Continuous Hot Water for Your Home
A traditional water heater stores a limited supply of hot water. The Adapt®+ from State Water Heaters heats water on demand, allowing your household to enjoy long showers and back-to-back hot water use without waiting for a tank to refill.
This 199,000 BTU model can provide up to 10.5 gallons of hot water per minute under ideal conditions. Actual output depends on incoming water temperature, your temperature setting, and how many fixtures are used at once.

Faster, More Efficient Hot Water
The built-in recirculation pump can reduce how long you wait for hot water to reach your fixtures. Its performance depends on your plumbing layout and whether compatible return plumbing is available.
The Adapt®+ also reduces the standby energy loss associated with keeping a tank of water hot. Its condensing design captures heat from the exhaust and uses it to help heat your water, contributing to its 0.95 Uniform Energy Factor.
Protection Against Mineral Buildup
Water minerals can build up in a tankless water heater and reduce heat transfer. X3® Scale Prevention Technology helps prevent minerals from bonding to the heat exchanger, supporting consistent performance and longer system life.
State says X3® technology can extend heat exchanger life up to three times compared with an unprotected unit.
Control Your Water Heater With the iCOMM™ App
The State Adapt®+ works with the iCOMM™ Connectivity App, giving you access to available water heater settings from a compatible smartphone or tablet. Depending on the system setup and installed accessories, the app can help you:
- Check operating status
- Monitor and adjust temperature settings
- Manage recirculation schedules
- Change available operating modes
- Receive system alerts and diagnostic notifications
The app is available for Apple and Android devices. Learn more about the iCOMM™ Connectivity App from State Water Heaters.
Is the State Adapt®+ Right for Your Home?
Tankless water heaters must be sized for the amount of hot water your household uses at one time. Our plumbers evaluate your household size, number of bathrooms, incoming groundwater temperature, fixture flow rates, gas supply, venting, and plumbing layout before recommending installation.
Ohio’s colder groundwater can reduce a tankless water heater’s output because the system must work harder to reach your desired temperature. As a locally owned company, our plumbers understand these regional conditions and can help determine whether the State Adapt®+ is the right fit for your home’s hot water needs.
Professional State Tankless Water Heater Installation
Installing a tankless water heater may require changes to the gas supply, venting, water lines, electrical connection, and condensate drainage. Our licensed and insured plumbers inspect your current setup, remove the existing water heater, install and test the Adapt®+, and explain its controls and maintenance requirements.
The wall-mounted system supports natural gas or liquid propane, along with flexible venting options based on the home’s requirements.
Warranty and Financing Options
The State Adapt®+ STHR-199X3 100 includes a 15-year limited heat exchanger warranty and a 5-year limited parts warranty. When we install your new tankless water heater, our local plumbing team registers the applicable warranties for you.
