Solar Hot Water System
Using a Solar Hot Water (SHW) system is the most
efficient way to capture the sun’s energy to heat
water for use in your home or business. Small 1 or
2 panel systems are ideal for pre heating domestic
hot water. Larger systems of 4 panels or more can
be used to supplement in-floor heating or for pre
heating in commercial or industrial applications.
A SHW system consists of three main parts; panels,
storage tank and heat exchanger. There is also
a pump, piping and controls. The operation of a
SHW is fairly simple. The Photovoltaic (PV) panel
supplies power to the control system and pump.
When there is sufficient heat in the panels, the
circulating pump then pumps a glycol based fluid
from the heat exchange unit to the panels to pick
up the heat from the sun. The heated fluid is then
returned to the heat exchanger. The heat from the
fluid is then transferred passively to the storage
tank. The storage tank is supplied by cold water
from a well or city water. The heat from the heat
exchange unit heats the water in the storage tank.
The water in the storage tank can get up to 90C
in the summer months and even in winter the
temperature can be 40-50 C. The water from the
storage tank supplies the hot water tank with preheated
water, thus less energy is required to make
domestic hot water
