Solar water heaters required in new Hawaii homes

HONOLULU — All new homes in Hawaii will be required to have solar water heaters installed starting in 2010 under a law approved Thursday by the Legislature.

Hawaii becomes the first state requiring the energy-saving systems in homes.

Solar water heaters typically cost home buyers about $5,000 extra on their mortgage, but island residents will save thousands of dollars over the years on their electricity bills, supporters said.

"We owe to our children and grandchildren the promise of a clean and renewable energy future," said Rep. Hermina Morita, chairwoman of the House Energy Committee. "A solar water heater mandate in new home construction ... will result in greater public benefits to everyone at large."

It felt good also.
The only needed hot water I can think of would be for washing dishes. Clothes washing, not so much.

But why... Why do they insist on venting the dryers inside? Isn't the humidity high enough already?

The dryer exhaust is directed into a shoe box sized tank. You need to check it & add water when you start the first load, otherwise you will have dust.

So you have this hot, humid dryer exhaust going into a water tank and out into the room.


As I write this the temperature is 80°F and the humidity is 75%
(When the humidity there gets down to 50% it seems dry, like it does @ 20/30% here.)
