Save Energy With Low Standby Loss

Efficient PUR foam insulation minimizes heat loss to keep water hot and energy bills in check—validated by a standby loss of just 0.7 °F per hour.

Everyday Performance You Can Feel

A large 1⅜″ stainless coil that reaches the bottom of the tank helps deliver fast, even recovery for steady temperatures—up to a 238 GPH first-hour rating.

Built To Last—No Anode Required

High-grade stainless steel tank and coil resist corrosion and scale, maintain water quality, and eliminate sacrificial anode replacements over the tank’s life.

Installer-Friendly Layout

Standard NPT connections (1″ coil, ¾″ domestic and recirc) simplify piping. Compact 55½″ height and 25″ diameter fit tight mechanical rooms; tilt height eases moves.

Smart System Compatibility

Designed to pair with modulating, low-temperature boilers and suitable for multi-tank “battery” setups when higher DHW volumes are required.
