Solar energy water heater is one of renewable energy resource. these are environmentally friendly and can now be installed on your roof to blend with the architecture of your house easily. The system has maximum efficiency & takes minimum installation time & can reduce a home’s energy consumption by as much as 50%.

o This conversation is going no where. It’s lacking the place of a good leader to head the things to come out on conclusion.

Aloha.I agree with the state in making solar hot water systems manditory on all new homes,but this is going to shut down some of the little guys who cannot afford it in their budget.I think making this code applicable to homes over,say,1000 sq.ft.would be more realistic and consideration for using a tankless water heating system should also have some merit.I am all for increasing energy efficiency,but some allowances should be made.

Solar Water Heaters for domestic applications are great and the Authorities in Hawaii should be congratulated on their forward thinking. However, there is also another water heating technology that has been developed to a level now, that is very similar to the efficiency of a Solar Water Heater – and that is an “Air to Water Heat Pump”. These units can still “collect” free energy from the air during the night time, in heavily forrested areas, or during rainy or cloudy periods. The Heat Pumps are also fantastic and very cost effective for Commercial applications, such as Motels, Hotwls, Large restaurants, Fitness Centres, and any application where large quantities of hot water is required over long periods of each 24 hour day. I spent 15 years in the renewable energy industry involved in International Sales, and I believe that Air to Water Heat Pumps would be ideal in the climatic conditions experienced in Hawaii. Another big advantage with the Heat Pump products is that installation is so much simpler and therefore not as expensive when compared to a domestic solar water heater, and there is no need for any equipment to be installed on the roof. Everything can be installed at ground level.

This seems like a really good idea for Hawaii, I don't think it's necessary to require solar water heaters in other states, but it'd be nice if more people were aware of them. Austin solar water heater

in Austin solar water heaters are not mandatory(yet) but the city is offering a $2000 rebate for anyone who installs one, when you add this to the federal credit, over %60 of the system is paid for right off the bat making payback about 3 years.

HELLO, AND THIS IS GREAT NEWS, EVEN FOR THOSE OF YOU THAT DONT REALIZE THE SAVINGS THAT CAN BE HAD, WHEN YOU PLACE THE SUN AT YOUR SERVICE TO PRE HEAT THE WATER, AND THEN HAVE THE WATER IN A INSULATED TANK, AND THEN WHEN YOU NEED THE HOT WATER IT GOES FROM THE INSULATED TANK TO THE ON DEMAND WATER HEATER,( THE WORK THE ON DEMAND HAS TO DO IS MINIMAL) AND THE SAVINGS OVER THE LIFE OF THE USERS IS ASTRONOMICAL, AND IS GREAT FOR THE WORLD, MOST FOLKS DONT REALIZE THAT CONVENTIONAL WATER HEATERS ARE ON ALL OF THE TIME, IMAGINE LEAVING YOUR CAR ON ALL OF THE TIME- SO THAT WHEN YOU NEED IT ITS READY TO GO, SO WAY TO GO HAWAII
CHAIO AND ALOHA. MARIO PALMA.

The new Hawaii law is bull sh.. it was passed to help the gas co install gas – fired tankless water heaters ! and install at least one other gas appliance ! it kills the 35% state tax credit ! bill has huge loopholes ! see article by michael wilmeth Solar water heating required in new homes in Hawaii
