SOLAHART L SERIES
THERMOSIPHON ROOF MOUNTED SOLAR HOT WATER
The L Series is our most popular system and features a roof mounted, open circuit solar water heater.
It’s available in two sizes: 180 litre or 300 litre.
Solahart’s roof mounted tank systems save space at ground level and their elegant simplicity make them efficient and reliable. The Solahart L Series is a roof mounted, open circuit solar water heater specifically designed to provide economical service in medium to high solar gain areas.
The smaller volume of the 181L makes it ideal for applications where low volumes of solar hot water are required, e.g. small units or retirees. The larger 302L system is ideal for families, and features 2 collectors in addition to it’s larger 300 litre capacity.

KEY FEATURES
Solahart L Series is a solar water heater specifically designed to provide economical service in medium to high solar gain areas. The black polyester powder coated aluminium absorber collects the sun’s heat and transfers it to the water in the copper risers. The increase in temperature causes it to rise and move into the storage tank where it displaces cooler water which then travels back into the solar collectors to be heated by the sun.
The tank features Solahart Super-Shield® enamel for enhanced protection, as well as a protective sacrificial anode to improve the life of the tank. Free Heat Models also feature a larger anode for enhanced tank protection.
L systems can be installed with an optional Thermosiphon Restrictor Valve (TRV), an over-temperature protection system, to restrict over performance during periods of high solar radiation and lower hot water draw off.
These direct systems have no frost protection and are not suitable for harsh water regions. Speak to our team about what product is best suited to your property.

HOW ROOF TOP SOLAR SYSTEMS WORK
The 302L solar system has its vitreous enamel lined solar storage tank installed on the roof directly coupled to the solar collectors. It works on the simple scientific fact that hot water rises. As the sun heats the water in the solar collectors, the increase in temperature causes the water to rise through an insulated copper pipe into the storage tank. Copper is used for the risers for its high thermal conductivity ensuring the maximum amount of heat energy is passed to the water. This allows cooler water from the solar storage tank to flow into the solar collectors to be heated by the sun's energy. This process continues while solar energy is available.
The L Series has a ceramic lined tank with a protective sacrificial anode. The L Free Heat features additional anode protection. L and L Free Heat systems can be installed with an optional TRV over temperature protection system to prevent over performance during periods of higher solar radiation and lower hot water draw off.
