This article was created using automation technology and thoroughly fact-checked and edited by an Angi Editor in accordance with our AI policy.

The average cost of electric boiler installation is $5,000, with most homeowners spending between $3,000 and $7,000. Prices depend on boiler size, type, labor, and any required electrical upgrades. Unlike gas systems, electric boilers don’t require venting, but installation costs can rise for larger homes or complex setups.

For homeowners, understanding these costs helps you budget for a comfortable, energy-efficient home.

Cost by Size of Electric Boiler 

The size of your electric boiler has a direct impact on installation cost. Boiler capacity is measured in kilowatts (kW) or British Thermal Units (BTU), and most residential electric boilers range from 10 kW to 30 kW. Larger boilers, which are required for larger homes or those with multiple heating zones, are more expensive to purchase and install.

Choosing the right size is important—a unit that’s too small won’t keep your home warm, while an oversized boiler can waste energy and increase upfront costs. If your home has high ceilings, poor insulation, or a complex layout, you may need a larger-capacity boiler, which can increase both equipment and installation costs.

Electric Boiler Installation Cost by Type

The type of electric boiler you choose also affects installation cost. There are several main options: standard (heat-only), combination (heat and hot water), system boilers, and heat-only units. Each has its own price point and installation complexity.

Combi boilers, which provide both space heating and hot water, tend to cost more to install but save space and may reduce plumbing needs. System boilers are suitable for larger homes and can be more expensive due to their additional components. Heat-only units are often the most affordable but may require a separate hot water tank. Features like smart controls and integrated zoning increase both convenience and installation cost.

Cost by Location

Your location influences the cost of electric boiler installation due to differences in labor rates, material prices, and permitting requirements. Urban areas often have higher labor costs, while rural locations may face delivery surcharges or limited contractor availability. Local climate can also play a role—colder regions may require larger boilers or insulation upgrades.

Permit and inspection fees vary by city or state, sometimes adding several hundred dollars to the cost of your project. Always check with your local municipality for specific requirements before starting installation.

Electric Boiler Installation Cost Factors

Understanding what drives the cost of electric boiler installation can help you make informed choices and avoid surprises.

Labor

Labor is a significant portion of your total cost. Licensed HVAC contractors and electricians are required for the installation of electric boilers. Hourly rates range from $75 to $150, with minimum service fees common in many areas. Labor costs are higher in urban regions and for contractors with specialized experience.

New installations cost more than replacements, as they may require additional wiring or site preparation. Complex projects, such as multi-zone heating or installations in tight spaces, will increase labor time and cost.

Permits

Permits are required in most municipalities for the installation of electric boilers. Fees range from $50 to $500, depending on your location and the scope of work. Inspections may be required before and after installation, which can increase the total cost.

Skipping permits can result in fines, insurance issues, and problems when selling your home. Always confirm permit requirements before starting.

Additional Features

Upgrades such as smart thermostats, zoning controls, and Wi-Fi integration can increase installation costs. Additional system components—such as improved insulation, water treatment systems, or expansion tanks—also contribute to your final bill.

Integrating your electric boiler with an existing heating system or smart home platform may require additional labor or custom setup, resulting in higher costs. Optional add-ons should be considered based on your comfort needs and budget.

Service Add-Ons

Several other factors can impact your installation cost:

• Retrofitting an electric boiler into an older home costs more than new construction.

• Installing in a basement, utility closet, or other hard-to-reach area can increase labor time.

• Removing an old boiler, upgrading electrical panels, or arranging for special delivery can add hundreds to thousands of dollars to the cost.

• Post-installation cleanup and debris removal may be billed separately.

• Engineering or design fees for custom-designed systems.

• Required inspections, either by your municipality or utility, can add to the final total.

Additional Costs to Consider

Beyond installation, you’ll want to budget for warranties, operating costs, maintenance, taxes, and insurance.

Warranties

Most electric boilers come with a manufacturer's warranty covering parts for five to 10 years. Some brands offer extended warranties for an extra $200 to $600, which may include labor or service calls. Strong warranty terms provide peace of mind and can reduce long-term repair costs.

Warranties often cover major components but may exclude labor or certain wear items. Always review warranty details before purchasing.

Operating Costs

Electric boilers are highly efficient, converting nearly all input electricity into heat. However, electricity rates tend to be higher than natural gas. On average, expect to spend between $1,200 and $2,500 per year on electricity for heating, depending on the size of your home, local climate, and insulation quality.

Your boiler’s efficiency affects operating costs, the level of insulation in your home, and your heating habits. To estimate your monthly or yearly energy expense, multiply your boiler’s kW rating by the number of hours it runs and your local electricity rate.

Maintenance

Annual maintenance for an electric boiler is less involved than for a gas or oil unit. Common tasks include checking electrical connections, cleaning components, and inspecting safety devices. Professional servicing costs $100 to $300 per year, while basic DIY maintenance (like dusting vents) can help keep things running smoothly.

Common repairs, such as replacing a thermostat or heating element, range from $150 to $500. Regular boiler maintenance helps extend the lifespan of your system and ensures safe, efficient operation.

Taxes

You may be required to pay sales tax on the equipment and installation, depending on your state's tax laws. Some states also charge local or special taxes for home improvements. On the positive side, tax incentives or rebates may be available for installing energy-efficient electric boilers; check with your local utility or government for current offers.

Insurance

Installing a new electric boiler can affect your homeowners' insurance premiums. Some insurers require proof of professional installation or updated electrical systems. Make sure your new system is included in your coverage and that your contractor carries liability insurance for the work.

DIY Electric Boiler Installation vs. Hiring a Pro

Some homeowners consider installing an electric boiler themselves to save on labor costs. While DIY installation can save $2,000 to $4,000 on labor, it requires advanced electrical and plumbing skills, specialized tools, and a deep understanding of building codes.

DIY projects can take several days and may void the manufacturer’s warranty if not done to code. Mistakes can lead to safety hazards, property damage, or failed inspections. In many areas, a licensed professional is required by law for boiler installations, especially when upgrading electrical panels or wiring.

Attempting a DIY installation is best left to those with professional-level skills. For most homeowners, hiring a qualified boiler installer near you ensures a safe, efficient, and code-compliant installation.

Electric Boiler Replacement vs. Repair

Deciding between replacing and repairing your electric boiler depends on its age, condition, and the extent of its repair needs. If your boiler is less than 10 years old and the issue is minor, such as a faulty thermostat or heating element, the cost of boiler repairs ranges from $150 to $700.

If the boiler is nearing the end of its expected lifespan (12 to 15 years) or if repair costs exceed 50% of the price of a new unit, replacement is a better investment. Signs you need a replacement include frequent breakdowns, rising energy bills, or major leaks.

Using the 50% rule—replacing the boiler if repair costs exceed half the price of a new installation—can help you make an informed decision.

Does an Electric Boiler Add Value to Your Home?

Installing a new electric boiler can boost your home’s value and appeal, especially if you’re upgrading from an older, less efficient system. The average return on investment (ROI) for electric boiler installation depends on your local market and the quality of the installation.

Upgrading to an efficient electric boiler can improve comfort, lower energy bills, and enhance safety. Compared to other heating upgrades, electric boilers offer the added benefit of universal design—they can be installed in homes without gas service and don’t require venting. Enhanced efficiency and modern controls also make your home more attractive to future buyers.
