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.
