Homes without a gas line or lp tank can also enjoy the advantages of on-demand warm water by installing tankless systems powered by electricity. These systems, which heat water with thick copper rods, are quieter and about a third smaller than gas or lp tankless heaters. And since they don’t require vents, they can be set up almost anywhere, including under sinks and in small closets.

One disadvantage to electrical systems is its limited output, which peaks at 36 kilowatts, or about 123,000 Btus. That may suffice to provide a whole home in areas with warm groundwater, however in cooler climes they’re much better suited to point-of-use service, where the need for warm water doesn’t get too expensive. Whichever type you pick, it will require sufficient amperage at the main panel and heavy-gauge wires.
Also, electric heaters last only about half as long as gas systems: Typical service warranties are 3 to five years. When the heating elements fry, it normally costs about as much to replace the entire heater as it does to switch in new components.

What you and your plumbing technician need to examine before setup day:
1. GAS LINE: For the burner in a tankless heater to carry out correctly, it needs to be hooked up to a gas-supply line that provides enough volume at enough pressure. In most cases that suggests the size of the supply pipe has to be increased to 3⁄4 inch. And if the pressure fails, the gas company will need to change the regulator on the meter.
FYI: Some tankless units, such as those made by Rheem, have the ability to deal with a standard 1/2- inch gas line, provided it isn’t longer than 24 feet.
2. VENTING: Noncondensing tankless gas heaters use stainless-steel vents that can endure high exhaust heat. Condensing units have a cooler exhaust, and utilize more economical PVC pipes. A concentric vent, which has an exhaust pipe inside a bigger air-intake pipeline, streamlines setup since only one hole needs to be cut in the wall.
FYI: Normally, vent runs have been limited to simply 10 feet. However more powerful fans, like those in Rinnai’s Sensei series, now enable vents to run up to 150 feet.
3. WATER HARDNESS: Scale deposits that form in a heat exchanger (or on electrical heating elements) slow down heat transfer and constrict water circulation. Scale will not be an issue if you already have whole-house water-softening. But if your water isn’t being softened, and its firmness goes beyond 120 milligrams per liter, then it’s worth purchasing a treatment system.
FYI: A dedicated, point-of-use cartridge like the TAC-ler water conditioner (Stiebel Eltron) alters firmness without adding salt or other chemicals.
Outside Tankless Water Heater in Studio City
Consider the benefits of hanging a heater outdoors, if your environment and regional codes allow.
Saves space: That’s one less home appliance you have to make room for inside.
Simple to install: The built-in exhaust vent gets rid of needing to cut a big hole (or two) through the side of your home.
Easy to service: A plumbing technician can get to it at any time, whether you’re home or not. However keep in mind …
Structure guidelines: You may need permission from your regional building department to put it outside.
Winter: Internal heaters keep parts toasty to − 22-degrees F, but exposed pipes must be insulated and wrapped in heat tape that switches on instantly in freezing temperature levels. Frozen pipes are less of a concern south of the Mason-Dixon Line.
