Solar Hot Water for Children's Sanatorium
in Odessa, Ukraine
In remembrance of the Chernobyl reactor disaster, this
project was intended to show people in Ukraine the sustainable energy
alternatives that would be feasible in their own
The conditions for exploiting solar energy are
very good, as the solar irradiation in the south Ukrainian Black Sea Coast
is 1650 kWh/m2 a year, 50% better than, e.g., in Austria.
Nevertheless, there is no commercial tradition of using solar energy in
The children's sanatorium in Odessa houses 160
radiation-injured children from Chernobyl region, with medical attendance, for
periods ranging from a month up to a year.
sanatorium lacks money to buy coal, the hot water supply was only heated once
per week during the summer. The heating equipment could be described as very
inefficient, with an aged, dilapidated, brick-construction coal-fired steam
boiler for hot water production, an uninsulated storage tank under the roof,
and a delivery system with hundreds of metres of uninsulated pipes.
The installation of the solar system was done jointly by
Austrian and Ukrainian NGOs in order to raise funds, to exchange
solar-technical know-how, and to achieve a practical implementation of the
installation. A consortium was funded between BLICK (NGO Odessa),
Sanatorium "Lustdorf" Odessa, ÖIE (Öster. Informationsdienst für
Entwicklungspolitik), FOE (Friends of the Earth), and AEE
(Arbeitsgemeinschaft Erneuerbare Energie).
The technical details of the solar installation:
- 48 m2 high selective strip collector
- collector field as roof-integrated wood construction
- transparent covering of collector by 4 mm security glass
- 5000 l hot-water storage tank with spiral heat exchanger
Materials, planning and design, transport, customs duties,
montage, and travelling expenses incurred a total cost of USD 40,000. To carry
these costs, the project was financed by private donors of different NGOs in
Austria, by private firms, and by Austrian governmental subsidies.
The next steps in the cooperative project with the children's
sanatorium will increase its energy efficiency by replacing the old boiler
with a smaller, new coal-fired boiler, insulating the delivery system, and
replacing the old armatures and fittings.
solar technology know-how will be passed along to Ukrainian NGOs (e.g., the
Austrian "Do-It-Yourself" construction system). A public information campaign
is also intended.
