Heat pipe pressurized solar water heater

The principle of Heat Pipe Pressurized solar water heater
Step 1: Evacuated tubes absorb sunlight and convert it to usable heat.
Step 2: A vacuum between the two glass layers insulates against heat loss improvement efficiency. The heat transfer fin helps to transfer heat from the evacuated tube to the to the copper heat pipe.
Step 3: The heat pipe contains a small amount liquid which forms steam when heated, rapidly transferring the heat up to the water in the storage.

Flat plate pressurized solar water heater

Features for Flat Plate solar heater heater
1. Safe and steady: Flat plate solar collector uses all copper fuild tube;system operating is steady and safe.
2. Pressurized operating: working pressure is 0.6Mpa.
3. High heat efficiency: absorbing coating of the collector is black chrome or blue sputtering; absorbing rate is 92～96%, emission rate is 5%-15%, heat efficiency is high.
4. Good temperature preservation: thickness insulation layer is 50mm;constant temperature high pressure quantitative foam; less then 5℃ per 24hours.
