How Do I Keep My Garage Hot?

A lot of people want to know how to keep their garage cool. And lots more people want to know how to heat their detached garage. These are almost the same, even if they are on different sides of the temperature spectrum. Cooling your garage involves air conditioners, dehumidifiers, fans, and insulation. Heating your garage involves floor heaters, combustion space heaters, radiant heating, and also insulation! Same-same, but different.

How to Heat a Detached Garage

Everyone deserves to be comfortable. If you own your home, chances are your detached garage is your safe space. Maybe you have projects on the go, maybe want to keep an old car heated, or maybe you just want all your boxes of old clothes to stay nice and warm.

There are tons of ways you can keep your garage heated. Because it is detached, it likely doesn’t share the same heating system as the rest of your house. You could install a fireplace, a wood burning stove, a ductless heating system, an additional level of insulation, in-Floor heating, a portable space heater, or even an infrared heater that you hang from the ceiling.

Naturally, the biggest difference of how you keep your garage hot in the winter and comfortable in the cool months comes down to price. For example, an extra level of insulation on your garage door is going to be extremely affordable. On the other hand, installing something complicated like a ductless heating system is going to cost you a ton of money.

Before you get too crazy and start buying up heaters, you should be aware of how each heating method can directly affect your comfort. For example, a forced air heater is great for hanging on the ceiling of an industrial warehouse, but in your garage it will have a tendency to blow things around and be annoying.

If you have your eye on a fireplace, you must know there is going to be a lot of work to install it. On the other side, if you want an electric fireplace, you have to think about the amount of money that will be sucked away in electricity bills. Everything has a pro and a con, and we are going to discuss them in serious length at the end of the article.

First, let’s take a look at the 10 best solutions you can buy right now for heating your garage.

You may need a professional to install this for you. Also, this is a 3-zone model, meaning you can hook up three wall mounts to the same outdoor unit. It’s nice to have spares.

Best Ways to Heat a Detached Garage: A Complete Guide

Believe it or not, when heating a detached garage, you have even more options than when keeping it cool. Keeping your garage cool involves an air conditioner and a fan. It is pretty simple. But if you want to stay warm in the winter, you have a whole pile of different options to choose from. I am going to detail all of them in this guide to give you a better idea of what you’re dealing with.

Naturally, it comes down to price and effort. How much effort are you willing to put in to keeping your garage warm? How much money are you willing to spend? The lazy among us should definitely opt for a space heater or even an infrared heater, as these are surely the easiest options.
The hardest options involve quite a bit of work.

If you want floor heating, you need to do some serious renovations. However, if you are into a non-vent heater, all you need is to hook up the natural gas supply. Then there is the air conditioning option, where you can install a wall-mounted heating system that works just like an air conditioner. In fact, most air conditioners work both as coolers and as heaters. How do you think the corner store stays warm in the winter?


Insulation is a classic method. If your garage is insulated properly, and if you don’t live in the frigid wasteland of Siberia, you can probably get away with not buying a heater. Because we’re talking about a detached garage, you can easily insulate the walls and the ceiling to keep the heat inside.

You can also seal the areas around the windows and the doors to keep any heat from escaping. The whole point of insulating your garage is to keep the warm air inside. The last thing you want is your valuable heat slipping sneakily through cracks around the window or around the door.
Portable Space Heater

This is the most common option. Anyone who lives in a cold place has experience with a space heater. These can be very small or very big, and they range wildly in price. However, they are agreeably cheap. A simple space heater can very quickly heat any room in your house, or in your garage. These units are portable, they are mostly safe, and they can be purchased anywhere.

Infrared Heater

You have probably seen infrared heaters outside of your local cafe or bar, looking like cheap mosquito killers. These are very intense ways of heating your garage. They do not push heat or blow air. These are tubes that heat up immensely to radiate heat throughout your entire garage.

However, these can be dangerous. Infrared heaters are the biggest potential fire hazard on the list. They are also notorious for heating everything in your garage except the air, kind of like a microwave. The only huge bonus is that they are very quick to install.


This option really depends on what you are doing in your detached garage. If you are storing cars or junk, you probably don’t want to install a wood burning stove. A fireplace would look ridiculous sitting next to your cars. However, if your garage is a workspace or a private space where you lounge and relax, you may want to consider a wood burning stove. A stove or a fireplace both look equally suave in any nicely decorated space.

The only issue with an actual stove that burns wood is that you may need a permit from your local municipality. You may also need to renew your home insurance if you are adding something like a stove. However, these are very easy to acquire from your local hardware store. However again, they are not easy to install. You obviously need some ventilation, and then you need a good supply of wood to burn.

Ductless Heating

Ductless heating is a fancy word for air conditioning. These units are just like air conditioners. You can mount them to the wall and then fix them to the main unit outside. These are quiet, easy to control, and almost all of them have cooling features. The most common form of ductless heating is with a multi-split system, which is generally energy efficient and much easier to install than floor heating or an HVAC system. If you have some basic heating knowledge, you can likely do this yourself.

In-Floor Heating

This is definitely the most complicated and expensive system of heat for your garage. Believe it or not, in-floor heating is getting more and more popular in new houses. You can get this installed in any room, in your hallway and even in your kitchen. The whole idea is to warm your floors from underneath by using electricity or water.

In houses it can be done with water pipes running beneath the floor and generating heat. But in your garage, you will want to use electric underfloor heating, which involves special wiring beneath the floorboards that not only keep the room warm, but your feet too.

This is probably the best method for anyone who spends a lot of time working on vehicles in the cold. When you lay down on the floor, it is going to be warm. If you find yourself under a lot of cars, it is a serious luxury to have your back heated while lying on the floor.

Natural Gas Heating

There are a few types of natural gas heating systems. A propane heater is very popular – they are also portable and easy to use – but then you need to have a supply of propane. My personal favorite is a natural gas heater that runs on no electricity and only uses the natural gas lines from your house. You do need a professional to install the lines properly into a natural gas heater, but this is the best ways to heat a room. You will be much happier in your garage with natural gas heat.
