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.


The following warranty applies to the Solahart L series. Free Heat 10/5/5 warranty, 10 year cylinder and collector supply, 5 year parts supply, 5 year labour; 5/5/5 warranty, 5 year cylinder and collector supply, 5 year parts supply, 5 year labour; applies only when installed as a complete new system.
