Conventional water heaters are notoriously inefficient, accounting for about 20 percent of a household’s energy bill. That is why federal and state governments are now offering rebates and tax credits to homeowners who upgrade to heat pump or solar water heaters. Is your water heater aging? Are your energy bills rising? Now is a great time to upgrade to an energy efficient water heater.

Heat Pump Water Heaters

A great option for lowering your water heating costs is to install an ENERGY STAR® heat pump water heater. Heat pump water heaters are twice as efficient as a traditional tank water heaters, cutting your water heating costs in half.

Solar Water Heaters

Solar water heaters are the most efficient way to heat your water, saving you up to 40% on your energy bill. They also last twice as long as other water heaters, 20 years on average. Though the initial cost is greater, the State of Hawaii offers affordable financing through its Hot Water Cool Rates financing program and through programs in Maui and Kauai offering free financing.

Are Tankless Water Heaters Energy Efficient?

Yes! Although not quite as efficient as a heat pump or solar water heating system, tankless water heaters are 24% to 34% more efficient than tank water heaters, according to Energy.gov. Even upgrading to a newer conventional tank water heater can save you 4% in energy costs according to Consumer Reports.

If you have any plumbing needs this is the company to use. They said they would be there at 9:30 and by gosh, they showed up at 9:28 that not a normal thing when it comes to plumbing. Both of them were not they answered all my questions without hesitation and got the job done within 45 minutes even though they said it would take an hour and a half.

-Bob J.

Brayden and Maka worked on a major repair at our home over a time period of four days. We have high praise for both of them, their professionalism, courtesy, friendliness, and reliability. Steve’s Plumbing is lucky to have these two fine employees.


Shon Bolo was very courteous. He was very informative about how Plumbing is just as important as the engine of a car. He was very respectful. Even though I wasn’t able to get everything done as expected. Shon was able to install my laundry tub to get my washer ready to drain and connected. Definitely would recommend shon bolo to friends and neighbors. Thank you very much for the wonderful job. Great service Shon!!
