For those who cannot get access to the mains gas supply, oil boilers are the preferred heating system to choose. All new oil boiler installations must be condensing as of April 2007.
The greatest advantage of condensing oil boilers is that they also convert more fuel into heat than non-condensing ones. So, if you have an old non-condensing oil boiler, now is the time to replace it.
Types of Oil Boilers
Similar to gas boilers, oil boilers also have 3 different types; combi, system and regular
Combi Oil Boilers
The most modern type of oil boiler is the combi boiler. They're smaller in size, cost-effective, and provide on-demand heating and hot water. That means no additional tanks or cylinders are required.
The combi boiler receives its water directly from the mains and heats it as required. So there's no need to wait for the cylinder to refill with warm water. After that, the water is carried from the boiler to the radiators and taps.
This can help you save a lot of money on your heating bills.
System Oil Boilers
Similar to combi boilers, system boilers get their water from the main supply, however, it stores the hot water in a cylinder for a couple of hours. This is ideal for homes with two or more bathrooms and has a high demand for hot water.
Regular Oil Boilers
They are the most common type of boiler in older properties. Even though they have been around for a while, they are more reliable and efficient than combi and system boilers. However, a regular oil boiler should only be considered as a direct replacement for an old regular oil boiler.
If you have a combi or system boiler, a normal boiler should be ruled out. This is because, in addition to the boiler, you'll need a hot water cylinder and tanks in the loft. To connect them all, a huge pipe network is required.
