Best 240v Garage Heater Buying Guide

From the reviews, you can tell that the best electric garage heater 240v come in a wide range of styles and design options. The following considerations should help you pick the right one for your application.

Types of Electric Garage Heaters – Which can be the Best 240v Electric Garage Heater?

There are two broad ways to categorize electric garage heaters – by the heating method and by portability. By the method of heating, you can choose either fan-forced (convective) or radiant heaters. When it comes to portability, meanwhile, there are two options; fixed and portable.

Let’s find out what you get with each option.

Fan-Forced vs. Radiant Heaters

Fan-Forced heaters

Fan-forced heaters are some of the most common, even if not in the garage. The way they work is simple. An electric current is passed through a heating element inside the heater. As the electric element heats up, it dissipates some of the heat to the air passing through the heater. The hot air is then pushed out of the heater and into the rest of the room.

The reason they are called forced-air is that they often use a fan or blower system to aid the distribution of warm air. The inbuilt fan blows the warm air faster and more evenly throughout the intended space. The action of the fan, combined with natural convection, also helps draw cold air into the heater.


  • Lower initial costs: Very often, fan-forced heaters cost less than twice the price of similarly rated radiant heaters.
  • Even heating: Fan-forced heaters are also better at heating a space evenly. Thanks to the fan, heat is pushed to every corner of the room.


  • Higher operation costs: Over a year, it costs more to run a fan-forced heater than a radiant heater. Why? Because fan-forced heaters are less efficient.
  • Lots of noise: The blowing fan makes significant noise. Unless you’re willing to work through it, this noise could be a nuisance.

2. Radiant Heaters

Though fan-forced heaters are the more common type of heater in homes in general, in the garage, radiant heaters rule.

These heaters work slightly differently from convective heaters. Although they also involve the passing of electric current through an electric element to generate heat, the heating element and the heat distribution process are different.

First off, fan-forced (convective) heaters often use a metal heating element. Radiant heaters, however, mostly use quartz heating elements. Secondly, rather than pass the heat to the surrounding air, radiant heaters transmit heat in electromagnetic waves that only heat objects. The waves leave the surface of the heating element and are only absorbed by solid objects on their path, such as you.


  • Very efficient heating: Since the resulting heat is directed to objects such as people that need it most, this form of heating is very efficient. You don’t have to worry about warm air being blown out of the room.
  • Easy to work around: Radiant heating is less noisy, thus less distraction. Also, you don’t have to move furniture and other items around to make room for airflow.


  • Expensive: Very often, radiant heaters cost twice as much as comparable convective electric heaters.

Fixed vs. Portable

1. Fixed Heaters

Fixed electric garage heaters are permanently installed. They can be installed either on the wall or the ceiling just like some wood heaters for garage.


  • Safer: Since the units are permanently installed in a secure location, you don’t have to worry about tip-over and tripping over cables.
  • Easier maintenance: Once the heater is permanently installed, you also don’t have to worry about accidental spills and breakages. This reduces maintenance requirements and prolongs the appliance’s life.


  • Professional installation required: Installing a fixed garage heater requires the expertise of a professional. This could add to initial investment costs.

2. Portable Heaters

Portable garage heaters are often smaller and designed to be easily carried around. In most cases, they come with easy-grip handles for carrying.


  • Take it everywhere: Since you can carry the heater around with ease, you can use it in many other applications, even outside the garage.
  • Lower initial costs: Portable heaters are smaller in size and plug-in (rather than hardwired), thus require a lower initial investment.


  • Prone to accidents: Tip-over and tripping over cables are two common accidents when using portable heaters. Accidental touching of hot parts is another possible issue.

Factors to Consider When Buying the Best 240V Electric Garage Heater

There are several factors to consider when selecting a 240-volt electric garage heater. These include;

  • Power (watts)

Depending on the amperage (amps), a 240-volt heater can have a power (wattage) rating anywhere up to 10,000+. Home heating experts recommend 4,000 to 5,000 watts for medium-sized garages and 7,500 watts or more for 2-car garages or larger applications.

  • Features

Vital electric garage heater features include adjustable louvers for heat direction and a long power cord for convenient positioning. Also, look out for easy lift carry handles for effortless mobility and wheels where necessary.

  • Settings/Control

Settings and controls to prioritize include timer function, remote control, and a thermostat. Also, consider the type of thermostat. Is it programmable? Is it in-built? Digital control is another factor to consider.

  • Safety

Finally, it’s critical that you find a safe-to-use heater. A safe heater is certified or listed by a recognized testing laboratory such as the UL, CSA, CUL, or ETL. The heaters also feature safety technologies such as anti-tip-over protection, cool-to-touch housing, and overheating protection.
