Pre-Heated unpressurized solar water heater

directly connected to tap water, water only go through the copper coil and be heated up rapidly,more clean,high efficiency

water tank:

a:inner tank :0.4mm SUS304-2B

b:PVDF/colorful plate

c:heat insulation layer :55-60mm imported PU

d:one copper coil heat exchanger

e:assistant water tank

f:electrical boost heater (optional)

g:bracket :galvanized steel with powder painting

Feature:

one copper coil is installed inside the tank as the heat exchanger .when waterflows into the copper coil ,it absorbs the heat of the water in the tank via the copper coil therefore the water tank is just a heat storage tank.

 

a: Works under the perssure of pipe water

b:There is no need to wait and hot water is available immediately

c:completely automatic operation

d:Copper coil dimemsion:12-15mm(diametre);24-36m ( length);1mm(wall thickness)

e:Without volatile tubes

f:Copper coil conduction power :=100W

g:Daily efficiency :>56%,and >42%(winter)

h:Heat transfer testing:evaporation end 70 degree centigrade ,condensation end>=63 degree centigrade,contigrade
