SFBS system is mainly used for central supply of domestic hot water and hot water supply for commercial buildings.
Depending on different capacities of the water tank,SFBS mainly includes 9 common used models, 150L,200L,250L,300L,400L,500L,600L,800L and 1000L for different water requests.
SFBS20200L Split pressure heat pipe solar water heater
SFBS20200L is split pressure solar water heater. The solar vacuum collector absorbs solar energy and passes heat through the heat pipe to the flow path. Under the drive of the circulating pump, the working substance is heated as it passes through the runner, the heat is passed to the tank, pool or heat exchanger.
This energy can be used for domestic and commercial hot water heating, hot water supply for hotels and hospitals, pool heating, space heating, solar water desalination and thermal power generation.
SFBS is mainly composed of hot water storage tanks, solar collectors, workstations (controllers and circulation pumps), expansion tanks, filling valves, exhaust valves, collector connections and pipeline.

SFBS is a passive circulating split solar heating system. The heat pipe collector absorbs heat energy during daytime and,circulating pumps work under temperature difference control. At the same time, working fluid is heated fast when going through manifold,then transfers heat energy to the water tank or heat exchanger.

• Split pressurized solar heating system has a architectural integration design.
• Solar heat pipe collector, high thermal efficiency, provides medium and high temperature hot water, suitable for use in various environments such as low temperature, high altitude, and hot areas.
• Split pressurized water tank can work together with hot water equipment such as gas heater, boiler, electric heater, heat pump etc.
• The intelligent design of the temperature difference cycle effectively reduces energy consumption.
• Expansion vessel, PT valve, heat exchanger (copper coil),effectively protect the system safely and stably, and extend the service life.

Solar collectors can be installed on the ground, on the flat roofs or inclined roofs where have efficient sunshine.The bracket needs to be fixedly connected with these bases.
Water tank is placed on the ground, preferably indoors.
Solar workstation is better to be mounted on a wall close to water tank.
Circulating pipe is connected by metal pipe like copper pipe or stainless steel bellows, and please pay attention, the PPR pipe is avoided.
