Boiler Installation Cost by Home Size 

Modern houses constructed with energy efficiency in mind keep the heat in, meaning a low-capacity boiler can show great results. Poorly insulated homes, on the other hand, may call for a unit with the highest capacity to maintain a comfortable environment. Overall, depending on your local weather conditions, you need a heating system producing 30 to 45 BTU (British thermal units) for each square foot of the property. It’s common knowledge that high-efficient boilers cost twice or three times more than standard ones. 

Homeowners in Florida, California, or other states with warm climates can go for a boiler with 75,000 BTU capacity for a 2,500-square-foot house. However, those residing in Connecticut, Maine, or Massachusetts will have to purchase a boiler with 113,000 BTU for the same-size home. 

The cost of a new boiler by home size

Home size	Boiler capacity	Average cost
1,000 sq. ft.	30,000 - 45,000	$3,200 - $6,400
1,500 sq. ft.	45,000 - 68,000	$4,450 - $6,850
2,000 sq. ft.	60,000 - 90,000	$6,200 - $7,850
2,500 sq. ft.	75,000 - 113,000	$5,650 - $8,630
3,000 sq. ft.	90,000 - $135,000	$6,300 - $12,000

New Boiler System Cost by Fuel Type

Even though most householders rely on gas or propane boilers, some still use oil. If you consider switching to another fuel type, the process can be straightforward between the first two. Oil-to-gas conversion can be trickier and more expensive, but overall heating costs can decline with the new system. Residents of warm states can do well with electrical boilers, as high capacity is not the top priority. So, how much is a new boiler, depending on the fuel type? Let’s view this question in detail. 

Electric 

Replacing an electric boiler can run from $1,760 to $7,900, with the price of the unit alone ranging from $900 to $5,900. If your setup requires an electric panel upgrade to handle a high-powered boiler, your outlay can escalate by $1,340 to $2,780. Whether as the main heat source in regions with short winters or a supplementary one in cold regions, an electrical boiler can be the best bet. Plus, you won’t have to go all out with maintenance and installation. High operational costs can make for the biggest drawback. 

Oil

Oil boiler replacement costs range from $4,760 to $9,200, and the unit alone can set you back from $1,650 to $6,900. Even though oil boilers stand out with high heating efficiency and can warm up your home better than their gas counterparts, their maintenance can become a headache. Please note that many early models are no longer available on the market, so you may face some installation challenges. 

Gas

Gas boiler replacement costs from $4,000 to $11,000 installed. The unit’s price falls between $1,480 and $5,800, depending on the dimensions and brand. Its operation principle is similar to that of a furnace—a boiler maintains a set temperature within the home by burning gas. Hence, the unit requires a connection to existing natural gas lines, along with proper venting and a drainage system for condensation.

Propane 

You can shell out from $3,600 to $10,600 to replace a propane boiler, and the unit alone can run from $2,780 to $6,000. If you fall for propane high efficiency during combustion and potential cost savings, you can convert your gas boiler into a propane-fueled one for $200 to $580. Plus, you may need to invest in a propane tank or piping for the system. Nevertheless, such boilers are environmentally friendly and cost-effective in the long-term perspective. 

The cost of a new boiler by fuel type

Fuel type	Average cost per unit	Average cost (installed)
Electric	$1,340 - $2,780	$1,760 - $7,900
Oil	$1,650 - $6,900	$4,760 - $9,200
Gas	$1,480 - $5,800	$4,000 - $11,000
Propane	$2,780 - $6,000	$3,600 - $10,600

Cost of Boiler Replacement by System Type

Boilers can serve a dual purpose: warming your house and facilitating water flow through the pipes. However, some models are designed exclusively for heating. If you want the units to manage heating and water supply, you need to zero in on options incorporating dual tanks. The modern market offers various system types to choose from. Your choice can significantly affect the new boiler cost. 

Conventional 

The cost of traditional boiler replacement lands between $2,230 and $7,100. Such models boast a high energy efficiency rating of up to 90%, so hot water won’t come long after the tap is opened. If you own a spacious house and consider installing an underfloor heating system, this boiler type can be the best choice. 

Combi 

The combi boiler installation costs $6,100 to $10,300, with the unit running between $1,750 and $3,500. The combination boiler merges the home heating and on-demand hot water systems into one unit, offering a practical, space-efficient solution that quickly warms medium-sized or smaller homes. However, extra piping and connections make installing it more complex and expensive.

High-Efficiency

Installation costs for high-performing units range from $3,560 to $12,000. They can reach up to 98% efficiency, resulting in up to 20% energy savings. These boilers incorporate top-notch technologies, like modulating burners and precision control systems, allowing for the effective reusing of heat. This system type can be the most beneficial in cooler climates where heat conservation is the prime concern. 

The cost of home boiler replacement by system type

System type	Average cost
Conventional	$2,230 - $7,100
Combi	$6,100 - $10,300
High-efficiency	$3,560 - $12,000

Cost to Replace a Boiler by Brand

Whether your boiler will cost $1,400 or $7,500 depends much on the brand under which umbrella it has been produced. Yes, navigating a myriad of boiler names on the market can be tricky and exhausting. You can check in with your contractor for suggestions, as they can help you compare brands and price points to ensure you don’t compromise on quality.

Securing Permits

Permits are a prerequisite for boiler installation, which can cost between $50 and $330. The exact amount depends primarily on your home location and whether it’s replacement or installation from scratch, with the latter often falling on the higher side of this spectrum. 

Electrical Upgrades

If you have an inadequate electrical system at home, you should rewire a house and get a new circuit breaker box, which can cost you $2,650. Upgrading the amp service can add $1,400 to the outlay. 

Gas Line Installation

If you need an additional gas line, their installation cost can land between $30 and $75 per linear foot, with price gaps based on the type of pipe material used and assessment. The initial connection of gas lines can reach up to $2,000, excluding the hookup costs. 

Boiler Maintenance 

Scheduling boiler maintenance can cost between $76 and $127 per hour. These services generally involve a thorough inspection of the boiler, cleaning, and minor repairs as necessary.

Wrapping Things Up

Increased energy costs and frequent boiler breakdowns can make maintaining an old unit more expensive than installing a new one. Once you notice uneven heating, with some rooms feeling colder than others, weird noises, or signs of carbon monoxide leaks, you can’t delay boiler replacement any longer, as your safety becomes a concern. If you plan to move out and sell your property, a boiler upgrade can increase your home’s value and appeal. Buyers are more interested in homes with a reliable and efficient heating system.
