Boiler Replacement Cost Estimator by Home Size

The cost of your boiler replacement is also influenced by the size of your home. A larger home with multiple rooms and levels will require a more robust boiler to effectively heat the entire space, resulting in higher costs than a smaller one-story home with limited square footage.

To give an example, uma 45,000 BTU system is typically needed for a 1,500-square-foot home and could cost anywhere from $4,500 para $6,800. No entanto, a larger 3,000-square-foot home would require a more powerful 90,000 BTU system, which could cost between $9,300 e $15,500.

*Note: The BTU rating is the amount of energy it takes to heat one pound of water by one degree Fahrenheit. The higher the BTU rating, the more powerful and expensive the boiler will be.

Here is a breakdown of the average cost by BTU rating and home size:

Home Size (sq. Ft.) BTU Average Cost Range
Up to 1,500 40,000 – 60,000 $3,500 – $6,000
1,500 – 2,500 60,000 – 80,000 $4,000 – $7,500
2,500 – 3,500 80,000 – 100,000 $6,000 – $9,000
Sobre 3,500 100,000 – 200,000 $8,000 – $12,000

Note: The above estimates are based on a standard gas boiler replacement and do not include additional costs for the installation of an oil or electric boiler, or any required piping or gas line work. The actual cost of boiler replacement will depend on several factors such as the type and size of the boiler, the brand, and any necessary installation requirements. It is always best to consult with a licensed professional for an accurate estimate.

Cost of Boiler by Fuel Type

Tipo de combustível Average Cost
Natural Gas $3,700 – $7,500
Propane $4,500 – $10,000
Óleo $5,500 – $12,500
Elétrico $2,500 – $7,500

Note: The actual cost may vary based on factors such as location, efficiency rating, and labor costs.

When it comes to boiler replacement, the type of fuel you use can also impact the total cost. Different fuels have varying costs, and some boilers may be more efficient than others. Here’s a breakdown of the average replacement costs for different types of fuel:

  1. Natural Gas: Natural gas is a common fuel source for boilers, and it’s also one of the most affordable options. Na média, a natural gas boiler replacement costs around $5,500 para $10,000.
  2. Propane: Propane is another popular fuel source for boilers, especially in areas where natural gas is not readily available. No entanto, propane tends to be more expensive than natural gas. A propane boiler replacement can cost between $6,000 para $12,000.
  3. Óleo: Oil boilers are often used in older homes, and while they can be efficient, they tend to be more expensive to operate. The average cost of an oil boiler replacement is around $7,000 para $13,000.
  4. Elétrico: Electric boilers are less common than other fuel types, but they can be a good option for homes that don’t have access to gas or oil. The cost of an electric boiler replacement ranges from $1,000 para $6,000, depending on the size and type of boiler.

It’s important to keep in mind that fuel costs can fluctuate based on factors like supply and demand, so these prices are just averages and may not reflect current market conditions.
