Propane vs Natural Gas Furnace the Definitive Comparison

One of the fundamental choices when selecting a new forced-air gas furnace is the type of fuel it will use: Propane vs. natural Gas Furnace. The good news is that most modern furnaces offer the flexibility to run on either propane or natural gas. You can opt for a propane conversion kit at the time of furnace purchase if you need to fuel the unit with propane.

Propane or Natural Gas Furnace Fuel Source Basics

Propane is a fuel stored in liquid form, either in an above-ground or below-ground tank at your property. A truck usually comes to your home at set intervals to refill your propane tank, and you'll receive a separate bill for this service, distinct from your regular utility bills.

On the other hand, Natural Gas Furnace options tap directly into an underground piping network supplied by your municipality. Your monthly bill for natural gas usage is often integrated into your overall utility statement. Unlike propane, natural gas is delivered continuously, functioning similarly to how your water supply works: automatically and metered for billing.

Availability and Constraints

You often don't have the luxury of choice between propane or natural gas furnace systems because your options depend on the infrastructure in your area. If your municipality has an underground natural gas piping network, you're more or less locked into using natural gas. If not, propane becomes your sole gas alternative.

Cost Comparison: Which is More Economical?

Almost universally across the United States, natural gas is cheaper than propane. Not only is the fuel itself less expensive, but the delivery and storage of propane also entail added labor and costs. As a result, natural gas is generally the preferred option where available.

Exploring Alternatives: Heat Pumps

If the idea of using gas appliances doesn't resonate with you, consider an all-electric heat pump. Heat pumps are a viable alternative in many climates and eliminate the need for a gas connection altogether.

Whether you're looking at a Propane or Natural Gas Furnace, each option has its pros and cons. Propane offers flexibility in terms of storage but comes with a separate bill and usually a higher overall cost of a replacement furnace.

Natural gas furnaces, in contrast, are generally less expensive and offer the convenience of continuous supply but are limited by municipal infrastructure. Your decision will hinge on availability, cost considerations, and your comfort level with gas appliances.

When it comes to choosing between a propane or natural gas furnace, the key factors to consider include the availability of gas infrastructure in your area, ongoing costs,furnace sizing and your personal preferences concerning energy sources. If you're restricted by municipal infrastructure, your choice may already be made for you.

However, natural gas is usually more economical in the long run if you have the option. If you're wary of gas appliances in general, heat pumps provide an alternative that doesn't require a gas connection. Taking these factors into account can help you make an educated decision on the best fuel source for your home's heating needs.
