Buffer tank

Boiler Buffer Tanks are engineered to regulate temperature, water volume, and
flow within heating, cooling, and domestic hot water systems. Functioning as a
thermal “battery,” they store heated or chilled water, releasing it as needed
to accommodate fluctuations in system demand and prevent frequent cycling of
boilers, pumps, or other heating and cooling
equipment.https://www.hotwatertankfactory.com/ , buffer-tank.html
