I’m looking at ceiling mount electric heaters for my shop. The shop is about 15 X 20, pretty well insulated.

Any thoughts on this one? Is it overkill?

BTW – I can get it for around $275 with free shipping via ebay.

I looked at both the G73 and the G70. Both require 240 direct wired boxes but I bet a electrician tells you it can be done with a drier plug just to make it easier to put in, and remove if you had to. Both have plenty of heat capability. I see you are in Indiana and it gets under 32F for long periods of time so I will not recommend a heat pump as you would not be happy. Down south here in Ga I have a heat pump and it works well for both seasons. My friend has a G70 in his 20×20 shop and it does keep it nice and warm, warm enough he works in shorts and a tee shirt year round.

Go to a BTU calculator such as this one: http://www.hearth.com/calc/btucalc.html and load your data. It will tell you the BTU range you need, then see if the heater you are looking at will do the job you want.

Rule of thumb i learned as an apprentice is 10 watts per square foot. It should be plenty.

Here’s a pretty nice calculator that converts BTU to Watts. You don’t want you heater undersized or oversize.

woodbutcherbynight, I’m in Indiana, as well, and I heat my home with a heat pump. I am happy with it.

I have one of those heaters (Dayton label) and it works fine. When I bought this place, the shop was 16×24 and it heated fine (we’re about the same latitude, I’m just a little east of you).

I got a Farenheat unit from Northern Tool for 299. (was cheaper 4 years ago) but is still their #1 seller for garage heating.

My shop is 14X21 with 12 foot ceiling, and I have never run the unit more than 50%.

I SPECIFICALLY chose a unit that did NOT have any exposed heater filament wire that would be a fire danger. The elements are fully enclosed, so won’t ignite any vapors or sawdust. So look at the filaments in whatever you choose.


Product Details

Heats things up fast AND saves floor space! No blast of cold air at start-up — automatically delays fan action until the long-life heating element is warm. Fan continues until the heating element cools off. Built-in thermostat. Powerful heater delivers up to 17,065 BTU/hr. Horizontal heat flow and adjustable downflow positions allow it to distribute heat evenly throughout the room. Plated fin heating element provides uniform heated air discharge. 14in.L x 12 1/2in.W x 12 3/8in.H. 240 Volts, 5000 Watts at 17,065 BTU/hr. 21 Amps. Ceiling mount bracket included. U.S.A.

Ron – I thought about baseboard heaters, but was worried about sawdust – I don’t have a collector and am VERY bad about sweeping up.

Nice tip, DrDirt. I guess I look at this model about a year ago and forgot about it. Looks like a good price and gets great reviews.

Yeah doc – - I chose this because contrary to some recomendations, I spray with an HVLP gun sometimes.

Just usually the little boxes and such, and open the garage door, but try to avoid having a hot ignitions source.

I have the Farenheat model as the main source of heat for my 17×30 shop; it keeps the shop comfortable even on the -30 days…
