The heat loss coefficient depends on the type of tank and the insulation 
level.  The model can handle both insulated and un-insulated tanks so 
it's up to the user to put in a representative value based on the tank 
that they will be studying.

A gas flue is used in bottom-fired gas water heaters and provides an 
escape route through the tank for the products of combustion.
