Outdoor wood furnaces, commonly known as OWFs, are a popular choice for heating in Ontario due to their efficiency and reliance on renewable resources. In this article, we will provide a technical overview of outdoor wood furnaces in Ontario, focusing on their proper use, key features, and regulatory considerations.
Understanding Outdoor Wood Furnaces
Outdoor wood furnaces are standalone heating units designed to burn wood to produce heat. They are located outside your home, often in a shed or shelter, and they heat water, which is then circulated through insulated pipes into your building to provide heating through radiators, in-floor heating, or forced air systems. OWFs are favored for their efficiency, cost-effectiveness, and reduced environmental impact compared to traditional heating systems.
Key Features of Outdoor Wood Furnaces
High Heat Output: OWFs are known for their ability to generate substantial heat, making them ideal for heating homes, garages, workshops, and other structures.
Large Firebox: They feature spacious fireboxes that can accommodate sizable logs, reducing the frequency of refueling.
EPA Certification: Many OWFs are EPA-certified, indicating that they meet stringent emissions standards, making them eco-friendly heating options.
Secondary Combustion: Some models incorporate secondary combustion technology, which increases efficiency by burning unburned gases and particulate matter.
Remote Operation: Many OWFs come with remote control options for convenient operation from indoors.
Proper Use and Considerations
When using an outdoor wood furnace in Ontario, there are several important considerations:
Clearance Requirements: Ensure the OWF has adequate clearances from structures, property lines, and combustible materials as per Ontario regulations and manufacturer guidelines.
Chimney and Flue Installation: Proper chimney design and installation are essential for safe venting. Consult a professional to ensure compliance with local codes.
Fuel Quality: Only use well-seasoned wood with a moisture content of around 20% or less. Wet or green wood can reduce efficiency and lead to creosote buildup.
Maintenance: Regular maintenance, including cleaning the furnace and inspecting gaskets, seals, and chimney, is crucial for safe and efficient operation.
Regulatory Considerations in Ontario
It’s important to be aware of Ontario’s regulations governing the use of outdoor wood furnaces:
Ontario’s Ministry of Environment, Conservation, and Parks (MECP) has specific regulations on emissions and the installation of OWFs. Make sure your OWF complies with these regulations.
Some municipalities may have additional bylaws related to the installation and operation of OWFs. Always check local regulations before installing one.
OWFs must be installed a minimum distance from property lines and neighboring dwellings to reduce smoke and emissions impacts on neighbors.
Safety First
Safety is paramount when operating an outdoor wood furnace. To ensure safety:
Install and regularly maintain carbon monoxide detectors in your home.
Have fire extinguishing equipment accessible for emergencies.
Always adhere to local regulations and building codes for wood-burning appliances.
In conclusion, outdoor wood furnaces are a practical heating solution for many in Ontario. Understanding their technical details, proper use, regulatory considerations, and safety requirements is crucial for both technical and non-technical users. By following these guidelines, you can enjoy the benefits of efficient and eco-friendly heating while complying with Ontario’s regulations and ensuring the safety of your home and community.
