How We Rated The Heaters

In terms of our experience of using various heaters, we have a relatively large garage that features a two post lift and space for up to five cars that needs heating up. Therefore, during the colder winter months (November through to April), we frequently use our garage heaters to maintain a comfortable heat within the garage.

As shown in the image, we own a powerful space heater that’s great for heating up the entire garage. However, we also own multiple electric heaters that are perfect for quickly heating up smaller areas where we are working.

Therefore, along with our experience, we also based our recommendations upon hours of research and multiple factors. Some of the factors that we took into consideration included the type, heat output, ease of operation, build quality, adjustability, power modes, portability, warranty and value for money.
