AstralPool HX 70 Nat 16kW Gas Heater for residential pool heating with Copper Fin Heat Exchanger

Managing intense aquatic thermal loads requires highly dependable equipment capable of rapid heat recovery. The HX 70 Nat is a pool & spa gas heater incorporating cupro nickel heat exchanger, an IV LCD digital thermostat, thermoplastic inlet/outlet headers, external gas connection, 45 degree high limit protection, electronic ignition system, powder coated enamel inside and out. Powder coated flue terminal.

Optimizing thermal transfer pathways ensures prolonged usability. The system is effective for fully heated pools and spas using low cost gas heating, extending their usage period significantly. Furthermore, its rapid thermodynamic response is highly capable for heating spas in as little as 1 hour and pools in under 24 hours.

Operating at peak efficiency requires an unrestrictive hydraulic architecture. The internal layout prevents restrictive pressure drops, allowing substantial water volume to absorb thermal energy directly. This sustained heat absorption prevents localized boiling points, actively extending the operational lifespan.

The system provides a heating capacity of 16 kW output powered by a 70 MJ/h gas input mechanism. It manages a maximum water throughput flow of approximately 150-400 L/Min. Constructed with durable cupro nickel, thermoplastic, and powder coated enamel. Electrical phase information is not available in provided sources.
