The
roof's structural strength is assessed (by the installer) to
ensure that it can support the weight of the system. |
| • |
The
collectors are positioned facing north. Typically they are mounted
flush against the roof so their angle above horizontal is around
20 to 26 degrees. Increasing this tilt angle will improve winter
performance in Perth but may add to installation costs. |
| • |
The
solar collectors are not excessively shaded by trees or nearby
buildings, particularly when the sun is low in the sky during
winter. |
| • |
The
storage tank and solar collectors are as close together as possible
to reduce the length of the connecting pipes (in gravity feed
and pumped systems). |
| • |
All
components, including pipes, are well insulated. |
| • |
The
booster control is in an accessible location with an indicator
light and a timer switch to optimise solar gain in cooler months. |
| • |
Frost-protection
is included for areas where freezing conditions are possible. |
| • |
A
thermostatic tempering valve is installed or included if you
wish to avoid water being too hot during summer. |
| • |
The
system is suitable for the water quality in your area. |
| • |
All
plumbing and electrical work is done by a licensed contractor.
