If your boiler is inefficient, worn out, or just plain old, the simplest solution is to replace it with a modern, high-efficiency model. Many homes in neighborhoods like Capitol Hill, Park Hill, and Washington Park still rely on older hydronic or radiant heating systems. Old coal burners that were switched over to oil or gas are the prime candidates for boiler replacement. Though newer systems may be more efficient, they are often still likely to be oversized and can often be modified to lower their operating capacity.

When To Replace Your Boiler
How do you know when it’s time to contact a boiler installer to replace your current system? Your boiler is nearing the end of its lifespan and requires replacement if the system is:
- 25+ years old
- Rated anything less than an A
- Consistently breaks down
- Making loud noises
- Has a yellow flame instead of blue
- Uneven heating or cold spots
- Leaking
An outdated, failing boiler won’t keep your home warm and comfortable, and it can also lead to steadily rising energy bills and worsening boiler efficiency. For this reason, we recommend considering a new boiler as an investment rather than just an expense.

High-Efficiency Boiler Replacements Save You Money
Whether you’re already using a boiler or currently rely on a furnace or heat pump to keep your home warm, a new boiler may save you money on your utility bills. Boilers are a highly efficient way to heat a space, making them a great choice for Denver’s high altitude and cold climate, where reliable heating is a necessity.
You don’t necessarily have to invest in a boiler replacement right away. We also provide comprehensive boiler repair services to help keep your system running smoothly as long as possible.
When your boiler suddenly breaks or stops working to its fullest potential, it’s easy to become frustrated about the lack of comfort in your home. That’s why our main goal at Sanders and Johnson is to restore your comfort, rid you of your frustrations, and provide you with the best boiler repair services available near you in and around Denver. Rest assured that when anything goes wrong, we’re the team you want on your side to fix it…guaranteed!
Believe it or not, system failure is not the only way you can tell that your boiler is in need of a repair. In fact, even small performance issues can also indicate that your boiler is having trouble keeping up. Many of these issues can be addressed by our expert HVAC technicians, but keep in mind that once your boiler repair costs begin to exceed half of the cost of a new unit, it’s probably time for a replacement.

Frequently Asked Questions
What types of boilers are available in Denver?
Boilers come in many different types, including natural gas, electric, and propane, heat-only or combination, as well as a variety of sizes. There are many factors to consider, and not all boilers will perform well in your specific space. To ensure you choose the right model for you, we suggest contacting a professional for help.
How long do boilers last in Denver?
Boilers can last anywhere from 25 to 35 years, depending on their size, usage, and the level of maintenance they receive each year. To get the most out of your boiler, have it professionally maintained, cleaned, and inspected at least once a year, ideally in the fall season before you need to use it daily.
Is it better to repair or replace my boiler?
A boiler that’s within its average lifespan, has normal energy efficiency, and only faces occasional problems may be better to repair rather than replace. However, if the boiler is very old, frequently breaks down, or is highly inefficient, it probably makes more sense to replace it than to keep repairing it.
How often does my boiler need to be serviced?
For the best results, you should have your boiler professionally serviced once a year. Regular maintenance helps maintain high efficiency, avoid sudden shutdowns, and extend the boiler’s lifespan.
