Thanks to their "full inverter" technology, Mr. Silence heat pumps deliver optimum heating results for your pond or swimming pond despite low energy costs. When conventional heat pumps run at full power, the Mr. Silence Inverter heat pump uses inverter technology to efficiently adapt to the temperature fluctuations of the water and your environment. In this way, the heat pump maintains the water temperature with little energy. In addition to energy and cost savings, Mr Silence inverter heat pumps offer more stable performance with less noise than conventional inverter heat pumps. These are usually step inverters, which are less energy efficient.
