Intelligent automation is the key to the Guardian Solar Water Heater’s outstanding efficiency and self-sufficiency. The Guardian Solar Water Heater will turn on and off daily, collecting heat whenever it is available. The automatic controller alerts the pump when to run. It also alerts the automatic check valve to open, simultaneously. The pump then circulates colder water (from the bottom of your special solar storage tank) through your solar collector(s), and returns the heated water to the tank. This cycle continues as long as sun is available to provide heat to your water. When there is no heat available, the controller turns the pump off, and closes the check valve to prevent any loss of heat from the tank,
Guardian Solar Water Heating kits have been manufacturing for more than 25 years. Solar water heaters can involve quite a number of components if constructed in a thorough manner. Guardian provides a simple solution to the complexity of these systems by packaging them in kits. The Guardian solar water heater illustrated above is a complete kit that includes all of the components (large and small) necessary to complete the perfect solar water heating system. But that’s not all! The Guardian solar water heating system also comes with many of the components already prefabricated which dramatically reduces the time necessary to install the system and virtually eliminates mistakes by the installing contractor.
Guardian has created the perfect solar water heater system. The system is self sufficient, needs no routine maintenance and provides the homeowner with 80-90% of their hot water needs FREE from the sun. On the days when the sun doesn’t provide all your hot water needs, the back-up electric heating element automatically turns on and ensures no loss in service.
The primary difference between the Guardian solar water heater and many others is that the Guardian solar water heater is an ‘active’ system. Many solar water heating systems are ‘passive’ systems. The differences in their total efficiencies are dramatic. Most passive solar water heating systems can only provide about 40-50% of the families average water heating needs. Passive systems act more like pre-heaters rather than self sufficient water heaters
