In order to understand the answer to this question, you need to first know the difference between propane and natural gas. While natural gas occurs naturally, propane is a byproduct that occurs when natural gas is cleaned. Other byproducts include hydrocarbons, butane, ethane, and pentane.
To determine which of the two are best, there are several things to consider:
- Energy efficiency
- Risk factors
You’ll also want to consider what you’ll do with that propane tank in the backyard if you convert to natural gas. However, the cost of gas is significantly less than the cost of propane, so it shouldn’t take long to recoup your money. As you consider your furnace choices, do your research. Visit the websites of gas companies. Talk to professionals in your area who have experience working with both of these options.
