Question

How can many water-source heat pump systems be configured to supply hot domestic water?

1) by using de-superheating coils and water-circulating pumps built into many systems
2) by adjusting the load EWT and LWT levels to a higher temperature, which ensures enough water for heating and domestic use
3) by lengthening the evaporator coil and attaching it to an electric hot-water heater
4) by adjusting the power of the condenser and heat pump

Answer 1

Water-source heat pump systems can supply hot domestic water through the use of de-superheating coils and water-circulating pumps, adjusting temperature levels, or by attaching the evaporator coil to an electric hot-water heater.

Step-by-step explanation:

Water-Source Heat Pump Systems for Supplying Hot Domestic Water

Water-source heat pump systems can be configured to supply hot domestic water in several ways:

1. By using de-superheating coils and water-circulating pumps built into many systems. These coils and pumps help extract heat from the refrigerant and transfer it to the domestic water, providing hot water for domestic use.
2. By adjusting the load EWT (Entering Water Temperature) and LWT (Leaving Water Temperature) levels to a higher temperature. This ensures that enough water is available for both heating and domestic use.
3. By lengthening the evaporator coil and attaching it to an electric hot-water heater. This allows the heat pump system to provide hot water directly.

Adjusting the power of the condenser and heat pump is not a method used to supply hot domestic water.
