Installing wall heater under a window
Upgrading to a wall heater will give you more wall space, options for furniture placement and a more rapid heat up than with a standard electric baseboard heater. OK, so this headline is slightly misleading without proper context. In general we recommend that you install a wall heater on an inside wall. The one exception? If you're upgrading from a baseboard heater. Chances are if you're upgrading from a baseboard, that heater was installed on an outside wall under a window. That's because when baseboards are installed under a window, they work with the natural flow of air inside a room to spread heat. The gist is that cold air from the window mixes with warm air rising out of the baseboard, that warm air moves around the room, cools and sinks back to the floor, where it is eventually re-heated by the baseboards. That's why it's always best to install a baseboard under a window, according to Craig Peterson, our Vice President of Engineering.
We suggest you install a wall heater on an inside wall because you're not cutting into a stud cavity filled with insulation. But here's the thing: A wall heater gives you more space to place your furniture and is much better at quickly heating up a room than a baseboard heater. The fan inside the heater will also help spread warm air through the room, so the natural airflow isn't quite as big of a concern. It's a big upgrade in a compact package. We want to make sure that the upgrade process is an easy one. If you move the wires to an inside wall, you're talking about expensive and potentially time-consuming re-wiring process for you or your electrician. You already have wires running to the outside wall where the baseboard was installed, so just use those wires to install your new wall heater.
The only thing you'll need to worry about is clearance requirements, which can be found in your owner's guide. The biggest thing to watch out for, according to Steve from our Tech Support department, is drapes and other window coverings. Also make sure that your heater isn't blocked by an open door or has an electrical outlet over the heater. And of course, if you ever have any questions, just give us a call, send an e-mail or start a live chat. We're happy to help make sure your upgrade process is smooth and you are happy with your new wall heater.
