boiler replacement

If your existing boiler is not working as efficiently as it was when you first bought it, it might be time to invest in getting a new boiler installed for your home. Now, boiler replacement costs can be a big factor while making a decision to go through this entire process and this article aims to help you understand all the nuances of the associated costs – from boiler installation cost to the new boiler cost (product price).

Estimating the total boiler replacement cost

To understand the cost of getting your existing boiler replaced with a new boiler which is more energy efficient and cost-effective, we’re dividing the explanation into two parts – the equipment cost and the replacement cost. Let’s look at them in detail:

Understanding the Equipment Cost

The primary factor impacting the equipment cost is the type of boiler selected. The three most common kinds of boilers are:

Combination boiler

Combination boilers, which can heat both hot air in the building and the water for use in plumbing, are becoming more and more common. The efficiency of a combination boiler system lies in the fact that it can heat water on demand without a dedicated hot water tank, which frees up valuable floor space and may even cut down on energy losses caused by storing water in a tank. However, due to their sophisticated design and enhanced ability to manage several heating demands at once, these systems typically come with greater initial boiler installation costs.

Regular Boilers

These systems, which are also called traditional boilers, need an additional cylinder to store hot water. In houses with more than one bathroom, when hot water is required for numerous purposes at once, they are usually the best option. While the cost of the boiler unit itself may be less than that of a combi boiler, the installation of a more standard or conventional boiler itself is typically more expensive due to the necessity of supplementary components such as a cold water storage tank.

System boilers

System boilers are similar to traditional boilers in that they store hot water in a cylinder; however, unlike conventional residential boilers, system boilers include the majority of their essential components into the boiler itself, simplifying installation. They provide a more affordable alternative to conventional boilers while still providing some of the same benefits and being easier to install.

The annual fuel utilization efficiency (AFUE), reliability, customer service, and warranty terms offered by various companies can vary widely. The reputation for premium brands to last a long time and require less maintenance over time may cause them to attract a higher price. Although lesser-known companies may have more affordable prices, you shouldn't expect the same level of quality assurance or after-sales service.

Different types or series of boilers from the same brand usually have varying capacities and features. More sophisticated features, higher-quality materials, and more efficiency are typical in more expensive models. Though initially more expensive, these models usually end up saving money in the end because of their increased longevity and efficiency.

An important component of understanding boiler prices is its capacity, which is generally expressed in kilowatts (kW) or British Thermal Units (BTUs). A property's heating and hot water needs, as well as its size, dictate the required capacity. Boilers with more capacity are usually more expensive, but they are necessary for larger homes with considerable heating needs. Choosing the correct size is essential for effective functioning and to avoid spending too much on a unit with too much power.

Boilers nowadays often come equipped with a plethora of features meant to improve both their performance and the way they are used. Better energy management and lower heating costs and energy bills are possible with features like digital controls, weather compensation, and programmable timers. These features may be more expensive, but they are worth it for the ease and control they bring to energy management.

The introduction of modern technology has revolutionized the way boilers function. One recent innovation that has allowed for unprecedented control over heating systems is the smart thermostat, which can be adjusted remotely using a smartphone or tablet.

One way to lessen reliance on conventional fuels wood boilers is to use one of the many new boilers that are solar thermal energy compatible. Boilers equipped with these technologies may cost more upfront, but they can significantly reduce energy costs and make indoor climate control much more pleasant.

Replacement Costs for Boiler Installation

When budgeting for a boiler replacement, it’s important to include not only the cost of the boiler but also all the associated expenditures for installation, maintenance, and potential repairs. Let’s take a closer look at these expenses:

The final cost for a residential boiler replacement could vary greatly depending on the installation company you choose. The size and reputation of the company have a significant impact on the costs:

Individual Installers:

Installations done by a single contractor can often be more affordable. Nevertheless, the installation's timeliness and dependability may be impacted by their restricted availability and resources.

Medium-Sized Companies:

In most cases, these businesses offer a solid combination of price and quality. While they may not charge as much as huge corporations, their size allows them to respond to emergencies more quickly and provide better service overall than solo professionals.

Large Companies:

Large installation businesses typically charge more because they provide more features and a longer warranty on their services. With such rates, you have the guarantee of a dependable brand, extensive customer service, and, in many cases, a national presence.

The efficiency and longevity of the boiler are greatly affected by the installation company's level of experience:

Experience Level:

Companies that have been in business for a long time and have a solid reputation usually charge more. But with their knowledge, you can have a more dependable installation—and maybe avoid costly repairs and lost efficiency—in the long run.

Quality of Installation:

The efficiency rating of the boiler depends on its correct installation. Professional installers are more likely to maximize the boiler's efficiency and adhere to all local rules during the installation process.

Another factor that could impact the replacement cost is the warranty and service agreements that are provided:

Standard Warranty:

Boilers typically have a manufacturer's warranty that covers the unit's parts and, in some cases, labor for a specific amount of time. There may be an option to purchase an extended warranty for an additional cost.

Service Contracts:

To make sure the boiler performs properly and lasts a long time, some businesses provide service contracts that include maintenance checkups. While these contracts do increase the initial cost paid, they may end up saving money and easing concerns in the long run.

The cost might be affected by the timing of the boiler installation because of seasonal demand:

Off-Peak Discounts:

During the spring and summer, when heating system demand is lower, it may be more cost-effective to install a boiler. In order to maintain employee interest, certain companies may provide discounts.

Urgent Installation:

Due to increased demand and the perceived urgency of the situation, the cost of replacing a boiler or replacement during the winter or in an emergency situation can be greater.

The overall cost of the new boiler installation might be impacted by a number of other factors:

Removal of Old Boiler:

Costs associated with removing and disposing of an old boiler can range widely, particularly if the boiler includes asbestos or other potentially dangerous elements that necessitate specific handling procedures.

Alterations and Upgrades:

Changes to the current heating system, such as improvements to gas lines, flues, or venting systems, may be necessary for installation, which might increase the cost.

Rules and Regulations:

Extra effort and resources may be needed to make sure the installation follows all applicable rules and regulations, such as those pertaining to energy efficiency or local building codes.

Physical Accessibility:

If the installation site is inconveniently located, such as a basement or a high-rise building, the labor expenses may be higher than expected.


The expense might go up due to the extra labor and parts needed for custom boiler installations that demand one-of-a-kind setups or connections with preexisting HVAC systems.

I had an issue with my furnace, went to reset my main breaker to power cycle trying to troubleshoot it... Breaker crapped out so I was sitting on an electrical, and furnace problem.Gave these guys a call and they were able to come out within 2 hours. Required a full main breaker replacement, and new gas valve on my furnace. They diagnosed it in only a couple hours, and fixed everything the same day.Had a great experience, the technicians that showed up were professional, and very knowledgeable. I'll definitely be using these guys when I eventually have replace my aging furnace.
