Runtal Electric Wall Panel Heater 1 of 3

Hi, I'm Tim Carter. Ask the Builder. And I'm going to explain to you today how to size residential electric space heaters

And it's really, really important to know how to do it the right way. And this is video one of a three-part series

And today I'm just going to talk a little bit about sizing the heaters, how you make that calculation

Video number two, we're going to show putting them in. Video number three, you're going to see how beautiful they look once it's all done

room's done. But right now, just so you know, this is a giant basement remodel project. I'm standing

in what's going to be the television room right behind me. Once this is done, it's going to be a huge

flat screen TV. There's a bedroom down here. There's a game room. We've got an old speakeasy wet bar

and a full bathroom. So it's a big project. In each one of those rooms is going to have its own

heater. But right now, let's talk about how to size the heaters for this particular TV. Room

Step one of the process is we have to measure the room because that tells us how many square feet we have to heat

And there's kind of a general rule of thumb of 20 to 25 BTU

per square foot of area of the room. And that's kind of a funny number

Here's why. You don't need as much heat if the room that you're trying to heat

is say in southern or middle Georgia or, you know, Arkansas. But if that same room is up in New Hampshire, where I am

or maybe northern Minnesota, you're going to need more heat because it's colder outside in the wintertime

So if it's colder where you live or where you're going to put this heater

stay closer to that 25 number, all right? That's what I would recommend if it's really cold, like northern Minnesota

Because my house here that we working in is so well insulated I going to go with the 20 BTU number So let me show you how we calculate it Look here

So I measured the room, and the room is 20 feet long this way, and it's 15 feet wide

So 20 times 15 is 300 square feet. And once again, remember I told you the 20 to 25 BTUs per square foot

we're going to use the 20 number. So 20 times 300 is 6,000 BTUs

So I need 6,000 BTUs to heat this room. And guess what

It just so happens. The rental wall heaters that we're using, they have one perfectly matched that produces 3,000 BTUs

So we're going to put two of those in. Let me show you where we're going to put them. As I just told you, we're going to put in two of the Rental Elections

wall panels. These are beautiful sleek heaters that attach to the wall. They're very thin

They don't protrude out very much. Wait till you see them. Don't worry. You're going to see

that in the next video But they going to go on the outside wall It really important where to place them This is the outside wall of this basement here And we already put three quarters of an inch of foam insulation on the concrete wall We going to fill this cavity with fiberglass

And you want to put the heat always on an outside wall. You want to flood that wall with the heat

It's super important. Here's what I want to show you. One heater is going to go right here

and we've already put in this blocking for it, so we've got solid blocking

The heaters are going to be about 36 inches wide. We're going to have ours about 4 inches off the floor

And when you get the installation instructions, they show you where to rough out the electric cable for the heater

All right? We're using 120-volt heaters. They have different voltage options. You can look into that when you look at your electric heater

manufacturer or if you go to Runtle they've got all this information for you

Let me show you where the second heater is going to go. Same exact setup, same

exact blocking. So we've got solid blocking to attach the heater to. We know

where this is. Here's the 120 volt line roughed in at the perfect height for this
