Additional Information

How does QDD Solar's direct, integrated solar water heater system work?

Our solar water heaters use 3rd generation technology, maximizing efficiency up to 97%. Water heating is currently one of the most cost-effective ways to utilize the power of the sun.

This diagram shows how the solar vacuum tubes capture energy from the sun and heat the cool water at the bottom of the storage tank. Warm water naturally rises to the top of the tank and is then transferred through the pipe into your plumbing for use, combined with cold water at a mixing valve to control water temperature.

An optional QDD Solar Tempering Valve can also be installed (recommended) on the solar water heater system to regulate the temperature of water coming from the tank.

For commercial use (hotel, office building etc.), or pool, spa or hot tub heating, several solar water heater units and/or solar collector tubes can be connected together to provide high capacity water heating.

In this fashion, businesses can greatly reduce their electric bills and home owners can use their pool, spa or hot tub all year round. Please contact us to answer your questions on configuring a solar energy solution that is right for you.
