Solahart J Series Solar water heater
Key Features
The Solahart J Series is a roof mounted, closed circuit solar water heater. It is recommended for use in frost or poor water chemistry areas.
The J Series features Solahart’s revolutionary multi-flow collector to extract the maximum amount of energy from the sun. This is used to heat the Hartgard fluid in the collector which rises into the heat exchanger where the heat is transferred to the water inside of the tank. The ceramic lined tank has a protective anode and the SP Free Heat series features additional protection.
- Space saving roof mount design
- Reliable, low maintenance operation
- Can cut water heating energy use by up to 55%^
- Reduces household greenhouse emissions
^ Energy savings of up to 60% . Any savings will vary depending upon your location, type of Solahart system installed, orientation and inclination of the solar collectors, type of water heater being replaced, hot water consumption and fuel tariff.
† Solahart Warranty Details: 5/5/5 warranty; 5 year cylinder and collectors supply, 5 year parts, 5 year labour. 10/5/5 warranty, 10 year cylinder and collectors supply, 5 year parts, 5 year labour.
