Solar Water Heater Hawaii


Do you live in Hawaii?

Are you looking for a Hawaii solar water heater?

Why might you want or need to set up a solar hot water heater Hawaii home?

If you live in Hawaii, you may be searching for a good, high-quality solar water heater installation company. Since 2008, new homes built in Hawaii have been required by law to install solar water heaters, so if you’re building a home, this is an especially important type of company to locate.

Solar water heaters are not required by law for existing homes that were built prior to the mandate. However, this upgrade may still be worth it financially, so it’s worth considering a solar heater for your household anyway.

Many solar water heater companies in Hawaii offer discounts for those who are installing solar heaters on existing homes. There may also be tax exemptions available, depending on the year in which you install the heater.

Of course, you’ll also save a lot of money on your energy bill by installing a solar heater instead of a gas or electric one!
