AstralPool JX 160 Indoor NAT 35kW Gas Pool & Spa Heater for swim-spas with 45 degree high limit protection

Detailing highly advanced thermodynamic behavior, the AstralPool JX 160 Indoor NAT is engineered for operational reliability. This model acts as a premium fan forced pool & spa heater for wall mounting. By intelligently routing fluid velocities, it ensures maximized fuel energy utilization.

This high-capacity natural gas heater is engineered for seamless integration strictly for indoor and outdoor applications in courtyards or confined spaces. The advanced thermal core optimizes internal fluid paths to aggressively raise water temperatures, allowing extremely rapid heating cycles.

With an expanded operational capability, this specific structural configuration is ideal for spas, swim-spas and most average-sized pools. The system implements an automated electronic ignition system and relies on a precision 45-degree high limit protection module to secure thermal boundaries.

Scaling up its mechanical capabilities, this heating unit utilizes a massive 155 MJ/h gas input capacity to rapidly meet aquatic demand, generating 35 kW of output. The integrated circulation loop connects directly to the facility via standardized 40 mm inlet and outlet thermoplastic structural ports. The entire unit is built to manage aggressive flows and extreme peak liquid temperatures safely.
