Heatpump Hot Water

Introduction to GENT heatpump hot water

Heatpump hot water is a type of water heater that uses the heat in the air as the heating source and heats water by absorbing the heat in the air, thereby achieving the purpose of supplying hot water or achieving building heating. There are two types of electric heat pump hot water heater: fixed frequency unit and inverter unit. This classification mainly refers to fixed frequency water heat pump heater.

What is a fixed frequency heat pump and water heater?

A fixed frequency water heater and heat pump refers to a heat pump water heater in which the compressor runs at a fixed frequency and controls the water temperature by "starting and stopping". In this type of heat pump water heater, the compressor has only two states: "full open" or "off". The unit stops running when the water temperature reaches the set temperature, and restarts when the water temperature fluctuates.

What are the advantages and disadvantages of fixed frequency dhw heat pump?

1. Advantages

â‘ Low cost: simple structure, affordable price

â‘¡Easy maintenance: mature technology, popular accessories

2. Disadvantages

â‘ High energy consumption: Frequent start and stop increase standby loss, and the long-term use cost may exceed the inverter unit.

â‘¡Noise problem: The noise is obvious when starting and stopping, and the impact is greater at night.

â‘¢Poor adaptability to low temperatures: Efficiency drops sharply below -5°C, and electric auxiliary heating is required (energy consumption increases dramatically)

What scenarios are suitable for fixed frequency heat pump boilers?

1. Low demand for hot water (such as single apartments, rental houses)

2. Hot water usage scenarios mainly in summer (low latitude areas)

3. Pursuit of low-cost one-time investment
