Thermosiphon KF Series

The Solahart Kf Series is a roof mounted, closed circuit system specifically designed to provide higher efficiency for use in low to medium solar gain areas.

M T Carroll Ltd

The higher efficiency absorber with its Black Chrome Selective Surface maximises the absorption of available solar energy while the closed circuit design makes it suitable for frost prone or harsh water areas.

The Kf Series features Solahart's revolutionary multi-flow collector which uses a huge 35 risers to extract the maximum amount of energy from the sun.

The double ceramic lined tank has a protective sacrificial anode and the Kf Free Heat features additional protection. The tank is equipped with an electric booster, alternatively an in-line gas booster is available.

Most Kf and Kf Free Heat systems can be installed with the HartStat OTP (over temperature protection) system to prevent over performance during periods of higher solar radiation and lower hot water draw off.

* Energy savings of up to 55% to 90% shown are based on Australian Government approved TRNSYS simulation modelling using a medium load. Savings and incentives 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. Maximum financial savings off your hot water bill are achievable when replacing an electric water heater on continuous tariff. Refer to for further information.
