Electric heaters

Electric heaters generally have lower initial installation costs because they simply require an appropriate electrical outlet, making them a straightforward option for those looking for an easy setup.

Although the operating cost of electric heaters can be higher, depending on local electricity prices, they are more efficient in their conversion of energy to heat. Electric heaters are considered safer than gas heaters as they do not produce carbon monoxide or other exhaust gases, eliminating the risk of gas leaks in enclosed spaces.

The environmental impact of electric heaters depends on the source of the electricity; if it comes from renewable sources, the impact is lower, but it’s higher if generated from fossil fuels. Electric heaters generally require less maintenance than gas heaters, as they have fewer moving parts and do not involve burning fuel, making them suitable for smaller spaces or for those who prioritize energy efficiency and safety.

Gas heaters

Gas heaters typically have lower operating costs, especially in areas where natural gas is more affordable than electricity. They are capable of heating a space more quickly and are considered more cost-effective over time for heating larger spaces.

However, gas heaters come with higher initial installation costs due to the necessity of a gas line and proper venting to ensure safety. If your garage isn’t already equipped with a gas line, the cost and complexity of adding one can be significant. These heaters produce combustion gases that must be vented outside, requiring careful installation and maintenance to prevent carbon monoxide poisoning.

It’s essential to have carbon monoxide detectors installed.

FAQ for gas and electric garage heaters buyers

What size heater do I need for my garage?

The size of the heater you need depends on several factors, including the size of your garage, the insulation quality, the desired temperature increase, and the climate you live in. As a general rule, you can estimate the required heating power by calculating 10 watts per square foot of floor area for electric heaters or using a BTU calculator for gas heaters.

For example, a 500-square-foot garage would require approximately a 5,000-watt electric heater or a heater capable of producing around 17,000 BTUs if opting for gas. It’s important to consider insulation and garage use to select a heater with the right capacity for your needs.

Are electric garage heaters more expensive to run than gas heaters?

Generally, electric heaters can be more expensive to run than gas heaters due to the higher cost of electricity compared to natural gas in many areas. However, the exact difference in running costs will depend on local utility prices and the efficiency of the heaters being compared.

Electric heaters are very efficient at converting energy to heat, with almost no loss, while gas heaters can heat larger spaces more quickly. If you’re concerned about operating costs, it’s crucial to compare the efficiency of specific models and consider your local utility rates to determine the most cost-effective option for your situation.

How safe are gas and electric garage heaters?

Both gas and electric garage heaters are designed with safety in mind, but each has its specific considerations. Electric heaters are generally considered safer because they don’t burn fuel, produce combustion gases, or risk leaking carbon monoxide. However, they should still be used with caution, especially regarding their placement to avoid fire risks from nearby combustible materials.

Gas heaters, while efficient and cost-effective, require careful installation, regular maintenance, and proper venting to prevent carbon monoxide poisoning and gas leaks. It’s essential to install carbon monoxide detectors in your garage if you’re using a gas heater. Always follow the manufacturer’s safety guidelines and consider professional installation to ensure safety and efficiency.
