Solar Water Heating Store

Value System 4 has a 110 Volt circulator controlled by a Differential Controller with 2 sensors, and dual Digital Temperature readouts. It is for use in areas with Hard Freeze.

This closed loop system circulates a special Non-toxic Propelene Glycol Antifreeze solution through the collectors and then through the collectors and then thru a Heat Exchanger either in or attached to a storage tank. This system is available in several configurations to meet special needs.

In addition to the standard system which is set up to use a heat exchange tank like the Rheem|Rudd HE, special configurations using a "Power Rod" external heat exchanger are available. A special PV powered version of the "Power Rod" is also available. The "Power Rod" is easily connected to a standard water heater.

This system is a closed loop system with a traditional 110 volt pump and differential control like offered on many other sites. The big difference is that it is much easier to install and far more complete than systems offered on other sites. Our "Power Rod" External Heat Exchanger (PR) is a double wall Tube & Shell.
