Ejai solar technology Italy market 300L pre-heated solar powered water heater, with copper coil heat exchanger
YYJ-P01 pre-heated solar water heater
Working principle:
1.One copper coil is installed inside the tank as the heat exchanger
2.When water flows into the copper coil, it absorbs the heat of the water in the tank via the copper coil
3.Therefore the water tank is just as heat storage tank
Feature:
1.Use the copper coil as the heat exchanger, according to international fashion trend, it is simple to install and use
2.It takes the advantage of the tap water pressure, it is easy to operature and install
3.The water can be heated rapidly, so it can produce the high quality hot water
4.The water come from the copper coil, so it is clean and drinkable
Application :
1.Good solution for areas where people have demand for good water quality
2.For cold areas people have a large demand for hot water
3.Places where there is daily needs of hot water
