Here at Eco Plumbers, we are consistently working to bring you and your
family more environmentally friendly solutions for your home plumbing
system. Solar energy plumbing solutions are one way to ensure that your
plumbing system is not only good for the environment, but also good for
your wallet. With a solar water heating system, you can heat water more
efficiently using energy from the sun. Read on to learn more about the
variety of options available for solar water heating systems as well as
why solar energy is the right choice for you.
Solar Water Heating Collector Types
Solar water heaters are divided into two parts - the circulation system
and the collector. When choosing your solar water heater, you have three
collector options available:
Flat-Plate Collector: A flat plate collector consists of a box that is both weatherproofed and
insulated. The box contains copper tubes and an absorber plate. This type
of collector can generally hold about 40 gallons of water.
Integrated Collector-Storage: Also referred to as a batch collector, the integrated collector-storage
system consists of an insulated box that contains multiple black tanks
or tubes. First, water is heated in the solar collector, and second, the
water moves into the conventional water heater, which is used for backup.
This type of collector is generally not suited to very cold climates.
Evacuated-Tube Collector: The evacuated-tube collector is the most efficient type available, and
it is typically used in commercial applications. This collector contains
transparent glass tubes that act similarly to a thermos, trapping in heat.
Solar Water Heating Circulation Systems
When it comes to the circulation system for your solar water heater, you
have a choice between an active or a passive system. While active systems
use circulating controls and pumps, passive systems do not. Active systems
can be either direct or indirect; direct systems are best suited to climates
in which freezing is rare, while indirect systems work well in areas prone
Passive systems come in two types: integrated collector-storage and thermosyphon.
Integrated collector-storage systems are best for warmer climates and
for households in which hot water is most necessary in the daytime and
evening. Thermosyphon systems involve warm water rising and cooler water
sinking as it passes through. They tend to be more expensive and have
very heavy storage tanks, but they are also very reliable.
Why Solar Energy?
Although many solar water heaters are initially more expensive to install
than conventional water heaters, they offer major savings over time. With
solar energy, the average household can cut its energy costs for water
heating by 50%-80%. You can use the tools available on
energy.gov to determine how much you will save by installing a solar water heater.
Because solar energy is free, you will also remain safe from rising fuel
costs as well as fuel shortages. Furthermore, those who install a solar
energy system are eligible for a federal income tax deduction, allowing
