Advantages-Heat Pipe Solar Water Heater

Previous      Next

Þ  Highly efficient absorber, with daily average efficiency over 50%

Þ Quick start up, with the heat pipes transferring heat energy into the storage tank in one direction

Þ Able to withstand pressure of 0.4 MPa (4 atmospheres), so can be connected directly with city water mains

Þ The storage tank and the heat pipe are metallically sealed

Þ No water is inside the evacuated tubes; the solar water heater can still function with several broken tubes

Þ Can be used all year round in cold climates: no water in the tubes to freeze

Þ Highly efficient insulation with polyurethane foam keeps tank heat loss to a minimum

Þ stainless steel storage tank inner cylinder stands 100,000 fatigue tests without any distortion

Þ Long service life, can be used at least 15 years

Þ Simple modular structure of diffuse flat plate reflector makes for easy assembly and installation

Þ Large-scale solar hot water systems can be installed either with parallel or series connections of these units

Þ Electric heater and controller make a complete hot water system
