Pump assemblies, the latest product line from HUMMEL HS, are compact, pre-assembled and insulated units comprising ball valves, mixer and pump, which can be quickly and easily assembled into the heating circuit at the construction site. They are available for conventional heating systems as well as solar heating systems. Use of this product dispenses with the need for complicated and time-consuming soldering or welding of the individual components. The customer is able to choose from different options that can be put together and assembled as required.

The robust insulation box is made out of EPP - it insulates the component parts and at the same time serves as transport protection. By using the manufacturer's optional mountable high-efficiency pumps, savings of up to €150 per year in energy costs can be made in a family home.
