Hot Water Heat Pumps Reviews

When comparing hot water heating solutions, the use of heat pump water heaters has significant advantages. Heat pumps have been recognized by government agencies and consumer rights protection groups as one of the most effective forms of heating.

How do they work?

The heat pump is like a refrigerator that works in reverse, using the free heat extracted from the ambient air and then effectively transferring it to the water. Since electricity input does not generate heat, but only transfers free heat to water, their energy efficiency is very high compared to other forms of heating.

Their advantages:

1. Environmental protection

Since heat pumps use renewable energy (air), they are safer and cleaner to operate than fossil fuel burners, and can reduce carbon dioxide emissions by up to 70% (compared to gas and diesel burners).

2. Lowest operating cost

Due to its high energy efficiency, the operating cost of the hot water heat pump is extremely low, making it an ideal choice for swimming pool heating, floor heating and domestic hot water systems.

3. Security and control

Hot water heat pumps are equipped with a protection system to prevent damage in the event of failure.

Heat pump water heater specifications

Ambient temperature working range

The operating temperature range is -7 to 45 °C. When the ambient temperature is lower than 2 °C, the tank temperature reached may be lower. When the ambient temperature is high, the air supply fan will run at a lower speed.

Start protection

When the heat pump is powered on for the first time or is powered off and then restored, the unit will not start for three minutes. This is to protect the condenser.

Defrost function

The heat pump has a protection system that can stop the unit operation in the following situations: air inlet/outlet is blocked, the voltage exceeds the nominal range (207-255 V), the refrigerant system pressure is too high or the temperature is too high.

Maintenance costs

The heat pump system is simple to maintain and basically does not require annual inspection, and its service life is generally 20 years.

Noise

The heat pump does make a buzzing sound similar to an air conditioner when it is running. This may cause interference, depending on the location and how sensitive the occupants of the house are to sound, so this should be taken into consideration when deciding where to install the equipment.

Conclusion

For users who want to improve the efficiency and performance of hot water systems, heat pump water heaters are a good choice. They provide a quick return on investment and are three times more efficient than electric water heating systems.
