Total Energy Services service, install and repair all types of oil boiler

We are oil boiler specialists working on oil boilers across Dorset and surrounding counties.

Modern a rated condensing oil boilers are much more energy efficient than traditional models, many new models reach efficiency levels of over 95% whereas older models may not even reach an efficiency of 50% meaning half the money you spend on fuel is not actually going towards heating your home.

Total Energy always recommend a professional and qualified surveyor attends your home to ensure you purchase the right boiler for your home.

Similar to gas boilers there are 3 types of oil boilers as well, the 3 main types are;

  • Oil Combi Boiler
  • Oil System Boiler
  • Oil Regular Boiler

Oil Combi Boiler

Around 50% of new oil boiler installs are combi boilers.  They are nice and compact plus there is no need for a cylinder as water is taken directly from the mains.

Therefore, with an oil combi boiler you can take advantage of heating and hot water on demand, there compact design means some can even fit within a standard kitchen cupboard which is great if you would like to free up space within your home.

If you are replacing an older oil combi boiler for new oil combi boiler the installation tends to be easier and quick to install. Oil combi boilers also come with user friendly controls.

The big difference from oil combi boiler and gas combi boiler is that an oil tank is still needed to provide the fuel.  The oil tank can be above or below ground connected to your boiler by pipework.

Oil System Boiler

Oil system boilers are also a popular choice, like the gas system boiler the main boiler components are within the boiler meaning you do not need water tanks. You will still need a hot water cylinder which stores hot water for when you need it. This means that you can take advantage of instant hot water, however if the tank has run low you may need to wait for the water to re fill and heat back up.

System boilers are good for those who perhaps already have a oil system boiler and do not want to spend additional funds converting oil boiler type.

Regular Oil Boiler / Conventional Oil Boiler

Regular oil boilers are commonly found in larger properties, or older properties that may not have a high flow pressure from the mains water. They can also be popular with modern homes which have a large amount of bedrooms and bathrooms where the demand for hot water in high.

Like system oil boilers regular oil boilers also require a hot water cylinder to store hot water. They also need a cold water tank and tank which balances the water going into the cold water tank.
