How Much Does Boiler Replacement Cost in Indianapolis? [2025 Data]

The average boiler replacement cost in Indianapolis, IN, is $1,912, with most homeowners spending between $1,750 and $2,074. A working boiler is essential for surviving Indiana’s cold and often snowy winters, so it’s important to understand the factors that can influence the price. These include size, fuel type, boiler type, and local labor rates.

Boiler Replacement Cost Factors 

If you’re looking to replace your boiler in Indianapolis, the price depends on a variety of factors. Here are the main ones.  

Size

The median home size in Indianapolis is 2,100 to 2,200 square feet. To heat that amount of space in Indiana’s climate, a boiler should have a capacity of 60,000 to 90,000 BTUs.

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 Indianapolis, IN, for the most accurate estimate.

Fuel Type

The most common fuel used for boilers in Indianapolis, IN, 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. 

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.

Climate Zone

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

Boiler installation isn’t something you should DIY. Mistakes could have dangerous consequences like electrical shock, fire, explosion, or a gas leak. Instead, contact a HVAC professional to do the job for you. This local boiler installation pro should be qualified, licensed, and insured. 

In Indianapolis, the labor cost for a standard boiler replacement can range from $1,500 to $4,000, with the average being $2,200. The cost depends on the complexity of the job, the contractor's experience, the ease of removing the old boiler, and more.

Also, to ensure your boiler replacement meets local safety codes, the City of Indianapolis requires a permit. Expect to pay $150 in permit costs. Your contractor should handle the application process, but it's a good idea to confirm with them that the permit is in place.

Does Boiler Replacement Increase Home Value?

A new boiler is an attractive selling point for buyers who’ll like knowing their boiler will get them through the Indianapolis winters. It also signals that the system won’t need to be replaced any time soon. Because of this, a new boiler can increase the value of your Indiana home by 3% to 5%. You’ll see the most ROI if you opt for a high-efficiency boiler—these also lead to substantial savings on utility bills.
