Frequently Asked Questions

How do I choose the right pump output/head? It must cover the pressure losses of your specific circuit (pipe length, number of fittings) - if in doubt, consult a heating engineer who can size the pump precisely for you.
Must installation be carried out by a professional? Fitting the pump into a prepared pipe run can be handled by a handy homeowner; we recommend having the electrical connection and system balancing checked by a professional.
