Best Propane Heaters for Garage Buying Guide


Firstly, think about the space you’re trying to heat. If it’s a smaller closed in space, electric heaters are a great choice for safety reasons and they’re cheaper to buy. A gas heater is a better option for larger rooms because they hate the room quickly and cost effectively. So spending a bit more on buying one can reduce your longterm heating costs.

Type of Heater

Then there’s the type of heater. Let’s look at electric heaters first.

Radiant heaters with a ceramic or quartz element instantly heat up the person sitting in front of it instead of the whole room. They are cheap to buy, but the element gets hot. So best to keep them away from little ones and pets.

Convection heaters have an electric heating element that heats the air and most have a fan that circulates the warm air to heat the room faster. Hot air rises so convection heaters work really well in rooms with normal height ceilings.

A panel heater is a thin flat convection heater that you can move from room to room because it’s quite light or you can wall-mounted instead to save space. They are the more expensive option, but panel heaters heat rooms with standard ceiling heights quickly and evenly.

Oil column heaters take a little longer to heat rooms than fan-assisted heaters making them better to use for longer periods like in bedrooms overnight. Their surface doesn’t get as hot as radiant heaters so they they’re safer for families with little kiddies.

Fan heaters are the smallest most portable kind of electric heater. They heat a room faster than an oil heater, but some models may make some noise.

Okay now for gas heaters.

There are two types of these fluid and unfluid.

Unfluid gas heaters give you instant heat are very efficient and don’t need to be installed so perfect when you’re renting. You can move them around from room to room and take them with you when you move. It’s illegal to use unfluid gas heaters in some States because they do produce emissions so care needs to be taken in small or poorly ventilated rooms.

They’re also not the best option for people who suffer from asthma allergies or respiratory issues. Unfluid gas heaters are more expensive to buy but have cheaper running costs than electric heaters. So the initial upfront expense can save you in the long run.

Fluid gas heaters carry gas fumes outside via a pipe and are an efficient way to heat larger rooms. Remember, for safety reasons you need to have a fluid gas heater installed professionally which the good guys can organize for you to make life easier.

Additional features

Also consider different heat features. Would you like your remote control? Maybe you want the option of a thermostat so you can set a consistent room temperature or a programmable timer that allows you to save energy by having the heater turn on automatically when you need it like for a short time in the morning to warm up the room before you wake up.


It’s also really important to think about safety. Some heaters automatically switch themselves off if something’s wrong and some heaters have locks to enhance your home safety at all times.


And that’s it, the best five portable propane heaters for your garage. With these conventional home appliances available on the market today, you don’t have a reason to wait for summers before doing that desired project in your garage.
