A Few nice words from happy customers:

"My husband likes a hot pool, at least 90 degrees, and we were running the gas heater all the time. We thought, Wouldn’t it be cool to take advantage of all of this great sun in Arizona?

This year, we swam until October and didn’t run the gas at all. Now, we’ve totally eliminated that gas cost. We use our pool a couple of times a week and  we know the pool is always ready. We don’t need to plan ahead like we did with the gas heater.

The installation crew did a phenomenal job. They were able to hide the pipes so well that they blend right in with the house. The Heliocol has been a great addition to our home and a great investment in our pleasure. It was important to us to have a warm pool and the flexibility to swim when we wanted. It was a good investment and I would do it all over again."

"We decided to get Heliocol after we talked to our neighbors across the street. They raved about what a high quality experience it was. Sure enough, once the Heliocol was installed and running, the heat was almost immediate. By the next day our pool was at 88 degrees. It worked like magic.

We had a great installation experience, too. The crew did very neat work and they were so polite.

We think it’s a great value and it really adds to the resale value of the house. We just set it and forget it. We have friends with gas pool heaters who have only heated their pools twice a year because it’s so expensive to run. But we don’t have to feel guilty about having a warm pool."

I would like to take this opportunity to compliment the workers on the crew that recently installed our solar (electric) panels on my rooftop.…I also want to mention your salesman Mark Walters. What a credit he is to your team. We became acquainted with Mark in 2004 when we purchased our salt water system for our pool along with your misting system. We also have solar panels for the pool and your heat pump to heat the pool in the winter months. Needless to say we are truly a Heliocol family.

It's been about six weeks since our Heliocol solar and Comfort mist systems were installed. The solar system works great! We have been swimming in a 90-degree pool every day since installation.... We enjoy our backyard very much and entertain frequently.

With our new misting system, we have been able to bring the temperature down 20 degrees in the heat of the day! Our misting system will enable us to use our patio more during the summer months.....We made the right decision!.....It's a great feeling knowing we chose the best!

Feel free to use this letter as a recommendation to Heliocol Solar and Misting Systems!

I work as an engineer, and am impressed with Heliocol's design, especially the way it mounts to my "foam" roof. The system does wonders for the pool temperature. We have combined it with a pool cover and are very happy!

    Points to the installation team for being friendly.

Please accept my special thanks for the quality of work provided in completing the solar pool heater and mist system that were installed in my home.

Last June your firm [Heliocol Green Energy] installed a solar heating and salt water system on our pool in Scottsdale. Both systems have performed very well and we are very satisfied with the results. While the heating system has produced the results we desired, we are especially happy with the Salt water chlorinator. The water remains sparkling and the "clean feel" of the water has been a most pleasant extra benefit. The service and attention to the operation of the equipment by your personnel has been outstanding.... In summary, we can say that we are very happy with the equipment and service received by Heliocol.

Very truly yours,

There are a few people I can count on in this business and I feel you are in that group, not only because you really know what you are doing, but you genuinely, consistently care about the customer's needs too.

Good Luck,

"...As I was doing my exercises in the pool today I thought I should tell you that my solar unit, since installation in 2001, is still coming on every day and doing its thing.

This year, I was able to start swimming by March 15th, the second earliest I've been able to get in the pool since the beginning.

Having MS that affects my mobility and being able to get around, the pool is the only semblance of any exercise I get and it really helps. I'm faithful about getting 1-2 hours of workout every day. The solar heater still does a good job of heating up the water.

So, Thank You for your product and don't hesitate to use me as a referral.

By they way, our electric bill this month was just under $27 "
