Condensing gas tankless water heaters are very energy efficient so they can contribute to savings over time, despite a higher upfront price on the unit. Total installation costs vary depending on several specific factors, including venting requirements.

Because State water heaters are built for durability, a condensing gas water heater can last up to 20 years. Regular maintenance can help your water heater live a longer life as well. Other factors such as water quality and usage will also impact its lifetime.

A number of factors determine the condensing gas tankless water heater size that will work best for your needs. Some of these factors include the number of residents in your home, the types of appliances that will be using hot water, and the incoming groundwater temperature. To help you decide, you can talk through options with a local professional installer and consult State’s online XPERT™ Product Selector.

Yes. Boasting ENERGY STAR^® certification, condensing gas tankless water heaters are known for high efficiency. They also meet California’s strict emissions standards because they are designed for ultra-low NOx emissions.

Does a tankless water heater need a drain?
Discuss the need for a drain. Condensing gas tankless water heaters require a drain, while non-condensing models will not.

How do I keep my tankless water heater from freezing?
Freeze prevention is crucial. Ask your professional contractor about ways to avoid freezing. Though State tankless water heaters have freeze protection built in, heaters installed outdoors require draining water from the unit to prevent freezing during power outages. Putting these precautions in place can help you avoid damage to your unit.

Though the installation process is not complicated, we recommend hiring a licensed plumber or contractor. This is because the unit’s 15-year limited warranty is only valid if it is installed by a credentialed installer. Furthermore, proper installation and protection against improper gas line sizing and venting contribute to safety and performance. Professional installers will be able to ensure these factors are in place.

State’s condensing tankless water heaters boast some of the highest efficiency models for tankless water heaters. State condensing models have over 0.90 UEF (Uniform Energy Factor) and come with a 15-year limited warranty.
