Oil Boilers Guide: Oil Fired Condensing Boilers

The oil fired condensing boilers are still an essential piece of equipment for many homeowners in the world (or at least until their oil boiler eventually breaks down and stops working!) There has been a lot of speculation as to whether oil-fired boilers will be phased out in favor of more cost-effective and eco-friendly solutions. After all, there are alternatives such as gas or renewable energy sources.

An oil fired condensing boiler is a type of steam boiler that uses oil as its primary fuel. It’s also sometimes referred to as an oil-fired, direct-fired, or single-effect steam generator. These boilers are typically smaller than conventional steam boilers and have limited recovery rates which means they’re not very efficient at producing large amounts of heat. However, if you only need to generate small amounts of heat in your home or office then this may be the right choice for you!

The main advantage of owning an oil fired condensing boiler is that it’s much more eco-friendly than other types of heating systems because it doesn’t produce harmful emissions into the atmosphere as coal-fired boilers do. The downside is that these are usually less efficient than other options out there so make sure before making any decisions about your next purchase!

What are condensing boilers?

Oil fired condensing boilers

Condensing boilers work by recovering heat from flue gases and transferring it to the water being used in your home. They’re more compact than standard boilers, which means they can be installed in smaller spaces. In addition to these benefits, condensing boilers are also more efficient than non-condensing boilers—they recover as much as 95 percent of the energy that would normally be wasted through the chimney.

The following is an example of how a condensing boiler works:

  • Water is fed into the unit and heats up inside your house.
  • As it passes through coils in an insulated casing (the “back box”), warm water vaporizes and rises up into exhaust ducts on top of your roof or side wall where it cools down back into liquid form again before leaving via exhaust flues directly above them inside your home’s chimney

How efficient are condensing oil boilers?

High-efficiency condensing oil boiler

When you’re purchasing a new boiler, it’s only natural to want the most efficient model. Condensing boilers are more efficient than standard boilers, which can often save you thousands of dollars on your next utility bill.

However, condensing boilers are also more efficient than gas boilers and oil boilers—and that’s where things get interesting. While electric boilers tend to be quite expensive upfront (but very cheap in terms of operation), they pay for themselves over time because they require no fuel and therefore have zero operating costs. But when it comes down to it, there’s no question that a properly-maintained condensing boiler will provide you with better performance and lower energy bills than any other type of heating system—it just depends on what kind of budget you’re working with!


Are oil-fired boilers to be phased out?

Oil boilers are on the way out. Electricity and gas have been getting cheaper over time, and oil has become more expensive. This means that it is not economically viable to use an oil boiler anymore. As a result, most homes are now using electricity or gas-powered boilers instead of oil-fired ones.

Oil fired condensing boilers were phased out in favor of electric and gas ones because:

  • Electric/Gas is cheaper than Oil
  • Electric/Gas produces fewer waste products (carbon dioxide) compared to Oil
  • Electric/Gas can be easily converted into renewable energy sources such as solar panels or biomass fuel pellets

Oil condensing boilers last on average 20-30 years. This is a long time, especially considering most boilers last between 10 and 15 years. Oil boilers are more expensive to run than gas burners; however, they are still cheaper than oil storage tanks which are not included in the price of an oil boiler (they must be rented separately).

Oil condensing boilers can cost anywhere from $2000 – $6000 depending on their size and brand name. This is quite a bit more expensive than gas-fired models that only cost around $1000 – $3000 dollars for similar-sized units (but remember: it’s still cheaper than renting).

The maintenance costs for an oil boiler are also higher than gas-fired models because you have to change your filters regularly as well as monitor other aspects of its operation such as pressure levels etc.



Condensing oil-fired boilers is an efficient alternative to the traditional types of boilers. They offer you a lower consumption and therefore a lower bill to pay. They can be installed by our Gas Safe registered fitters and they come with a warranty of up to 10 years, so you know that they will last for many years without any problems.
