Commercial and industrial heating system optimization rebates

The following heating optimization measures can help improve the efficiency of existing gas boilers and related equipment:

• Economizer: A stack economizer helps to extract heat from flue gas for pre-heating of make-up water but also other fluids (e.g., domestic hot water).
• Economizer condensing: Functions like an economizer but provides additional efficiency by lowering the flue gas temperature and causing water vapor in the exhaust to condense, which releases latent heat and can be harnessed to further the energy efficiency of the system.
• Parallel positioning: Installation of parallel positioning system helps optimize combustion system efficiency. With parallel positioning, control valves for combustion air and natural gas fuel are positioned independently using individual actuators.
• Oxygen control (combustion oxygen trim): oxygen sensors that measures the oxygen concentration in the flue gas and enables air supply adjustment based on real time measurements, ensuring optimal oxygen levels.
• Total dissolved solids (TDS) control: Measurement of total substances (both organic and inorganic) in the water in the boiler to control the TDS levels as it can lead to scaling, corrosion, and reduced efficiency in boilers.
• Energy/heat recovery ventilators (HRV/ERV): This measure installs heat exchangers between two air streams without mixing the two air streams to recover heat/and moisture.
• Hydronic additives: Hydronic additives work by reducing water’s surface tension, which improves water’s ability to receive and deliver heat.
• Ozone laundry systems: An ozone laundry system generates ozone, a naturally occurring molecule which helps clean fabrics by chemically reacting with soils in cold water. Adding an ozone laundry system can reduce the amount of chemicals, detergents, and hot water needed to wash linens.
• Tune-ups: Tune-ups are maintenance procedures aimed at optimizing the efficiency and performance of a boiler. It will typically involve inspection, adjustment, testing and maintenance.

1. You must be a FortisBC gas customer under any rate class except Rate 1.
2. You must be a property owner or long-term leaseholder of an existing building or a builder/developer or property owner of a new construction project.
3. Your hot water or steam boilers must be used to meet your site or facility’s loads, e.g. process load, sanitization or space heating. Boilers installed to meet other operational needs (e.g. backup, standby or secondary boilers) are not eligible.
4. The hot water or steam boilers must use gas only.
5. Retrofit-only combination offer not available for new boiler systems or new construction.
6. Purchase date of products or services (as shown on the paid invoice) must be after December 19, 2024.
7. You must submit an application and supporting documentation no later than 365 days after the purchase date of the product(s) or service(s) (as shown on the paid invoice).
