How To Find the Right Heater for My Garage or Workshop
We're often asked, "what is the best way to heat a garage"?, "how can I best heat my workshop"?, or "how do I size a heater for my space?" There are many variables involved in selecting just the right heater or heaters to meet your specific criteria.
To choose the correct size of heater for your garage or shop space, begin by asking the following:
- How big is the space to be heated (square footage and ceiling height)?
- What is the building constructed of? Steel, Wood, Brick?
- How well is the space insulated? Insulated walls, ceiling, overhead doors, etc.?
- What is the climate in your area? Northern climate? Southern climate?
- What fuel do you have available? Natural or LP gas? Electricity only?
Once these questions are answered, it's just a matter of doing a quick heat loss calculation to come up with the BTU heat load requirement needed to do the job effectively.
So how do I conduct a heat-loss calculation? Simple. You don't. A qualified heating professional – usually a heating equipment distributor – can do that for you.
Once you've determined the actual heat load requirement for your given space, the next step is to search out the various heater types and heater methods available in the marketplace.
Are you looking for a portable heater or a fixed heater? Forced air or radiant (infrared)? Vented or vent-free? Don't know for sure? Then get on the internet and begin searching. Type into your browser such keywords as:
- "garage heater"
- "workshop heater"
- "forced air heater"
- "gas infrared heater"
- "electric garage heater"
- "infrared tube heater"
- "vent free heater"
Searching keywords and phrases with any combination of the above will get you well on the road to viewing a lot of options from a lot of manufacturers.
Next, search from companies that specialize in the type of heater or heating products that you feel would be best suited to your application. This is critical. A little research can pay off big. After-all, not all heater manufacturer's are alike. There can be substantial differences between brands, heater quality, warranties, return policies, etc.
Once you've narrowed down your search, do a few phone interviews. Find out more about the company you in tend to buy from. Of course you want a good heater. But buying from a reputable re-seller is paramount. Find a company with the strength, reputation and staying power to offer you whatever support you may need in the short term in addition to years down the road. Nothing is more frustrating than purchasing a product online, then finding that company has suddenly disappeared, with no way to get future customer support.

Water heater vent size?
What is the maximum size vent that can be used with a 40000 BTU water heater? We just got a high-efficiency boiler installed which vents directly thru the side-wall.
We also replaced the old 63000 BTU water heater with a new 40000 BTU model. The draft hood of the new water heater is only 3 inches in diameter. The new water heater is now the only thing that is venting thru the old 20 foot long venting pipe to the roof, which is 6 or 7 inches in diameter. Is this too big to vent properly? How difficult is it to install a smaller diameter liner into the old pipe?
The 30 , 40 or 50 gallon water heater (non comercial) only needs a 3 in. i.d. pipe they do make a reducer from 6in to 3in the pipe should run vertical as much as possable. 6 inch pipe would cause the exhust to flow slowly and may cause problems in high wind areas.
Our local codes wont allow the use of side vents through the walls but in your area they may.
The installation manual with the heater should tell what vent sizing is acceptable with that particular heater.
You may try a test fit of the new pipe as some of the (brands) pipes are differant in O.D. you may luck out and be able to slip the new pipe inside .
