Frequently Asked Questions

Will insulating my garage keep it cooler?

Insulating your garage will prevent heat from escaping from the garage during the winter and warm air from finding its way into space in the summer. Therefore, insulation will keep the garage warm in the winter and cool in the summer.

What is the most energy-efficient garage heater?

The efficiency of a heater is defined by its fuel-energy conversion rate. All our suggestions are very efficient. However, their efficiency levels differ slightly. The most efficient option is rated at 99.9% while others are not far from this figure. However, before you opt for the most efficient one, check to see if it meets your other requirements.

Is insulating the garage worth it?

Insulating your garage helps to maintain the existing temperature level of your garage. However, it may not give you the temperature level you need, especially during the extremely cold days simply because it doesn’t warm up space. Hence, having a garage heater is an absolute necessity. Using the combination of the 2 is even better and will reduce heating costs significantly.

How many watts of heat do I need?

The rule of the thumb is that a square-foot area needs 10 watts of heating power. Therefore, to know the right heating power, find the area of your garage in square-feet and multiple by 10 to find the ideal heating power for your space.

How do I calculate the BTUs I need for my garage?

To get the BTUs you need for your space, you need to get the area of your garage in square feet. Multiply the area to get the BTUs per hour you need for an hour. For instance, a 20 x 20 garage will need 8000 BTUs since its area is 400 square feet. However, it’s important to note that this value may differ depending on how your garage is insulated.
