Family-owned tankless installation, repair, and service since 1976. Endless hot water, lower energy bills, and a smaller footprint — sized and installed right the first time.
A tankless water heater heats water on demand — no tank standing by, no energy spent keeping forty gallons warm at 3 a.m., no cold shower at the end of the day. For the right home, the upgrade pays for itself in lower bills, longer lifespan, and the simple fact that you stop running out of hot water. Since 1976, AAA Paradise Plumbing & Rooter has been installing tankless systems across Ventura County the way they were meant to be installed: sized to the actual home, with the gas line, venting, and electrical handled properly.
We handle the whole job in-house. Gas-line sizing and upgrades, category-III stainless venting, condensate drains, electrical, mounting, descaling kits, and the warranty registration. No surprises at the end of the install.
A standard tank water heater keeps 40 to 80 gallons of water hot 24 hours a day, whether you’re using it or not. A tankless unit doesn’t store water. When you open a hot tap, cold water flows into the unit, hits a high-output heat exchanger (gas burner or electric element), and comes out hot a few seconds later. The unit only runs when you’re drawing hot water — which is why the energy savings are real.
Because the supply is continuous, you don’t run out. A long shower, a load of dishes, and the washer running at the same time will only stop if you exceed the unit’s gallons-per-minute (GPM) rating — not because something ran dry.
Both technologies work. The right choice depends on how your household uses hot water and how long you plan to be in the home.
We’ll walk through the actual numbers for your home at the quote — not a sales pitch. If a tank is the right call for your situation, we’ll say so.
A clean tankless install is more than swapping the box on the wall. Four things to evaluate first:
Most tank water heaters run on a ½-inch gas line, but most whole-home gas tankless units want ¾-inch. If your existing line is undersized, the unit will short-cycle, throw error codes, or simply not deliver rated output. We size the gas line as part of the install quote.
Tankless units don’t use the standard B-vent flue you may have with a tank. Most condensing tankless units vent through category-III stainless steel pipe, often direct-vent through an outside wall. Routing the vent properly is part of the install — not an afterthought.
Gas tankless units still need a 120V outlet near the unit for the electronic controls. Electric tankless units need a serious dedicated circuit — often 240V at 100A+ for whole-home models. Most homes’ existing panels can handle gas tankless fine, but electric tankless often requires an electrical upgrade.
Ventura County’s water carries enough mineral content to scale up the heat exchanger over time. We install a service-valve kit on every tankless so annual descaling is straightforward. Homes with hard water benefit from a softener or a scale-prevention system upstream of the tankless — we can quote that as part of the job.
We work with all major tankless brands and recommend based on your home’s requirements, not on what the truck happens to be carrying. Common installs:
For most Ventura County homes, yes — but the answer depends on how you use hot water. Tankless costs more to install (often 1.5×–2× a comparable tank), but you save on the energy bill every month (typically 25%–35%) and the unit lasts 15–20+ years versus 8–12 for a tank. Heavy-use households and remodels with limited space get the biggest payback. If your home rarely runs out of hot water with a tank, the upgrade is more about lifespan and energy efficiency than convenience.
A properly installed and maintained tankless unit typically runs 15 to 20+ years — roughly double the lifespan of a standard tank water heater. Annual descaling is the key to hitting that lifespan in Ventura County’s hard water. Skip the maintenance and you can cut effective life in half.
Sometimes yes, sometimes no — three things matter. (1) Gas line size: most tank water heaters run on a ½-inch gas line, but most whole-home gas tankless units want ¾-inch. (2) Venting: tankless units use category III stainless venting or direct-vent through an outside wall — different from a typical tank’s B-vent. (3) Electrical: gas tankless still needs a 120V outlet, electric tankless needs a substantial dedicated circuit (often 240V at 100A+). We’ll evaluate all three at the quote stage and tell you exactly what your install requires.
Yes, but unit sizing matters more than it does for tanks. A tankless heats water as you use it, so it’s rated by gallons per minute (GPM) at a given temperature rise, not by tank size. For a 4–5 person home running two showers and a dishwasher at once, you want a unit in the 8–11 GPM range. We size based on your peak simultaneous demand, not a generic recommendation.
Yes, and it matters more here than in soft-water markets. Ventura County water carries enough minerals that scale will build up inside the heat exchanger. An annual descaling (flush) keeps the exchanger clean, preserves efficiency, and protects the manufacturer warranty. Skip it and the unit can lose efficiency, throw error codes, or fail early.
Both. We install and service gas tankless (most common for whole-home use) and electric tankless (often used for point-of-use applications or all-electric homes). We work with all major brands — Rinnai, Navien, Bosch, Rheem, Noritz, A.O. Smith — and can usually recommend the right brand and model for your home, not just whatever the truck is carrying.

I have tried five different plumbing companies before I found Paradise Plumbing 5/5 .. Henry Zamecki! Worked on Xmas eve in the rain! I have hot water!!! Fair pricing, excellent work!! Highly recommend.
I had an excellent experience with Henry and Paul when they installed my new water heater. From start to finish, they were professional, and friendly. They arrived on time, explained everything clearly, and made sure I understood how the system worked before they left. The installation was done quickly and neatly, and they left the space cleaner than they found it. Will call back for all future plumbing needs!
Freddy did a fantastic job installing my water heater this past weekend. He was very professional and neat. He cleaned up his workspace and showed me before/after photos of the installation. Will be calling back Paradise for all future plumbing needs!
I highly recommend this company, along with the two employees we met: Ruben and Jeremy. Ruben assessed the situation initially, Jeremy dropped by shortly thereafter for a look see, then both performed the removal and install of a new water heater, along with necessary venting work. They did not leave the job until they were satisfied that everything was completed correctly and in one visit! Again, thanks to these very conscientious, dependable and personable workmen! Because of our experience and their workmanship, this company is on the top of my list for any future plumbing needs!
Our water heater went out on a Sunday. AAA Paradise was the only company who had someone available to respond. A young man named Fred came out. He was the most courteous person we have met in a very long time. Fred worked Sunday afternoon to drain and remove the leaking water heater but did not have a new one available until Monday morning. He capped off the gas line so that we could still use the stove and heater. Fred came back and worked until 6:30 pm restructuring the closet and replumbing the new water heater. He had to crawl under the house several times without complaining. We are very impressed with Fred and his hard work to address all of our concerns. We will definitely call AAA Paradise Plumbing for all future plumbing needs. We are very satisfied. And again, Fred was a great ambassador for this company.
