Answer: the buffer tank stores the surplus hot water from a boiler in order to restore it when the latter is not working.

A buffer tank is capable of producing hot water by itself, but most often it complements an already existing central heating system. Its role is to store the excess hot water produced by a boiler (or a heat pump), then to restore this hot water when the boiler is not operating. Thus, your boiler is started less often, which saves valuable savings to the owner. A buffer tank works with all types of boilers. The capacity of a buffer tank should be around 10 liters per square meter heated in the home, but let a professional tell you the capacity you need. The price of a buffer tank starts at 400 € for the smallest models. You too, send us your brico question
