What are the three main types of boiler systems?
What is a combi boiler?
A combi boiler, short for combination boiler, can either be electric or gas. This is the most common type of boiler as it has a simple design, requiring minimal space in your home as it does not need a water tank. It is easy to install and is very energy efficient, which could potentially save money in the long run. Its main benefit is that it provides instant hot water straight to your taps and radiators, making it more efficient and sustainable.
What is a heat only boiler?
A heat only boiler, also known as a regular or open vent boiler, heats up your home using a cold water tank, and a hot water cylinder as well as outside components such as feed and expansion tank in your loft. Water can sometimes be lost in the system through evaporation which is why a feed and expansion tanks will help maintain water pressure. They are a more conventional way of heating your home with cheaper installation cost. They are typically better in larger homes because they can supply hot water to multiple radiators or taps etc.
What is a system boiler?
A system boiler works with a hot water cylinder, and it is not open vented meaning there is no water tank, and certain components that are usually on the outside of the boiler, are on the inside. The benefits of a system boiler is that it can reach high hot water demand, for example, multiple showers or larger homes. However they do take up more space than a combi boiler. The hot water cylinder is normally sized to accommodate your typical usage, meaning if you are unexpectedly using a lot more hot water than usual, you may have to wait until the boiler can reheat the cylinder again as the cylinder volume can be depleted.
