Choosing a suitable commercial boiler for your business is an important decision that impacts both the comfort of your building and the efficiency of your operations. Whether upgrading your existing system or installing a new one, choosing the right boiler ensures reliable heating, energy savings, and optimal performance. 


Here are ten key factors to consider when choosing a suitable commercial boiler for your Toronto-based business.


  • Boiler size

    Ensure your boiler is the right size for your building. A boiler that’s too small won’t heat properly, while one that’s too large could waste energy. Professional sizing ensures you get the right fit.


  • Fuel type

    Boilers can run on natural gas, propane, oil, or electricity. In Toronto, natural gas is typically the most common and cost-effective option. If it’s unavailable, consider propane or oil, but they may cost more.


  • Energy efficiency

    Look for a high-efficiency model. Boilers with an AFUE rating of 90% or higher will save you money. Condensing boilers are highly efficient, as they recycle heat from exhaust gases.


  • Reliability

    Choose a boiler from a trusted brand known for reliability and durability. Reputable brands offer long-lasting systems that require less maintenance. Additionally, regular maintenance is essential to extend the life of your system and prevent costly repairs. Be sure to select a service provider, like Dupont Heating And Air Conditioning, that offers ongoing maintenance and 24/7 emergency services to keep your boiler in top condition.


  • Maintenance requirements

    Some boilers need more maintenance than others. Regular service helps prevent costly repairs. Opt for a boiler that is easy to maintain. Consider service packages for year-round care.


  • Installation space

    Make sure your boiler fits in the available space. Some units require more room or particular installation, such as specific venting or clearance. A professional installer can assess your space and ensure proper setup.


  • Climate suitability

    Consider Toronto’s climate. A boiler with a higher heating capacity may be needed for colder months. Talk to a professional about the best option for your specific weather conditions.


  • System noise

    Some boilers can be noisy, which might be a concern in quiet office spaces or retail environments. If noise could affect your business, look for a quieter model.


  • Warranty

    A strong warranty ensures you’re covered if anything goes wrong. Look for a boiler with comprehensive warranty terms on parts and labour, typically 5 to 10 years.


  • Budget and financing

    While energy-efficient boilers can cost more initially, they’ll save you money over time. Consider both the upfront cost and long-term savings. Dupont Heating And Air Conditioning provides financing options to help manage upfront costs.
