Tankless Water Heater Installation & Service
A tankless water heater doesn't store hot water — it creates it on demand, heating water instantly as it flows through the unit. That one change delivers the benefits homeowners switch for: hot water that never runs out, energy savings of up to 34% according to the Department of Energy (you stop paying to keep 50 gallons hot around the clock), a wall-mounted footprint that frees up closet or garage space, and a lifespan of 20+ years with proper maintenance — roughly double a traditional tank.
Power Pro Plumbing installs and services tankless systems from top brands across LA and Orange County. Conversions from tank to tankless involve real work — gas line upsizing, new venting, sometimes electrical — and our estimates cover all of it upfront, so the quote you approve is the price you pay.
The rebate picture is favorable: SoCalGas offers rebates from $80 up to $1,500 on qualifying ENERGY STAR gas tankless units (scaling with efficiency tier, for installs completed by 12/31/2026 while funds last, when replacing a conventional gas tank unit in a single-family home). We'll identify which tier your unit hits and point you to the application.

Why Homeowners Go Tankless
The four advantages that drive the switch:
- Endless hot water — the unit heats on demand, so the fourth shower is as hot as the first
- Energy efficiency — no standby losses from keeping a tank hot 24/7; DOE-estimated savings up to 34%
- Space savings — wall-mounted units the size of a small suitcase replace a floor-standing tank
- Longevity — 20+ years with maintenance, versus 8–12 for typical tanks
What a Tank-to-Tankless Conversion Involves
Tankless units burn gas at a much higher rate while running than tanks do, so most conversions include upsizing the gas line to feed it. Venting is different too — tankless units use dedicated stainless or PVC venting — and a condensate drain and electrical outlet round out the typical scope. None of this is a problem; it's just real work that belongs in the estimate from day one. We size the unit by your peak flow rate (how many fixtures run simultaneously) and required temperature rise, so it performs in January, not just on paper.
Keeping It Running for 20 Years
SoCal's hard water asks one thing of tankless owners: an annual descaling flush to keep minerals from coating the heat exchanger. It's a quick service that protects efficiency and is required by most manufacturers to maintain warranty coverage. We service all major tankless brands and can put your flush on a schedule — or fold it into Power Club membership's annual water heater service.
Tankless Water Heaters FAQs
How much can I save with a tankless water heater? +
The Department of Energy estimates energy savings up to 34% versus traditional tanks, since tankless units skip standby losses entirely. Add the longer lifespan — 20+ years versus 8–12 — and lifetime economics favor tankless for many households, before counting the current SoCalGas rebates of up to $1,500 on qualifying units.
Will a tankless unit keep up with my whole house? +
Properly sized, yes. We calculate your peak simultaneous demand — showers, dishwasher, laundry — and spec the flow rate to match. Larger homes sometimes benefit from two units or a recirculation setup, which we'll flag honestly in the estimate.
What rebates are available for tankless right now? +
SoCalGas offers 2026 rebates on qualifying ENERGY STAR gas tankless water heaters, from $80 up to $1,500 depending on efficiency (UEF) tier — for SoCalGas residential customers replacing a conventional gas tank unit in a single-family home, installed by 12/31/2026, first-come while funds last. We'll confirm your unit's tier and the current program status.
Why is tankless installation more expensive than a tank swap? +
The conversion typically includes gas line upsizing, new dedicated venting, and a condensate drain — one-time infrastructure the tank never needed. Once it's in place, future tankless replacements are far simpler. Our quotes itemize all of it upfront.
