Our Recent Triangle Tube Boiler Replacement Job in Denver, CO
With boilers installed in a significant percentage of homes in metro Denver and nearby mountain communities, our experts see plenty of issues that can affect comfort and safety. While Sanders & Johnson aims to provide solutions through diagnostics and repairs, sometimes we’re faced with a system that’s beyond saving and needs a full boiler replacement.
Find out how we helped a local homeowner when Triangle Tube boiler repair was no longer possible, including how we solved the problem, the new system benefits, and the total project cost.
The problem the homeowner was facing
A Denver homeowner reached out to our team for help after running into issues with her Triangle Tube (TT) boiler. She paid another company $30,000 to install it a couple of years ago, yet it already needed a new wiring harness.
The situation became complicated when she discovered the replacement part was no longer available. Triangle Tube was going out of business, making it nearly impossible to source the right components to keep her boiler operational.
Triangle Tube released equipment without sufficient research, testing, and design, resulting in recalls affecting almost every model of its boilers. Most of their equipment is run by control boards on their 17th revision, with ongoing performance and reliability problems. Triangle Tube was eventually forced to file for bankruptcy after serious safety issues emerged, including carbon monoxide leaks that resulted in multiple fatalities.
Now, homeowners are left with expensive, faulty systems that are nearly impossible to repair or maintain. We’ve completed at least three more TT boiler replacements in the last few weeks after customers reported a faulty or failing sensor. With no Triangle Tube replacement parts available, they have no other choice but to replace the entire boiler unit.
How we solved the problem
Given safety concerns with Triangle Tube’s products, the customer’s best option was to replace the entire system.
- We removed the faulty Triangle Tube boiler and replaced it with a safe, reputable brand that runs better, lasts longer, and is far safer than her previous unit.
- We were able to reuse portions of her existing piping, keeping repiping costs to a minimum and reducing the stress of this replacement project.
What Our Technicians Installed
Our experts replaced the customer’s existing Triangle Tube system with a brand-new Lochinvar Noble 150 Boiler. These high-efficiency boilers are compact, wall-mountable, and designed for long-lasting performance in Denver’s chilly winter weather.
Some of their top benefits include:
- 95% AFUE efficiency for lower energy costs.
- Rapid hot water delivery of up to 4.8 gallons per minute.
- Adaptable burners that reduce cycling and improve efficiency.
- Simple, user-friendly controls.
- Corrosion-resistant heat exchanger.
- 10-year limited manufacturer warranty.
Lochinvar Noble 150 boilers are among our top recommendations for Denver homeowners who want to save space, reduce utility costs, and enjoy reliable, on-demand hot water.
Cost of the Project
The original estimate for this boiler replacement project was several thousand dollars. Because we were able to use some of the existing piping, the homeowner avoided repiping and reduced her upfront costs.
Depending on the scope of work, boiler replacement projects typically can cost several thousand dollars. While this is a major investment, replacing a faulty, unreliable Triangle Tube boiler with a Lochinvar Noble 150 system delivers long-term value and peace of mind through improved safety and reliability. Homeowners often see fewer repairs and a significant reduction in their utility costs, and don’t have to worry about whether replacement parts are available.
The top factors that determine boiler replacement costs in Denver include:
- The equipment type: Higher-efficiency or specialty boilers come with higher upfront costs.
- Repiping needs: Reusing existing piping can save money, while a complete repiping increases labor and material costs.
- Fuel type: Natural gas, propane, and electric boilers have different installation requirements and costs.
- Home size: Larger homes often require higher-capacity boilers, increasing installation and equipment fees.
- Venting requirements: Some older homes may require updates to vents, flues, or chimneys, which can increase the total project cost.
- System complexity: Installing a multi-zone heating or radiant floor heating system comes with higher labor and equipment costs.
- Disposal of existing equipment: The safe removal and disposal of existing boiler units and piping adds to total replacement costs.
- Permits and inspections: Local codes, permits, and inspections may incur additional fees that affect the total cost.

Long-Term Benefits of the Boiler Replacement
Replacing an outdated or faulty boiler improves your home comfort, efficiency, and overall value. Older or faulty boilers, like many Triangle Tube models, are unreliable, harder to repair, and can put your family at risk of dangerous carbon monoxide leaks or electrical hazards. Upgrading to a modern system eliminates those concerns while offering long-term safety.
Some of the top benefits Denver homeowners experience after upgrading their systems include:
- Energy savings: Modern boilers typically have AFUE ratings of 80% to 96%, meaning they use less fuel and help reduce utility costs.
- Better reliability: New boilers are less prone to unexpected repairs or breakdowns, giving you peace of mind during Denver’s snowy winters.
- Improved comfort: Installing a new boiler offers more consistent home heating and reliable hot water when you need it most.
- Increased property value: Upgraded heating systems can be a major selling point for buyers, providing a significant return on your investment.
- Updated safety features: Features like sealed combustion and advanced control systems reduce your carbon footprint and help keep your household safe.
- Faster hot water delivery: Newer boilers have higher flow rates, delivering hot water to your taps much faster than older systems.
- Smart system integration: Some modern boilers can be integrated with your home’s smart system for easy scheduling and monitoring.
- More space: Compact systems like the Lochinvar Noble 150 take up less room than bulky, older units, freeing up valuable space in your utility room.
