Residential Solar Hot
Water Systems
The principles of solar hot water heating are very simple.
Collector tubes absorb the heat
from the sun and transfer it to the water or other liquid flowing through the tubes, in the same way that water in a garden
hose will heat up if left lying in the sun.

Let's look at the components of your hot water system and how they work.
Your system is made up of:
Solar
Collectors
A well insulated storage tank with a heat exchanger
Regusol unit: A circulating pump and control
unit
Depending on the size of your family and your particular hot water requirements, you will need either one or two
solar collectors.

HOW YOU BENEFIT FROM YOUR
SYSTEM
Heating water in your home is one of the most energy consuming
demands you have. The cost to heat water in your home is likely to be 25 - 30% of your total energy costs; it will
be higher if you have more than four people in your home. This may mean that almost half of your electric bill, or more than
40% of your gas or oil bill, will go towards your domestic hot water costs. Solar water heating is the easiest, most straight-forward
way to use the sun to save both energy and money. A residential solar hot water system will reduce the energy you require
to heat your hot water anywhere from 60 to 80%.

Federal and State Incentives and Credits
Your Investment
Your system is a long-term investment that will provide
Free hot water, or
greatly reduced utility bills, saving you $100s annually this can be even more significant if your utility company has
a tiered rate structure, charging more at higher levels of usage.
Protection against increased energy prices
once installed your system will be producing all or some of your hot water at no cost.
The use of clean, non-polluting
renewable energy it is estimated that, over a 20 year period, a solar hot water system that replaces an electric system
will avoid 50 tons of carbon dioxide emissions. Carbon dioxide traps heat, contributing to the global warming. You are contributing
to the reduced dependence on fossil fuels.
