The Different Types of Furnaces You Should Know About

Furnaces come in a variety of shapes and sizes, each with its own advantages and disadvantages. It’s important to understand the different types of furnaces before making a purchase, as the wrong type can be costly and inefficient.

How Does a Furnace Work?

A furnace is a device that uses a heat source to raise the temperature of a space. The heat source can be anything from a simple flame to a more complex system like a boiler. The heat is then transferred to the space through a system of pipes or ducts.

Single Phase Versus 2 Stage Furnaces

A single-phase furnace only has two settings: on and off. This type of furnace is typically found in older homes and is less energy efficient than a two-stage furnace. 

A two-stage furnace has two settings: low and high. This type of furnace is more energy efficient, as it only runs on high when it’s extremely cold outside.

Standard Furnaces Versus Variable Speed Models

A standard furnace has a blower motor that runs at a constant speed, regardless of the outside temperature. A variable-speed furnace has a blower motor that adjusts its speed based on the outside temperature. Variable speed furnaces are more energy efficient than standard furnaces, as they use less energy when the outside temperature is milder.

Gas Furnaces Versus Electric Furnaces

Gas furnaces are more energy efficient than electric furnaces, as they use less energy to generate heat. Electric furnaces are less expensive than gas furnaces, but they will cost you more in the long run. Gas furnaces typically require less maintenance than electric furnaces, as they do not have any moving parts.

Furnace Efficiency

Furnaces are rated by their efficiency, which is measured in AFUE (Annual Fuel Utilization Efficiency). The higher the AFUE rating, the more efficient the furnace. A furnace with a high AFUE rating will cost more to purchase but will save you money in the long run.

Furnace Sizing

Furnaces are sized by their BTU (British Thermal Unit) output. The BTU output of a furnace is the amount of heat it can generate in an hour. The size of your furnace should be based on the size of your home, as a furnace that is too small will not be able to heat your home, and a furnace that is too large will use more energy than necessary.

The Bottomline

In conclusion, there are many different types of furnaces on the market, and homeowners need to understand the different types to make the most informed decision when purchasing a furnace. While the furnace is an important part of the home, it is also important to consider the cost of a new furnace, installation, and annual maintenance.
