deciding on a garage heater

[pixelmonkey]

It seems the workers at the local hardware stores come equipped with shelf stocking knowledge... and nothing more.

Hope you guys can help me out with the best option for garage heat.

- 2 car garage
- insulated 16' over-head garage door
- insulated and sheet rock walls
- concrete floor
- 110 electric outlet available *no 220 present*
- NO ventilation

I would like a heater to heat the garage in about 30 minutes and keep things around 50 - 60 deg F when it's freezing outside. The garage door has extra seals at each gap to prevent air flow from the outside.

The only ventilation will be when I open the over-head *garage* door.

Suggestions?
I've been thinking about something like a kerosene heater, but not sure if ventilation is needed.

I'd recommend a Rinnai EX38. 82% eff, direct vent (3" hole thru the wall for the vent), modulating gas valve and blower, programmable stat built in. When it was 0* I could go down to the cold garage, start the heater, have breakfast and be comfortable for the rest of the day. Mine was a 24 x 24 x 8, block wall, leaky doors, no insulation. LP or NG. Depending upon the type work you are doing you will have a different maintenance schedule. I did automoticve but also woodworking in my garage. I had primary and secondary dust collection. Clean the supplied filter as needed. Annually, I'd take the cover off (two screws) and clean the blower wheel and generally blow dust and debris out of the vestibule. 95% of the Rinnai's I sold in '91 are still in the field. these are not inexpensive, but you get your money's worth. Simple install. 1/2" gas line and 110v GROUNDED outlet

My disclaimer! I represented Rinnai for 20 yrs., sold over 180,000 of these things and they are just outstanding. I heat my house with them and will heat the garage with them...once I build it!

Kero- noisy, dirty, lots of fumes, quick and easy. Kero stinks like **** when you spill it in the garage or in the car/truck transporting it.

Do you have natural gas present?

If so, I suggest against radiant heaters. Go with a small forced air furnace powered by gas if possible.

Good Luck!
