Which of the direct heating hot water heat pump or the circulating hot water heat pump produces higher hot water?The direct heating hot water heat pump can produce hot water at any time, the water temperature is constant, the hot water is provided at a constant temperature 24 hours a day, and the unit can be started to make up hot water at any time.
Circulating hot water heat pumps can also meet 24 hours constant temperature water supply, but the system is complicated and the installation and construction are difficult. In a large project with multiple units and multiple water tanks, indirect heating can be used to achieve the same effect, but the cost is significantly higher. High, the point of failure increases. Do not replenish water during water use and do not work.
If the circulating hot water heat pump uses water for 6 hours a day, it means that the direct heating hot water heat pump can work 6 hours longer than the circulating machine, which means 25% more hot water.
The direct heating hot water heat pump produces hot water more efficiently. But the relative cost is higher than the circulating hot water heat pump. Generally, commercial hot water heat pumps choose direct heating hot water heat pumps. Although the cost is relatively high. However, the direct heating hot water heat pump is more convenient and more efficient in later use.
