Solar Hot Water
Forced Circulation Systems
Sometimes known as pumped, split or forced circulation, these systems typically have the storage tank separated from the solar collectors, with the tank located at ground level and the collectors on the roof.
Individual homes
A pump and control unit are utilised to ensure correct water circulation. This allows the collectors to be situated away from the tank. For example, the tank may be situated in a basement while the collectors remain on the roof.
Unlike uncontrolled thermosiphon systems, there is no chance of wasting water from overheating because the solar controller automatically stops the water circulating once the storage tank is full of hot water. It also has inbuilt frost protection for marginal frost areas.
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. 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.
