PoolControls Zenheat ZHS17 Horizontal Airflow Inverter Pool Heater with R32 Refrigerant

Configured for residential pool and spa heating, the Zenheat ZHS 17 uses a full-inverter air-source heat pump system with R32 refrigerant and a titanium heat exchanger. Its DC inverter fan motor directs airflow horizontally, while automatic defrosting is provided through a 4-way valve. The heater operates from a 240V single-phase 50Hz power supply.

The ZHS 17 has a maximum power input of 2.60 kW and maximum current of 12 A, with a specified water flow volume of 5.5 m³/h. Its working temperature range is -15°C to 43°C, defining the temperature conditions specified for operation. The electrical and water-flow ratings provide the model-specific operating characteristics of this heater.

An ABS casing provides the stated enclosure construction, with an IPX4 waterproof level. Noise is rated at 43–55 dB(A) at 1 metre and 23–35 dB(A) at 10 metres. The ZHS 17 has a net weight of 54 kg and a gross weight of 65 kg, giving both the product and packaged weights for installation and handling considerations.

The net dimensions measure 925 × 364 × 642 mm, while package dimensions are 990 × 435 × 760 mm. The ZHS 17 therefore shares the stated net and package dimensions of the ZHS 13 while retaining its own model-specific electrical, flow and noise specifications.
