High Efficiency Oil Boiler Prices in 2023 | The Definitive Guide

Reading Volume:

Generally, a high efficiency oil boiler can cost between $2,500 and $8,000, with installation costs ranging from $500 to $1,500. High efficiency oil boilers becoming the most popular choice for domestic and commercial heating. They are competitively priced, quiet, easy to use, clean, and operate by burning fuel oil.



What is a high efficiency oil boiler?

A high efficiency oil boiler is a heating system that uses oil as a fuel source to heat water or air for a home or building. The term “high efficiency” refers to boilers that are designed to convert a higher percentage of the fuel they consume into usable heat.

Compared to older, less efficient boilers, high efficiency oil boilers can save you money on their heating bills and reduce their carbon footprint. They typically have an efficiency rating of 85% or higher, which means that they convert at least 85% of the fuel they consume into heat, whereas older boilers may have efficiency ratings as low as 60%.

High efficiency oil boilers are typically condensing boilers, which means they are designed to capture and reuse heat that would otherwise be lost through the flue. They may also have advanced features such as electronic controls and variable-speed pumps, which can help to further optimize their performance.


High efficiency oil boiler vs standard

High efficiency oil boilers are designed to be more efficient and use less energy than standard oil boilers. This is achieved through a number of features such as improved insulation, more efficient combustion systems, and better control of the heating process. Some of the benefits of high efficiency oil boilers compared to standard oil boilers include:

  • Lower fuel consumption: High efficiency oil boilers use less fuel to heat your home, which means you save money on your energy bills.
  • Reduced emissions: High-efficiency oil boilers produce less carbon dioxide and other harmful emissions compared to standard oil boilers, which is better for the environment.
  • Better heat distribution: High-efficiency oil boilers distribute heat more evenly throughout your home, which means you get more consistent temperatures and greater comfort.
  • Longer lifespan: High efficiency oil boilers are built to last longer than standard oil boilers, which means you will need to replace them less often.

Overall, choosing a high efficiency oil boiler over a standard oil boiler can be a smart investment in terms of both energy savings and environmental impact. However, it’s important to consider the upfront cost of a high efficiency oil boiler, which may be higher than a standard oil boiler. You should also consider the availability of oil in your area, as well as the cost of oil compared to other heating fuels.

High efficiency oil boiler vs propane boiler

The choice between a high-efficiency oil boiler and a propane boiler largely depends on factors such as fuel availability, efficiency, cost, and environmental impact.

When comparing the two, there are several factors to take into account.

  • Fuel availability: The availability and cost of heating oil and propane may vary depending on your location. In some areas, heating oil may be more readily available and less expensive, while in others, propane may be the more practical choice.
  • Efficiency: Both high-efficiency oil boilers and propane boilers can be highly efficient. The efficiency of an oil boiler can range from 85% to 95%, while the efficiency of a propane boiler can range from 90% to 98%. It’s important to choose a model that is ENERGY STAR® certified to ensure maximum efficiency.
  • Cost: The cost of a high-efficiency oil boiler can be slightly less expensive than a propane boiler, but this depends on various factors such as fuel prices, installation costs, and maintenance costs.
  • Environmental impact: Both oil and propane are fossil fuels, so they can contribute to greenhouse gas emissions. However, propane is considered to be a cleaner burning fuel compared to oil. Propane also has lower emissions of nitrogen oxides, sulfur dioxide, and particulate matter.
  • Maintenance: Both oil and propane boilers require regular maintenance to ensure efficient operation. However, oil boilers may require more maintenance because they generate soot and carbon buildup, which can impact efficiency.

What is the level of increased efficiency offered by a new oil boiler?

Highest efficiency oil boiler

The efficiency of a new oil boiler will depend on a number of factors, including its design, size, and features. However, in general, new oil boilers are significantly more efficient than older models.

The efficiency of a boiler is typically measured by its Annual Fuel Utilization Efficiency (AFUE), which is a percentage that represents the amount of heat produced by the boiler compared to the amount of fuel consumed over the course of a year. Older oil boilers typically have AFUE ratings between 56% and 70%, while newer, more efficient models can have AFUE ratings of 85% or higher.

This means that a new oil boiler can be up to 30% more efficient than an older model, which can translate into significant savings on heating costs over time. However, it’s important to note that the exact efficiency gains will depend on a variety of factors, including the age and condition of the old boiler, the size and layout of the home, and the climate in the region where the boiler is being used.

How much does a high efficiency oil boiler cost?

High efficiency oil boiler prices

The cost of a high efficiency oil boiler can vary depending on several factors such as the brand, model, size, and features. Generally, a high efficiency oil boiler can cost between $2,500 and $8,000, with installation costs ranging from $500 to $1,500.

Other factors that can affect the cost include the complexity of the installation, the type of fuel line needed, and the cost of permits and inspections. Additionally, if you need to have an old boiler removed before installing a new one, there may be additional costs associated with that process.

It’s important to note that while a high efficiency oil boiler may have a higher upfront cost than a less efficient boiler, it can save you money in the long run through lower fuel bills and reduced maintenance costs.


In conclusion, high efficiency oil boilers are a great investment for you who want to save money on their heating bills. They’re easy to install, require minimal maintenance, and will last for years without needing any repairs or replacement parts.
