An open loop water heating system provides many advantages. It is the simplest and typically the least expensive active system to install. There is no heat exchanger, which allows efficient heat transfer directly to the water. The system operates at standard line pressure. When there is not enough energy for sun, an electrical back up element will be automatically switched by controller.
