Condensing Oil Boiler Prices

Price: $3,200.00 - $16,500.00

A condensing oil boiler is a type of boiler that uses oil as its fuel. The oil is burned in a furnace to heat water, which is then sent to the radiators in your home. They are more efficient than traditional boilers because they use less fuel by recycling heat from their exhaust gases and condensing them into steam again.

What is a condensing oil boiler?

A condensing oil boiler is a type of boiler that uses oil as its fuel. The oil is burned in a furnace to heat water, which is then sent to the radiators in your home. Condensing boilers are more efficient than traditional boilers because they use less fuel by recycling heat from their exhaust gases and condensing them into steam again before sending them back out into your home’s heating system.

How does condensing oil boiler work?

The following is the working process of a condensing oil boiler.

  1. Oil is heated to high temperatures.
  2. The heat is transferred to the water.
  3. The water is heated to high temperatures, turning it into steam.
  4. Steam flows through pipes in your home and powers a turbine, which generates electricity that can be used for heating or cooling purposes.

Is a condensing oil boiler more efficient?

Yes. A condensing oil boiler is more efficient than a standard oil boiler because it has higher thermal efficiency and lower heat loss.

A typical condensing boiler will have an efficiency of at least 97%, which means that only 3% of the energy in the fuel is lost through heat loss to the atmosphere. This compares with around 80% for non-condensing boilers, meaning that you’ll save money on your heating bills as well as reduce CO2 emissions by up to 30%.

Pros & Cons.


  • Oil condensing boilers are the most efficient type of boiler, so you’ll use less energy than if you had another type.
  • You can get them in a range of sizes and outputs. You can even get them to suit your specific needs in terms of heating capacity, which makes them ideal for homes with larger rooms or multiple floors.
  • They’re also incredibly reliable–there’s almost no maintenance required on these systems because they’re designed to last for years with minimal upkeep needed along the way!


  • Oil-condensing boilers are more expensive than standard boilers.
  • The condensing process requires more maintenance and cleaning to keep the system working efficiently, which can be time-consuming.

How do you choose a condensing oil boiler?

Choosing the right condensing oil boiler can be a significant decision, and there are several factors to consider. Here are some of the key considerations when choosing it:

  1. Efficiency: One of the primary benefits of a condensing oil boiler is its efficiency. Look for a boiler with a high AFUE (Annual Fuel Utilization Efficiency) rating, as this indicates that it will convert a greater percentage of fuel into heat for your home.
  2. Size: The size of the boiler is also crucial. Choose a boiler that’s appropriately sized for your home, as a boiler that’s too small won’t heat your home effectively, and a boiler that’s too big will waste energy.
  3. Features: Consider what features you need from your boiler, such as a built-in timer or thermostat control, which can improve energy efficiency and help you save money on your heating bills.
  4. Brand and Warranty: Look for a reputable brand that offers a good warranty and after-sales support. This will give you peace of mind that your boiler will perform reliably and efficiently for years to come.
  5. Installation and Maintenance: Finally, consider the installation and maintenance requirements of the boiler. Ensure that the installation is carried out by a qualified professional and that ongoing maintenance is manageable and within your budget.

By considering these factors and consulting with a qualified heating engineer, you can choose a condensing oil boiler that’s right for your home and heating needs.

Are condensing oil boilers any good?

Yeah, condensing oil boilers are pretty good. They're efficient and cost-effective, so you'll save money on your energy bills. Plus, they produce fewer emissions than traditional boilers, which is better for the environment.

Why is a condensing oil boiler more efficient?

A condensing oil boiler is more efficient because it can reuse waste heat from the combustion process. Traditional boilers waste a lot of heat, but a condensing boiler can capture that energy and use it to heat your home or water.

What is the most efficient temperature for a condensing oil boiler?

The most efficient temperature for a condensing oil boiler is around 55°C. That's because it allows the boiler to operate at peak efficiency without wasting any energy. If the temperature is too low, the boiler won't be able to heat your home effectively.

What is the difference between a boiler and a condensing boiler?

The main difference between a boiler and a condensing boiler is that a condensing boiler is more efficient. It can capture waste heat from the combustion process, which means it uses less fuel and produces fewer emissions. Traditional boilers can't do that.

How much oil does a condensing boiler use per hour?

On average, a condensing oil boiler might use 3 to 5 liters of oil per hour, but that can vary depending on your specific situation. The amount of oil a condensing boiler uses per hour depends on the size of the boiler and how much you use it.
