Improve Boiler Efficiency with Heatmizer
Heatmizer Boiler Economizers
Tri-Tech Sales supplies Heatmizer boiler economizers and flue gas heat-recovery systems for commercial and industrial boiler applications. Heatmizer equipment is designed to capture heat that would otherwise escape through the boiler stack and use it to preheat incoming feedwater.
By recovering this wasted heat, a Heatmizer economizer can reduce fuel consumption, lower stack temperatures, improve boiler efficiency, and decrease operating costs. Whether you are adding an economizer to an existing boiler or designing a complete new boiler system, our team can help identify a Heatmizer solution suited to your equipment, fuel, firing rate, and operating conditions.
What Is a Boiler Economizer?
A boiler economizer is a heat exchanger installed in the boiler’s exhaust path. Hot flue gas passes through the economizer before leaving the stack, transferring heat to the incoming boiler feedwater.
Preheating the feedwater reduces the amount of fuel the boiler must burn to produce steam or hot water. This improves overall system efficiency and helps facilities recover more value from the fuel they already purchase.
Boiler economizers are commonly used in facilities with consistent boiler loads, long operating hours, and steady feedwater demand.

Innovative Heat-Recovery Design
Heatmizer economizers are designed around quality, cost-effectiveness, and long-term serviceability. Their modular construction allows individual sections or components to be accessed and replaced without requiring the entire economizer to be removed. This can simplify maintenance, reduce downtime, and extend the useful life of the equipment.
The appropriate design depends on the boiler size, fuel type, stack temperature, feedwater conditions, operating schedule, and available installation space.
How Heatmizer Improves Boiler Efficiency
A significant amount of energy can leave a boiler through hot exhaust gas. Heatmizer captures a portion of this energy before it exits the stack.
The recovered heat is transferred to the boiler feedwater, reducing the temperature increase the boiler must provide. This can result in:
- Lower fuel use
- Reduced boiler operating costs
- Improved overall system efficiency
- Lower stack temperatures
- Reduced environmental impact
The actual savings depend on boiler load, operating hours, fuel cost, flue gas temperature, and incoming feedwater temperature.

Boiler Economizer Applications
Heatmizer economizers can support boiler systems across a broad range of commercial, institutional, and industrial facilities, including:
- Manufacturing and production plants
- Food and beverage processing facilities
- Hospitals and healthcare campuses
- Schools and universities
- Chemical and pharmaceutical plants
- Commercial laundries
- Refineries and energy facilities
- Municipal and institutional boiler rooms
Facilities with steady steam demand and extended boiler operating hours often have the greatest opportunity for heat recovery.
Request a Heatmizer Economizer Quote
To receive an accurate quote, provide as much information as possible about your boiler system. Helpful details include the boiler manufacturer and model, burner firing rate, fuel type, stack temperature, feedwater temperature, operating hours, steam load, stack dimensions, and photos of the existing equipment.
Our team will review the application and help identify a Heatmizer boiler economizer suited to your facility.
Contact Tri-Tech Sales today to request pricing or discuss your boiler heat-recovery opportunities.
Economizers for Existing Boilers
An economizer does not always require a complete boiler replacement. Heatmizer systems can often be engineered for installation on existing boilers when the application and available space allow.
Retrofitting an economizer may be worth considering when a facility has high stack temperatures, long boiler operating hours, rising fuel costs, or an efficiency-improvement goal.
Tri-Tech Sales can review your current boiler, burner, controls, stack arrangement, and feedwater system to determine whether an economizer retrofit is practical.

Serviceable Modular Construction
Heat-recovery equipment operates in a demanding environment and must be designed with maintenance in mind.
Heatmizer’s modular approach allows heat-transfer sections and other components to be serviced or replaced more easily than many single-piece designs. This helps facilities limit downtime and maintain reliable performance over the life of the economizer.
Routine inspection, cleaning, water-quality management, and proper boiler tuning remain important to maintaining efficient heat transfer.
Reducing Fuel Costs and Emissions
Improving boiler efficiency reduces the amount of fuel required to produce the same amount of steam or hot water.
Lower fuel use can help facilities reduce energy expenses and combustion-related emissions. This makes boiler economizers a practical option for organizations pursuing operating-cost reductions, sustainability goals, or energy-efficiency improvements.
Economizers may also work alongside burner upgrades, oxygen-trim controls, condensate recovery, and other boiler-room improvements.
Selecting the Right Boiler Economizer
Proper economizer selection requires a detailed understanding of the boiler and operating conditions.
Important factors include:
- Boiler horsepower and firing rate
- Fuel type
- Flue gas flow and temperature
- Feedwater flow and temperature
- Boiler operating schedule
- Stack arrangement
- Available installation space
- Expected boiler load
Tri-Tech Sales can work with Heatmizer to evaluate these conditions and recommend an appropriate system design.

Frequently Asked Questions About Heatmizer Economizers
How does a Heatmizer economizer save energy?
A Heatmizer economizer captures waste heat from the boiler’s flue gas, including both sensible and latent heat, and transfers it to the incoming feedwater. By recovering this waste heat, the economizer reduces the fuel requirements needed to bring the water to operating temperature, improving overall boiler efficiency and reducing heat loss.
Can a Heatmizer economizer be added to an existing boiler?
In many cases, yes. Retrofit feasibility depends on the boiler type, stack arrangement, available space, flue gas temperature, and feedwater system. Heatmizer economizers are built with modular, corrosion-resistant components, often equipped to handle condensing applications safely, making them suitable for many existing boilers.
How much can a boiler economizer reduce fuel costs?
Savings vary based on boiler load, operating hours, stack temperature, feedwater temperature, fuel cost, and economizer design. By lowering stack temperatures and recovering latent heat, economizers can reduce fuel requirements by 5% to 10%, helping facilities pay for the unit within a few years. Facilities with consistent boiler demand typically see the greatest benefit.
Are Heatmizer economizers easy to maintain?
Heatmizer uses a modular design intended to improve serviceability. Individual sections and components, such as tubes and fins, can be accessed or replaced more easily than with many one-piece systems. Regular maintenance helps prevent thermal shock and ensures optimal performance.
What information is needed to size a boiler economizer?
Sizing typically requires the boiler model, firing rate, fuel type, flue gas temperature, feedwater conditions, operating schedule, stack dimensions, and available installation space. It is critical to check these factors to ensure the economizer will handle your specific application effectively and safely.
