Fireplace or Furnace: Which One Is More Cost-Effective?


Share This Post

The primary objective of the heating, ventilation, and air conditioning (HVAC) system is to maintain indoor thermal comfort. In Canada, where winters can be brutal, people rely on various heating systems to keep their homes warm. Furnaces and fireplaces are popular options, but do you know which is more efficient? We will compare the efficiency of a fireplace and furnace to help you make an informed decision.

Difference between a Fireplace and a Furnace

Before discussing the efficiency of the fireplace and furnace, it is essential to understand what they are and how they work. A fireplace is a traditional heating system that burns wood or gas to create heat. It is often used for aesthetic purposes, as it adds an element of coziness and ambiance to a room. Meanwhile, a furnace is a forced-air heating system that uses electricity or gas to heat the air, which is then circulated through ducts to warm up the entire house.

Efficiency of Fireplaces

A fireplace’s efficiency depends on several factors, such as the type of wood or gas used, its design, and the room’s insulation. Generally, a wood-burning fireplace has an efficiency rating of 10-30%, which means that only 10-30% of the heat generated by the fire is used to warm up the room. The rest of the heat is lost through the chimney or flue.

Gas fireplaces are more efficient than wood-burning ones, with an efficiency rating of 70-99%. This is because gas burns cleanly and produces less waste than wood. Moreover, gas fireplaces can be equipped with blowers or fans to distribute heat more evenly throughout the room.

However, even with a high-efficiency gas fireplace, some drawbacks remain. For instance, gas fireplaces require a gas line installation, which can be expensive. Additionally, its cost can be higher than wood, making it more expensive to operate in the long run. Furthermore, a fireplace only heats the room it is in, which means that other parts of the house may remain cold.

Efficiency of Furnace

Compared to a fireplace, a furnace is a more efficient heating system. A high-efficiency gas furnace has an efficiency rating of 90-98%, which means up to 98% of the heat generated is used to warm up the entire house. Electric furnaces are also efficient, with a rating of 95-100%. 

Additionally, a furnace can be equipped with a programmable thermostat, allowing you to control the house’s temperature and save energy. You can also install a zoning system, which divides the house into different zones and allows you to control the temperature of each zone independently.

However, there are also some disadvantages to using a furnace. For instance, the initial cost of installation can be high, especially if you need to install ductwork. Additionally, it requires regular furnace maintenance, such as filter replacements and duct cleaning, to maintain its efficiency. Moreover, if it breaks down, it can be costly to repair or replace.


The efficiency of a heating system depends on various factors, such as the type of fuel used, the system’s design, and the house’s insulation. Ultimately, the choice between a fireplace and a furnace depends on your personal preferences, budget, and heating needs. If you want an efficient heating system that can warm up the entire house, a furnace is the way to go. However, if you are looking for a heating system that adds ambiance to a room, a gas fireplace may be the better option.
