Heights Plumbing, Heating & Cooling installs, services and repairs tankless water heaters for homes across North Jersey. A tankless unit heats water on demand, so you are not paying to keep 50 gallons hot all night and you are not running out mid-shower.
Tankless done right is a design job, not just a swap. Our team includes a mechanical engineer and an electrical engineer on staff, so gas sizing, venting and electrical are worked out properly rather than improvised on the day of install.
Running Out of Hot Water, or Tired of Heating an Empty Tank?
If two showers and the dishwasher drain your hot water, or the tank is crowding an already tight basement or utility closet, tankless is worth a look. It also removes the risk of 40 or 50 gallons letting go across a finished basement floor.
Tankless units have their own quirks. Hard water leaves scale on the heat exchanger, which shows up as reduced flow, fluctuating temperature or error codes. Undersized gas piping or a blocked intake or exhaust will also make a unit short-cycle or shut down. All of that is fixable.
What Our Tankless Water Heater Service Includes
For installations, we calculate your peak hot water demand in gallons per minute, account for cold incoming groundwater in winter, confirm the gas meter and piping can supply the burner, and plan a proper intake and exhaust route. We then mount and pipe the unit, install isolation valves for future flushing, handle the electrical, and commission the system.
For service, we read fault codes, test gas pressure under load, inspect venting and condensate drainage, clean the inlet filter and flame sensor, and descale the heat exchanger with a circulating flush. We finish by verifying temperature rise and flow at the fixtures, not just at the unit.
Signs Your Tankless Water Heater Needs Attention
- Hot water turns cold when a second fixture opens
- Error or fault codes on the display
- Noticeably lower hot water flow than before
- Temperature swings between hot and lukewarm
- Rumbling or scaling noise inside the unit
- Longer than usual wait for hot water
- No flush or descaling in over a year
- Exhaust or intake vent looks blocked or damaged

Our Tankless Water Heater Process
Assess the house
We count fixtures, ask how your family uses hot water, and check gas supply, venting options and electrical at the proposed location.
Size and design
We size the unit for real North Jersey winter conditions, where cold incoming water means a larger temperature rise than the rating on the box assumes.
Quote upfront
You get clear No Worries Pricing covering the unit, gas and venting work, and any piping changes before anything is ordered.
Install and commission
We mount the unit, run gas, water, venting and condensate, add isolation valves for servicing, then test flow and temperature at every fixture.
Maintain
We set up periodic descaling and inspection so the heat exchanger stays clean and the unit keeps its rated output.
Tankless Water Heater Options We Offer
Whole-home gas tankless
A single high-output unit sized to run multiple fixtures at once in a typical three or four bathroom home.
Condensing high-efficiency models
These recover extra heat from the exhaust and vent in PVC, which often simplifies venting in a basement installation.
Point-of-use tankless
A compact unit for a far-off bathroom, addition or garage where the wait for hot water is long.
Tank-to-tankless conversion
We handle the gas upsizing, new venting and piping changes needed to move from a conventional tank to tankless.
Descaling and flush service
A circulating flush that clears mineral scale from the heat exchanger and restores flow and temperature stability.
Repair and fault diagnosis
We read the codes, test under actual load, and repair igniters, sensors, valves and venting problems rather than defaulting to replacement.

Tankless Water Heaters FAQs
Does a tankless water heater really never run out of hot water?
It provides continuous hot water as long as demand stays within the unit's rated flow. Size matters. If a unit is undersized for simultaneous showers, the temperature will drop, which is why we calculate demand before quoting.
Do tankless units work well in New Jersey winters?
Yes, as long as they are sized for our cold incoming water. Winter groundwater here is much colder than the best-case numbers on the spec sheet, so we size for the winter temperature rise.
How often should a tankless unit be flushed?
Roughly once a year for most homes, and more often on harder water. Regular descaling keeps the heat exchanger efficient and helps avoid fault codes and flow problems.
Will I need gas or electrical upgrades?
Sometimes. A tankless burner demands more gas at once than a tank does, so the gas line or meter may need upsizing, and condensing units need a nearby outlet. We check all of it before we quote.
Can you service a tankless heater that another company installed?
Yes. We repair, flush and maintain existing tankless systems regardless of who installed them.
