A tankless water heater gives you hot water on demand — no tank to run out, no tank taking up space, and a longer service life. We’ve installed them across Lancaster County, and because we’re licensed plumbers, the gas, water, and venting side is all handled by the same team.

Sized to your household

Tankless is about matching the unit to how much hot water your home actually uses at once. We size it to your household so you get steady hot water where you need it, not a unit that can’t keep up or one you overpaid for.

The honest read

Tankless isn’t automatically right for every home, and we’ll tell you straight whether it fits yours or whether a good tank makes more sense.

Questions we hear a lot

Is a tankless water heater worth it?

For a lot of households, yes — endless hot water, a smaller footprint, and a longer service life than a tank. Whether it's the right call depends on your hot-water demand and your home's setup, and we'll give you the honest math before you decide.

Can you replace my old tank with a tankless unit?

Usually, yes. There's sometimes gas or venting work involved, which is exactly the kind of thing that's easier when your plumber and your installer are the same shop — us.

“Fantastic company! They have done plumbing repairs and have installed a new HVAC system in my house. They listened attentively to my concerns and answered with feedback and suggestions in a way that I understood the whole process.”

“Tom Falk plumbing has helped us for over 20 years. Their response to calls is very prompt, and needed work is explained and then done efficiently. Recently Jeff proactively replaced our very old main water shut off valves. A few years ago they solved a complicated problem with a century-old bathroom drain pipe. Work areas are carefully cleaned when they're finished. Highly recommended.”

Scheduling was easy, they arrived when they said they would, and they were friendly, respectful, and thorough. I would recommend them for any AC, plumbing or heating issue you may have, they’ve earned my trust.”
