Lowara Circulating Central Heating Pump 4m Head - Energy Efficient

Approximately 10-15% of the average household electricity consumption 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 is to significantly reduce household energy consumption. In 2015 these strict requirements will be enforced even more.

The new Lowara Ecocirc variable speed, modern, electronically controlled highefficiency pump, will pay for itself within a short period of installation.  Concentrating on the basics - reliable high efficiency and maximum payback, this pump already complies with the ErP directive of 2015. 

The Lowara Ecocirc highefficiency pumps have ECM-technology and permanent magnet rotor for applications such as:

  • Domestic Central heating (one- and two pipe systems)
  • Underfloor and surface heating
