The temperature of the storage tank depends on the thermal losses
and gains to the tank. The water that goes to the load would probably be
a great deal hotter than 20C but it may be that an external auxiliary
heater brings the temperature up to the delivery set point or it may be
that water is maintained at a higher temperature in a second tank. Ground
water where I live is typically at about 10C so the bottom of a
stratified storage tank could be as cold as that, at least temporarily
until the solar collector or an an auxiliary heater warmed it up.<br>

<blockquote type=cite class=cite cite="">Dear TRNsys users,<br>
I'm working on the modelisation of a solar system with stratified storage
tank. I've seen on the example (name is SDHW) the repartition of the
temperature in the tank. Is it normal that the temperature at the bottom
of the tank is less than 20°C? Is it not dangerous for health to store
domestic water at this temperature?<br>
Thanks for your answer<br>
Best regards<br>
