What Customers Say
Tankless heaters heat water only when a tap opens, so they don't run out the way a tank does. They need more gas than most tanks, a proper vent route and protection from hard water. Get those three right and a tankless unit is a solid long-term upgrade.
Most tankless problems start at installation, not with the heater. An undersized gas line, a poor vent run or no way to flush the unit will cause trouble later. We plan those details before the old tank comes out.
When to Call About Tankless Water Heater Installation
- Back-to-back showers drain a tank. A properly sized tankless unit keeps up as long as it is fed enough gas.
- Replacement time is the natural moment to compare tank and tankless for your home.
- A wall-mounted unit frees the floor space a tank takes up.
- Scale in the heat exchanger or a gas supply issue are common causes worth checking.
- Often a sign the unit is scaled up, undersized or short on gas.
- More fixtures change the hot water demand, so the heater choice should be part of the plan.

How Tankless Water Heater Installation Works With Renova
Step 1: Check the gas supply
We confirm the gas line can deliver what the unit needs. Many tank-era lines are too small for tankless.
Step 2: Plan the venting
We find a safe, code-compliant vent route through the wall or roof for the model you choose.
Step 3: Protect against hard water
Isolation valves are installed so the heat exchanger can be flushed. We explain whether softening makes sense.
Step 4: Mount and connect
The unit is mounted, piped in copper or approved material, connected to gas and power, and leak-tested.
Step 5: Fire it up and walk through
We set the temperature, run every fixture and show you the controls and the flush valves.

Tankless Water Heater Installation in the East Valley
Hard water is the biggest threat to a tankless heater in the East Valley. Minerals coat the heat exchanger, which cuts efficiency and triggers error codes. Regular flushing through the isolation valves keeps it clear, and a softener slows the buildup.
We have installed tankless heaters in laundry rooms, garages and exterior closets, including homes in Tempe. The right spot depends on your gas line, the vent route and where the hot water is used most.
Tankless Water Heater Installation by City
Common Questions
- Is a tankless water heater worth it in Arizona?
- For many households, yes, especially families that run out of hot water. The catch is hard water, which scales the heat exchanger, and gas supply, which is often too small in homes built for a tank. With proper gas sizing, venting and regular flushing, tankless works well here.
- Who installs tankless water heaters in the East Valley?
- Renova Plumbing & Drain installs tankless water heaters in Gilbert, Chandler, Mesa, Queen Creek, Tempe and Scottsdale. Renova checks the gas supply, venting route and water hardness first, then installs the unit with flush valves so it can be maintained properly.
- How often should a tankless water heater be flushed?
- With East Valley hard water, flushing about once a year is a common starting point, and more often if the water is very hard or there is no softener. Flushing runs a descaling solution through the heat exchanger using the isolation valves installed with the unit.
Frequently Asked Questions
Sometimes, but often not. Tankless units burn much more gas at full output than a tank heater. Many homes built for a tank have a line that is too small. We measure the run and the load before recommending tankless, and explain what upsizing would involve if it is needed.
A properly sized unit heats water as long as a tap is open, so it will not run out the way a tank does. The limit is flow. If several showers and appliances run at once, the unit must be sized for that. We size it to how your household actually uses water.
Minerals in hard water coat the heat exchanger over time. That reduces efficiency, causes temperature swings and can trigger error codes. Every install gets isolation valves for flushing. We also explain whether a water softener makes sense for your household, without pushing one.
Replacing an existing tankless unit usually takes several hours. Converting from a tank typically takes about a day, because it often needs new venting and gas line work. You get the expected timeline before work begins, and we tell you straight away if something unexpected turns up.
Usually, since it involves gas, venting and water heating. Permit rules come from your city, so check with Gilbert, Chandler, Mesa, Queen Creek, Tempe or Scottsdale for your home. Renova coordinates the permit for the plumbing scope when required and leaves the work ready for inspection.
