Benefits of natural gas iron boiler

Capable of producing hot water at low or high pressure (up to a maximum of 620kPa), the cast iron boiler maintains water temperature for a long time (120 °C or 248 °F). The natural gas cast iron boiler achieves desired water temperature more quickly and maintains it longer than a steel boiler, thanks to its heaviness and thermal inertia

Reduce your energy costs

Cheaper than fuel-oil - Lower your energy bill by installing a natural gas cast iron boiler. Not only is natural gas more powerful than fuel-oil, it also costs less.

Consume less, spend less - With energy efficiency as high as 95%, a condensing boiler can generate substantial savings while improving performance! It’s the ideal solution when energy efficiency is a must, as in LEEDS projects, for example.

Choose the reliability of Énergir's network

By opting for natural gas, you are choosing Énergir’s reliable and secure distribution network! One of the most modern in North America, it meets the Canadian gas industry’s strictest standards and is monitored day and night, 365 days a year.

1. The rebates are applicable to businesses located on the Énergir gas network and equipped with central heating appliances, provided that they do not have a heat pump or dual-energy heating system. The amount of financial assistance is based on expected natural gas consumption, the type of appliance to be installed and the total amount of the investment. The 15% total corresponds to a potential customer who installs a natural gas warm-air furnace with a capacity of 10,000 m3. The rebates are subject to credit approval and eligibility for the natural gas Consumption Rebate Program and the Energy Efficiency Program. The terms and conditions of the program and the amounts of financial assistance are subject to change without notice. A five-year natural gas supply contract is required. Other conditions may apply. The financial assistance will only be paid once the natural gas appliance(s) is(are) installed. The eligibility criteria are listed in the Consumption Rebate Program guide approved by the Régie de l’énergie, a copy of which may be obtained on request.

2. The rebates are applicable to businesses located on the Énergir gas network and equipped with oil-fired central heating appliances, provided that they do not have a heat pump or dual-energy heating system and that the expected new natural gas appliance consumption is at least of 3,600m3 of natural gas. Other conditions may apply. The terms and conditions of the program and the amounts of financial assistance are subject to change without notice. To benefit from this grant, you must sign a contract with Énergir or an Énergir Natural Gas Certified Partner first.

1-2: The cost to switch to natural gas includes a basic connection charge of $300. An additional cost may apply if an extension to the natural gas network is needed, plus an additional contribution based on the expected consumption of natural gas. 

3. According to the prices in effect from July 1, 2021 to August 31, 2022. Based on Énergir rates and those of Hydro-Québec approved by the Régie de l’énergie; takes into account base electric consumption and rack price of oil with 2% sulfur including, in particular, transport, distribution and CATS.
