Detailed Description

Description: Pre-heating solar water heater provide heat water by a copper coil inside water tank. Working principle is more advanced than thermosyphon solar water heater, copper coil can connect with water tap directly, hot water inside water tank transfer heat to water in copper coil, which provide more clean water with much more pressure, then people can use the water very conveniently. Tank installation is subject to local area. Such solar collector system is suitable for single or multiple solar system. For example, family solar water heater, solar water swimming pool and solar water furnace system. It's the best choice in cold area or poor water quality area. Features Copper heat pipes for rapid heat transfer Reliable, efficient, twin-glass solar tubes　 Designed to accept mains pressure cold water　 Copper coil heat exchanger can be used as part of a closed or open loop system, providing heating to a main hot water tank　 Easy plug-in installation　 Assistant tank capacity 2L,5L,10L,20L,30L,60L,100L,150L etc Material Copper heat pipes for rapid heat transfer, Copper coil heat exchanger can be used as part of a closed or open loop system, providing heating to a main hot water tank Copper Coil Material: Red copper Size: Φ14*1mm Outer tank 0.4mm thickness Powder coated colour steel Inner tank 0.5mm thickness SUS304-2B food grade stainless steel Vacuum tube Material: Borosilicate glass 3.3,AL-N-AL absorb coating Size: Φ58*1800mm Quantity: Heat pipe Material: Copper pipe Size: 14*80*1720mm Sealing Silicon gel Frame 1.2mm thickness Zinc-plated with plastic spray coating Insulation 55mm thickness polyurethane foam Installation angle 20,38,40,45 Assistant tank capacity 2L,5L,10L,20L,30L,60L,100L,150L etc Model Vacuum tube Water tank Absorb area(m2) Application people(no.)
