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.
Heat loss stainless steel tank.
Insulation materials temperature ranges.
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.
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.
