Heat your water using the sun
As much as 20 per cent of the energy con-
sumed in Canadian homes is used to keep
hot water flowing from the taps. A unique
way to reduce water -heating costs is by us-
ing the sun.
Solar systems can be used to supplement
or replace your existing water heater. Many
models also have a built-in, back-up heater
that can meet a household's hot water needs
when there is no sunshine.
The purchase and installation costs of
solar water -heating systems can be
recouped over time through lower energy
bills.
Solar heaters also offer a hedge against
inflation; prices for electricity, oil or gas
can vary but, after initial start-up costs,
energy from the sun is virtually free.
Solar energy technology
Solar water heaters work on a very simple
concept: collection, transfer and storage of
sunlight as heat. This process provides
homeowners with hot water, day and night,
for laundry, dish washing and bathing.
The collection of heat is based on the
greenhouse effect. Sunlight beams through
a clear glass or plastic cover and strikes a
dark, light -absorbing material that converts
the light into heat.
A car parked in the sun with the windows
rolled upillustrates this principle. The
sunlight passing through the windows
strikes the upholstery, which becomes hot.
This heat is then trapped inside the car by
the closed windows:
In the case of an operating solar collector,
temperatures can become extremely high,
. easily reaching 95°C.
Flat plate and evacuated tube collectors
are two commonly used solar water -heating
systems.
A flat plate collector consists of a shallow

The I1Ir:ltL mut in .1 ♦i'I.Ir Haler heater
can he culler ursttle ,lr outside thi building
rectangular box with a transparent glass or
plastic cover. Sunlight beaming through the
glass strikes a black plate or absorber that
is attached to a series of parallel tubes
through which fluid passes.
An evacuated tube collector consists of
several glass tubes, each containing a black
metal pipe through which the water passes
and is heated.
In order to ;reduce heat loss,. air is remov-
ed from the space between the pipe and the
glass, hence the term `evacuated'.
Depending on the design of the system, in-
sulated pipes transfer the heated water
from the collector to a storage tank or
directly to the point of use.
The third component of a solar hot water
system is an insulated storage tank. These
are generally larger than conventional
tanks, since sufficient hot water must be col-
lected during the day to meet evening and
early morning needs.
Installation
With careful planning, a solar hot water
system can be easily installed and presents
no inconvenience to the household.
The Most vinibie components of the
system - the out collectors - are attactively
finished and occupy a space of only 5 m' to
10 m2.

Ideally, collectors should face in a
southern direction to get maximum ex-
posure to the sun's rays. They can be install-
ed on an unshaded roof or wall, or mounted
on a special ground frame near the house.
Indoors, connecting pipes running from
the roof to the basement can usually be hid-
den from view in closets, walls and floors.
Selecting a system
Solar water heater dealers can provide in-
formation on current Canadian models;
help choose the best location for solar collec-
tors, piping connections and storage units;
provide detailed cost estimates; and, in
most cases, offer complete installation
services.
Before approaching a dealer, however,
become familiar with the types of solar
water heaters available on the market.
There is no evidence to suggest that any
one solar water heater design is significant-
ly better than another. You should begin,
therefore, by identifying the systems that
can meet your particular needs.
Your first important decision will be
whether to purchase a seasonal or year-
round system.
Seasonal solar water heaters can be used
only when the outside temperature is above
freezing. They tend to be less expensive
than systems designed for year-round use
because they do not require an expensive
freeze -protection mechanism.
Seasonal solar water heaters must be shut
down and drained when the temperature
drops below the low temperature rating
specified for the unit. They are particularly
attractive for families that spend a con-
siderable amount of time away from home
during the winter or that use relatively little
hot water.
Year-round water heaters are recom-
mended for families that use a lot of hot
water or remain at home for most of the
winter. These units usually provide more
solar hot water than seasonal heaters but
often at a higher cost.
Solar water heaters come in three stan-
dard sizes: 150 L/day, 225 L/day and 300
L/day. These numbers refer to the volume
of hot water the heaters are designed to
deliver on an average day, not maximum
daily outputs.
The amount of hot water used in your
home will depend on the number of oc-
cupants and appliances that use hot water,
such as dishwashers or automatic clothes
washers.
With help from a dealer, you should be
able to identify one or more suitable solar
water heaters that are available locally.
Preference should be given to models that
feature flow, pressure and temperature
gauges. Make sure that the necessary in-
stallation and operating information is sup-
plied and that you ,are familiar with the
system's maintenance requirements, war-
ranties and safe operating temperature.
Finally, the system should be accepted by
.the Canadian Solar Industries Association,
meet Canadian Standards Association stan-
dards and be installed by a technician
qualified by the CSIA.
Installation costs can be reduced if you
carry out some 'of the work yourself.
However, you will need some experience in
electrical, plumbing and carpentry work, as
well as some specialized knowledge on
mounting solar collectors, priming the col-
lector piping and installing control sensors,
among other things.
Do-it-yourself installations can also void
warranties and must meet local building,
electrical and plumbing regulations. •
Information on federal government solar
programs and lists of acceptable systems
can be obtained by calling toll free the Con-
servation and Renewable Energy Office in
your province.
If you cannot'locate a solar energy dealer
in your area, call or write the Canadian
