Over the Door Electric Heater

Posted by GreenDog194 (My Page) on

We are building a studio shed in the back yard. We need heat. Baseboard heaters don't work for us because it is a small space and we will need to put things against the walls. Wall heaters don't work either for the same reason. There is only one tiny potential space to maybe put a toe kick heater, but the space will see a bunch of dirt and wear -- toe kick level seems like an invitation to problems. Hanging shop heaters seem too temporary, and the ceiling is 9 feet high, so reaching the dial would not be possible.

I found the perfect solution -- heater for over the door. http://www.convectair.ca/caen/produit/soprano.html However, at 9 inches high it is too high for the header between the door and the clerestory window above the door. The other walls are windows or bookcase / wall storage.

There are narrower (about 6 inches) over the door heaters, such as this one, but they only seem to be sold in Europe: http://www.mas-uk.com/manufacturers/quantum-heaters-30/

Are there similar items sold in the US?

Thanks for your help!

Have you considered a mini split system? You can get heat only or heating and cooling. You can get a system with a remote control so you can mount it high on the wall and not have to reach. There are other manufacturers which make similar products.

Here is a link that might be useful: Mitsubishi mini split

This is new to me, thanks. We live in Seattle, and the studio has lots of windows, not sure we need AC. But, maybe it is nice to have. I don't understand the system -- seems to have an inside component and and outside component: http://www.mitsubishipro.com/media/382145/slim-m-series_contrguide.pdf

Also, seems to be 11" tall -- taller than the Soprano, which is too tall to fit on the header between the door and the clerestory window.

I'm not sure I read the tech specs correctly, however.

What can you tell me about these?

Mini splits: One way to look at it is you cut a window unit in half. Install the heavy, noisy part outside on the ground, and the light, quiet part inside. You can install ceiling heat exchangers as well as the wall-mounts. It is not going to be cheap.

Check the consumer-oriented web sites at Mitsubishi, Panasonic, Fujitsi, Toshiba,...

I don't understand the problem with "hanging shop heaters". You should be able to install a control pretty much anywhere you want.

Markel/TPI makes all sorts of electric heaters.
I googled markel heater and this is one site that came that sells them.

They can have a thermostat. This company makes probably 500-1000 different models.

A minisplit would also be a good option if you would use the cooling.

By "minisplit" you mean a ductless heat pump? If so I can tell you we had a Mitsubishi system installed when we divided an 1,800 square foot studio building into a 600 sf studio and 1,200 sf shop. Each space has its own wireless thermostat. The wall units are mounted about 9' from the floor. The only limiting factor is that the interior units need to be mounted on the wall adjacent to the exterior heat pump. The system works very well.

Mini splits, as they are often called, are most often duct-free. Several types of indoor units are available in addition to the most common high wall mounted including ceiling cassettes, floor-mounted units, and minimally-ducted air handlers that can service more than one room.

If "adjacent to the exterior heat pump" means ca. 80 linear feet, then, yes, that is limiting. In addition, there are elevation limitations.

The installation elevation limitations for linear pipe length for a Mitsubishi MXZ-2B20NA (dual) are excerpted below.

Piping length each indoor unit (a, b) 82 ft. MAX.
Total piping length (a+b) 164 ft. MAX.
Bending point for each unit 25 MAX.
Total bending point 50 MAX.
