Most professional solar installers agree that solar domestic water heaters should adequately supply about 90% to 100% of a site's total hot water use during the warmest and sunniest months of the year.
Larger storage tanks reduce the periods when the HRL flow rate between two storage tanks has to be slowed to balance the load around one of the tanks and to prevent the tanks becoming full or empty. An optimum tank volume of 25 m 3 for all three tanks that minimises total cost can then be Thermal Expansion Tanks Wessels CompanyThe tank uses compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools. These tanks are designed using a flexing Butyl barrier that separates the stored water from the captured pressure control air cushion.Using Low-Yielding WellsPressure Tank Storage. The pressure tank allows a water system to operate automatically. It is, in a sense, a storage tank--but it has very limited storage capacity.
