Tankless Water Heater Installation for Tempe Homes
We have installed tankless water heaters in Tempe laundry rooms, with new copper water lines, gas connections and venting. In Tempe's older homes, the gas line and venting usually need updating for tankless. South Tempe's 1970s and 1980s homes often have more room to work. Every install includes service valves for flushing.

How the Job Works
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.

Tankless Water Heater Installation in Tempe: Questions
Often, yes. A laundry room can be a good spot if the gas line can be sized for the heater and the unit can vent to the outside properly. We have done this in Tempe homes. We check the wall, the gas supply and the vent route before recommending it.
Timing depends on the job, not the city. As a guide, site check takes under an hour, and tankless replacing tankless takes several hours. Every job is scoped upfront, so you know the timeline before work starts, and we set a visit time that works for you in Tempe.
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.
