SOLAR Water Heaters
Solar Water Heating
Hot water from the sun, in Ireland?
Is my house suitable?
Believe it or not, one square metre on your roof receives
the equivalent of more than 100 litres of oil in free solar
energy per year. As a matter of fact, this is more than in
Paris.
A solar water heater can suit most situations. All you
need is:
A solar water heater produces hot water by transforming
sunlight into heat through its solar panels. That heat is
then stored in a large hot water cylinder so that it is
available when you need it. A control system ensures
the regulation and safety of the whole equipment.
Simple, efficient and reliable!
➤ space to put the solar panels (generally on the roof)
and room for the storage cylinder in your utility
room or hot press.
➤ access to the sun for the panels (orientated between
south-east and south-west) and no over-shadowing
by trees or other buildings.

What to do next?
Ok. But what if the sun is not shining?
Quality is of paramount importance when choosing a solar
water heater and an installer.
No problem. A solar water heater not only converts
direct sunlight but also indirect sunlight into heat, so it
works even when the sky is overcast. True, there will be
less solar heat available during the winter, but a back-up
heater will boost the water temperature. The result is
100% comfort at all times, with plenty of hot water for a
fraction of the cost.
REIO’s recommendations:
• Only opt for a solar heating system with a recognised
certificate of quality and performance.
• Your system should be designed by a professional to meet
your specific requirements and fit in with your central
heating system.
What kind of system do I need?
There is a good selection of solar water heaters available
on the Irish market. They are all built on the same
principle, with varying degrees of sophistication and
price.

The table below gives a few pointers in terms of size and cost
of the equipment:
If you are building a new house or replacing your hot
water system,the extra cost of a solar water heater can be
as low as 1000 Euro compared to a conventional system.
• Your supplier should recommend an installer with the
proper training and experience in this field.
• Make sure your system has been thoroughly checked and
commissioned before signing off the installation.
