Domestic circulation pump for the circulation of hot water in family homes inhabited by one or two families and for use in small heating, cooling, and air conditioning systems. It is suitable for lead-free drinking water up to a temperature of 90 °C. The pump is driven by a single-phase motor with permanent magnets and is equipped with a digital timer suitable for domestic systems with hot water tanks or systems with plate heat exchangers for water heating. The timer monitors and controls the operation of the pump to ensure energy costs are as low as possible. Continuous operation of the pump can be set as needed so that the pump starts at any time, or to ensure 24-hour shower and tap water availability.
