Quality Of Materials Used In A Solar Heater..
Solar heaters can be used for a variety of purposes
like heating water, cooking, etc. The advantage it has
over electric geysers, for example: Electric geysers
consume more power and increase your bills. Power shut
downs make things more difficult. Solar heaters use
sunlight which is abundant and free and this saves precious
power.
Install a solar heater at slightly more
than the cost of an electric one and see the benefits
over a longer period of time.
The quality of heating equipment depends on: Quality
of materials used for the flat plate collector. It is
the collector which absorbs sunlight. See that the tubing
is made of copper, not mild steel. Mild steel will corrode
with time. The outer casing can be of glass fibre re-inforced
plastic and the frame should ideally be of aluminium.
The glass cover should have a transmitting strength
of atleast 85%. The storage tank should be five feet
or more above the heating system. Keep the tank insulated
to conserve heat, ideally with glass wool. An ideal
heating system should last for a minimum of 10 to 15
years. Preferably, use a simple design without many
accompanying gadgets. See that your solar heater is
also equipped with alternate electric heating options
(for use on overcast days or in winter).
Ensure that plumbing is properly done during installation.
The guarantee you get from the seller should cover at
least 10 years. Buy from a seller who gives prompt after
sales service. .
