SOLAHART STREAMLINE MLV
SPLIT SYSTEM SOLAR WATER HEATER
Solahart's split system solar water heaters are designed to give you the maximum flexibility of installation locations. The low profile and unobtrusive Solahart solar collectors are mounted on a roof, whilst the storage tank is mounted at ground level out of sight. The electric boosted model can even be installed inside your home. This minimises the visual impact of going solar, while maximising the potential savings from the sun.

KEY FEATURES
The Streamline 322MLV system is available with Solahart's 'L' solar collectors to harvest the sun's heat and transfer it to the water. The L collector with its black powder coated aluminium absorber plate provides economical service in low to high solar gain areas.
Solar energy is transferred directly to the water as it is moved through the collectors by an electric circulator and the heated water is stored in the ground mounted MDV series tank. The electric boosted models are equipped with an in-tank element to ensure a supply of hot water during periods of poor or no solar gain. Alternatively the system can be installed as a preheater with an inline Solahart gas booster water heater.

HOW THE SPLIT SYSTEM WORKS
With open circuit split systems the water is circulated from the tank at ground level through the solar collectors by an electric pump called a 'circulator'. As the sun heats the water in the solar collectors, the increase in temperature activates the circulator. The circulator switches on whenever the water in the solar collectors is hotter than the water in the solar storage tank. The circulator moves the hotter water from the solar collectors through the solar hot pipe to the solar storage tank and the cooler water from the solar storage tank is circulated to the solar collectors via the solar cold pipe to be heated by the sun’s energy. This process continues whilst solar energy is available and the water in the solar storage tank requires heating. The circulator will deactivate when the water temperature in the solar storage tank is around 70°C to 75°C.
The Solahart 322MLV split solar water heater is designed to be installed as an electric boosted solar water heater with its booster heating unit connected to a power supply, however it may be installed with an in-series continuous flow or storage booster. If installed with an in-series booster, then the electric booster heating unit will not be connected to a power supply.
LEARN ABOUT THE SOLAR OPERATION
The operation of the circulator is controlled by the combination of:
-
the hot sensor located at the outlet of the solar collectors. The hot sensor measures the water temperature at the outlet of the solar collectors.
-
the cold sensor located at the solar cold outlet at the base of the solar storage tank. The cold sensor measures the water temperature at the bottom of the solar storage tank.
-
the differential controller located in the solar control unit.
As the sun heats the water in the solar collectors, the increase in temperature activates the circulator. The circulator switches on whenever the water in the solar collectors is hotter than the water in the solar storage tank. The circulator moves the hotter water from the solar collectors through the solar hot pipe to the solar storage tank and the cooler water from the solar storage tank is circulated to the solar collectors via the solar cold pipe to be heated by the sun’s energy.
This process continues whilst solar energy is available and the water in the solar storage tank requires heating. The circulator will deactivate when the water temperature in the solar storage tank is around 70°C to 75°C. The water heater will then enter Over-temperature operation.
During normal operation if the amount of solar energy available reduces, such as when the sky becomes very cloudy or the sun becomes lower in the sky in the late afternoon, and the water no longer gains usable heat from the solar collectors, the circulator will deactivate. The water heater will then enter standby mode.
