best condensing oil boiler


Condensing oil boilers are a relatively new technology in the world of oil heating. They offer many advantages over traditional boilers, including lower running costs and greater reliability. But before you decide to buy one, it is important that you understand what a condensing boiler is and how it works.

What is a condensing oil boiler?

condensing oil boiler

A condensing oil boiler is the same as a normal oil boiler, except that it does not release the flue gases into the atmosphere. Instead, it cools them to their dew point and then returns them to their liquid form. This process reduces energy consumption by up to 50% compared to non-condensing boilers.

However, condensing boilers are more expensive than non-condensing boilers due to the additional components required for this process (such as a pressure gauge).

Are condensing oil boilers any good?

Are condensing oil boilers any good?

The answer is yes, but not necessarily for the reasons you might think.

If you’re unfamiliar with the concept of condensing boilers, they are exactly what they sound like: boilers that turn off the heat source when water reaches its boiling point. Instead of emitting water vapor into the atmosphere as steam and waste energy as heat, condensing boilers recapture those emissions and convert them back into usable energy (in this case, hot water). This can result in up to 92% efficiency on your part (compared to around 80% for conventional boilers), which means less fuel purchased over time for heating needs or cost savings through lower electricity bills if you use natural gas instead.

But why would anyone want a more expensive boiler? The benefits go beyond simply saving money on buying less fuel—they also reduce stress on our environment by cutting back on greenhouse gas emissions; add years onto your home’s lifespan by reducing wear-and-tear caused by corrosion; and make it easier than ever before to keep track of how much energy your home consumes throughout each day/week/month via remote monitoring tools such as Nest Learning Thermostat™ right from your phone or computer! And since these systems require less maintenance than other types (such as oil-fired burners), there’s no need worry about regular service calls either.

What are the disadvantages of a condensing boiler?

condensing boiler disadvantages

The disadvantages of a condensing boiler are:

  • More maintenance is required. Because the system is more complex, there are more parts that can break down and require repair or replacement.
  • It’s more expensive to install. The cost of installing a condensing boiler can be significantly higher than installing an ordinary boiler because it requires extra ductwork and other fittings in order to introduce heat exchangers into your home’s heating system (see diagrams).
  • It costs more to run. Running a condensing boiler means you’ll be using less energy with each kilowatt/hour of heat generated by your fuel source—which also means spending less money over time on gas or electricity used for heating purposes; however, this benefit is often offset by the high price tag associated with installing such systems ($10k-$20k).
  • Maintenance costs will be higher than those associated with traditional models due largely because there are so many parts involved in operating such units properly (elements like pumps) which require regular checking & cleaning out before long periods without use lead them failing altogether due corrosion buildup within their chambers etcetera…

Are condensing oil boilers cheaper to run?

condensing oil boilers run cost

When it comes to boilers, the more efficient the boiler, the cheaper it is to run.

The efficiency of your oil boiler will be shown in its Annual Fuel Utilisation Efficiency (AFUE) rating. The higher this rating is, the less fuel you will use and therefore cost per year.

For example:

  • If you have a 60% rated condensing oil boiler that uses 5 litres of fuel per hour (lph) then it will use 30kWh/hour when running at full power.
  • If you have a 90% rated non-condensing oil boiler that uses 10 lph then it would use 60kWh/hour when running at full power

What is the most efficient oil boiler?

The most efficient oil boiler is the condensing oil boiler. This means that it has a heat recovery system that uses heat to produce hot water, which can be used for heating and hot water needs. In comparison with other boilers, this one will use up to 90% less fuel for heating because of its efficiency. However, condensing boilers are also more expensive and take up more space in your house or apartment.

This type of boiler works by taking out moisture from the exhaust steam through an internal coil or pipe made out of copper or stainless steel; instead of releasing this gas into the atmosphere as usual (which would contribute to greenhouse gases), it sends it back into the combustion chamber so that it can mix with air again before being released as exhaust gases via an outlet at the top of your home’s roofline. You won’t see any noticeable difference between emissions when using this kind versus another style either—which means no higher electric bills due solely on fuel usage!

Condensing oil boilers are more efficient than regular oil boilers. This is because they recycle the heat that is normally lost up the chimney, making them more efficient in terms of fuel use and the amount of heat produced. They also have a higher thermal efficiency (or lower burner consumption) because more of their heat energy goes into heating your home instead of being lost up the chimney, and they have a higher heat transfer coefficient (due to better insulation) which means they don’t need as much ventilation or cooling to operate safely.

How much does it cost to install a oil boiler?

oil boiler install cost

A well-trained technician can install your oil boiler in a matter of hours. The average cost of installing an oil boiler is between £1,000 and £2,000. The price will depend on the size of your home and whether you do any part of the installation yourself (you can save money if you do).

You should also factor in the cost of maintenance when choosing an oil boiler system for your home. In most cases, homeowners pay only once every five years to have their system serviced by a professional—but this depends greatly upon how much use they get out of their heating system during those five years.

What type of oil burner has the greatest operating efficiency?

Oil burners are the most efficient heating units on the market. This is particularly true of oil boilers, which use hot water to produce domestic hot water, space heat and sometimes even air conditioning. They are more efficient than gas-fired boilers because oil is a higher quality fuel than natural gas and produces less CO2 per unit of heat generated compared with natural gas or propane. They also tend to be more efficient than oil burning furnaces because they allow for greater control over combustion conditions within the system’s burner. They’re also more efficient than wood burners since they don’t require constant feeding during operation (as long as you store your fuel outside). If you’re interested in reducing energy consumption and lowering utility bills while still maintaining control over how much warmth enters your home through various systems such as radiant floors or baseboard heaters, an oil boiler may be right for you!


The most efficient type of oil boiler is a condensing oil boiler. They are more expensive to buy than standard boilers but they will cost you less to run over the lifetime of your boiler. They also have many other benefits including being quieter, cleaner and safer than older models.
