Thermosiphon Solar Hot Water Heating: SunEarth Sunsiphon

SunEarth Sunsiphon Solar Hot Water System

SunEarth is a company founded in 1978 on a foundation of environmental stewardship. They are leaders in renewable residential energy, and have many systems available to provide clean, free energy for your green home.

One of the systems available from SunEarth is the SunSiphon solar hot water heating system. A thermosiphon system is a completely passive design that relies on simple physics to circulate fluid through the solar collectors instead of pumps and other electrical controllers found in active systems.

When the sun's energy hits the solar collectors in the SunSiphon system, it heats an anti-freeze unit within them, which rises due to buoyancy into a heat exchanger in the bottom of the storage tank. The fluid transfers heat into the tank, heating the water. When the fluid cools, it sinks back into the solar collectors and the process begins again.

When there is no sun, the fluid is not heated and the circulation process is stopped. During these periods, a traditional gas or electric hot water heater can augment the SunSiphon to guarantee an uninterrupted supply of heated water.

The simple design and lack of any moving parts or electrical components help to make the SunSiphon solar hot water heating system a reliable, long-term solution to hot water heating.

Depending on the climate and number of people in the home, prices for the SunEarth SunSiphon system can vary. Typical costs (installed) can vary from $2000 to $6650. Federal and state tax credits are available in most areas that can cut the cost drastically. Your solar hot water dealer will help you determine the size of the system you will need, and also assist with applying for all available tax credits.
