System Boilers

  • How do system boilers function?

    Firstly, a heat exchanger heats the water. Then it moves energy from the gas jets to the water. Once the water is heated, it is moved to the hot water cylinder where it will be stored. Even when you are using multiple taps and showers, a constant supply of hot water is always available.

  • How much space is required for a system boiler?

    There are many things to consider but one of the most crucial points is how much space do you need for a system boiler. In general, a system boiler is larger than a regular boiler so you need to make sure that you have sufficient space. What makes a system boiler bigger is the fact that it has a pump and an expansion tank. It’s worth mentioning that the additional parts would be covered by the manufacturer warranty. An airing cupboard is where the hot water cylinder most likely to be installed.

    System boilers are perfect for homes with limited space because they do not need a header tank.

  • The efficiency of system boilers

    Due to the use of condensing technology, system boilers are very efficient. They can achieve up to 90% efficiency in ideal conditions. Taps and showers receive immediate hot water at the same pressure. As a result, they can also improve water consumption in your home.

  • Do system boilers run out of hot water?

    This factor is determined by the capacity of your hot water cylinder. You should consider how much water you need for taps, baths and showers when choosing the right size. However, you should keep in mind that the size of your cylinder will rely on the space available. A system engineer will help you design the hot water tank and the system to your ultimate satisfaction and your hot water demand. If calculated correctly, you wouldn’t run out of hot water.

  • How do system boilers supply hot water?

    A system boiler works together with a hot water cylinder to provide central heating and hot water to our homes. The boiler heats water directly from the mains to warm up our radiators, and fills the cylinder with boiling water that's used for our sinks, showers and more.
