State On-Demand Gas Water Heaters

• A comprehensive line of tankless water heaters.

• Designed for Residential or Commercial applications.

• Interior and Exterior installation options.

• Natural Gas or Propane.• Choose from 16 different

models.

1

The Durability of State

• Combines the durability of State and the convenience of continuous flow delivery.

• State’s On-Demand water heaters uses a high-fire burner to quickly raise the temperature of water passing through a copper heat exchanger.

• Since the burner is not ignited until there is a demand for hot water, it is highly energy efficient.

2

Technologically Advanced

• Continuous hot water up to 9.8 GPM (maximum flow rate)

• Natural gas or propane• Up to 237,000 maximum gas

consumption Btu/h• Energy efficient, up to 84% thermal

efficiency• Direct electronic ignition; no pilot light• On board diagnostics and safety

monitoring• Durable enough for 12-year limited

warranty on heat exchanger and 5-year warranty on all parts

3

Convenience and Control

• All models come with a Standard Remote Controller that can set the temperature within a specific range and can provide error codes to diagnose problems.

• The Commercial Remote Controller can be used to achieve temperatures above 140ºF, up to 160ºF for the 305 models and up to 185ºF for the 505 and 705 models.

Sizing

Model Selection Guide

• To properly size On-Demand units for a home, two factors are of critical importance . . .

1. Incoming ground water temperature

- Will determine the amount of “temperature rise” required to achieve the desired hot water outlet temperature (120ºF is recommended)

2. Peak hot water demand

- How much hot water the home will need during its busiest usage period

13

Ground Water Temperature Factor

14

Peak Hot Water Demand

• Consider all the applications and fixtures in the home that use hot water, including lavatory faucets, kitchen faucets, washing machines, dishwashers, showers and bathtubs.

• Determine how many of these appliances and fixtures will be in use at the same time during the busiest usage period.– For example, if one kitchen faucet, one shower and a washing

machine are all in use during the busiest period, use the number 3 to make your selection from the Model Selection Guide.
