Thermosiphon Systems
 Thermosiphon systems call on Mother Nature to circulate water through the solar collectors to the storage tank using the thermosiphon principle that hot water rises naturally, hence eliminating the need for circulating pumps or other moving parts. Chromagen's thermosiphon systems are the most straightforward, economically viable and energy efficient designs available. A gas or electric backup booster provides energy during cloudy weather, so you can have plenty of hot water when you need it.
The thermosiphon system includes:
- Solar collector(s) of your choice
- Storage tank sized to suit your requirements
- Connecting Kit
Tank sizes vary from 150 to 300 litres so there’s a size to suit your particular needs. Depending on your location and climate you may choose an Open-Loop or Closed-Loop system.
Open-Loop System
Suitable for warm climates
In Open-Loop Systems the water circulates through the solar collectors and is heated directly by the sun. These systems are suitable for climates that are mostly frost-free and have good water quality.
Closed-Loop System
Suitable for cooler climates
Closed loop systems utilise a heat exchanger to heat the water indirectly with the sun. They are particularly useful in frost prone areas and areas with poor water quality.
