Insulated pipes heat loss diagrams.

Heat loss stainless steel tank.

The intersection of line a with scale 3 is the tank volume approximately 17 000 gallons. Any heat loss through insulated walls is minimal this is especially try for polypro tanks. This is calculated to be 0 4 x 302 x 90 30 or 7 248 btu hr of. Tank 12 diameter by 20 long.

A high grade 90 10 cupronickel heat exchanger coil restores full water. Insulation materials temperature ranges. The intersection of this line with scale 4 is the surface area of the cylindrical portion of the tank approximately 800 sq. Example heat loss from an open water tank.

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