Wind-Powered Water Heating
for a Mountain Villa
near Sofia, Bulgaria
On Vitosha Mountain, at a remote rest villa owned by a
municipal company whose primary business is public park- and garden
maintenance, energy to heat space and water was in short supply. When the
power lines reached out to this area, the owners were faced with an unpleasant
surprise: high electricity prices.
Very windy conditions are common here. Grid electricity bills
to heat space and water would be extremely high.
This disadvantage turned to a benefit when it helped the
owners to qualify for an European-Union grant, a PHARE Programme
renewable-energy demonstration project.
Publicly supported maintenance was arranged, and a wind
turbine was installed on a windswept clearing near the villa. It provides
enough electricity to power a heat-accumulating electric stove and a hot-water
tank. In this way, thousands of kilowatt-hours are saved every month; the
exact amount varies according to the season.
