Insulation materials temperature ranges. Calculate the heat loss from the storage tank using the formula q α x a x dt where q is the heat loss in btu hr α is the heat transfer rate in btu hr ft 2 f a is the surface area in square feet and dt is the temperature difference of the tank fluid and ambient temperature. Example heat loss from an open water tank. Insulated pipes heat loss diagrams.

The heat loss due to evaporation of water from a surface of an open tank is dominant at higher water temperatures. Tank 12 diameter by 20 long. Q evaporation fluid radiation fluid 1040 btu ft 2 hr 10 ft 2 10400 btu hr. Connect 12 on scale 2 with 20 on scale 6 line a.

Hot water in the stainless steel storage tank stays hot longer because there s no flue heat loss plus the tank is protected by a two inch blanket of thermal foam insulation. Any heat loss through insulated walls is minimal this is especially try for polypro tanks.
