SOLAR
POWERED HOT WATER SYSTEMS
Insulation Services are proud to announce the arrival of:
‘Solar Powered Hot Water Systems’
|
|
 |
| Using
‘Evacuated tube panels’ which have been designed to capture
light energy from the sun to convert it to heat, so they
work even on overcast days. The construction of the tube is
very like a thermos flask. Two glass tubes are sealed with a
vacuum between them. The inside of the inner tuber is
treated with a heat absorbing coating. Light passes through
the glass and is converted to heat when it meets the
coating. |
| The panels
have a sealed copper file, which runs down the middle of the
glass tube. This file contains a liquid, which is boiled by
the heat inside the tube. The liquid condenses in a bulb at
the top and therefore releases heat. The bulb can reach
incredible temperatures, well over 220 degrees centigrade
and hot enough to melt solder on! |
 |
| Some
frequently asked questions regarding Solar. |
| Does solar
water heating significantly reduce fuel bills and the use of
energy?
A correctly
sized solar water heating system will provide roughly half
your annual demand for hot water. You should enjoy your
first ‘free’ hot bath around late March each year. |
 |
| Will solar
water heating run central heating?
Sadly not. On a
pleasant day in winter solar water heating will still help
to heat your water, but there is just not sufficient energy
in the sun to heat your house throughout the year. |
| Do flat
panels and evacuated tube panels provide the same heat?
On a bright
sunny day, a flat plate and an evacuated tube panel will
produce a similar amount of hot water, but on more overcast
days, which make up the majority of the UK climate, an
evacuated tube panel will provide far more heat and will
greatly extend the effective water heating season. |
 |
| Will I ever
get my investment back?
The payback on
a solar water heating system totally depends on what you
have paid and what is installed. An evacuated tube system
installed at a reasonable price should quickly pay for
itself. |
