To estimate your family's annual water heating expense, use the energy guide label attached to your heater.

To estimate your monthly water heating expense, you can average your last 12 electric bills and multiply by .3 (or 30%).

Once you've found your monthly water heating expense, you can approximate the savings that a Guardian solar water heater can provide you. Guardian solar water heaters are designed for maximum efficiency. In fact, Guardian solar systems are so efficient that they will, on average, supply 80-90% of your annual water needs. That means 80-90% of your water expense (which remember, may be nearly a third of your total average electric bill) can be saved by installing a Guardian solar water heater.

If you multiply your estimated monthly water heating expenses (as calculated above) by .8, you will approximate how much a Guardian solar water heater will save your family every month. Multiply that figure by 12 (months) to estimate your annual savings.

Not only are Guardian solar water heaters efficient and economically smart, they are also completely self-sufficient. You won't ever have to worry about having hot water. The Guardian solar water heater takes care of itself. It knows when to collect heat from the sun and when not to. It knows when no electricity is needed (which is almost all of the time) and when to provide back-up heat to insure your comfort. Guardian solar systems are so smart that you can kick back, take a deep breath and enjoy the savings it provides you.

Guardian solar water heaters have withstood the test of time. For over 20 years, similar heaters have performed faithfully, with recent improvement in product technology and design, your Guardian solar water heater can be expected to last, trouble-free, longer than ever before. In fact, Guardian solar water heaters are so efficient, reliable and durable that the savings it provides should pay for itself many times over.
