As the names for these types of boilers suggest, external oil boilers are located outside of your home, whereas internal oil boilers are fitted inside. 

Internal oil boilers are installed like any other boiler - in a cupboard or utility room. Depending on whether you have a combi, system, or regular oil boiler, it can take up more or less space inside your home. Regardless of boiler type, internal oil boilers are still more compact than external ones. 

External oil boilers, on the other hand, are generally installed in a shed or garage and supply hot water to your home via additional pipework. This kind of oil boiler needs to be installed outside the home because it is generally larger and more powerful than internal oil boilers. 

When deciding which option is the best for your home, you will need to consider 2 main factors: cost and space. External oil boilers are both more expensive and take up more space (albeit outside of your home) due to their larger size. In comparison, internal oil boilers are more cost-effective. They are also compact, but they might still take up quite a bit of space if you require a system or regular boiler. 

In a smaller home, one thing that is greatly valued is space. As a result, the best kinds of boilers for this kind of living situation are combi boilers. They are compact and can easily tend to the energy consumption requirements of a smaller household.

For a better idea of what the best oil combi boiler for your home would be, you can check the combi boiler models we have listed above. In addition to the boiler model and manufacturer, you will also need to consider the power output you need.

Larger homes require greater power output from their boilers. In some cases, an oil combi boiler might be good for the job. However, they are generally not well suited for higher energy needs.

As a result, the best oil boiler for a large house would be either a system or a regular boiler, as they can easily attend to high energy consumption requirements. For a better idea of which regular or system oil boilers are the best in the UK today, you can consult the lists we have compiled above.

No clue which type of oil boiler would be best for your home? Not to worry. A heating expert can help you determine which oil boiler size or type you would need to make the most out of your home heating system.

To make the most of your home heating system, you will want to make sure that you install a highly efficient oil boiler. Boiler efficiency is a crucial factor to keep in mind when choosing your appliance, as it indicates how well fuel is converted into usable energy for your home.

Boiler efficiency is calculated as a percentage. Today, oil boilers have an efficiency rate of around 92–95%. This means that only 5-8% of the oil used to fuel your appliance is wasted in the process of being converted to energy, making them a highly-efficient home heating solution. 

In terms of the most efficient oil boiler models on the market, all the options we have mentioned above have high efficiency ratings. However, some of the oil boiler models that stand out are the Worcester Bosch Heatslave II and the Grant VortexPro with efficiency rates of as high as 95%. 

With efficient oil boilers such as these, you are guaranteed to enjoy the benefits of a quality oil boiler, as well as avoid overspending on your annual heating bills.

In terms of grants, you could apply for the ECO4 (Energy Company Obligation) Scheme if you live in England, Scotland, and Wales.
