Case Study: Somerville House – Solar Hot Water

Solar Hot Water – South Brisbane, Qld


Somerville House girls school in South Brisbane built a new Junior Boarding House in late 2009 that was opened in early 2010.
Somerville House commercial solar hot water project
A key aspect of the project was installation of a solar / gas hybrid hot water system to supply the almost 100 teenage residents of the boarding house.

High performance evacuated tube solar collectors were chosen to supply solar heated water in a two stage Rotex hot water delivery system. The first stage is a solar pre-heat and the second stage is a gas finishing plant powered by two commercial grade Bosch 32 series instantaneous gas burners.

The Solar Guys working with Rotex designed and supplied the system, which was installed by the major plumbing contractor on the project. The system was designed to deliver an annual solar contribution of over 60% so as to minimise natural gas usage on the site.
