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

November 24, 2020

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

Garages don’t often have the ductwork needed for regular heating and cooling systems. While you can get ductwork, it’s not the most economical solution. The best approach to heat your garage is by having 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 find the ideal option for your needs.

What is a Mini-Split?

A mini-split is much like a heat pump because it shifts heat instead of generating it. This makes it an extremely energy-efficient heating and cooling system for areas that don’t have ductwork. These electric systems are typically installed on a wall and joined to the outdoor unit through a small hole in the wall.

Though a ductless mini-split costs more, most have earned ENERGY STAR® recognition for their energy efficiency. They’re also extremely quiet and provide zoned comfort, which offers precise control over your garage’s temperature.

Many mini-splits allow you to join several indoor units to one outdoor unit. If your garage is adjacent to your house, you may be able to have added indoor units in areas that are tricky to heat and cool.

What is a Garage Heater?

A garage heater is better than a space heater. This all-encompassing heating solution is installed on the ceiling or the higher corner of a wall. Depending on the model, these heaters can use electricity, gas or propane. They’re a good choice if you reside in a chilly climate and do a lot of grubby dirty work. Garage heaters are heavy-duty and created to withstand extra grime.

Garage heaters are the most economical solution. The typical expense is different because of fuel type, but they’re typically about half the cost of a mini-split.

Operating Costs

Garage heaters work similarly to a furnace, needing fuel to generate hot air. A mini-split air conditioner is nearer to a heat pump, which moves heat. This makes a mini-split more efficient to use. You’ll have reduced energy costs if you choose an ENERGY STAR® certified model. And you may be entitled to additional rebates because of that energy efficiency.

Fuel Source

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

Heating and Cooling

As its title indicates, a garage heater only provides delivering heat. A ductless mini-split offers both heating and cooling.

Precise Temperature Control

When you are seeking the most precise comfort control, a mini-split heat pump is the smartest option since it delivers zoned heating and cooling. That way, your garage will be the right temperature you want it to be.

Space Considerations

Because garage heaters are often mounted on the ceiling, they can eat up valuable overhead storage room. In comparison, low-profile mini-split systems are usually put higher up on a wall and don’t have to have a lot of real estate.
