Air To Water Heating System

Introduction to GENT fixed frequency air to water heating system

Air to water heating system is a heat pump unit that uses the heat in the air as the heating source, absorbs the heat in the air to prepare hot water. Combined with the indoor terminals and the hot water produced by the unit, the indoor space heating can be achieved. The thermo pump heating system is divided into two types: fixed frequency unit and variable frequency unit. This category mainly introduces the fixed frequency type.

What is a fixed frequency heat pump house heater?

The main difference between fixed frequency heaters and variable frequency heaters lies in the frequency at which the compressor in the unit runs. The compressor in the fixed frequency heatpump furnace runs at a fixed frequency. When the indoor temperature reaches the set value, the unit is completely shut down, and the unit restarts after the temperature drops. The operation mode of the fixed frequency Air Source Heat Pump Heating unit is a continuous cycle of "start-stop".

Unit advantages

1. Initial equipment investment can save 30~50%

2. Low maintenance cost (no risk of inverter module failure)

3. Suitable for areas with low electricity prices

4. Recommended for: intermittent heating scenarios (such as weekend villas), mild climate areas (areas with the lowest temperature in winter above -5℃)

Unit disadvantages

1. The compressor starts and stops many times, which increases power consumption and affects the service life of the unit.

2. The room temperature drops significantly during the winter defrosting period.

3. The COP of this heat pump heater is lower than that of the variable frequency unit.
