In 2017 the existing photovoltaics was extended by another 18 kWp installation and a 10 kWh rechargeable battery. This figuratively makes the meter reader turn backwards.
In 2017 a air/water heat-pump system was amended to the existing oil-fired central heating.
This leads to a saving of appr. 8000 l heating oil per year. The energy needed to operate the heat pump is supplied by the roof top photovoltaics.
In 2014 the lighting of production hall and storage was reconditioned with LED tube devices. More light and a reduction of 50% energy cost are the benefit.
