Solar Water Heating Solutions by Alternate Energy Technologies (AET): Superior Replacements and
Flat Plate Collector Advantages


At Alternate Energy Technologies (AET), we pride ourselves on providing high-quality solar water heating solutions that not only meet the demands of modern energy efficiency but also offer seamless compatibility with existing systems from other manufacturers. Whether you’re looking to upgrade or replace aging systems, AET’s advanced flat plate collectors deliver superior performance, durability, and ease of maintenance, making us the go-to choice for both residential and commercial solar thermal installations.


Direct Replacement for Leading Manufacturers
Maintaining performance is key as solar water heating systems age. AET makes switching to our reliable flat plate collectors simple, offering direct replacements for several top-brand systems. If you're using systems from manufacturers like Solar Skies, Caleffi, HTP, or Oventrop, AET’s solar collectors are designed for direct compatibility, ensuring a smooth transition to a more efficient and durable system.


Additionally, while we don’t manufacture evacuated tubes, we’ve built a reputation for providing effective replacement solutions for Kingspan, Apricus, and other evacuated tube systems. By switching to our flat plate collectors, users of these tube systems can experience greater reliability, less maintenance, and more consistent performance.


Why Switch from Evacuated Tubes to Flat Plate Collectors?


Many homeowners and businesses currently using evacuated tube systems, like Kingspan and Apricus, are finding that transitioning to AET’s flat plate collectors brings long-term benefits. While evacuated tubes have been popular in colder climates due to their vacuum-sealed insulation, they often come with drawbacks in warmer or moderate climates. Here’s why AET’s flat plate collectors are the better choice:

  • Increased Durability: Evacuated tubes are more prone to damage from external factors like hail,
    debris, or temperature fluctuations. AET’s flat plate collectors are robust, built with toughened
    glass and high-quality materials that offer long-lasting performance.
  • Superior Performance in Warm Climates: Flat plate collectors are known to outperform
    evacuated tubes in warmer climates, capturing solar energy more efficiently under direct
    sunlight and providing reliable hot water throughout the year.
  • Lower Maintenance: Evacuated tubes are more delicate and often require frequent
    maintenance and part replacement. AET’s flat plate collectors, by contrast, are designed to be
    low-maintenance, offering superior reliability with fewer maintenance needs over their lifetime.
  • Cost Savings: In addition to being more durable, flat plate collectors generally have a lower
    upfront cost than evacuated tubes. Plus, the reduced need for repairs and replacements results
    in long-term savings.

    maintenance than evacuated tube systems, meaning fewer headaches and lower operating
    costs over the life of the system.

Maintenance and Long-Term Reliability


At AET, we understand that solar water heating systems require regular upkeep to ensure long-term performance. With flat plate collectors, however, maintenance is minimal compared to evacuated tubes. While evacuated tubes often need frequent part replacements due to their fragility, our flat plate collectors are built to last with fewer maintenance concerns. This makes AET systems a superior choice for those looking to reduce downtime and lower the overall cost of ownership.

By choosing AET, you not only get a more reliable and durable solar water heating system, but you also benefit from our expertise in system replacement. Whether you're currently using systems from Solar Skies, Caleffi, HTP, Oventrop, or evacuated tubes from Kingspan and Apricus, our direct replacement solutions ensure a smooth transition and an upgraded system that performs better and lasts longer.
