More Information

The Jandy Legacy LRZ 400,000 BTU natural gas heater is built for efficiency, durability and ease of use. Its electronic ignition automatically helps conserve gas by only lighting the pilot when heat is needed, and its copper heat exchanger and flo-thru baffles create a more efficient heat transfer for increased energy savings. Lightweight, non-corrosive polymer headers, a ceramic fiber combustion chamber and self-diagnostics mean this heater is built to stand the test of time.

The Legacy LRZ also boasts a number of advanced, user-friendly features, including a digital controller interface with an easy to operate menu and dual-thermostat control. The Legacy LRZ utilizes 2/2.5” CPVC universal union connections, 120VAC or 240VAC and can be installed outdoors or indoors, with proper ventilation.

Working at Forrest Hills Resort in Dahalonega Ga. I have had to start and run several of these, wow, what a great unit. Simple and lighter than others. Great recovery from 48 degree water and quite efficient.

Great product

Purchased this heater as direct replacement for an 18 year old Teledyne Laars ESC2 400k BTU unit that is almost identical. Delivery was only 3 days in a top quality crate! Setup was very simple since the old one had the same electrical (Aqualink RS6) and gas connections. I used a professional plumber to remove the old gas line and reconnect the new gas line and water lines. Overall we are very happy with Pool Supply World and this heater!
