What it delivers

The Camplux CA422GNG 113,000 BTU Natural Gas Tankless Water Heater is a non-condensing gas tankless.

The listing doesn't state the BTU input, so its flow at your temperature rise can't be estimated from its own figures. The planner shows what your house needs.

Its exhaust runs hot, so the vent must be the material its manual lists, usually stainless; budget for the vent kit.

Listed details: connections: 3/4" npt; material: 102,000 BTU, 4.22 GPM, Gray; model: CA422GNG.

The listing gives dimensions of 13.86 in (W) x 23.9 in (H) and a weight of 26.5 lb.
