Recommends for Electric Ceiling Mount Heater

[Yankee2bbq]

My shop size: 18 ft wide, 40 ft long. 12 foot walls, open ceiling. (Common gable 4:12 pitch). Foam insulation. No windows, insulated overhead garage door.

Currently looking at a 7,500 watt, 25,589 btu unit.

Is this sufficient enough?
Not going to heat the shop 24/7. Only when I’m in there working at a heated temperature of around 50 degrees.

Any thoughts or advice is wanted. Thanks

I think it might be hard to get heat across the full 40', maybe do two heaters?

Also - be prepared for high electric bills!

It should heat it, unless it is poorly insulated, but keep in mind it may take a couple hours to get to set temp.

Add couple of ceiling fans to help push the heat down.

I heated a well insulated 18' x 34' space with a 12ft ceiling with a 7500 on low last winter. I believe it is a Comfort Zone CZ230ER.

The problem will come from the heaters ability to bring the shop up to temp in short order. While it might be able to maintain a certain temp, it might take a while for a smaller heater to heat a larger space.

For example if you want to be out in your shop within an hour and expect it to be 50, that might not happen. Might have to wait 3-4 hours? Versus a larger heater getting it up to temp faster, but possibly being overkill for the space if you were going to maintain a temp.

Open ceiling, as in no ceiling?

My 16x20 shed is like that. It's slightly better than heating the outdoors since the heat goes out the roof vents.

No ceiling. I have no roof vents. Spray foam everywhere.

I have a Comfort Zone CZ230ER in my 1000sqft 10ft ceiling well insulted attached garage. It has no problem bring the temp up from around 40 to low 50's in an less than 2 hours. I also turn on the shop ceiling mounted air filter at the same time to help circulate the hot air from up high.

Only issue I have had with the heater is when I first installed it there was problem with short cycling. Would run for 1-2 min then shut down due to overheat. Found there are 2 installed thermal cutouts 1 for the room temp and 1 for unit overheat. They where swapped from the factory, same 2 wire plug size on the circuit board so just swapped them and no issues since.

I am researching the same thing but I was also looking at a wall mounted heater.

Such as:

Cadet 240/208-volt 4,000/3,000-watt Com-Pak Twin In-wall Fan-forced Electric Heater in White with Thermostat CSTC402TW - The Home Depot

This energy efficient Cadet Com-Pak Twin Fan-Forced In-Wall Electric Heater in White is powerful enough to use in commercial lobbies and entryways.

I know the watts are lower but I was thinking it would keep a little more heat out of the ceiling.

I realize this thread is for ceiling mount but let me know your thoughts on wall mount too.

You might want to check out quartz heaters.

Hot Air rises!
Whether the heater is in the wall or ceiling mounted, any and all heat will naturally rise!
Ceiling fans will help push it back down.

Berko and QMark are pretty much the industry standard for electric unit heaters: https://www.marleymep.com (click on Brands in the upper left hand corner.)
