With Australia’s abundant sunshine it makes great sense to get your hot water FREE from the sun.

With a Solahart solar water heater you can enjoy big savings on your energy use and reduce your greenhouse gas emissions.

Solahart’s solar hot water systems use a range of technologies to provide efficient and cost effective solar water heating solutions for all Australian climates.

Thermosiphon Roof Mounted Solar Hot Water

Solahart’s roof mounted tank systems save space at ground level and their elegant simplicity make them efficient and reliable. All Solahart solar hot water systems, where the tank is roof-mounted, use the Thermosiphon principle to collect heat from the sun and transfer it to your hot water. The Thermosiphon principle is based on two naturally occurring phenomena:

  • Dark objects absorb heat
  • Hot water rises

Solahart solar collectors are coated with a heat-absorbent surface. This coating absorbs the energy from the suns rays and heats the fluid in the collectors. As the fluid heats, it rises to the top of the collectors and into the tank where it displaces cooler fluid which flows in to the bottom of the collectors where the process is repeated.
