Tankless Water Heater Details
Frequently Asked Questions
How does a tankless water heater work?
A tankless water heater heats water on demand rather than storing it. When you turn on the tap, cold water flows through the unit and is instantly heated — giving you an endless supply of hot water without the need for a bulky tank.
Is a tankless water heater really more energy-efficient?
Yes. Because it only heats water when needed, a tankless system can be up to 30% more efficient than a traditional tank — helping reduce your energy bills over time.
How long does installation take?
Most installations are completed in one day. We remove your old tank, install the new system, and test everything to ensure it’s working perfectly — all in a single visit.
Is Step Up Plumbing licensed and insured?
Yes! Step Up Plumbing is fully licensed, bonded, and insured. You can have peace of mind knowing your installation is handled by professionals who meet all local and state requirements. We take your home and safety seriously — no shortcuts, ever.
What size tankless water heater do I need?
It depends on the size of your home and how many bathrooms you have. Don’t worry — we’ll assess your needs and recommend the best system to ensure consistent hot water flow.
What’s included in the installation price?
Our pricing includes:
- Removal of your old tank
- Labor, parts and tax
- Guaranteed set price, no hidden fees.
What’s the lifespan of a tankless water heater?
With proper maintenance, a tankless unit can last 20+ years — nearly double the lifespan of a traditional water heater. A regular tank in Arizona lasts only 8-10 years.
Plus, Navien Tankless has a 15 year warranty. While Regular Tank Heaters only have 6 years and a decreasing prorated policy.
Do tankless water heaters require maintenance?
Yes, it’s recommended to flush the system annually to prevent mineral buildup. We offer affordable maintenance plans and can guide you through the process.
What happens if I go away for the summer or a long vacation?
Perfect for snowbirds! Tankless systems are less prone to flooding, and some models have built-in timers and recirculation features for low-maintenance efficiency while you’re away.
What warranty is included with Navien tankless water heaters?
The warranty on tankless water heaters are good for 15 years, and regular tank heaters have a pro-rated warranty that decreases in value over the course of 6 years.

We service the majority of the towns in Arizona including: Mesa, Gilbert, Chandler, Paradise Valley, Scottsdale, and surrounding areas
