The Ultimate Guide to Buying the Best Garage Heater
Garages are great for cars, tools, and storage. But when the weather gets cold, working in a chilly garage becomes tough. A good garage heater can change everything. This guide helps you pick the right one.
Key Features to Look For
When you shop for a garage heater, certain features make a big difference in comfort and safety.
Heating Power (BTUs)
The most important thing is heating power, measured in BTUs (British Thermal Units). You need enough power to heat your space.
- Small Garage (1-2 Cars): Look for heaters around 15,000 to 30,000 BTUs.
- Large Garage or Workshop: You might need 40,000 BTUs or more.
Fuel Type
Heaters run on different fuels. Your choice affects cost and convenience.
- Electric Heaters: These are easy to use. Plug them in, and they work. They are best for smaller spaces or occasional use. They can be expensive to run for long periods.
- Propane/Natural Gas Heaters: These offer powerful, fast heat. They are great for large, drafty garages. You need a gas line or propane tanks.
- Kerosene/Diesel Heaters: These are very powerful. They produce some smell and require careful handling of fuel.
Safety Features
Safety is never optional. Good heaters include important safety tools.
- Automatic Shut-off: The heater turns off if it gets too hot.
- Tip-Over Protection: The unit shuts down if someone knocks it over.
- Oxygen Depletion Sensor (ODS): This is crucial for fuel-burning heaters. It shuts off the unit if oxygen levels drop too low.
Important Materials and Build Quality
The materials used determine how long your heater lasts and how well it handles the rough garage environment.
Housing and Casing
Garages can be dusty, damp, and sometimes oily. Look for heaters made with durable metal casings, often steel. Plastic parts break easily under stress. A high-quality finish resists rust.
Heating Elements
For electric heaters, look for durable metal elements (like quartz or ceramic). These materials handle high heat well and often last longer than cheaper alternatives.
Factors That Improve or Reduce Quality
Quality is about more than just the materials. It involves how the heater performs over time.
Factors That Improve Quality:
Heaters with built-in thermostats give you precise temperature control. This saves energy. Forced-air heaters move heat around better than radiant heaters, warming the whole room faster. Look for good warranty support from the manufacturer.
Factors That Reduce Quality:
Cheaply made units often have weak wiring or thin metal shells. These heaters might fail quickly. Heaters that are very noisy also reduce the user experience. Always check reviews about noise levels.
User Experience and Use Cases
How you plan to use your garage dictates the best heater type.
Workshop Use (Staying Warm While Working)
If you need consistent, targeted heat while you are standing or sitting at a bench, radiant heaters work well. They heat objects directly, warming you up fast. These are often propane or infrared electric models.
General Shop Heating (Keeping the Whole Space Tolerable)
If you need to keep the entire space above freezing or just slightly warm between uses, forced-air heaters are better. They circulate warm air throughout the garage. Natural gas or large electric models often fill this role.
Infrequent Use (Occasional Tasks)
For quick trips to grab tools, a small, portable electric heater might be enough. They heat up fast and you can store them easily.
Garage Heater Buying Guide FAQ
Q: What is the biggest difference between radiant and forced-air heaters?
A: Radiant heaters act like the sun; they heat objects and people directly in front of them. Forced-air heaters blow warm air around to heat the entire room, like a furnace.
Q: Do I need special wiring for a powerful electric garage heater?
A: Yes, often you do. High-BTU electric heaters need a 240-volt circuit, similar to a large clothes dryer. You might need an electrician to install the proper outlet or wiring.
Q: Are propane heaters safe to use indoors in a garage?
A: They can be safe, but you must use models specifically designed for indoor/garage use. These models MUST have an Oxygen Depletion Sensor (ODS). Always ensure you have ventilation, even with ODS models.
Q: How do I calculate the correct BTU size for my garage?
A: A simple rule is to aim for about 10 BTUs per square foot of floor space for a well-insulated garage. If your garage has high ceilings or poor insulation, you need to increase that amount significantly.
Q: What is the cheapest heater to run?
A: This depends on local energy prices. Generally, natural gas is often the cheapest fuel source if you have a line. Electric heaters are cheapest if you only need a small amount of heat for short times.
Q: Can I use a small “salamander” construction heater in my garage?
A: Salamander heaters (often kerosene-fired) produce intense heat but require constant venting because they use up a lot of oxygen and produce exhaust fumes. They are usually not the best choice for a standard, semi-enclosed garage unless you vent them directly outside.
Q: What does “BTU output” mean on the box?
A: The BTU output tells you how much heat the heater makes. Higher BTU means more heat. Always match the output to the size of your garage.
Q: How much noise should I expect from a good garage heater?
A: Electric fan heaters are usually quieter than forced-air gas heaters, which have a noticeable blower sound. Radiant heaters are often nearly silent because they don’t use fans.
Q: Can I mount a heater on the ceiling, or must it sit on the floor?
A: Many powerful overhead units are designed for ceiling mounting. This saves floor space and distributes heat downward. Always check the manufacturer’s instructions for safe mounting height and clearances.
Q: How important is a thermostat on a garage heater?
A: A thermostat is very important for comfort and cost savings. It lets the heater turn on and off automatically to maintain your set temperature, preventing overheating and wasting fuel or electricity.
