Description of product
This shows a typical solar system and how it
interconnects to your existing heating system. It can
Generate up to 70% of your hot water requirements for
FREE!
WHAT IS SOLAR THERMAL?
Solar Thermal is a clean and highly efficient means of
using renewable energy from the sun to provide the hot
water used in the home. The basic principle is easy to
understand. If you unroll a garden hose on the ground
and leave it exposed to the radiant heat of the sun, in
a short time the water in the hose will become warm.
Solar thermal collectors work in very much the same way,
only more efficiently. Usually, but not exclusively,
roof mounted solar collectors will be connected to one
of the coils of a twin-coil cylinder using a sealed
circuit containing a special glycol/water solution. This
fluid not only withstands the high temperatures in
excess of 200ºC on a summer day but also will not freeze
in temperatures down to –25ºC. The pump in the system
circulates the heated fluid from the panel to the
cylinder where the heat is transferred to the stored
water through the lower coil.
WHY INSTALL SOLAR THERMAL?
Solar thermal technology is the most reliable, efficient
and accessible form of renewable energy available today
and when combined with Grant's high-efficiency Vortex
Condensing Boiler, annual fuel bills can be dramatically
reduced. As solar water heating depends on radiation,
not direct sunlight, it even works on dull days.
Installing Grant Solar collectors can help reduce
heating bills by providing up to 70% of a household's
domestic hot water requirements per annum. Solar thermal
is also great for the environment, as it has no
emissions and is assured for the next 4 billion years.
DOESN'T SOLAR EQUIPMENT SPOIL THE LOOK OF A HOUSE?
Grant have developed flatter and less obtrusive panels,
which are available in two colours - silver, for a more
contemporary look, and bronze which blends with most
roof types on domestic dwellings. These two options
ensure maximum architectural design flexibility. There
are various mounting options for the panels, so siting
should not present any problems.
WHY CHOOSE GRANT SOLAR?
Installing a Grant Solar Thermal system has many
advantages for the homeowner. Apart from reducing the
amount of fossil fuels used, and the resultant savings
in annual fuel bills, the reduction in harmful emissions
will help reduce the long-term effects on the Earths
climate. For the installer, the Grant system has some
unique installation features. The Solar pump station
incorporates an air eliminator system that allows the
system to be both filled and purged of air in a single
operation. Unlike other arrangements there is no need to
install an air vent outside on the roof and also no need
for regular maintenance. The Grant Solar collectors are
the ‘Flat Plate’ type using 4mm thick ‘low Iron’ glass
and a copper collector panel which has a special
selective coating. This construction maximises solar
absorption whilst minimising reflection by up to 95%.
Grant Solar collectors can be installed on sloping roofs
using either an on-roof or in-roof mounting system and
also on flat roofs if required. For ease the Grant Solar
Thermal System can be ordered as a complete kit
comprising of the collectors, roof-mounting system, pump
station, expansion vessel, solar controller, pipe
connections and solar fluid. Grant Solar systems
integrate easily with conventional water heating systems
and will typically only take a couple of days to
install.
