A planned water heater installation gives you time to choose well, and the choice matters for the next ten to fifteen years. Lodi Pro Plumbing installs standard tank, heat pump hybrid and gas and electric units in Lodi, NJ, and the plumber explains the options in plain terms before anything is ordered. If your current heater has already failed, the replacement page covers the emergency version of this job.
Installation covers the whole system around the heater: supply lines, shutoff valves, a relief valve and discharge pipe, an expansion tank where needed, venting for gas units and the electrical circuit for electric ones. A heater is only as good as the plumbing around it.
When you need an installation and not a swap
Installation is the right word when the job goes beyond trading one tank for another:
- You are moving the heater during a basement or kitchen remodel.
- You are switching fuel, for example from gas to a heat pump unit.
- You are adding a second heater for a large household or a finished basement bath.
- A new bathroom or apartment unit needs its own hot water supply.
- You want to move a heater out of a flood-prone corner of the basement.
Each of these changes something beyond the tank, such as a gas line, a vent route or a circuit, so the plumber surveys the space first.
Which type fits your home
| Type | Best for | Watch for |
|---|---|---|
| Gas tank | Homes with a gas line and a working flue | Venting and combustion air |
| Electric tank | Homes without gas, small spaces | Higher running cost, circuit size |
| Heat pump hybrid | Larger households that want lower electric bills | Needs space and air around it, makes cool air and noise |
| Tankless | Small households or limited floor space | Gas line and vent upgrades, see the tankless page |
A heat pump unit needs a room with enough air volume and some clearance, and it pulls heat from the room, so a cold corner of the basement can lower its output. A gas heater needs a flue that vents properly. The plumber checks both before recommending anything.

Call (973) 488-5410What the installation includes
A complete install covers these steps:
- Survey the location, the fuel, the venting and the pipe routing.
- Shut off and drain the old unit if there is one, and set the new heater on a stable base or pan.
- Run new water connections with shutoff valves and unions so the heater can be flushed and serviced.
- Install the relief valve, its discharge pipe and an expansion tank if the system calls for one.
- Connect gas and vent or the electric circuit, test for leaks and start the heater.
- Set the temperature, explain the controls and show where the shutoffs are.
Unions and shutoff valves look like small extras, but they are what make a yearly flush a ten-minute job instead of a plumbing repair.
Planning around Lodi water
Lodi's water comes from the Passaic Valley Water Commission, whose 2026 report shows the Little Falls plant's water ranging from 106 to 242 ppm hardness and the blended Wanaque water at 42 ppm. Your tap may fall anywhere in that range depending on the blend. A heater installed with flush access and a plan to descale it will last longer than one buried behind unions that cannot be reached.
If you are in Hackensack, Hasbrouck Heights, Maywood or Wood-Ridge, the water is Veolia's Hackensack system, where the highest hardness reported is 210 ppm. Either way, ask about a flush schedule when the heater goes in.
What decides the cost of a new installation
- Heater type
- A heat pump unit costs more up front than a standard electric or gas tank.
- New work
- Running a new gas line, a vent or an electric circuit adds materials and time.
- Location
- A heater moved to a new spot needs new supply and drain lines.
- Extras
- Expansion tanks, drain pans and shutoff upgrades are listed in the quote.

Water heater installation questions
How long does a new installation take?
A straightforward replacement in the same spot takes a few hours. A relocation, a fuel switch or a new gas line takes longer, and the plumber gives you the schedule when quoting.
Do you install heat pump water heaters?
Yes. We will check the room, the air volume and the electrical supply before recommending one.
Do I need an expansion tank?
Some systems need one, especially where a check valve or pressure regulator keeps the water from expanding back into the street. The plumber tests your system pressure and tells you.
Can I install it myself?
Plumbing and gas work on a water heater has real safety and code consequences. We recommend hiring a licensed plumber and checking local permit rules first.
What if the new heater should go upstairs?
That is possible when there is a place for the drain pan and the discharge pipe. It is a good option for flood-prone basements.
