Ask Us AnythingMost tankless water heater installations are completed in a single day. The exact time depends on your home's existing setup, gas line capacity, and whether any upgrades to venting or plumbing connections are needed. We give you a clear timeline before we start.
If your unit is under 8 years old and the issue is isolated, repair usually makes sense. If it's older, showing repeated problems, or failing to heat efficiently, replacement often costs less long-term. We'll give you an honest recommendation after a proper diagnosis.
Yes. JG Plumbing and Rooter is available 24 hours a day, every day of the week. If you have no hot water or a plumbing emergency, reach out and we'll get to you as quickly as possible.
Traditional water heaters keep a large tank of water heated continuously, even when you're not using it. Tankless systems heat water on demand, so you only use energy when hot water is actually flowing. This can reduce water heating costs significantly over time.
