Oil Boilers

Oil Boilers

Many people think that oil boilers are not going to be energy efficient and they are wrong! Combination or combi (shorthand) oil boilers are actually very energy efficient because they adopt new boiler technology. Combination boilers allow for greater control and lose less heat and are more efficient at heating your home and could save you money down the line. If you are concerned that oil is not a renewable resource you may choose another type of combi boiler that T&S provide and you can learn about all of them on our website. However this page will explain all about oil boilers and how they can heat your home efficiently and tell you all about them to see if it is the choice for you.

T&S heating provide all types of boilers and we understand that certain facilities such as gas lines are not available in some areas; for example in the country side or other potential areas where there is not a gas mains then you have an alternative option. Combination oil boilers are easy to fit and they don’t take up much room, they are in fact energy efficient however T&S only recommend this option if mains gas is not available. That is because gas combination boilers are cheaper and has less carbon emissions, however if said facilities such as mains gas are not available then you have the oil boilers as a substitute. They still are energy efficient and far better than previously old technology boilers.

The reason why combination boilers are so efficient at saving energy is because you have ultimate control and only heats the water when it is needed rather than heating water that will lose heat eventually.

There are also other reasons why combination oil boilers are viable, combination boilers whether they are oil, gas or LPG are very small making them easy to fit almost anywhere in the home. Also as they heat the water on demand they don’t need a tank to store the hot water in. Therefor it takes up a lot less space, normally you can just fit it to an existing system with a few modifications of course and you will be up and running in no time. However as said before if you have the gas mains facility T&S recommend it but the combi oil boiler is available if not and still does a fantastic job of heating your home and water supply cheaply and safely.

How does the oil boiler work internally

Most oil boilers use a fuel called kerosene. The reason for using kerosene is because it burns cleanly unlike other heavier fuels such as gas oil that doesn’t burn so cleanly. As the amount of sulphur in the fuel has dropped as some domestic suppliers have added some lubricants to make it easier to be pumped to the boiler. This is sometimes not necessary as they have engineered pumps to work with low sulphur fuel but you can ask a T&S engineer for advice. So, the real question that will obviously come up is, “Will a combination oil boiler be effective and still be energy efficient at heating my home?” The answer is an emphatic, ‘Yes!’ as they are engineered to burn fuel properly and transfer heat on demand. Gas is better on carbon emissions and can be cheaper but of course that facility may not be available.

Pros and cons of an oil boiler

So finally to sum up everything we will show all the pros and cons of an oil boiler so you can decide if you want it. Also don’t forget T&S offer free impartial advice when it comes to requesting a quote so you don’t have to make up your mind on your own. Here are the pros points of an oil boiler:

  • Because it is a type of combination boiler it is small and can be fitter almost anywhere in the house.
  • As the oil boiler is a combination boiler type it saves you money and transfers heat efficiently.
  • It burns the fuel cleanly and is a great solution for those in the countryside that care about the environment.

Here are some of the cons of an oil boiler:

  • Oil combination boilers are less energy efficient than a gas combi boiler.
  • Oil is generally more expensive than gas on the mains.
