Boiler Replacement Cost Factors 

Boiler replacement costs in Dallas, TX, depend on several different factors, especially the size of your home and the type of boiler you install.

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 Dallas, TX, for the most accurate estimate.

Fuel Type

The most common fuel used for boilers in Dallas, TX, 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

Be sure to budget $2,000 for labor costs for boiler replacement. Labor makes up a significant portion of the cost to replace a boiler because this project is complex and can be dangerous. Any mistakes can lead to gas leaks or even explosions. Get at least three quotes from local HVAC pros, then choose someone with fair pricing, good reviews, and plenty of experience working with boilers.

Does Boiler Replacement Increase Home Value?

In a mild climate like the one in Dallas, boiler or furnace replacements have less impact on home value than in cities with cold climates. Still, replacing a boiler can increase home value by 3% to 5%, plus you’ll save 10% to 20% on your heating bills by switching to a more modern, efficient boiler.
