Home & Garden/Heating & Cooling costs cover boiler installation, including converting an oil boiler to gas. This energy-efficient mode of heating works by directing cold water through heated pipes before disbursing steam as a heating source.

You cannot figure the cost of a boiler installation instantly. Before you determine a price, you need to review a number of factors that affect pricing. Not only must you survey the best gas boiler brands, but you also need to review used boilers for sale. Also, check the pricing for accessories, such as boiler thermostats. The following information can assist you in making a clear-cut decision with respect to cost.

Pricing Boilers by Type

Pricing is easier if you first determine the type of boiler you wish to install. Installation may run from $3,500 to $7,700. Most homeowners pay around $5,500, on average. Naturally, the price you pay will depend on the boiler type, as several configurations are available online. High-efficiency models save on energy and therefore are generally priced higher.

Combination Boilers - Combination or combi boilers work out well in small residences, such as apartment homes. The tankless boiler receives water from the outside mains and usually is designed without a tank. While a small tank can be included, homeowners who wish to optimize space choose the tankless design. Any combination boiler that includes the tank is called a combi-storage boiler.

Combi boilers supply heat or hot water with no waiting time. They work best in apartments with one or two occupants, as overuse can drop the water pressure. An average combi boiler runs about $1,300 to install.

System Boilers - System boilers, also known as sealed-system boilers, provide steady water pressure and fast delivery to one or more faucets. The boilers store water inside a cylinder where it is heated first before being converted to steam or delivered to faucets. These boilers work well in mid-sized households. While the heat is delivered quickly, expect a small wait time. The average cost for this system runs around $1,500.

Conventional Boiler Systems - Also called standard boilers, conventional boilers heat water quickly in the pipes, which run through a tank and deliver hot water to faucets or floor heating systems. Larger buildings frequently use these boilers. The average cost for this type of boiler system runs around $3,500.

Pricing Boilers by Fuel Use

Boilers are compared for the cost by their fuel usage as well. Most boilers run on natural gas. However, they may be fueled by oil, electricity, geothermal energy, or wood. Alternative fuel systems, produce a cleaner exhaust and average around $2,300 to install. Other units run from $2,500 to $5,000, depending on the heating space and the number of people using the boiler.

The Costs Associated with Boiler Replacements

Repairs for boilers usually average $300 to $500, and typically involve switching out heat exchangers, lines, or burners. The replacement cost for a standard boiler that runs on natural gas is around $4,000. Higher efficiency models cost around $7,500.

Boiler Replacement Costs

Boiler repairs typically cost between $300 and $500 and usually involve replacing key elements, such as heat exchangers, burners, or lines. Over time, the use of water and fuel can corrode a boiler's components, which leads to an eventual replacement.
