How Much Does Boiler Installation Cost?

Boilers work by passing cold water through a series of heated pipes. Heat is then exchanged to warm the water, which is circulated around the home.

A new boiler installation cost can be complicated to determine because there are many different factors that go into purchasing and installing a gas boiler. Installation and maintenance is performed by some Plumbing companies and most HVAC companies — you might have to search reviews to see if they handle boilers.

Boilers do tend to undergo wear and tear over the years, requiring repair or replacement after a certain amount of time. Labor costs can also vary widely, from simple installation jobs of $100 to more complex installations costing up to $2,000.

There are different types of boilers that can be installed in the home, with each type working in a specific manner and having its own cost factors. Some of the most commonly used boiler types include:

For most average-sized homes, system boilers cost about $1,500 to purchase. They work by keeping high-pressure hot water in a sealed cylinder, where it can be dissipated to multiple taps within the home at the same time. This means that there is a minimal drop in water pressure regardless of the tap being used.

Standard boilers are made for larger residences and buildings. They work by keeping a storage tank of hot water that heats the pipes that ran through it. Water can thus be supplied via a series of taps as needed. They typically cost about $3,500.

The gas boiler installation cost will also depend on additional factors. For example, switching from an oil to a new gas boiler will involve an initial gas hookup cost of $750. The oil boiler will also need to be removed at a cost of $500-$3,000, and a chimney liner will need to be installed ($1,000).

A new boiler cost, including installation, averages $7,000 (but the cost can range between $4,000-$7,500).

Most homeowners struggle with repairing or replacing their gas boilers. When making this decision, important factors to consider include:

Lifespan: most boilers may need to be replaced after every 15 years - it may be better to purchase a new unit if older than 15 years.

Frequency of repairs: boilers that are frequently breaking down may lead to high repair costs. With average repairs costing between $400-$500, a boiler that requires frequent repairs is better of being replaced.

Water heating bills: it may be a good idea to consider boiler replacement in order to save in the long run.
