This autumn, A.O. Smith has extended her product range of thermal solar collectors with copper/aluminum collectors. The water heater manufacturer is following the market development of solar collectors, whilst maintaining the high quality and output of these environmentally-friendly hot water solutions.
The heart of an A.O. Smith solar collector is a full-plate absorber with an eco-friendly vacuum coating. This plate or ‘absorber’ is made of copper for the existing A.O. Smith collector range. In the new version, this plate is produced of aluminum. Right underneath this absorber, the copper meander is situated, that transports the glycol.
The dimensions and the construction of the copper/aluminum collectors is the same as the copper/copper collectors. The output level is practically the same, with the output of the copper/aluminum collectors being marginally (0.126%) lower in comparison to the copper/copper version.
Primary benefit of the new aluminum collector range is the lower purchase price, that may be particularly interesting for larger collector fields. For example, when comparing 2 sets of 15 horizontal collectors each, on frame construction (without drainback), the aluminum/copper version is approximately 6% lower in price.
All thermal solar collectors from A.O. Smith are available in 4 configurations: roof build-on, roof build-in, flat roof frames or wall mounting frames. Sustainability, efficiency and environmental friendliness are key words for these “renewables”. To increase the life of the solar collectors even further and to prevent extremely high temperatures, a drain back module is available as an option.
The A.O. Smith solar collectors allow for a maximum efficiency when combined with the SGE or SGS solar gas water heaters from A.O. Smith. There are two options: condensing high efficiency and thermal solar energy integrated in one system solution (SGE or SGS) or an indirect solar system, that is connected to a water heater of CH by means of an indirect storage tank (IT or ITS).
