Heater for a 2-Car Garage: Your Essential Buying Guide
A two-car garage can be a cold, miserable place, especially in winter. Whether you work on cars, use it as a workshop, or just want to grab your groceries without freezing, finding the right heater is key. This guide helps you pick the best one.
Key Features to Look For
When shopping for a garage heater, certain features make a big difference in performance and safety.
Heating Power (BTUs)
The most important thing is how much heat the unit puts out. This is measured in British Thermal Units (BTUs). For a standard two-car garage (about 400 to 500 square feet), you generally need a heater that provides between 20,000 and 40,000 BTUs. Measure your garage space first! A heater that is too small won’t warm the area effectively.
Fuel Type Options
Heaters run on different fuels. Each has pros and cons:
- Electric: Easy to install. Great for smaller spaces or supplemental heat. They cost more to run if electricity prices are high.
- Propane (LP Gas): Very powerful and portable. Good for quick, intense heat. You must ensure good ventilation because they produce combustion byproducts.
- Natural Gas (NG): Usually the cheapest to operate if you have a line run to your garage. Installation requires a professional.
Safety Features
Since garages can store chemicals or fuel, safety is non-negotiable. Look for:
- Automatic Shut-off: The heater turns off if it tips over.
- Oxygen Depletion Sensor (ODS): This shuts the unit down if oxygen levels drop too low (important for fuel-burning units).
- Overheat Protection: Prevents the unit from getting too hot and causing a fire.
Important Materials and Construction
The quality of materials affects how long your heater lasts and how safely it operates.
Heating Elements and Burners
For electric models, durable metal heating elements last longer than plastic ones. For gas models, solid steel burners handle high heat better. High-quality construction means the metal resists rust and corrosion, which is common in damp garages.
Housing and Durability
A good garage heater needs a tough exterior. Look for heavy-gauge steel housing. This protects the inner workings from accidental bumps from tools or vehicles. Powder-coated finishes resist chipping and rust.
Factors That Improve or Reduce Quality
The overall user experience depends heavily on how the heater is designed.
Factors That Improve Quality
- Thermostat Control: A built-in thermostat lets you set a specific temperature. This saves energy because the heater only runs when needed.
- Portability/Mounting Options: Some heaters sit on the floor; others mount high on the wall. Wall-mounted units keep the floor clear, which improves safety and space usage.
- Quiet Operation: Fans on electric heaters can be noisy. Look for models specifically designed for quieter operation if you spend long hours nearby.
Factors That Reduce Quality
Cheap heaters often skip essential components. Units without proper insulation lose heat quickly, making them inefficient. Also, heaters that lack clear, easy-to-read controls frustrate users quickly.
User Experience and Use Cases
Think about how you actually use your garage. This dictates the best heater type for you.
Workshop Use
If you spend hours woodworking or fixing cars, you need consistent, even heat. A permanently installed natural gas or propane heater with a thermostat works best here. You want the heat to stay steady while you work.
Temporary or Quick Heat
Do you just need to defrost the car quickly or warm up the space for 30 minutes? A portable propane “salamander” style heater or a high-powered electric radiant heater works well. These heat up fast but might not maintain a consistent temperature over many hours.
Ventilation Requirements
Always remember: Fuel-burning heaters (propane, natural gas) produce exhaust gases like carbon monoxide. You must install these according to local codes and ensure adequate fresh air intake. Electric heaters do not require ventilation, making them safer indoors but often less powerful.
10 Frequently Asked Questions (FAQ) About Garage Heaters
Q: What size heater do I need for a standard 2-car garage?
A: For an average 20×20 foot garage (400 sq ft), aim for a heater rated between 20,000 and 30,000 BTUs for comfortable warmth.
Q: Can I use a regular indoor space heater in my garage?
A: It is generally not recommended. Garage heaters are built tougher to handle dust, temperature swings, and sometimes moisture. Indoor units often lack the necessary safety features for a garage environment.
Q: Is propane or natural gas better for a garage heater?
A: Natural gas is usually cheaper to run if you have a supply line. Propane is better if you need portability or do not have access to a gas line.
Q: How much does it cost to run a 5,000-watt electric garage heater?
A: This depends on your local electricity rate, but a 5,000-watt unit draws a lot of power. It can be expensive to run continuously compared to gas options.
Q: Do I need a special outlet for an electric garage heater?
A: Yes. Most high-BTU electric heaters require a dedicated 240-volt circuit, similar to an electric dryer or range, not a standard 120-volt wall outlet.
Q: Are infrared (radiant) heaters good for garages?
A: Yes. Radiant heaters warm objects and people directly, not the air. This is great if you are working in one spot and want instant warmth without waiting for the whole room to heat up.
Q: What is the biggest safety concern with propane garage heaters?
A: The biggest concern is carbon monoxide poisoning. You must always ensure proper ventilation when burning propane indoors.
Q: How high should I mount a ceiling-mounted heater?
A: Follow the manufacturer’s instructions carefully. Generally, they must be mounted several feet away from combustible materials like wood rafters or stored items.
Q: What level of insulation affects heater choice?
A: A well-insulated garage needs less powerful heating (lower BTUs). A poorly insulated garage with high ceilings needs a much stronger heater to overcome constant heat loss.
Q: Can I use a heater outside my garage door to keep the entrance warm?
A: Only use heaters explicitly rated for outdoor or wet conditions. Most indoor/garage heaters are not weather-resistant and could short circuit or catch fire if exposed to rain or snow.
