Tankless Water Heater Installation in Gretna, NE
A tankless (on-demand) water heater heats water only as you use it, so you get endless hot water, lower standby energy costs, and a wall-mounted unit that frees up floor space and can last 20+ years. JTM Plumbing & Drain installs, converts, and services tankless water heaters across Gretna and Omaha, sized to your home's flow and installed with the correct gas line and venting.
Serving the metro since 2004, we'll tell you honestly whether tankless pays off for your household before you spend a dime. Call Gretna (402) 203-6193 or Omaha (402) 933-3690.
Tankless services we provide
- Tankless installation: gas and electric, sized to your flow rate
- Rheem tankless units: professional-grade gas and electric models we install and service
- Tank-to-tankless conversion: including gas line and venting upgrades
- Tankless repair: ignition, flow sensor, error codes, no-hot-water
- Descaling & maintenance: essential in Omaha's hard water
- Whole-home vs. point-of-use sizing guidance
- Code-compliant venting & condensate handling
Tankless units are fantastic, but Omaha's hard water scales up the heat exchanger faster than in soft-water markets. The fix is simple: an annual descaling (and ideally a softener) keeps a tankless running at full efficiency for its full 20+ year life. We build maintenance into the plan so your investment lasts. Call the Omaha line at (402) 933-3690.

What our customers say
Tankless vs. tank: which is right for you?
