Solar Hot Water Heating | Thermosiphon Roof Mounted Systems

Supplier: Toowoomba Solar Centre

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.

Price Guide: POA

The Thermosiphon principle is based on two naturally occurring phenomena:

  • Dark objects absorb heat
  • Hot water rises

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

The greater the temperature difference between the fluid in the collector panels and the water in the tank the faster the flow between them.
