What Should you Look for in a Garage Heater?

Garage Space

When looking for a garage heater, the first thing you need to consider is the space you have. If you value floor space, you may want to consider a mounted garage heater. Most often, these are attached to the ceiling but there are  others that mount on the wall. Alternatively, if you have the floor space, an unmounted or portable garage heater enables you to position it to your preferred place.

Type of Heater

There are three main types of heaters that heat the space in different ways.

Forced-air heaters cycle blasts off hot air into the space and can be powered by either gas or electricity.The natural gas-powered versions tend to cost more and often need professional installation. Radiant heaters supply a steady warmth to the garage by using reflective panels that direct infrared heat. The most affordable variation of garage heater is the one that   uses an enclosed heating element or flame to allow the air to rise without a fan.

Fuel Consumption

Depending on your energy supply, you will need to consider the fuel used in your heater. Most are powered by natural gas, electricity, or propane, yet some use diesel or kerosene. Equally, the size and capacity of your heater will be dependent on the size of the garage you are trying to warm. Either look for the BTU (British Thermal Units) or for the directions that indicate the size  space each heater can cope with.

How Much Power Do I Need?

In order to understand the power needed to heat your garage space, you first must  understand a few key terms.

When referring to electric heaters, the wattage will give you an indication of how much space it can heat. The general rule of thumb is that you need 10 watts per square  feet of space. Heaters range in wattage, but you’ll find that newer models come with up to 5600 watts of power.

For other types of heaters, look for the BTU. This scale measures each BTU as how much energy it takes to heat one pound of water. In general, 1 watt is equivalent to 3.41 BTU, meaning you need at least 34.1 BTU to heat a square  feet.

It is important to also consider the temperature and insulation present in your environment. Very cold environments will need far more power to heat.

Garage Heater Fuel Types

The three most common fuel types used in garage heaters are gas, electricity and propane. Natural gas heaters are economical but you will need gas  tubes installed in your home. However, gas heaters are often a little more expensive upfront and sometimes need to be installed by a professional. The problem with natural gas heaters is that you will need to install ventilation to prevent poisoning from any toxic carbon monoxide that may be left behind.

Electric heaters usually direct infrared heat. They often come complete with an automatic shut-off when  a certain temperature is reached. Although these are not the greatest heaters for large spaces, electric heaters work well in small to medium spaces and provide a direct heating source.

Propane heaters are very efficient and economical heaters that warm a space quickly. They are great for warming large spaces and propane tanks are generally readily available. You need to be careful with them, though, as they can become dangerous if enclosed. Equally imperative is to  ensure you turn the gas tank off after each use , to prevent potentially lethal gas leaks.

Electric vs Gas Garage Heaters

In general, gas garage heaters are more efficient than those powered by electricity. Gas heaters  use less energy to make the temperature rise as much , meaning that they are more economical. Moreover, gas heaters have  greater capacity, that is why they heat much larger spaces more consistently and more quickly. 

Despite this, there are some financial implications you need to consider. For a natural gas-powered heater, you need to have gas  tubes installed in your house. If you need this installation, it will cost you money. This could make gas-powered heaters a less efficient choice for you. Equally, gas-powered heaters tend to cost more and often need professional installation, which again raises the costs.

Electric garage heaters are generally far cheaper to purchase and do not need any professional installation. Despite this, running these types of garage heaters  is far more expensive . On average, running an electric-powered heater costs 20% more than running a gas-powered heater.

Furthermore, heaters that run on electricity tend not to be able to heat  large spaces as consistently or quickly as gas. They are great for direct heat and for warming a small space, but in terms of heating large spaces, they are definitely far more inefficient than gas.
