In February 2019, FortisBC announced the launch of a new prescriptive rebate offer with the aim of encouraging the adoption of high-efficiency steam boiler technologies in BC’s industrial and commercial sectors. It joins a host of other rebate programs that contribute to FortisBC’s overall objective of improving natural gas efficiency across the province.
We’re thrilled to announce that Raven Supply as FortisBC’s Conservation & Energy Management Commercial Partner delivered its first instant point of sale rebate to a customer using the new steam boiler rebate offer. FortisBC offers several prescriptive rebates that can be used towards the purchase of a new steam boiler or upgrades to existing systems meeting certain eligibility criteria.
The Commercial Partnership agreement allows Raven to assess customer eligibility during the sales process and deduct the rebate value straight off of our customer’s invoice, so customers can benefit from the savings immediately with zero uncertainty and minimal paperwork. This makes it very easy and approachable for end-users to take advantage of the program.
This customer chose to purchase a Fulton VMP-49.5 HP high-pressure steam boiler to replace their existing Fulton ICS-60 HP. This vertical tubeless boiler packs 49.5 horsepower into a heating surface area of less than 10 square meters, so the customer is not required to register the boiler plant or employ any Power Engineers under BC laws. This fact alone represents a huge cost-saving for most organizations, making the VMP-49.5 a tremendously popular boiler for process plants in British Columbia.
Because the Fulton VMP comes standard with parallel positioning controls, the customer’s invoice was instantly reduced by $9,000. In addition to the rebate savings, these features will save the customer thousands more in fuel costs due to higher operating efficiencies and reduced cycling losses. Jermin Hsieh, Conservation & Energy Management Program Manager at FortisBC provided feedback that Raven Supply provided excellent customer service by educating the customer on energy-efficient options and tying in point of sale rebates.

To be eligible for these steam boiler rebates, you must be a FortisBC customer using natural gas as your only fuel during normal operation. This includes dual-fuel burners used for emergency backup. For a complete list of criteria, visit the FortisBC website or call Raven for more information.
FortisBC offers rebates for steam boilers for four key technologies that can either be factory fitted on a new steam boiler or retrofitted onto an existing steam boiler as an upgrade:
Parallel positioning (often referred to as “linkage-less” control) is a precise, repeatable method of controlling the flow of fuel and air through a modulating burner. The fuel control valve and air damper are each moved by their own dedicated stepper motor actuators, each of which is electronically controlled by an air-fuel ratio controller.
On the other hand, a “linkage” burner uses a single servo motor to modulate both the fuel valve and air damper which are mechanically connected together by a series of adjustable jackshafts and linkage arms. The difference is similar to how modern electronic fuel injection systems compare to carburetors in automotive engines.
When air and fuel flow are parallel position systems, so when these elements are accurately controlled, a well-designed burner can be precisely tuned to minimize leftover oxygen in the exhaust throughout the full turndown range. This leftover oxygen in the exhaust is referred to as “excess air” and is inversely proportional to combustion efficiency. That means that lower excess air means lower fuel consumption.
There are many factors that can affect the net fuel savings realized by switching to parallel positioning controls. A typical estimate would be 5%, although savings of 15% or more are quite possible in certain circumstances. Linkage-less platforms like the Weishaupt W-FM and Siemens LMV are generally known to be safer, more reliable, and require less maintenance over time than conventional burner controls.
Steam Boiler Rebate Value -$16,000 – $18,000
Oxygen trim is an additional control feature that works in conjunction with parallel positioning. A sensor installed in the flue stack provides the burner controller with continuous closed-loop feedback of the O2 concentration in the flue gas, allowing it to automatically make fine adjustments to the air/fuel actuators as needed for optimal combustion. This makes the burner adaptive to changes in air temperature, atmospheric pressure, or other factors that may affect combustion. Net annual fuel savings of 1-2% are typical when this technology is correctly applied.
Total Dissolved Solids Blowdown Control
Steam Boiler Rebate Value – $4,000
In addition to bottom blowdowns, a commercial or industrial steam boiler needs regular surface blowdowns to be performed in order to flush out excess treatment chemicals, debris, and other impurities that may naturally collect at the water surface during operation. In practice, we associate the concentration of impurities with electrical conductivity, which is relatively easy to measure with current technology. A total dissolved solids (TDS) automatic blowdown system monitors the water conductivity and automatically performs blowdowns only when required. This ensures minimal water is wasted while maintaining good water chemistry, which contributes to both energy efficiency and equipment longevity.
Steam Boiler Rebate Value- $10,000 – 25,000
A stack economizer is a heat exchanger that extracts additional energy from a boiler’s flue gas and transfers it another medium which could be boiler feedwater, domestic water, or a hydronic heating loop. Economizers are typically found on larger boilers, usually mounted on top of the flue collector outlet. They offer the most energy savings in systems that consume a reasonably high percentage of cold make-up water, or where there is another consistent and substantial demand for water heating, such as a large domestic or process hot water load. Although economizers may add some complexity and space requirements to the system, they can produce significant energy savings when used in the right application.
Burner/Burner Control Retrofit (existing steam boiler upgrade)
Steam Boiler Rebate Value- Up to $49,000
Upgrading your existing steam boiler by upgrading the burner is a great way to increase fuel efficiency, improve reliability, improve overall boiler performance, and reduce maintenance/downtime expenses. Depending on the total project cost, FortisBC will offer up to $49,000 as an incentive for adding parallel positioning and oxygen trim to your existing boiler. In many cases, a burner retrofit can be completed within a few days, with minimal impact on the rest of your operations. Contact us to find out if your boiler is a good candidate for an upgrade!

Raven Supply works with consultants and contractors from all across BC and the Yukon. Phone calls and emails are nice, but when we get the chance, we love to travel to meet these partners in person and get to know the city they call home, too.
So when Merinda Widmer and Linna Luu got the opportunity to take a short trip to Whitehorse in the Yukon Territories in June, they jumped at the chance.
Merinda and Linna, two of our engineers, were especially excited to check in on a few of our boiler projects in person, as well as find out more about this community that Raven Supply works in.
“We got to see the three Bryans we have at Whitehorse General Hospital,” says Linna. “We also dropped by Yukon College to see how our venting compared to the other stacks.”
Impressed (but not surprised) with how well these projects were holding up, next stop on the agenda was getting to know the people and places of Whitehorse.
“It was great getting to meet all the consultants, engineering firms and contractors we work with on a regular basis,” explains Merinda. “It’s fantastic to finally put faces to these names we know so well!”
“Everyone was very welcoming and took time out of their schedules to speak with us. The sense of community is very apparent!” adds Linna.
With a population of around 25,000, a strong sense of community in a smaller city like Whitehorse is to be expected. But our engineers enjoyed the way this community atmosphere existed side by side with bustling downtown core of this Provincial Capital.
“I was pleasantly surprised by the variety of restaurants, cafes, and breweries Whitehorse has to offer,” explains Linna. “Given Whitehorse’s population, I was expecting only a handful of eateries to choose from. Boy was I wrong!”
In fact, Linna and Merinda found more than enough to keep them busy each of their three days in the city.
“The MacBride Museum was very interesting to walk through,” recalls Linna. “We were also lucky enough to have Bob Baxter from Yukon Brewing give us a tour of the brewery and show us the engineering that was involved in their process!”
“One afternoon, Linna and I visited the Miles Canyon suspension footbridge and got to see one of the many amazing views Whitehorse has to offer!” says Merinda.
“I’ll remember to bring my hiking shoes and explore some nearby trails on my next visit,” chimes in Linna, laughing.
No good trip is complete without trying out a few favourite local feasts.
“Last but not least,” says Merinda, “Trying the famous bread pudding from Klondike Rib & Salmon was definitely a highlight.”
With so many highlights, the time flew by, and soon Merinda and Linna were back on a plane heading home to Surrey BC. But for these avid travelers, another trip to meet our community of suppliers, contractors and clients is surely just a short hop and adventure away.
