Things to Consider Before Buying the Garage Heater
One crucial thing you will need in the garage during the winter season is a good electric garage heater. A garage heater should be a long-term investment, and thus you need to be serious when purchasing. Here are just some important considerations you should make to distinguish the best garage heater from the many heaters in the market.
1. Garage Size
The size of your garage is a vital factor to consider when buying an electric heater. Different heaters offer a different amount of power. A small heater with less power will work well for a small garage, but it will take a very long time for the same heater to heat a large garage.
When selecting a heater, the ground rule is that every 10 watts heat 1 square foot of the area. You also need to answer whether you want to heat the whole garage or just a part of it? Therefore, you should ensure that the heater you choose should have enough power or output to cater to the garage space.
An electric heater can be quite dangerous if not set up, installed, or used properly. The safety of the garage heater is important, especially in places where there are pets or children. Look for an electric garage heater with various accident-proof features. The heater should have an auto shut tip-over feature where it shuts itself off if it is knocked over.
The heater should have an overheating protection feature, which is important in days of prolonged use. With this feature, the heater will automatically shut off when it senses an excess rise in temperatures. This protects the heater from internal damage and the garage from external damage. If the heater you plan to buy is portable or wall-mounted, ensure it has cool-touch features. This will prevent people from passing around from getting injured or burnt.
3. Portable or Fixed
It is important to check if the heater you want to buy is portable or fixed. If you want a heater you can move around with, maybe from the table room to bedroom, to garage, you need a portable electric heater. If the heater is to be fixed in the garage, then check on the easiness for mounting and where it should be mounted. Some can only be mounted on the floor, wall, ceiling, while some can be mounted anywhere.
When buying a portable electric heater, consider if it has handles and wheels. The heater should have a comfortable handle to carry it around before you get the right place to put it. Heaters with wheels are also easy to maneuver around, especially if it is large and bulky.
4. Adjustable Thermostat
A thermostat gives the user the freedom to set the garage’s cooling and heating temperatures to suit their needs and minimize the total energy cost. When looking for a thermostat option in an electric garage heater, consider the amount of energy you need in the area and unit type.
A heater with an inbuilt adjustable thermostat monitors the ambient room temperature and turns on when the room temperatures are low, and shuts off when the room temperatures are high. This will help you to choose your desired temperature for the garage.
This is a great feature in cold climates where you need 24-hour heating. The auto-off and auto-on features will keep the garage in the right temperatures without wasting too much unnecessary energy.
5. Adjustable Louvers
At times you might need more heat in a particular place in a garage than in others. Choosing a heater with adjustable louvers will enable you to direct more pressure to these areas. The adjustable lovers will help you direct the heat to your desired area in the garage. This feature makes your heater more practical and useful.

2. Fan Forced Heaters
These heaters are also known as forced air garage heaters. These types of heaters vary in price, fuel type, and size, but they all work the same. The heaters convert electric energy to heat and use the fan for cycling hot air blasts in the space. Fan forces heaters are portable and easy to install. Most of them, however, make noise due to the fan. They are suitable for workshops, basements, and garages.
3. Convection Heaters
These heaters rely on a heating element or an enclosed flame to warm the air in the unit. Convection heaters take air from one side, warm it and release the hot air from the other side. These heaters take some time to heat, but when they do, they warm up the entire place. Most conventional heaters are quiet during operation.
Garage heaters can also be classified based on where they get their power from like below:

1. Ceiling or Wall Mounted

The heaters are also away from any combustible materials since they are either mounted on the wall or ceiling. Most gas heaters are mounted because they need a ventilation system.
2. Floor Heaters
These are heaters that run from the garage floor. These heaters have to consume some space in the garage since they need a safe and stable place to stand. Always ensure that you have placed the floor heater away from any combustible materials. Floor heaters are easy to carry, portable, and need no installation.
