Storage tank should be insulated with R-4.2, 1"
(2.5cm) thick, for a minimum distance of 5' (1.5m)
or to the wall if it is less than 5' (1.5m).

Solar Storage Tank and add a Tee connection
to the existing piping into the existing water
heating system.
3.
Install an Anti-Scalding valve on the outlet of
the backup water heating systems before distri-
