How the Sol-Perpetua™ System Works

7. PIPING & INSULATION

All piping must be copper with soldered fittings. The riser and downcomer are 12mm (1/2 inch) o.d. copper tubing. For a one storey house they can be 9mm (3/8 inch) o.d. Insulation on the hot downcomer must be rated for 110 C (230 F) temperature.

Six square meters (64 square feet) of collectors will produce about 300 litres (80 US gallons) of 50 C (123 F) water on a sunny day.

The residential pump and heat exchanger module are sized to handle 6 sq. meters (64 square feet) of collector panels. We also make a larger pump for commercial applications and for space heating using wood and gas appliances.

We shall be installing a system using cross linked polyethelene with an aluminum tube sandwiched in the middle. Check back to find out how it works out.
