Description

Technical Field

[0001] This utility model relates to the field of hot water supply technology, and in particular to a hot water supply device that combines a heat pump unit and an electric boiler. Background Technology

[0002] Hot water supply devices that combine heat pump units and electric boilers are typically used in high-efficiency, energy-saving hot water supply systems. These devices combine the high-efficiency heating capacity of heat pumps with the rapid heating characteristics of electric boilers, enabling optimal energy utilization under different operating conditions.

[0003] Currently, during prolonged use, the heating of hot water causes calcium and magnesium in the water to react and precipitate, resulting in limescale. The water flow at the connection point is relatively slow, which may cause limescale to accumulate. Over time, this accumulation not only reduces water flow but also corrodes the pipes, shortening their lifespan. Even after cleaning, the limescale will still flow backward with the water, making it impossible to completely remove it. Furthermore, the outflow of limescale will pollute water resources.
