SOLAR WATER HEATING WITH ELECTRIC BACKUP FUNDAMENTALS

The solar heating system puts the most amount of heat into the storage tank when the bottom of the tank is cool. That is where the internal heat exchanger is located. This allows the collector temperature to be lower and still transfer heat into the storage tank.

When hot water is taken from the top of the tank, cool water is delivered to the tank bottom by means of a diptube. The thermostat to turn on the lower heating element is located above the internal heat exchanger’s level to ensure that the heat exchanger stays in a cool zone unless backup heat is needed. If the lower heating element thermostat is activated, this is an indication that there is not enough solar heating available to meet the immediate need. Approximately 1/3 of the storage tank volume needs to be removed without sufficient solar heating for the lower element to energize.

The typical solar water heater with electric backup has only one element. In periods were solar heating is not available the amount of stored hot water is about ¼ of the tank volume. The dual electric element backup will allow the entire storage tank to hold hot water during these periods. The unique design promotes solar heating yet does not compromise heater performance when it is not available.

The amount of heat transferred into the tank due to solar heating is inconsistent. The more heat stored in the tank through solar heating, the lower the operating costs. The integrated mixing device must be installed to ensure that if higher temperatures are achieved, safe water temperature delivery occurs. It is recommended that storage tank temperatures are not allowed above 185°F. Temperature levels above that point may activate the electric backup emergency cutoff device, disconnecting the electric backup system.

Solar Water Heater specifications

Bradford-White Corp is a well-known name in the water heater industry, and among its innovative offerings is the Solar Water Heater, a solution that combines sustainability with performance. As consumers increasingly seek energy-efficient alternatives, Bradford-White has successfully positioned itself as a leader in solar technology.

One of the key features of the Bradford-White Solar Water Heater is its ability to harness energy from the sun to provide hot water. This system uses solar collectors that capture sunlight and convert it into thermal energy. The solar collectors can be roof-mounted or ground-mounted, making them adaptable to various property designs. They are typically made with durable materials designed to withstand harsh weather conditions, ensuring longevity and consistent performance.

The technology behind Bradford-White's solar water heating system includes a closed-loop system that circulates a heat transfer fluid through the solar collectors. This fluid absorbs heat and is pumped to a storage tank where heat exchangers transfer the energy to the water. This means that even on cloudy days, the system can still deliver energy-efficient hot water.

Another characteristic of Bradford-White solar water heaters is their compatibility with conventional water heating systems. This means that they can be installed as a stand-alone system or as a supplementary component to existing water heating units, offering flexibility depending on household needs and preferences. The integration of solar technology not only reduces energy bills but also lowers greenhouse gas emissions, making it an environmentally friendly choice.

Moreover, these systems are designed with user-friendly controls, enabling homeowners to monitor and optimize their hot water usage effortlessly. The advanced controls often come with features such as programmable settings, allowing users to take full advantage of solar energy during peak sunlight hours.

Bradford-White also prioritizes safety and efficiency in its solar water heaters. The systems are equipped with various safety features, including pressure relief valves and freeze protection measures to prevent damage in colder climates. The energy efficiency ratings are impressive, often exceeding industry standards and providing consumers with peace of mind regarding their investment.

In conclusion, Bradford-White Corp's Solar Water Heater presents an innovative solution for reducing energy costs while promoting sustainability. With advanced solar technology, durable construction, and user-friendly features, this system is an excellent choice for environmentally conscious consumers seeking reliable hot water solutions.
