a large room, you might need to set them higher than expected to warm the other end. Wall heater featuresīuilt-in thermostat: Most wall heaters have built-in thermostats. Surface-mounted models usually - though not always - plug into a convenient outlet. Some people have the skills to do this themselves, but it’s always advisable to call a qualified electrician. It’s better, in our opinion, to buy a model designed for surface mounting in the first place if that’s what you want. However, we’re unable to see why you would want to do that. If you don’t like that idea, choose a surface-mounted wall heater, which only requires a few fixing screws.Ī few inset models offer the option of surface mounting, though additional hardware may be required. Having said that, an inset heater requires you to make a hole in your wall if there isn’t one already. Inset wall heaters are usually sized to fit standard gaps in the framework of partitioned walls, so installation is relatively easy. ![]() Wall heater considerationsīefore making your purchase, you must decide how you will mount the wall heater: will it be an inset or surface-mounted appliance? Furthermore, you’ll want to decide how to power your wall heater - via hardwiring or plug-in electricity. A surface-mounted wall heater with plug-in power can be moved easily, leaving just a few small holes to patch up. An inset wall heater make less of a physical impact in a room, but it is a much more permanent fixture. ![]()
