How will I know if this Boiler is Suitable for My Home?
System boilers, like the Vokera evolve S, take water directly from the mains and require a separate cylinder for storing hot water. That means they need a bit more space than combi boilers but less space than regular boilers. The evolve S from Vokera is ideal for homes with limited loft space and a high demand for hot water.
You must pick a boiler that can meet the heating and hot water demands within your home, so we recommend you contact a Gas Safe registered engineer who can help you select the correct boiler type and size for your needs.
