What are condensing oil boilers?

Condensing oil boilers use oil as a fuel source. They are called “condensing” because they are designed to capture and reuse the heat that would normally be lost during the combustion process.

This makes them much more efficient than non-condensing boilers, which waste a lot of heat energy.

Because of their fuel efficiency home and business owners have continued to turn to condensing oil boilers for their heating needs.

How do Condensing Oil Boilers work?

Condensing oil boilers work by burning oil to heat water, which is then circulated through radiators or underfloor heating systems to provide warmth to your home.

The combustion process produces waste gases, which are expelled through a flue. In a non-condensing boiler, these gases would be vented out into the atmosphere without being reused.

However, in a condensing boiler, the waste gases are directed through a heat exchanger, which extracts heat from them before they are expelled.

The heat exchanger in a condensing boiler is designed to cool the waste gases to a temperature at which they condense into a liquid. This process releases additional heat energy, which is then reused to heat the water in the boiler. The condensed water is then drained away through a pipe.

Why are they good for homes and businesses?

There are several reasons why condensing oil boilers are a great choice for homes and businesses.

First and foremost, they are much more efficient than non-condensing boilers. This means that they use less fuel to produce the same amount of heat, which can result in significant cost savings for you.

In addition, because they reuse waste heat energy, they are much more environmentally friendly than non-condensing boilers.

Condensing oil boilers are also very reliable and require minimal maintenance. Because they are designed to capture and reuse waste heat energy, they operate at lower temperatures than non-condensing boilers, which reduces wear and tear on the system.

This means that they are less likely to break down or require repairs, which can save you money on maintenance costs.

Finally, condensing oil boilers are very versatile and can be used in a wide range of applications. They are suitable for both homes and businesses and can be used to heat large or small spaces. They are also compatible with a variety of heating systems, including radiators and underfloor heating.
