5 Best Wall Heaters - Aug. 2022 - BestReviews (2022)

Are you looking for a convenient way to deliver extra heat to your home? Some households rely on a wall heater for supplemental heat. Wall heaters offer several important advantages. When there’s a chill in the air, you can heat a single room rather than turning up the heat for the whole house. The heat is nearly instant, whereas underfloor heating and HVAC systems take time to warm up. And, of course, a wall heater doesn’t consume valuable floor space.

Most wall heaters have a built-in thermostat that you can use to fine-tune the warmth in the room or rooms of your choice. Bathrooms and bedrooms are common locations. So how do they work? Inside the wall heater casing is a heating element. As soon as you hit the switch, you get heat. To spread the heat around the room as quickly as possible, a fan is included. The fan blows cold air across the element and warm air into the room. Wall heaters are simple, reliable, and fast.

An inset wall heater make less of a physical impact in a room, but it is a much more permanent fixture. A surface-mounted wall heater with plug-in power can be moved easily, leaving just a few small holes to patch up.

Wall heater considerations

Before 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.

Inset vs. surface-mounted wall heaters

Inset wall heaters are usually sized to fit standard gaps in the framework of partitioned walls, so installation is relatively easy. Having said that, an inset heater requires you to make a hole in your wall if there isn’t one already. If you don’t like that idea, choose a surface-mounted wall heater, which only requires a few fixing screws.

A few inset models offer the option of surface mounting, though additional hardware may be required. However, we’re unable to see why you would want to do that. It’s better, in our opinion, to buy a model designed for surface mounting in the first place if that’s what you want.

Hardwiring vs. wall plug

Inset heaters are invariably hardwired. Some people have the skills to do this themselves, but it’s always advisable to call a qualified electrician. Surface-mounted models usually — though not always — plug into a convenient outlet.

Wall heater features

Built-in thermostat: Most wall heaters have built-in thermostats. 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. Mounting your wall heater near the center of the room can help combat this problem.

Boost controls: Boost controls are available on some models, allowing you to use maximum heat for a predetermined amount of time. After that time elapses, the heater settles at a temperature set by the thermostat.

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.

Frost setting: A frost setting can be used to minimize energy use while ensuring the room never drops below freezing.

Wall heater prices

As 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.

Most of the lower-priced wall-mounted heaters we would recommend fall in the $60 to $100 range. You’ll find a variety of power outputs, from 750W to 1,500W, that can provide a cost-effective heating solution.

While many designs remain quite basic, you don’t really pay a premium for those that are more attractive. Models of 2,000W from respected manufacturers are around $150, and the most powerful models of 4,000W seldom top $250.

Before making your purchase, don’t forget to check the sound level. The fans in some cheaper wall heaters can be surprisingly noisy.

Q. How do I know what size wall heater I need?

A. This is a tough question, because it depends on how well-insulated your room is and how efficient the heater is. HVAC systems generally use BTU (British Thermal Unit) ratings, but unfortunately, few wall heater makers supply figures. Manufacturers often make their own recommendations. A particular wall heater might heat a 100 sq.ft. room, for example.

Having looked at numerous products, we’ve found most wall heaters range from 750W to 2,000W. If you take an average of the figures provided, you get the following:

There’s a lot of inconsistency in those figures, and they don’t provide a linear progression. 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.

In addition to room size, it’s a good idea to take price into account. If you’re caught between two sizes and can afford the more powerful model, that’s the one we would choose.

Q. Are wall heaters expensive to run?

A. It can be argued that wall heaters are not as efficient as whole-home HVAC or underfloor heating. Furthermore, they don’t provide the residual warmth that radiators do; as soon as it’s off, a wall heater stops delivering heat.

However, as a solution for warming modest spaces, this option is tough to beat. Wall heaters themselves are relatively inexpensive to buy and install. A wall heater with a built-in thermostat helps conserve energy, and other features (such as timers and other control devices) can be attached. You enjoy the ability to heat one or two rooms rather than the whole house — and that will save you money.

Q. What’s the difference between a radiant heater and a convection heater?

A. Radiant heaters heat objects, including people, whereas convection heaters heat the air. For instance, an outdoor patio heater that works with radiant heat is a good idea because if you stand near it, it’s like heating yourself in front of a fireplace. But radiant heat is not such a good way to heat an enclosed space, because if there’s a chair between you and the heat source, the chair will absorb much of the warmth.

Almost all wall heaters use convection heat to warm the whole room evenly. There are no cold spots. The convection effect doesn’t absolutely require a fan, though a fan can help speed up air circulation and thus warm the room more quickly.
