Mini Splits vs. Garage Heaters: What Should I Install in My Garage?

November 24, 2020

Your garage can be more than just a space to put your vehicles in Port St. Lucie. It can be a workshop, give extra storage and more. But when you’re out there more often, it needs to be a comfy temperature.

Garages don’t usually have the ductwork required for common heating and cooling systems. While you can add ductwork, it’s not the most cost-effective option. The best approach to heat your garage is by using a ductless comfort system, like a mini-split system or a garage heater.

Let’s go through the difference between the two to help you discover the best solution for your needs.

What is a Mini-Split?

A mini-split is close to a heat pump as it shifts heat rather than generating it. This makes it a very energy-efficient heating and cooling system for spaces that don’t have ductwork. These electric systems are often placed on a wall and joined to the outdoor unit through a tiny hole in the wall.

Even though a ductless mini-split is higher priced, many have received ENERGY STAR® recognition for their energy efficiency. They’re also extremely quiet and offer zoned comfort, which provides exact control over your garage’s temp.

The majority of mini-splits allow you to join several indoor units to an individual outdoor unit. If your garage is part of your house, you could be able to have added indoor units in areas that are tricky to heat and cool.

What is a Garage Heater?

A garage heater isn’t a space heater. This all-in-one heating solution is mounted on the ceiling or the higher corner of a wall. Depending on the model, these heaters can run on electricity, gas or propane. They’re a good choice if you reside in a cold climate and perform a lot of grubby dirty work. Garage heaters are heavy-duty and designed to keep working through additional grime.

Garage heaters are the most economical option. The typical cost differs based on fuel type, but they’re typically about half the cost of a mini-split.

Operating Costs

Garage heaters are similar to a furnace, using fuel to create hot air. A mini-split air conditioner is nearer to a heat pump, which transfers heat. This makes a mini-split more efficient to use. You’ll enjoy even lower utility expenses if you get an ENERGY STAR® certified model. And you might be eligible for extra rebates as a result of that energy efficiency.

Fuel Source

Garage heaters have the broadest options for fuel kinds—electricity, gas or propane. Mini-splits are electric.

Heating and Cooling

As its designation says, a garage heater only provides providing heat. A ductless mini-split offers both heating and cooling.

Precise Temperature Control

When you are looking for the most accurate temp control, a mini-split heat pump is the best answer as it provides zoned heating and cooling. That way, your garage will be the right temperature you want it to be.

Space Considerations

As garage heaters are usually installed on the ceiling, they can eat up valued overhead storage area. On the other hand, slim mini-split systems are typically placed higher up on a wall and don’t have to have a lot of space.
