240L Heat Pipe Solar Water Heater Pressurzied Type Solar Geyser

PRODUCT DETAILS

Working Principle of Compact Pressure Solar Water Heater

Working principle

The vacuum tubes absorb and convert solar energy into thermal energy, and transfer to the central heat pipe via the aluminum fin. The heat pipes have tiny amount of purified water sealed inside at depressurized condition. When heated, the water inside the heat pipes vaporizes at low temperature (about 30 C), the vapor rises to the condenser and heat energy is conducted to water (inside the tank). When vapor is cooled down, and becomes condensate, falling to the bottom of heat pipe. By continuously circulating in this way, heat is carried from outside to the water inside the tank.

Advantages of compact pressure solar hot water heater:

Comparing with non-pressure and pre-heat solar water heater:

1. Heat pipe tubes for in-direct solar water heating, more safe, fast, anti-freezing;
2. No system drainage when one or several tubes are broken;
3. High pressure tank connecting with city water directly to get high pressure hot water;
4. No need to install on roof top to get hydraulic water pressure;
5. Less heat loss with safety valve closed tank;
6. Almost maintenance freely system;

Comparing with split heat pipe solar water heater:

1. More lower cost;
2. More simple structure and installation;

Comparing with riwatt pressure flat plate solar water heater:

1. Higher efficiency collector, much lower heat loss;
2. riwatt heat pipe solar water heater have super anti-freezing performance for cold weather;
3. No system drainage when one or several tubes are broken;
4. Convenience in parts carrying and installation;

Special features of compact pressure heat pipe solar water heater
