This type of system is more traditional and is normally found in older houses. They work alongside a separate hot water cylinder (often found in the airing cupboard) and a use a cold water tank (often found in the loft). Like a sealed system, this type of system is normally suited to a larger home with a higher hot water requirement.

Open vent boilers, sometimes known as heating only boilers, provide central heating and hot water via a boiler, a storage cylinder housed in the airing cupboard and water tanks in the loft. They are the ideal solution for all house types – from a typical one bedroom/bathroom flat through to a four bedroom property with three bathrooms.
