Yes. Big time as a matter of fact, and a lot of people in Hawaii have already made the switch. Most folks don’t know this but most of the time, your home’s largest energy consumer is your electric water heater. For families of 3 or more, installing a solar water heater in your home is the best way to save money on your electric bill. Up to 40% as a matter of fact, and we know what electricity costs are like here in Hawaii. With Hawaii Energy’s rebate options for energy saving systems, you can save nearly 70% total cost on the system purchase price in the first year. That’s around $2000 for a typical residential installation after all rebates and tax credits are received thru them. Not to mention the money you will be saving on your electric bill… Prestige Plumbing is proud to be an Hawaii Energy partner enabling us to make that a reality for you thru us. You can find out about these rebates at their website @ https://hawaiienergy.com/for-homes/rebates/water-heating. Also, those of you that have older systems, you can do the same thing and get a whole new system for a few hundred dollars more than what it would cost you to replace a faulty portion of your existing system. Please call Prestige Plumbing for a free estimate to start saving money with solar hot water now.
