Air source hot water unit and water heater both provide us with domestic hot water needs, but which one is more economical? It has become the biggest trouble for us to choose hot water unit. Let us introduce the operating costs between the two in detail. By comparing, we can clearly understand which one is more economical!
The air preheating pump unit uses electricity to drive the equipment, with a combustion value of 860KCAL/h, a thermal efficiency of 400%, and an energy demand of 11.6. The electricity cost of generating 1 ton of hot water per day is 9.28 kWh, and the monthly hot water operation cost is 278.4 yuan. The electricity cost of using the air source heat pump for one year is 3340.8 yuan.
The same electric energy is used to drive the equipment, and the combustion value is also 860kcal/h, so the thermal efficiency is 95%, and the energy demand is 48.9 kWh. The electricity cost of producing 1 ton of hot water is 39.12 kWh, and the electricity cost of producing hot water every month is 1173.6 yuan, so the total electricity cost per year is 14083.2 yuan.
From this, it can be seen that the thermal efficiency and energy demand of air source water heaters and water heaters are very different, and air source heat pumps are more energy-saving and power-saving, so it can be clearly seen that using air source heat pumps to produce hot water is the most effective and power-saving water heater unit.
