To make use of hydropower for individual house heating there is only one alternative and that is to use an air-conditioning unit. The electricity for the unit may, though, originate from different sources.
In case the building has access to a small water flow, like an old mill or irrigation dam, there might be a possibility to install a micro-sized hydropower generator. With luck, the micro-power station might even be integrated in old water-mills and hence contribute to the maintenance of cultural heritage.
With a micro-installation, delivering 230 V AC to the internal electricity installation in the building, i.e. "behind" the meter, the electricity produced will mainly be available in the house but any surplus will be delivered to the grid and discounted for.
Even a 10 kW generator, running only 8 h/day 200 days per year as may be the case in the smallest imaginable micro-installation will produce 16000 kWh per year which is enough for a normal single-family household and will fully compensate for the electricity used for climate control purposes.
The second option is simply to contract the delivery of hydropower to the building.
