A conventional boiler requires a storage tank/water cylinder in which the hot water is stored. The system can be enabled and disabled so that you can produce hot water only when required.

Advantages: Much better suited to large households in which multiple persons will need hot water simultaneously.

Disadvantages: Once the hot water is depleted from the tank/storage system you’ll be required to wait.

Boiler Efficiency: Gas central heating furnished by your boiler will account for 60-70% of your home emissions. Choosing the right efficiency is key to reducing your energy bills and lowering your footprint on the atmosphere.
