It is important to note that purchasing a system boiler, that you will need space in your home for an additional hot water cylinder. This is where your hot water will be stored once heated. For this reason, a system boiler is not recommended for homes with limited space. However, if space is not an issue in your home, a system boiler is perfect for properties with a high demand for instant hot water.
