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.

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.
