System boilers store hot water, in a storage tank usually located in the loft. This allows you to run more than one hot water tap at a time without risking any loss in water pressure. This is unlike the combi boiler that heats water on demand but you may notice a loss in pressure. The advantage of the combi boiler is that there is no need to take up space with a storage tank. Which system you use depends on your house, and hot water usage habits. Our engineers will help you decide if you’re not yet sure, or think a different system to your current one may suit your lifestyle needs better.
