Solar Water Heating – Becoming mandatory in a town near you?

Solar water heating is a pretty mature technology at this point. I suppose that it isn’t surprising that it might become a standard feature of new residential construction.  However ti has now become mandatory for all new construction in Hawaii.  That is residential construction, new homes.

I think that overall I am in favor of this for a couple of reasons.  First is that it will generate economies of scale by making it a requirement and thereby making the overall cost less. Second is that it simply makes sense to employ every affordable technology to reduce our footprint on the planet. the fact that it can be packaged as a selling point is a bonus.  The full article is here on (

For those of you who might need a primer on solar hot water here is the government’s site that covers it pretty well:

There is also another way to harness the thermal energy for your building.  There is a new product called Solar Duct that allows you to pre-heat air that would then be used to heat the building.  (

Also from the same company is a configuration that combines the heating of air and conventional solar panels.  This setup helps the effciency of the panels by lowering their overall temperature. (

As always I thank you for your time and interest. Please take the time to Digg, Stumble Upon or add to the other social network of your choice to help me spread the word about these issues. Please forward any questions or suggestions to:
