Are you a resident of Montreal and looking for a replacement for your old oil heating system? Don't worry, as per the law, its installation is now prohibited. Luckily, Plomberie Chauffage Normand offers bi-energy solutions that use natural gas and electricity for an eco-friendly and efficient heating experience. However, when it comes to choosing between hot air and hot water for electricity, it can be confusing to know which option to choose. In this blog, we will provide you with a comparison of both systems and help you make an informed decision that best fits your needs.


Comparison hot water and forced-air heating systems

Hot Water Heating

A hot water heating system utilizes a boiler to heat water. This heated water then circulates through a network of pipes installed within your home. Radiators or underfloor heating systems are connected to these pipes. The warmth from the hot water is transferred to these components, which then radiate it into the room through thermal radiation.


  • Advantages: It provides a gentle and uniform heat distribution, operates quietly, minimizes dust circulation, ideal for individuals with allergies and asthma.

  • Disadvantages: The installation is typically more complex and costly compared to forced air systems, may take longer to heat up a cold room.

Forced Air Heating

A forced air heating system employs a furnace to heat air. A fan then circulates the warmed air through ducts positioned throughout the house. Vents in each room allow the heated air to exit the ducts, warming the space through convection.


  • Advantages: It is generally less expensive to install than hot water systems, rapidly heats up cold rooms.

  • Disadvantages: It provides drier and less uniform heat, may generate noise due to the fan, and increases dust and allergen circulation, filters need to be changed regularly to be suitable for individuals with allergies.



Factors to Consider for Your Choice

  • Your budget: Installing a hot water system is generally more expensive than a forced air system.

  • Your comfort: If you're looking for gentle and uniform heat, hot water is the best option. If you need to quickly heat cold rooms, forced air is more efficient.

  • Your health: If you suffer from allergies or asthma, hot water is preferable as it stirs up less dust.

  • Your lifestyle: If you're often away from home, forced air may be a better option as it can quickly heat rooms when you return.


The choice between a hot water heating system and a forced air system depends on your needs and priorities. Feel free to contact Plomberie Chauffage Normand for a free evaluation of your home and personalized recommendations.
