Heat Loss Stainless Steel Tank

The heat loss due to evaporation of water from a surface of an open tank is dominant at higher water temperatures.

Heat loss stainless steel tank.

Our thermex stainless steel hot water tanks are pressure tested to a full 12 bar four times their normal working pressure and injected with 50mm of our hcfc free polyurethane insulation to achieve astonishingly low levels of heat loss which maximises energy efficiency for your customers. Chart is based upon still air. The intersection of line a with scale 3 is the tank volume approximately 17 000 gallons. 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.

Any heat loss through insulated walls is minimal this is especially try for polypro tanks. Connect 12 on scale 2 with 20 on scale 6 line a. This is calculated to be 0 4 x 302 x 90 30 or 7 248 btu hr of. Can be estimated with values from the table above as.
