Advice On Buying 120v Garage Heaters

Why Is Voltage Important?

Unlike propane or natural gas heaters, electric garage heaters operate on electric power. Just like you would check the amount of BTUs per hour for a natural gas heater, for electric heaters you check watts and voltage. It equates to the power of the heater.

How Much Is 120 Volts?

An electric heater that uses a 120-volt power outlet is usually smaller in size. It is sufficient to heat smaller garages, shops, basements and similar rooms. If you have a large space that is harder to heat, you may want to choose a heater with a higher voltage – usually 240v.

Types Of Electric Heaters

When it comes to the way heaters distribute heat there are two main types – infrared and fan-forced. Infrared heaters use infrared technology to heat the surrounding object in the room that proceed to heat the air in the room. The latter uses a blower fan to heat the air, not objects or people.

Portable And Fixed

The difference between fixed and portable heaters is pretty self-explanatory. Fixed heaters are designed to stay in one place and can be mounted to a wall or ceiling, while portable heaters can be moved around where you want. What you choose entirely depends on your heating requirements and preferences.

Features To Look For

There are certain features that make it easier to choose the best 120v electric garage heater. Size and amount of power are a priority, but other features like a built-in thermostat, remote control and safety features like overheat protection can definitely enhance your heating experience.
