How much does a new boiler cost?

Prices include labor and materials.

Boiler replacement costs can fluctuate based on various factors, such as:

• The type of boiler system you choose
• The cost of labor and materials
• The complexity of the project
• Your household's heating needs
• The boiler’s size or heating capacity (BTU)
• And much more

Gas boilers tend to be more efficient than other types of boilers. However, there are a few considerations to keep in mind when choosing between natural gas and propane.

If you want to install a natural gas boiler, you'll need to have a natural gas distribution in your area. If not, a propane boiler may be a better option since you can have propane delivered to your home via a truck. Just know that propane is usually more expensive than natural gas.

Prices include labor and materials. Note: BTU/h stands for British Thermal Units per Hour. 

Electric boilers are another efficient option — but their operating costs may be high compared to gas boilers. That's because electricity is often more expensive than gas, but it ultimately depends on energy costs in your area. For this reason, the Department of Energy recommends homeowners consider a heat pump for electric heating instead.

With an electric steam boiler, it's important to remember this: they're less efficient than hot water boilers. Keep this in mind, and consult a professional if you're stuck between these two options for your home.

If your area doesn't have much access to natural gas, you might also consider an oil-fired boiler. You'll need to factor in the ongoing cost of having heating oil delivered and stored at your home.

Several elements can affect how much it will cost to install a new gas, electric, or oil boiler. Keep reading to learn more about these factors, or start gathering price quotes from professionals in your area.

When it comes to considering the cost of a new boiler, several factors can impact your budget. These considerations go beyond the initial installation and can significantly influence the overall cost of your project.

Here's a quick breakdown of the key cost factors to keep in mind:

Labor costs and service fees. 

Labor, service fees, and other associated boiler installation costs can vary depending on your location and the complexity of the job. Hiring a qualified and experienced professional to install your boiler is essential, as it ensures a safe and efficient installation.

Material and equipment costs. 

The type and quality of the boiler system you choose can significantly affect your costs. High-efficiency boilers, for example, may come with a higher price tag but can result in long-term energy savings.

Type of boiler system. 

The type of boiler system you select may also impact costs. For example, you may want to consider a combination boiler instead of a standard boiler.

A combination (or combi) boiler can heat your home as well as your domestic water. Domestic water refers to the water you use for cleaning, drinking, and watering your plants. Chat with your contractor to get a better understanding of pricing for these types of boilers.

Boiler size or heating capacity.

When we talk about a boiler's size, we're referring to its output or heating capacity — not its physical dimensions. British thermal units (BTUs) are used to explain how much heat a boiler can produce. The more BTUs, the more expensive your unit may be.

A professional will need to consider a home's square footage, insulation, windows, and more to properly size your boiler.

Annual Fuel Utilization Efficiency (AFUE).

AFUE is a measure of a boiler's (or furnace's) efficiency in converting the energy content of its fuel into usable heat over the course of a year. Expressed as a percentage, a higher AFUE rating indicates greater efficiency — and it will likely cost more to buy. However, you may enjoy more energy savings (and lower operating costs) in the long run.

Removing the existing boiler system.

If you're replacing an existing boiler system, there may be additional costs associated with removing the old system and components. This can involve labor fees and disposal costs. Make sure you ask your HVAC technician to include these estimates in your quote.

Electrical considerations.

If your new electric boiler requires electrical modifications or rewiring, note that this can add to the overall cost of the installation.

Gas and fuel considerations. 

The type of fuel you're considering — whether it's natural gas, oil, or electricity — can affect the cost of your new boiler. Gas lines may also need to be installed or adapted to accommodate the new system. 

By carefully weighing these factors and getting quotes from local professionals, you can develop a comprehensive budget for your new boiler installation project. This will ensure you're well prepared for the costs associated with this essential home improvement.

When it comes to replacing or installing a new boiler, homeowners often look for ways to save money while also ensuring a reliable heating system. Here are some tips to help you manage your budget and make the most cost-effective choices:

• Choose energy-efficient models. Consider investing in a high-efficiency boiler. While it may have a higher upfront cost, it will likely lead to long-term savings on your energy bills. High-efficiency boilers are designed to use less fuel to produce the same amount of heat, making them more cost-effective in the long run.
• Opt for energy-efficient upgrades. If you have an older boiler system, you may still be able to improve its efficiency by adding insulation or upgrading the controls. These upgrades are generally more budget-friendly than replacing the entire system. Chat with an HVAC professional to see what the best option is.
• Get competitive quotes. When it's time for a replacement, obtain multiple quotes from qualified local professionals. Comparing quotes will help you find the most cost-effective option for your needs. Don't forget to consider the boiler's quality and warranty, along with the installer's reputation.
• Take advantage of government incentives. Check if there are any local or federal incentives, rebates, or tax credits for installing energy-efficient boilers. These programs can significantly reduce your upfront costs.
• Consider seasonal installation. Try to schedule your boiler replacement during the off-season, typically in the spring or summer. Demand is often lower during these times, which can lead to lower installation costs.
• Be proactive when it comes to repairs. If your current boiler is showing signs of wear and tear, opt for the necessary repairs as soon as possible. Timely fixes can prevent more significant issues down the road, potentially delaying the need for a full replacement.
• Perform regular maintenance. One of the best ways to save money on boiler replacement is to maintain your current system properly. Regular service and maintenance can extend the life of your boiler, delaying the need for a costly replacement.

By implementing these cost-saving tips, you can enjoy efficient and reliable heating while keeping your budget in check.

Heating a house with a boiler has its advantages, particularly in terms of comfort and energy efficiency. However, the cost-effectiveness depends on various factors such as the type of boiler you have, fuel type, insulation within your home, and more.

Undertaking a boiler replacement or installation project on your own is ill-advised — especially if you don't have the proper license, experience, and skills.

Beyond the fuel utilized by boilers, these systems contain a significant volume of water, making any leaks or spills potentially harmful to your property. DIY installations can lead to costly errors and potential safety hazards.

For these reasons, it's best to hire a licensed HVAC professional to install your boiler or any other type of heating system.

While plumbers may be able to perform some boiler-related tasks, replacing a boiler is typically a job for a heating contractor or HVAC technician.

When hiring a pro, look for certifications related to heating systems and boiler installation to ensure they're qualified for the job. Check with your state to see what licenses or certifications are required to install and repair boilers.

Whether it's worth replacing your boiler depends on your specific circumstances. Consider the following benefits and drawbacks to help you make an informed decision:

• Benefits: improved energy efficiency, reduced heating costs, and enhanced home comfort.
• Drawbacks: it can be expensive to buy, and there may be more efficient options to consider.

Depending on your budget and needs, you may want to consider other heating systems before deciding to install a new boiler system. Consult an HVAC professional to see if a furnace, heat pump, or solar heating may be a better option for you.
