1.Water tank:<dd>Interior: stainless steel<dd>Exterior:
PVDF
2.Working principle:<ul>
3.When temperature of heat collector reaches the set value,
controller should start circulation
4.Pump automatically
5.Circulation pump makes heat conducting liquid circulate
automatically
6.Heat conducting liquid transfers heat to water by heat exchanger
in water tank
7.In case temperature of circulation pump does not reach set value,
circulation pump should be stop working automatically
8.In case temperature of water tank does not reach T max, then
start electric heater</ul>
9.High efficiency
*0.Multi use
*1.Heat preservation: *2 hours
*2.Lifetime: *5 years
