What are the Advantages of System Boilers?

Abundant Hot Water Supply: System boilers typically offer a generous supply of hot water, making them ideal for households with simultaneous usage of multiple taps, showers, and radiators.

Solar Energy Compatibility: By connecting the appropriate cylinder, system boilers can harness solar energy, offering an environmentally friendly and cost-effective heating solution.

Space Efficiency: System boilers require less space than regular boilers, as they do not necessitate an expansion tank or external expansion vessels, simplifying installation and saving space.

Economical and Fast Operation: Equipped with a pump, system boilers respond quickly and boast more economical running costs compared to other boiler types.

    Important Considerations for System Boilers:

    While system boilers offer numerous benefits, it’s essential to be aware of potential drawbacks:

    Space Requirement: Although smaller than regular boilers, system boilers still occupy more space than combi boilers due to the external cylinder, posing challenges for installation in smaller homes.

    Limited Hot Water Supply During Peak Times: Despite ample hot water storage, system boilers may struggle to meet increased demand during busy periods, resulting in the need to wait for the cylinder to reheat, typically taking 30-40 minutes.

        FAQs

        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 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 is most likely to be installed.System boilers are perfect for homes with limited space because they do not need a header tank.

        How do system boilers work?

        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 often a Worcester Bosch boiler needs to be serviced?

        It is recommended that you service your Bosch boiler yearly to help ensure that your boiler is running as efficiently and safely as possible.

        What is the difference between Worcester Bosch 4000 and 8000?

        The key difference between the two models is the availability of power outputs. The 8000 is more powerful and made for larger homes that have a higher demand for heating and hot water.
