How do the different oil boilers work?

The great thing about oil boilers is their versatility. Perhaps the biggest advantage of a traditional oil boiler is that it doesn’t need as much fuel to run, which means that your heating bills will be cheaper.

Oil combi boilers get around the space problem by being incredibly compact, but their big draw is that you get hot water on demand. They’re extremely efficient, and they can last for years with proper maintenance.

Finally, system boilers can store a larger amount of hot water than other types of boilers, and they’re compatible with solar thermal systems, which can help you save money on your energy bills. There’s also no need for a cold water tank, and they have faster heat-up times than many other boilers.
