Homes without a gas line or lp tank can likewise enjoy the benefits of on-demand hot water by setting up tankless systems powered by electrical energy. These systems, which heat water with thick copper rods, are quieter and about a 3rd smaller than gas or propane tankless heaters. And since they don’t require vents, they can be set up almost anywhere, including under sinks and in little closets.

One disadvantage to electrical units is its minimal output, which tops out at 36 kilowatts, or about 123,000 Btus. That may be enough to provide a whole home in areas with warm groundwater, but in cooler climes they’re better suited to point-of-use service, where the demand for hot water does not get expensive. Whichever type you select, it will need enough amperage at the primary panel and heavy-gauge wires.
Also, electric heaters last only about half as long as gas units: Normal guarantees are three to five years. As soon as the heating elements fry, it typically costs about as much to change the entire heater as it does to switch in new aspects.
Tankless Water Heater in Chatsworth Installation
What you and your plumber need to assess before installation day:
1. GAS LINE: For the burner in a tankless heater to carry out correctly, it has to be attached to a gas-supply line that provides adequate volume at adequate pressure. Oftentimes that implies the size of the supply pipe needs 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 basic 1/2- inch gas line, supplied it isn’t longer than 24 feet.
2. VENTING: Noncondensing tankless gas heaters use stainless-steel vents that can withstand high exhaust heat. Condensing units have a cooler exhaust, and utilize less costly PVC pipes. A concentric vent, which has an exhaust pipe inside a larger air-intake pipe, simplifies installation because only one hole needs to be cut in the wall.
FYI: Typically, vent runs have been limited to just 10 feet. But more powerful fans, like those in Rinnai’s Sensei series, now enable vents to add to 150 feet.
3. WATER HARDNESS: Scale deposits that form in a heat exchanger (or on electric heating elements) decrease heat transfer and constrict water flow. Scale won’t be an issue if you currently have whole-house water-softening. However if your water isn’t being softened, and its solidity exceeds 120 milligrams per liter, then it deserves purchasing a treatment system.
FYI: A dedicated, point-of-use cartridge like the TAC-ler water conditioner (Stiebel Eltron) changes hardness without adding salt or other chemicals.
Outdoor Tankless Water Heater in Chatsworth
Think about the advantages of hanging a heater outdoors, if your climate and local codes permit.
Saves space: That’s one less appliance you have to make room for inside.
Easy to install: The built-in exhaust vent eliminates needing to cut a huge hole (or more) 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 keep in mind …
Building regulations: You may require permission from your local structure department to put it outside.
Winter: Internal heaters keep components toasty to − 22-degrees F, however exposed water pipes must be insulated and wrapped in heat tape that turns on instantly in freezing temperatures. Frozen pipes are less of an issue south of the Mason-Dixon Line.
