SFO pressurized solar water tank is for hot water storage of solar heating systems, electric power or gas heating systems. Its capacity is from 150L to 2000L with working pressure 0.6Mpa, and the test pressure 0.9Mpa.
As per different situations,different numbers of heat exchangers (copper coils) can be add inside tank. Some examples are below
In areas with good water quality, you can use tank without coils
Majority of solar heating systems use tanks with 1 coil inside
The two coil water tanks are mainly used for floor heating system and system with backup power like gas heater
SFO pressure water tank is mainly consists of inner tank, outer tank, heat exchanger (copper coils) and polyurethane insulation layer, equipped with PT valve, magnesium rod and check valve.
