As a pioneer in solar hot water technology solutions since 1976, Heliodyne Inc. is proud to be America's oldest manufacturer of solar hot water collectors and systems. Through innovative design, superb product lines, and dedicated service & support, we've become an industry leader that you can trust. Heliodyne has become a leading manufacturer and provider of solar hot water systems throughout the United States and many parts of the world. Over the past 30 years, our experience in the industry has allowed us to continually refine and improve our products, and thereby maintain our reputation as a market leader. We develop and assemble every key component at the Richmond, California facility, for quality assurance purposes. All our products are built with the finest materials for high heat-transfer rates, increased efficiency, durability, and extended lifetime energy-production. In fact, there are thousands of Heliodyne systems still running smoothly that were installed in the late 1970's, a true testament to their quality and lifespan.

Also contributing to the overall quality of our Heliodyne products is the simplicity and ease of installation. It's a major reason why our products are so popular among contractors and installers nationwide. Superior materials and design lead to a slightly higher-priced system that is more durable, efficient, and a better value over time. Such a system also produces a higher heat output, which means more hot water for your business; at Heliodyne, we offer value through performance. Although a high-quality Heliodyne system might not be the least expensive, the value, over time, will be quickly realized. Heliodyne systems perform better, last longer, and require hardly any maintenance, saving you more money in the long run. At Heliodyne, we offer performance, reliability, and value for you and your home.

The GOBI line of solar flat-plate collectors is one of the industry’s highest-rated collectors. Over 30 years of design and engineering refinement have gone into making it a world class performer for heat output, efficiency, and durability. The collector is available in 3 sizes (4’ X 6’, 4’ X 8’, 4’ X 10’), 2 surface types to choose from (blue sputtered, and black paint), and constructed with an anodized aluminum frame, making it versatile and suitable for all types of solar heating applications. Collector mounting is now a simple, trouble-free experience thanks to the pre-configured mounting hardware packages. Rated by SRCC and IAPMO as one of the industry’s best-performing collectors. The Helio-Pak (HPAK) Closed Loop Heat Transfer Appliance is an all-in-one heat-transfer assembly, specifically designed to simplify solar hot water systems and provide maximum heat transfer that is sixteen times faster than other heat transfer appliance on the market. The Helio-Pak Pro Closed Loop Heat Transfer Appliance (with pre-installed Delta-T Pro controller and Wi-Fi capabilities) further enhances the residential solar hot water system, with the addition of user-friendly customizable settings, remote navigation, and expanded system performance data. The Helio-Flo Open Loop Heat Transfer Appliance is a heat-transfer appliance designed specifically for open loop active systems, with easy installation in mind, and heats sixteen times faster than any other heat transfer appliances on the market. The Solar Hot Water Module guarantees you a constant supply of fresh hot water by means of a temperature regulation system, which avoids any delays or temperature fluctuations. Heliodyne Storage Tanks have been specifically designed for use with SHW systems. Design features such as built-in sensor ports and solar in/out connections minimize installation time and optimize performance, compared to using traditional off-the-shelf water heaters. The standard Delta-T and the advanced Delta-T Pro.Control Units are what monitors the solar hot water system, sensing when there is solar energy to be collected and automatically activating the circulation system. We offer 2 types of control units. The Polysun Solar Planning software is simple to use and assists in solar system design.
