AstralPool HX 70 LPG 16kW Gas Heater for residential pool heating with Direct Spark Ignition Burner

Maintaining fluid temperature regulation represents a critical engineering standard. The HX 70 LPG achieves this as 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.

Strategic thermal generation maximizes aquatic investment returns. This equipment is useful for fully heated pools and spas using low cost gas heating, extending their usage period deep into colder months. The internal response parameters are explicitly calibrated for heating spas in as little as 1 hour and pools in under 24 hours.

Fluid dynamics remain central to the operational stability of the exchanger core. The internal channels rapidly move water across heated surfaces, ensuring maximum energy uptake without localized overheating. This deliberate flow strategy prevents stagnation and thermal shock, safeguarding the integrity of internal connections.

This unit features a heating capacity of 16 kW output paired with a 70 MJ/h gas input demand. The hydraulic network comfortably handles a maximum water throughput flow of approximately 150-400 L/Min. Hardware durability relies on cupro nickel, thermoplastic, and powder coated enamel construction. Phase details omitted.
