you can use infrared wall mounted infrared space heater in your garage. I am using Dr. Infrared Heater for 3 years. it warms my 900 sq ft garage very quickly. 

 

MODERATOR COMMENT:  This thread was about permanently installed fuel fired space heater mounted on the wall. This post is someone's experience about using a portable electric heater (not a fuel-fired heater).

I know it's an old thread, but maybe it will be a timely resurrection for someone

I hate to throw an additional wrench into this thread, but I just read it this morning...

Now that the space is heated (conditioned), in my jurisdiction it would have to pass the IECC building envelope requirements. The garage must be insulated, and I''m curious how the overhead door would meet the fenestration requirements in the IECC for leakage. Guess what... this is now HEATED space as defined in the IECC, not a garage, and consequently must comply.

Much Thanks "Uncle Bob" and "skdryer" for your input.

I don''t have an answer that will provide heat for the pets and have the space heater in a convenient location. Telling the homeowner that he will have to put the space heater at least 6 ft. up probably won''t cut it. I''m still trying to come up with some type of permanent barrier that the homeowner can install so the vehicles won''t run into it. The space heaters that I have seen ( in the Commercial repair shops ) come to mind.

Anyhoo, thanks for your input. 🙂

I don''t think that I can go having "rats" around as pets, irregardless of how good their social etiquette is. 😀

[b]A Side Story:[/b] Years ago, when I was stationed at Guantanano Bay, Cuba, some people would go down to the base dump and have target practice on the furry critters as something to do.
Boy, ...they sure were bored! Surprised

it is allowed to have a furnace, water heater, unit heater,in a garage. not considered hazardous conditions we do it all the time pilot has to be raised 18" above floor this allows for the fumes to linger underneath the unit i would not want to see a ventless heater in a garage but it would be allowed if all requirements r made

Ok,

M1702.1 Required volume. (combustion air)

Where the volume of the space in which fuel-burning appliances are installed is greater than 50 cubic feet per 1,000 Btu/h of aggregate input rating in buildings of ordinary tightness, insofar as infiltration is concered, normal infiltration shall be regarded as adequate to provide combustion air.

You have 28,000 Btu/h? and 3,308 cu. ft..

50 X 28 = 1400 cu. ft.; so you have plenty of combustion air; and with the air from around the garage door you should be good to go for normal infiltration.

The only thing I can think of the prevent the installation is:

M1701.4 Prohibited sources. 2nd sentence;

Combustion air shall not be obtained from an area in which flammable vapors present a hazard.

(Kind of hard to enforce if a gas-fired water heater is already in the garage; or if they are allowed in garages; and they are).

I have tried pleading; and, sometimes it worked. If they are going to leave the cars outside to prevent the poor puppies from being asphixiated from the auto exhaust fumes; they do make a doggy electric heating pad for dog houses. The problem with suggesting something is that should the doggies be electricuted or a short burns down the house; guess who''s it. You might suggest that they go to PetSmart or a similar pet store for advise on what is best for the poor little puppies locked in the mean ole garage. They may have a better solution. I find them very helpful. I have a daughter (at University) who has periodically; stuck me with a hamster; then two rats; and then three Parakeets. By the way; rats really like people and are very affectionate 😀 .

Uncle Bob,

Thanks for the reply! I DID read both of those sections that you listed. I was / am hoping that someone on here will provide some clarity that will allow or dis-allow this particular installation. Such as: [b](1)[/b] The required volume of combustible air in this garage for this size of space heater, or [b](2)[/b] Because of the possible storage of flammable fumes / vapors from vehicles, spills, etc., that this space ( in a private garage ) will be considered a hazardous space, and therefore, NOT allow the installation.

What is the ratio of required combustible air to BTU''s for this appliance ?

Is there anything in the IFC ? or the Life Safety Codes ( although we don''t officially enforce the Life Safety Codes, but occasionally DO reference them ) ?

Still seeking ya''lls "much valued" input. 🙂

Even had the plumber call our department and ask about potentially hazardous installation in this enclosed garage ( it DOES have an openable door on it, otherwise sealed on three sides ).
