Solar Water Heating
Cut your water heating costs up to 90% with solar water heating.

A typical residential solar water-heating system reduces the
need for conventional water heating by about two-thirds. It
minimizes the expense of electricity or fossil fuel to heat the
water and reduces the associated environmental impacts.

There's never been a better time to buy a solar water heating
system. If you are a year-round Hawaii resident and have an
electric resistance water heater, you can save money and help
to conserve valuable natural resources.

Hi-Tech Plumbing Corp. (HTPC) has been installing solar
water heating systems since 1989 and was the first plumbing
company to install over a thousand systems via the Hawaiian
Electric Company’s (HECO) Solar Program.  To date, HPTC
has installed thousands of systems through out Oahu.

Active Solar Water Heating System
An active system has a flat-plate collector on the
roof and a solar storage tank which is usually
located in a garage or utility room. An electric pump
circulates the water between the collector and the
indoor solar storage tank whenever solar energy is
available and needed to increase the temperature of
the water in the solar storage tank.
