Rheem RS80-42BP, RS47-21BP installation instructions Keep the use of the Backup Heater to a Minimum

While your system is one of the most efficient available, there are two simple steps you can take to increase your water-heating cost savings.

Keep the use of the Backup Heater to a Minimum

You can save the most money on your water-heating bills by using the backup heater on your system as little as possible. If the sun shines brightly between I0 am and 3 pm, enough heat will normally be generated to keep the water hot throughout the rest of the day and night.

However, on days when the sky is cloudy or when large quantities of hot water are being used, we suggest that the backup heater be left “ON” overnight to ensure adequate hot water the next morning.

Try to use Hot Water during Daylight Hours

When possible, schedule heavy hot water use, such as dish washing, laundry and showers, in the middle of the day. If hot water usage occurs while the sun is up, the fresh (cold) water added to the storage tank is heated more quickly.

When water is used late in the day or at night, the fresh water entering the tank will be heated by the

element so hot water is available in the morning.

The Rheem Thermosiphon systems operate on the passive thermosiphon principle a ‘closed loop’ to provide fail-safe freeze protection up to -30°F of the collector closed loop. The closed loop consists of the solar absorbers, a single wall heat exchanger around the outside of the storage tank, and plumbing attachments.

Radiant energy from the sun heats the special long- life fluid in the solar collectors. As the fluid is heated, it rises into the tank heat exchanger and heats the potable water stored within.The hot potable water is stored in a well-insulated steel storage tank, which is lined with two coats of Primaglaze vitreous enamel for high temperature stability.

Flow of the closed loop fluid, using the passive thermosiphon principle, is accomplished without pumps, sensors or moving parts.
