The End of the "Cold Shower" Race

You know the routine. You have to wake up early to get a hot shower before the kids use it all. Or you have to wait an hour after running the dishwasher before you can take a bath.

Living with a traditional tank means you are limited by how many gallons it holds. Once it’s gone, it’s gone.

At On Tap Plumbing, we believe you shouldn’t have to schedule your life around your water heater. A tankless hot water heater installation solves this problem instantly. It heats water as it flows through the unit. It never runs out.

But installing these systems is not a DIY job. They require precise gas line sizing and specialized venting. We are Level 3 Navien Certified experts. We don’t just hang the box on the wall; we calculate the load to make sure your system performs perfectly for years.

Our Tankless Services

We handle everything from converting old tanks to maintaining high-tech units.

We remove the old unit, upgrade the gas lines if needed, and install tankless water heater units that mount neatly on your wall. You gain back valuable closet or garage space.

We give you an honest comparison. While a tankless water heater cost to install is higher upfront, the energy savings and longevity (20+ years) often make it the smarter financial choice in the long run.

Tankless units have one enemy: hard water. Scale buildup can destroy the heat exchanger. We perform annual descaling flushes to keep your warranty valid and your water flowing freely.

Restaurants and salons use massive amounts of hot water. We install cascaded tankless systems that link multiple units together. If one unit needs service, the others keep running, so your business never stops.

Why Choose On Tap for Your Tankless Water Heater Install?

Tankless technology is advanced. You need a technician who understands the computer boards, sensors, and flow valves inside these machines.

Frequently Asked Questions (FAQ)

Does a tankless heater really provide instant hot water?
It provides endless hot water. It still takes a moment for the water to travel from the unit to your faucet, just like a tank. But once it arrives, it will stay hot forever.
Sometimes, but often we need to upgrade the gas line size. Tankless units need a sudden burst of high BTUs to heat water instantly. We calculate this during our estimate.
Typically one day. We remove the old tank, handle the new venting and piping, and have you running on the new system by dinner time
If you plan to stay in your home for more than a few years, yes. The energy savings and the extended lifespan (20 years vs 10 years for a tank) pay off.
Yes. While we specialize in Navien, we are trained to repair and maintain most major tankless brands.
