The
Edwards solar hot water history began almost
50 years ago, when Edwards started producing hot water heaters in
1963. Over the years, they've built up a large, but select team
of Edwards Dealers around Australia. Not only is Edwards a major
Australian brand- they've become an international leader in the
production of solar hot water systems for both residential and commercial
applications, through providing customers with excellent design,
performance and reliability. Edwards offer you a range of technologies
to choose from.
Edwards Produce Three Styles
of Solar Hot Water
Close-coupled
system
The Edwards close-coupled solar hot water system is so named because
the tank is close to the collector plates. It uses what is called
the thermosiphon
effect- heat is collected in the flat plates, and then naturally
rises, into the storage tank.
This
ensures maximum efficiency- no pumps are requied to move the heat
between the collector plates and the storage tank.
Split
system
In this configuration. your Edwards solar hot water system is split
into two components. The collectors go on the roof, but the storage
tank is located (usually) on the ground.
This
is an ideal arrangement where your roof may not handle the weight
of a close-coupled system, or where aesthetics dictate the smallest.
most stylish profile on the roof possible.
Heat
pump system
There are many situations where either a close-coupled, or even
a split-system solar hot water system in not appropriate.
It
may be that there is no suitable, north-facing roof area. It may
be that the angle of the roof is too high. Perhaps the north-facing
roof is badly shaded. Perhaps you're in a heritage area, and aren't
allowed to put one on the roof. Maybe your partner just doesn't
want to see a solar hot water sytem on their roof. Whatever the
reason, a hea5t pump can be the answer.
Although
they don't use the direct, radiant heat of the sun, heat pump hot
water systems are treated as solar for the purpose of government
incentives.
In
fact, it's the sun that heats the air. All a heat pump does, is
to recover some of the heat that the sun has put in the atmosphere.
Putting 1kW of electricity into a heat pump, can give you as much
heat as it would require 4kW of electricity to produce.
Choose Which Edwards Solar
System Is Best For You.
As
you can see, there are three different styles of Edwards solar hot
water systems to choose from. But the choice doesn't stop there.
In the split system, you can choose between a gas-bossted, or electric-boost
system. In general, the gas-boosted systems are dearer to buy and
install, but cheaper to run- if you're on town gas. The more hot
water you use, the better you are off choosing the gas-boosted system.
