Hot water represents the second
largest energy consumer in American households. A typical 80
gallon hot water heater will consume approximately 150 million
BTUs in its seven year lifetime. This will cost approximately
$3,500 at $0.08 per KW/H – not accounting for energy increases! If
you have invested in your house, your next investment should be in
solar hot water.
Why should I buy a solar hot water heating
system?
Your decision to buy a solar
hot water system is based on a variety of reasons. In some cases,
the primary consideration is to save money on water heating bills
by making an up-front investment. Other people want to include
environmentally friendly technologies in their home, or to help
reduce oil imports. Since adding solar hot water can increase hot
water delivery capacity, other people may buy a solar hot water
heater in order to meet the needs of a growing family. Businesses
may invest in solar hot water to demonstrate their commitment to
protecting our environment, or to limit uncertainty about future
fuel costs.
How much will my solar hot water heating
system save me?
The dollar savings produced by
a solar hot water heating system are directly tied to hot water
use, and avoided expenditures on conventional hot water fuels
(natural gas, LPG, oil, or electricity). Thus, the economic
benefits are higher for households with high water heating costs
(electricity) and with higher usage (households with three or more
residents). Generally speaking a solar hot water system will save
you up to 80% on your annual water heating bills.
How much will my solar hot water system
cost?
The total costs for a solar hot
water system vary according to a number of factors. These include
the type of system, the manufacturer, the installer, the size of
the system, and whether the system is being included in a new
construction project or installed as a retrofit to an existing
house. Approximate installed price ranges for closed loop,
household sized, solar hot water systems are:
1-3 persons: $4,000-$5,500
4-6 persons: $5,000-$6,500
Approximate prices shown are before tax credit or other incentive programs.
Are incentives available for solar hot water
systems?
Yes, The Oregon Department of
Energy has an incentive program that allows up to $1,500 in the
form of a tax credit for approved solar hot water systems.
Additionally check with your utility company to see if they have
any alternative energy programs to help reduce the initial costs
of solar hot water systems, and to promote the growth of renewable
energy use.
What are the environmental benefits from a
solar hot water heater?
Using the sun's clean renewable
energy to heat water is good for the environment because it
reduces several forms of air pollution and helps to reduce demand
for new and often environmentally threatening supplies for fossil
fuels. Most people in Oregon currently use fuel oil, electricity,
propane, or natural gas to heat their hot water. The environmental
impacts of using these fuels to heat water include global warming,
acid rain, urban smog, and the production of nuclear waste.
In Central Oregon, a new solar
hot water heater will typically provide up to eighty percent of a
household's needs. By installing a solar water heater, a family of
four, who currently use an electric water heater and consume an
average of 100 gallons of hot water per day, will prevent 4,250
pounds of greenhouse gas emissions each year. Another way to look
at it is that an emission reduction of this size is equivalent of
around 6,000 miles per year of pollution free driving (assuming
your car gets 25 miles per gallon). Either way, the environmental
contribution is significant (over 20 years it adds up to over 40
tons of emissions prevented) helping to reduce the threats of
global warming, and maintain the quality of life in Central
Oregon.
