Mike Dunn: Hi! I am Mike Dunn with Stiebel Eltron. Today, I am going to provide you with some tips on how to choose a wall-mounted electric space heater for your home or office.
This type of electrical space heater is available either as a fan heater or as a convection heater. Each type has advantages and there are many things to consider in choosing which one is right for you.
A fan heater uses a small fan to pull cool room air in and blow warm air out. This design warms floors and creates an even circulation as heat rises. It's perfect for quickly adding a little extra heat to a room or space, such as in a hallway, a small bedroom or bathroom or even the primary heat source.
There are several things to look for when choosing a wall-mounted fan heater. One is how does it mount? Is it a surface mount or does it need to be recessed into the wall which is a little more difficult to install. You also need to know the heater's electrical requirements. Does it need a 120 V or 240 V, and does it need to be hardwired or can it be plugged into an outlet?
Make sure the model you are looking for can provide enough heat for the space. You don't want to put in a heater that is too small as the room will be too cold. A heater that is too large for a space and doesn't had a thermostat will make the room too hot.
A rule of thumb is 10 Watts of heating power for every square foot of room. For example 1500 Watt heater would work well in a bedroom that is 10 foot by 15 foot or 150 square feet. Typically only one of this type of heaters installed in space but more than one fan heater could be installed in a larger room. Because these types of heaters use a fan make sure it is quiet enough. You don't want to put a noisy heater into a bedroom.
The other surface mounted heater is a Convection Heater. This type of heater has no fan does it work through the natural process of convection.
As air is heated it naturally rises out of the top and cooler room air is pulled into the bottom to be heated. If a room is small enough one of these heaters could provide all the heat needed. But it's easy to replace multiple convection heaters in the same room if necessary to heat a larger space.
Surface mounted convection heaters can also replace baseboard heating. Features to look for when choosing a convection heater are similar to the fan heater. It has an easily installed surface mount or its installation more difficult. And again, make sure you know its electrical requirements; 120 Volt or 240 Volt.
Since convection heaters don't have fans noise is not an issue.
Now that you know the differences between the fan and a convection heater you can make the right selection for your home or office.
