According to heat pump manufacturer Grundfos, the Grundfos Alpha2 is the most advanced energy efficient domestic circulator currently on the market. <br> <br> The Commission of European Communities EuP Directive states that from 2013 only A-rated glandless standalone circulators can be installed. <br> <br> The company says that its Grundfos A-rated Alpha2 circulator pumps use far less energy than typical (D-rated) pumps. With more than 120 million circulator pumps in Europe, an estimated 44 billion kW could be saved every year – the equivalent to the energy produced by five nuclear or ten conventional power plants. <br> <br> Grundfos says that with every Grundfos Alpha2 pump that is installed and D-rated pump that is upgraded, the home owner will not only save money but will also help conserve the planet. <br> <br> www.a-ratedpumps.co.uk or enter E0079 on the reader enquiry card
