Selection Criteria Circulation Pumps
Topten (Best products of Europe) presents the most energy efficient circulation pumps for heating systems of Europe.In order to be selected, pumps must comply with the following criteria:
Order of presentation
The products are ranked according to their flow rate. The order of presentation can be changed by clicking on the headings of the tables.
Brand and Model
Brand and Model name with link to the producer.
Energy efficiency index
Energy efficiency index (EEI) according to the Ecodesign regulation for circulators No 641/2009. A lower EEI indicates higher efficiency.
Flow rate (m3/h)
Flow rate at maximum hydraulic power (where Q*H is maximum, according to EU regulation No 641/2009). The flow rate is the primary criteria for dimensioning a pump. Well insulated single family houses require less than 0.5 m3/h - most pumps are too large for that. Older houses (up to four-family houses) need 1 to 2 m3/h.
Delivery head of the pump (where Q*H is maximum, according to EU regulation No 641/2009).
Maximum power input (W)
According to the data sheet. Speed controlled class A pumps usually run at much lower power.
Electricity consumption (kWh/period)
Electricity consumption in kWh during a 8-month heating period (5000 hrs operation).
This item displays the availability of models in European countries according to producers’ declarations and national Topten sites. "EU" means all countries of the European Union. However, the availability is sometimes difficult to define precisely depending on retailers' selling decisions or if the supply is stated as possible on catalogues but there is no marketing for specific products in some countries.
EU regulation No 641/2009 on Ecodesign requirements for circulators, July 2009.
Regulation No 622/2012 amending regulation No 641/2009, July 2012.
Coolproducts informs about the EU ecodesign process. It is a coalition of NGOs' campaign for a stronger, fast Ecodesign Directive to save the climate and money.
