Solar-Divicon-HX
Solar heat is transferred
to solar tank via integrated
double wall heat exchanger
Integrated solar control
operates solar pump and
DHW pump
Uses any standard DHW
storage tank
DHW storage tank with upper
electric element creates
a “one tank” solar system

Solar heat is transferred
to internal heat exchanger
coil of solar tank
External solar control operates
solar pump
Uses Vitocell-V/B DHW
storage tank complete with
internal heat exchanger coil
Dual coil tank complete
with boiler back-up provide
a “one tank” solar system
