What it delivers

The Rinnai V53DeN Natural Gas Tankless Water Heater is a non-condensing gas tankless with a stated maximum flow of 5.3 GPM.

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.

From the listing: model: V53DeN.

The listing gives a weight of 33 lb.

Warranty, per the listing: Residential Factory Warranty - 120 months (heat exchanger), 12 months (labor), 60 months (parts).
