How do solar thermal systems work?

A solar water heating system takes thermal energy from the sun and adds it to your hot water in your home. It preheats the cold water from the ground before it goes to your existing hot water heater.
Included in a typical system:
- Solar collectors (typically 1 (4′x8′) collector for every 2 people in the home)
- Lineset – 3/8″ refridgeration grade soft copper with high temperature closed cell insulation and thermostat wire
- Energy pack or pump station including pump, heat exchanger, expansion tank, etc.
- Storage tank for solar heated water
- Solar controller and Wireless energy monitor
A solar water heating system is generally sized to do about 90-100% of the water heating during the summer months. The system may heat only 20-30% of the hot water during the winter. For this reason, a back up water heater (usually the homes existing hot water heater) is still required to bring your hot water up to a useful temperature.
A 2-collector Enerworks solar water heating appliance will heat up to 60% of the hot water for a family of 4.
