Although air energy water heaters ( heat pump water heaters ) are gradually rising in the market, air energy water heaters will inevitably cause some doubts and confusion for some users. The temperature of air source heat pump water heaters rises slowly and heats up for a long time. Similar user psychology will lay a question mark on the energy saving of air energy water heaters (heat pump water heaters). We have conducted rigorous tests. The results show that under such failures, the power consumed by heating is not much lower than that of traditional water heaters. Air energy water heater energy-saving effect is beyond doubt.

Why is it that the warming is slow and hot water is not enough? These issues we need to analyze troubleshooting from multiple aspects.

1. The unit installation position is not ventilated.

Troubleshooting method: re-adjust the host installation position or install exhaust fan exhaust.

2. The actual water consumption is much larger than the design water consumption.

Troubleshooting method: Every 1kg of domestic water rises by 1°C. Absorbing 1Kcal of heat is equivalent to 1.163×10-3KWh, and 1000Kg of water rises by 1 degree, and it needs to absorb 1.163 KWh of heat. If the daily water consumption exceeds the standard, we suggest that you look for the relevant manufacturers to redesign the hot water project and increase the number of hosts and tanks.

3. The machine refrigerant is too low, below the standard.

Troubleshooting method: Find out the reasons for less, add refrigerant according to the standard.

4. The exterior of the fin heat exchanger is too dirty, affecting heat exchange.

Troubleshooting method: This situation is also due to the lack of necessary maintenance work. The hair extension must be kept clean and free of contaminants such as fallen leaves, lint, and insects that can easily clog the cold fins to ensure efficient heat exchanger operation and maximum heat exchange. The solution to this situation is simple: clean the heat exchanger.

5. Heat exchanger fouling is serious.

Troubleshooting method: This kind of situation occurs in areas where the water quality is relatively hard, and the daily cleaning work of consumers has not been done. The solution is to clean the heat exchanger and remove scale. If the water quality in the area is too hard, water purification equipment may also be considered.

6. The unit is running too long.

Troubleshooting method: In this case, the general water quantity matching ratio is unreasonable. It is like a small horse-drawn cart. The unit cannot stop. The over-loading of the power distribution components and the increase of the water circulation volume caused by continuous operation of the unit for too long will be inevitable. Will lead to a series of system problems. It is proposed to increase the number of units and strengthen the power, and rationalize the ratio of tank capacity.

Omega as a professional manufacturer of solar and air-energy water heaters will consider these issues at the beginning of installation. And there are professional after-sales service personnel, so that customers feel comfortable buying, never worry about.
