But choosing the right model and installing it correctly requires an experienced plumber who knows what they are doing.

Tankless Water Heater Installation FAQs


1. How long does installation take?

Most tankless installations take about one day, depending on the setup and any upgrades needed for gas or electrical lines.


2. Do I need a larger gas line for a tankless system?

Some homes do. We evaluate your current setup and let you know exactly what is required before we begin.


3. Will a tankless heater lower my utility bills?

Often yes. Tankless systems only heat water as you use it, which reduces energy waste and can lower monthly costs.


4. Can I replace my old tank heater with a tankless one?

Yes. Most homes can be upgraded to a tankless system with proper installation and adjustments.


5. How long do tankless water heaters last?

Many tankless systems last 15 to 20 years or more with regular maintenance.
