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.
