Boiler Replacement Cost Factors
To beat the long winter chill in Denver, you can get a new boiler that can keep your home reliably warm. But how much does boiler replacement cost in Denver, CO? The price depends on the following factors.
Size
You can estimate the cost of your boiler by your home’s square footage and boiler capacity using the table below. However, call an HVAC pro in Denver, CO, for the most accurate estimate.
| Home Size (Sq. Ft.) | Boiler Capacity (BTUs) | Cost |
|---|---|---|
| 1,000 | 30,000–45,000 | $580–$4,790 |
| 1,200 | 36,000–60,000 | $2,220–$5,750 |
| 1,500 | 45,000–75,000 | $2,770–$7,190 |
| 1,800 | 54,000–82,500 | $3,320–$8,620 |
| 2,000 | 60,000–90,000 | $3,690–$9,580 |
| 2,250 | 67,500–102,000 | $4,150–$10,772 |
| 2,500 | 75,000–113,000 | $4,610–$11,970 |
| 3,000 | 90,000–135,000 | $5,540–$16,000 |
Fuel Type
The most common fuel used for boilers in Denver, CO, is natural gas. The fuel type you choose will have a major impact on both your ongoing costs and how much you pay for a new boiler.
Oil boiler: Oil burns hotter than gas, so oil boilers provide more heat and are better in colder climates. However, oil boilers require more maintenance than gas options, so keep things like long-term maintenance costs in mind before buying.
Gas and propane boiler: Propane and natural gas are common options for heating homes. In addition to the unit price, installation costs $1,000 to $3,000 and requires new exhaust lines, drains, and fuel lines.
Electric: Electric boilers are highly efficient and don't require some of the components that gas and oil boilers need, like exhaust vents. They take a long time to heat up but are an attractive option for tiny homes in warm climates.
Wood: Large, outdoor, wood-fueled boilers are good options for rural areas that have easy access to wood.
| Fuel Type | Cost |
|---|---|
| Oil | $4,150–$10,772 |
| Gas/propane | $4,150–$10,772 |
| Electric | $1,800–$7,361 |
| Wood | $7,361–$16,000 |
System Type
Boilers are broken out by fuel type, but they can also vary in other ways—like their system types.
Standard or conventional boilers: These boilers work by quickly heating water in pipes and sending it to your taps. Standard units are one of the most popular choices for homeowners in large homes and those with floor heating systems.
Combination boilers: Combination boilers are popular because they’ll give you access to hot water quickly. However, the supply tends to be limited due to the lack of a storage tank.
System boilers: These work by keeping high-pressure hot water in a sealed cylinder, where it can be sent to multiple taps within your home simultaneously.
High-efficiency boilers: High-efficiency boilers are up to 98% efficient, which accounts for thousands of dollars in savings over the boiler's life. Standard boilers are around 80% efficient, making them ideal for cold climates.
| Type | Cost | Pros | Cons |
|---|---|---|---|
| Standard | $4,150–$10,772 | Easy maintenance | Less energy-efficient |
| Combination | $4,150–$10,772 | Fast heating | Limited output |
| System | $4,150–$7,361 | Quick, efficient heating | Takes up more space |
| High-efficiency | $7,361–$16,000 | Long-term cost savings | Higher installation cost |

The capacity of your boiler (in BTUs) depends on your region and climate. Warmer climates make it much easier to heat water, even for larger houses, so fewer BTUs are required. You can estimate your necessary BTUs by finding out which climate zone you live in.
HVAC Pro Costs
Hiring an HVAC pro for boiler installation costs $75 to $200 per hour, per worker, with most installs taking between a few hours and a few days. You should always leave boiler installation to a pro. Even if you’re pretty handy, DIYing could void your boiler warranty. If something goes wrong with the boiler, homeowners insurance won’t cover boilers that aren’t installed by certified pros.
Does Boiler Replacement Increase Home Value?
When it’s time to replace your boiler, investing in an upgrade can lead to a 3% to 5% increase in home value. Older boilers have efficiency ratings as low as 56%, new standard boilers can be around 80% efficient, and high-efficiency models can be 98% efficient. As such, upgrading to a new boiler can save you (or the person who buys your home) money month after month on heating costs.
