interma Pre-heated Copper Coil Solar Water Heater

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
