Frequently asked questions

• How to choose the right pump performance/head? It must cover the pressure losses in your specific circuit (pipe length, number of fittings) - if in doubt, consult a heating engineer who will accurately dimension the pump for you.
• Must the installation be carried out by a professional? Mounting the pump into a prepared pipe can be done by a DIY enthusiast, but we recommend that the electrical connection and system adjustment be checked by a professional.
