Electric heaters like this can have limitations in very large or poorly insulated spaces, where fuel-based heaters might generate more heat quickly.

However, there are some important considerations to keep in mind. First, while it includes a natural gas to propane conversion kit, the thermostat, hose, and regulator are not included in the purchase, which means additional costs may arise for complete installation.
