Combi boilers heat your home and your hot water in one unit, removing the need for water tanks.
A system boiler requires a hot water cylinder and can provide high hot water flow rates but can run out of water.
Conventional boilers require multiple tanks as they don’t use the water mains for pressure.
New boilers can either be the same or a different type. In general, keeping the same type of boiler is the simplest boiler installation. Changing the type of boiler will increase your new boiler quote because the work is more complicated and longer pipework will be required.
