WHAT SIZE DO I NEED?
First estimate your hot water demand in gallons per day; use the chart below for an average figure (Note:
add 15 gallons per additional person or 20 gallons per additional room)
.
It varies widely with lifestyle (from
10 to 30 gallons or more per person) and with season (most people take longer and hotter showers in the
winter). For situations involving small families in
a large house, the number of bedrooms should be
considered in sizing a solar water heater. A system
sized to meet the needs of two people in a five
bedroom house today will likely be inadequate for a
family of five living in the same house tomorrow.

Next, choose a system from the following chart based on the gallons required. Note that multiple units
may be combined to achieve the total gallons desired. It is generally wise to slightly oversize the system
to help reduce backup requirements.
