Faq about Propane and Natural Gas Heater:

Natural gas is generally more energy-efficient due to its lower cost and higher energy content, making it a preferred choice for many homeowners.

Yes, many natural gas heaters can be converted to propane with a conversion kit. Consult a professional for proper installation and safety compliance.
