What temperature should a hot water storage system be heated?
If the hot water storage system is partially heated by solar power or heat exchange system (wetbacks or solar heat transfer system), the temperature must be boosted at least 60°C or higher on a daily basis. The Building Code requires that hot water be delivered at a temperature that avoids the likelihood of scalding.
Is water a suitable heat storage material?
Consequently, water is a suitable heat storage material, and water is today used as a heat storage material in almost all heat stores for energy systems making use of a heat storage operating in the temperature interval from 0 °C to 100 °C. 2.2. Principles of sensible heat storage systems involving water
Why is water a good candidate for sensible heat storage?
Water is naturally a good candidate for sensible heat storage (heat storage due to a sensible temperature rise of the storage material) due to its high specific heat and density in the liquid phase. Furthermore, it is harmless, relatively inexpensive and widely available.
What are the thermal characteristics of a hot water store?
The most important thermal characteristics for hot water stores are: heat storage capacity, heat loss, heat exchange capacity rates to and from the hot water storage and temperature stratification in the hot water store.
What are the principles of sensible heat storage systems involving water?
Principles of sensible heat storage systems involving water Hot water stores are today based on water contained in tanks made of steel, stainless steel, concrete or plastic or by water volumes placed in envelopes consisting of different watertight materials.
What is a heat storage tank?
Heat storage tanks are one of the most common and mature heat storage techniques, as they meet one of the most used demand items, hot water. They are also one of the most known energy storage methods of renewables, as they are used in the solar domestic hot water storage systems.
