Oil Boiler Guide: Condensing Oil Boiler Prices

The price of a condensing oil boiler ranges from £2,500 to £10,000, depending on various factors such as the fuel, model, and manufacturer of the boiler. We are often asked about condensing oil boilers, and it’s no wonder – they’re all the rage nowadays! So we’ve decided to do some research and put together this guide for all of you who have been wondering how these units work, what they can be used for, how much they cost, etc. We think that once you read this article you will have a good idea of whether or not a condensing boiler is right for your home or business.

What are condensing oil boiler?

A condensing boiler is a system that heats water to create steam, which powers a turbine before the steam is cooled and condensed back into water. Condensing boilers produce low greenhouse emissions, as they don’t allow any of their byproducts to escape into the atmosphere.

This process requires a much higher fuel input than non-condensing boilers, but it also gives you an overall better efficiency than standard boilers—making these units particularly useful where there are high gas prices or limited space.

Condensing boiler technology is the latest face of boiler innovation, with typical efficiencies greater than 90% as opposed to the more regular 85% or so.Carrying extra heaters and returning them to a lower temperature, this makes them extremely efficient condensing boilers that also meet the Environmental Protection Agency’s definition of a condensing boiler.


Are condensing oil boilers any good?

If you’ve ever shopped for an oil-fired boiler, you may have come across the term “condensing” or “condensing boiler.” What does this mean and is it better than a conventional boiler? In short, yes.

Condensing boilers are more efficient, reliable and environmentally friendly than their conventional counterparts. Their efficiency is based on the fact that they remove excess moisture during operation by condensing it into water and then burning off this water in an auxiliary chamber. Without removing this excess moisture, boilers would use more fuel to heat up the same amount of water.

The reliability of a condensing oil boiler stems from its ability to produce less soot due to having cleaner burn gases overall—less soot means fewer problems with combustion performance (e.g., corrosion).

Additionally, because there’s less debris left over after combustion occurs within the furnace chamber itself (i.e., no ash), there will be less buildup inside of your flue pipes which could lead to blockages down farther along in those same pipes where they connect with chimneys or other airways coming out from under rooftops onto exterior walls; these blockages can lead back into rooms below where people might be sleeping so if one were ever struck by falling objects such as bricks/stones etcetera then these individuals would likely sustain serious injuries due.

How long do condensing oil boilers last?

If a condensing oil boiler is well maintained, it can last for up to 15 years. However, if you’re not keeping an eye on the system and making sure that everything’s in good working order then it could fail much sooner. If you notice any of these symptoms then chances are your boiler is due for replacement:

  • It’s noisy or vibrating when running
  • You have problems with the hot water flow rate
  • The heating and hot water systems don’t work properly together


How much is condensing oil boiler?

Condensing oil boilers cost more than non-condensing boilers. The price of a condensing boiler is more because it has more parts, and these parts are expensive. For example, the burner in a non-condensing boiler costs less than the burner in a condensing boiler because it doesn’t include an additional heat exchanger to capture the heat produced by burning gas or oil. Also, since there’s no need for extra piping to take that captured heat away from your home (into an outside drain), there’s less material used up overall compared with other models on the market today.

All told, this makes them much cheaper than their counterparts but still not as cheap as we’d like them to be!


Why is a condensing boiler more efficient?

The condenser unit is designed to transfer the heat from the flue gas into the water in your boiler. This is done by using a heat exchanger, which allows for very efficient use of energy. When you use an oil boiler that does not have a condensing option, it wastes much of its fuel because it only transfers heat once. With a condensing boiler, however, you can use almost 100% of your fuel’s potential energy!

Condensers also make your home quieter because they don’t require fans like traditional boilers do.

What size condensing boiler do I need?

This is an important question, and one that many people ask when trying to choose a new boiler for their home or business. The size of your boiler will be dependent on several factors such as:

  • The amount of hot water you need during peak times.
  • Whether you want to use your heating system in the summer months or not (heat pumps are more efficient when they can be used as heat sources).
  • How many radiators you have in your house or building.
