Residences without a gas line or gas tank can likewise enjoy the benefits of on-demand warm water by setting up tankless units powered by electricity. These systems, which heat water with thick copper rods, are quieter and about a third smaller than gas or gas tankless heaters. And because they don’t require vents, they can be installed almost anywhere, including under sinks and in small closets.

One disadvantage to electrical units is its minimal output, which tops out at 36 kilowatts, or about 123,000 Btus. That might suffice to supply a whole house in areas with warm groundwater, but in colder climes they’re better suited to point-of-use service, where the demand for hot water doesn’t get expensive. Whichever type you select, it will need adequate amperage at the main panel and heavy-gauge wires.
Also, electrical heaters last only about half as long as gas units: Normal guarantees are 3 to 5 years. As soon as the heating elements fry, it usually costs about as much to change the entire heater as it does to switch in new aspects.
Tankless Water Heater in Canoga Park Setup
What you and your plumber requirement to evaluate before installation day:
1. GAS LINE: For the burner in a tankless heater to carry out appropriately, it has to be linked to a gas-supply line that provides adequate volume at sufficient pressure. Oftentimes that suggests the size of the supply pipeline needs to be increased to 3⁄4 inch. And if the pressure fails, the gas business will have to change the regulator on the meter.
FYI: Some tankless systems, such as those made by Rheem, are able to work with a basic 1/2- inch gas line, provided it isn’t longer than 24 feet.
2. VENTING: Noncondensing tankless gas heaters utilize stainless-steel vents that can withstand high exhaust heat. Condensing units have a cooler exhaust, and utilize cheaper PVC pipes. A concentric vent, which has an exhaust pipe inside a larger air-intake pipeline, simplifies setup because only one hole needs to be cut in the wall.
FYI: Typically, vent runs have been restricted to simply 10 feet. But more powerful fans, like those in Rinnai’s Sensei series, now allow vents to add to 150 feet.
3. WATER HARDNESS: Scale deposits that form in a heat exchanger (or on electrical heating elements) slow down heat transfer and restrict water circulation. Scale won’t be an issue if you already have whole-house water-softening. However if your water isn’t being softened, and its firmness exceeds 120 milligrams per liter, then it’s worth investing in a treatment system.
FYI: A dedicated, point-of-use cartridge like the TAC-ler water conditioner (Stiebel Eltron) alters hardness without including salt or other chemicals.
Outside Tankless Water Heater in Canoga Park
Think about the benefits of hanging a heater outdoors, if your climate and local codes allow.
Saves space: That’s one less home appliance you need to make room for inside.
Simple to set up: The built-in exhaust vent gets rid of having to cut a big hole (or two) through the side of the house.
Easy to service: A plumbing technician can get to it at any time, whether you’re house or not. However remember …
Structure regulations: You may need consent from your local building department to put it outside.
Cold weather: Internal heaters keep components toasty down to − 22-degrees F, but exposed water pipes should be insulated and wrapped in heat tape that turns on instantly in freezing temperature levels. Frozen pipes are less of a concern south of the Mason-Dixon Line.
