The average cost to install an electric boiler is $5,000
Electric boiler installation costs range from $2,500 to $9,000, with the average cost being $5,000.
Your total costs depend on the type of boiler, the size of your home, the local climate, and your plumbing setup.

Before you decide on an electric boiler, set a realistic budget. Most installations fall within the range of $3,000 and $7,000, and many homeowners spend an average of $5,000. Depending on the brand, size, and local climate demands, total costs can range from as low as $2,500 to as high as $9,000.
Electric models are more energy-efficient than gas or wood units and fit neatly into tight spaces because they don’t need a flue. The trade-off is a slightly slower heat-up time, so make sure the boiler’s output meets your home’s heating needs.
Electric Boiler Installation Cost Factors
Several factors influence the cost of installing an electric boiler, including your location, the size of your home, and whether you already have the necessary plumbing.
Boiler Type
Electric boilers range in price from $2,500 to $9,000, with variations depending on the brand and output. Larger homes—or properties in colder regions—require higher-capacity units to maintain comfortable temperatures in their rooms.
Home Size
Your square footage drives boiler size: the more space you heat, the larger—and therefore pricier—the unit. Here’s a look at how much electric boiler installation costs based on your home size and square footage:
| Home Size (Sq. Ft.) | Boiler Size (kW) | Average Installation Cost Range |
|---|---|---|
| Up to 1,000 | 10 | $2,500–$3,500 |
| 1,000–1,500 | 15 | $3,000–$5,000 |
| 1,500–2,000 | 20 | $4,000–$6,500 |
| 2,500–3,000 | 30 | $6,000–$9,000 |
Labor
When your home already has the necessary plumbing, expect labor costs to range from $2,500 to $6,000. Adding new plumbing will increase that figure. Plan on hiring a licensed HVAC technician—most charge $75 to $150 per hour or quote a flat rate that covers a two-person crew.
Climate
Colder climates call for higher-output boilers. Since electric models can be more expensive to operate than gas, oil, or wood units, many homeowners in frigid regions opt for alternative fuels unless their homes are well-insulated.
Plumbing
Plan on adding to your bill if your home requires new plumbing lines before the boiler installation. Plumbers charge $45 to $200 per hour, or a $700 flat rate fee for the service.
DIY Electric Boiler Installation vs. Hiring a Pro
For most homeowners, hiring a licensed HVAC pro is the safest and most cost-effective choice. A botched installation can void the warranty, damage the unit, or create leaks and electrical hazards.

Budgeting Tips for Electric Boiler Installation
To keep costs down when installing an electric boiler, consider the following tips:
Compare quotes from multiple HVAC contractors to find competitive pricing and identify any unnecessary upsells.
Select the ideal boiler size for your home—oversized units incur higher upfront costs and may waste energy over time.
Look for rebates or incentives from utility companies or local governments that promote energy-efficient upgrades.
Install during the off-season (spring or fall) when demand for HVAC services is lower and discounts may be available.
Bundle installation with other upgrades (like a new thermostat or insulation improvements) to save on labor costs.
