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

One drawback to electrical systems is its minimal output, which peaks at 36 kilowatts, or about 123,000 Btus. That might suffice to provide an entire home in areas with warm groundwater, but in cooler climes they’re much better suited to point-of-use service, where the need for warm water does not 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: Common warranties are 3 to five years. When the heating elements fry, it generally costs about as much to replace the entire heater as it does to switch in brand-new aspects.
Tankless Water Heater in Mission Hills Setup
What you and your plumber requirement to assess prior to setup day:
1. GAS LINE: For the burner in a tankless heater to perform properly, it needs to be hooked up to a gas-supply line that provides sufficient volume at sufficient pressure. Oftentimes that implies the diameter of the supply pipe has 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 units, such as those made by Rheem, have the ability to work with a standard 1/2- inch gas line, supplied it isn’t longer than 24 feet.
2. VENTILATION: Noncondensing tankless gas heaters use stainless-steel vents that can withstand high exhaust heat. Condensing systems have a cooler exhaust, and use less costly PVC pipes. A concentric vent, which has an exhaust pipe inside a bigger air-intake pipe, simplifies installation due to the fact that only one hole requires to be cut in the wall.
FYI: Normally, vent runs have been restricted to simply 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) slow down heat transfer and restrict 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 solidity goes beyond 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) alters hardness without adding salt or other chemicals.
Outdoor Tankless Water Heater in Mission Hills
Consider the advantages of hanging a heater outdoors, if your environment and local codes permit.
Saves space: That’s one less device you have to make room for inside.
Easy to install: The built-in exhaust vent gets rid of needing to cut a huge hole (or more) through the side of your home.
Easy to service: A plumbing professional can get to it at any time, whether you’re home or not. However remember …
Building regulations: You might need authorization from your regional building department to put it outside.
Cold weather: Internal heaters keep components toasty to − 22-degrees F, but exposed pipes must be insulated and wrapped in heat tape that switches on immediately in freezing temperatures. Frozen pipes are less of a concern south of the Mason-Dixon Line.
