FROG - PHOTOVOLTAIC WATER HEATER

Frog is the first ecological and solar water heater patented by Sunerg.
It produces hot water directly from the sun.
The water heater has been equipped with double electric resistance that let to heat  water both by Sunerg’s photovoltaic module and electric heater 1500W.
Sunerg’s PV module powers the water heater which organises the controller FROG spreadeing to the water the solar energy.
FROG is an easy and ecological system in order to save money thanks to solar energy.
What are you waiting for? FROG is the ecological MADE IN ITALY revolution!

Example of energy yield of the FROG system production using a Sunerg’s photovltaic module 400Wp. on a sunny summer day in the south of Italy.
• Average daily electricity production: 2.800Wh
• Daily thermal energy supplied to the resistance: 2.410 kCal
• Daily temperature increase of sanitary water (80 LT): +30°C
• From 20°C temperature at the begining of the day upto 50°C 
• Saved CO2 in a day: 1,8 Kg.
