Which of the direct heating and circulating heat pump water heaters is better for energy saving?
There are two heating methods for air source heat pump water heaters, which have always been direct heating, one is circulating heating. Many people do not understand the difference between the two. Leomon Technology introduces you to the kind of heating method that is more energy-efficient.Direct heating heat pump water heater:
The direct-heating heat pump water heater directly enters the main engine because the tap water pressure is greater than 2KG, without starting the booster pump, the tap water can be heated into the hot water storage tank through the condenser, and the working pressure and efficiency of the main engine are basically in a stable state.
Circulating heat pump water heater:
As long as the main engine of the heat pump water heater starts, the circulating water pump must work, which consumes more power than one pump. In addition, as the water temperature rises, the compressor discharge pressure increases and the heat exchange efficiency decreases. If the main engine stays above 45 degrees in the water tank for a long time The efficiency is significantly lower than that of direct heating units.
Circulating heating heat pump water heaters are mainly used for heat pumps with relatively large volumes. However, it is more economical and cost-effective to use direct heating heat pump water heaters for general civilian heat pumps. Hope this article can help you learn more about air source heat pumps.
