Best Gas Furnace Buying Guide

Before choosing the best gas furnace you should consider the following options:

Fuel Source

Before you buy a gas furnace, you first need to determine the fuel source you want. There are three types of gas furnaces available in the market and they are:

Direct Vent

Direct vent gas heaters are also sometimes called power vent heaters and are usually smaller in size. They are meant to be installed in places where there is enough ventilation. Direct vent heaters are suitable for installation in attics, crawl spaces and gable ends. They are easy to install and require less maintenance. They are not suitable for installation in closed spaces, such as a basement.

Indirect Vent

Indirect vent gas heaters are popularly known as heat exchangers. They are larger in size and use a heat exchanger to distribute heat throughout the house. The heat exchanger is usually installed in the crawl space or basement and the blower is installed in the attic. Indirect vent heaters are suitable for installation in closed spaces.

Power Combination

These are a combination of direct and indirect vent heaters. They are suitable for installation in almost any location.

Gas Fuel vs. Electric Fuel

There are many advantages of using a gas furnace instead of an electric furnace. Here are a few:

  • Gas heaters generally have higher efficiency and lower operating costs.
  • Gas heaters are usually smaller in size and have a streamlined look.
  • Gas heaters are easier to install and require less maintenance.
  • However, there are some disadvantages of using a gas furnace instead of an electric furnace:
  • Gas heaters are noisy compared to electric heaters.
  • Gas heaters have a short lifespan compared to electric heaters.
  • Gas heaters are difficult to install and require proper ventilation.
  • The main thing to keep in mind here is whether you have proper ventilation where you want to install the gas heater. If you don’t have proper ventilation, then you should not choose a direct vent gas heater.

Size

A gas furnace should be sized appropriately to save on energy costs and perform efficiently. Here are a few things you should keep in mind when choosing the size of your gas heater:

  • A larger gas heater will obviously have higher energy costs.
  • Gas heaters are generally smaller in size compared to electric heaters.
  • Heat output is measured in BTU (British Thermal Unit) and is usually measured in tons. One ton is equal to 12000 BTU.
  • A smaller gas heater will obviously have lower energy costs.
  • A smaller gas heater will take longer to heat up the house.
  • Choosing a gas heater that is undersized will result in higher energy costs and the gas heater will not perform efficiently.

On the other hand, choosing a gas heater that is oversized will result in reduced heating efficiency. The main thing to keep in mind here is whether you have proper ventilation where you want to install the gas heater. If you don’t have proper ventilation, then you should not choose a direct vent gas heater.

Maintenance

Maintenance is an important aspect to keep in mind when choosing a gas furnace. Here are a few factors to consider:

  • Gas heaters generally require less maintenance compared to electric heaters.
  • Gas heaters are easier to maintain with simple and affordable components.
  • Gas heaters have fewer moving parts and are therefore easier to maintain.
  • Indirect vent gas heaters require the least amount of maintenance compared
