Approximately 10 to 15 percent of the electricity consumption of an average household is used by domestic heating circulators. The overwhelming majority of these consists of fixed three speed standard circulators.
The EU new Eco-Design Directive, the ErP-Directive EC 641/2009, starting 1st January 2013. The purpose is to reduce significantly the energy consumption. In 2015 these strict requirements will be enforced even more.
To date there was only the choice of purchasing an inexpensive inefficient standard circulator with high energy consumption, or selecting a modern high efficiency pump which was quite costly but very energy saving. The new Lowara Ecocirc® made by Xylem strikes the balance between these two options: a modern, electronically controlled high efficiency pump, which pays for itself within a short period of installation.
