This type of solar water heater works with high pressure. It uses the heat pipe to deliver the heat energy and is the most efficient. No water circulates through the heat pipe, therefor no water is lost, therefor there is no water loss when a tube is broken or damaged through whatever reason - even during the coldest winters. Each vacuum tube can work independent, so it can still operate in the event of occasional tube breakage. The collector absorbs solar energy and transmits it to the water tank (geyser) through circulation when the temperature difference of the collector and tank (geyser) reaches the set valve and the controller starts the circulation pump automatically.

Use with the TS15-DC pump with solar panel, and TK-SC6 solar controller
The most professional Solar DC hot water pump for solar hot water system and powered solar panels. This is a 12V pump and a transformer is needed.
Certificates: CE, RoHS, ISO9001
TK-SC6 Solar Controller
The solar circut pump is triggered immediately when the switch-on temperature difference between the collector array and the storage tank is reached. Whent he temperature difference bewteen the collector array and the storage tank drops below the switch-off temperature difference, then the solar pump stops working.
