Most people only think about the water heater the morning it stops working. A tankless unit heats water as you use it, so it does not run out.
A tank heater keeps a set amount hot and runs cold once that is gone, while a tankless unit fires when a tap opens and shuts off when it closes, so the supply keeps coming at its rated flow. The catch is that flow, because a house running several fixtures at once needs a unit sized for it, and that sizing is the part of the job worth getting right.

Frank works out of Waretown and covers 15 Ocean County towns, among them Barnegat, Long Beach Township and Waretown. See all the towns he covers.
Call, give the township notice, then put the new heater in.
You call and describe it
Call (732) 269-7978 and say what the heater is doing, roughly how old it is and whether it runs on gas or electric. A photo of the label on the unit helps.
The township gets notice
Under the state construction code, replacing a water heater with one of like capacity is minor work, so notice goes to your township's construction office before the old unit comes out, and the permit follows.
The new heater goes in
The new unit is piped in, vented and started up, and a switch to tankless is planned around how much hot water the house actually uses at once.
If you want Frank to look at yours, call him at (732) 269-7978 or send the job over.

Water heater questions
Each answer links to the source it was read from: the state code, a federal energy page, a township page or his own site.
Do I need a permit to replace a water heater in New Jersey?
Yes, but it is the lighter kind. The state construction code treats the replacement of an existing water heater with a new one of like capacity as minor work, which means notice goes to the township's construction office before the work begins and the permit can follow. A bigger change, like a different kind of unit, is worth asking the office about first.
The state code (PDF)How much hot water can a tankless water heater make?
The U.S. Department of Energy puts high-efficiency tankless heaters at roughly 2 to 5 gallons per minute. That is plenty for one shower, but a house running two showers and the washer at the same moment needs a unit sized for it, or two units, which is why the sizing gets worked out before anything is ordered.
U.S. Department of EnergyWhich tankless brands does Haskell install?
His own site named Buderus, Rinnai, A.O. Smith and Navien, and it noted that a tankless unit can also work as a combination hot water and boiler unit with a hydronic heating system. Call and say what you have now, and the right unit follows from the house.
