Get matched with top boiler installation pros in Lagunitas-Forest Knolls, CA

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

Modern boilers average around 20 years of use before failing, with some hitting 25 to 30 years. Older boilers, however, can last up to 50 years because they are often made from ultra-durable cast iron. Newer models are made from steel alloy and related components, which are great for withstanding high pressure levels and hot temperatures but offer a slightly lower life span.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

• When purchasing a high-efficiency system, your energy bills will be lower in the future.

• You may be eligible for special offers from your local energy company.

• Depending on the system, you may be eligible for HVAC rebates and tax credits.

• Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.
