Homes without a gas line or gas tank can likewise enjoy the benefits of on-demand hot water by setting up tankless systems powered by electrical energy. These units, which heat water with thick copper rods, are quieter and about a third smaller than gas or propane tankless heaters. And due to the fact that they do not need vents, they can be installed practically anywhere, including under sinks and in small closets.
One disadvantage to electric systems is its minimal output, which tops out at 36 kilowatts, or about 123,000 Btus. That may be enough to provide an entire home in areas with warm groundwater, however in cooler climates they’re better suited to point-of-use service, where the demand for warm water does not get too expensive. Whichever type you select, it will require sufficient amperage at the main panel and heavy-gauge wires.
Also, electric heaters last just about half as long as gas systems: Typical guarantees are 3 to five years. Once the heating elements fry, it typically costs about as much to replace the entire heater as it does to switch in brand-new aspects.
Tankless Water Heater in North Hills Setup
What you and your plumbing technician requirement to assess prior to setup day:
1. GAS LINE: For the burner in a tankless heater to carry out correctly, it needs to be attached to a gas-supply line that provides sufficient volume at sufficient pressure. In a lot of cases that indicates the diameter of the supply pipeline needs to be increased to 3⁄4 inch. And if the pressure fails, the gas company will have to change the regulator on the meter.
FYI: Some tankless systems, such as those made by Rheem, have the ability to deal with a standard 1/2- inch gas line, supplied it isn’t longer than 24 feet.
2. VENTILATION: Noncondensing tankless gas heaters utilize stainless-steel vents that can withstand high exhaust heat. Condensing systems have a cooler exhaust, and utilize cheaper PVC pipes. A concentric vent, which has an exhaust pipe inside a larger air-intake pipe, streamlines setup due to the fact that only one hole requires to be cut in the wall.
FYI: Usually, vent runs have been restricted to just 10 feet. But more powerful fans, like those in Rinnai’s Sensei series, now permit vents to run up 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 won’t 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’s worth investing in a treatment system.
FYI: A dedicated, point-of-use cartridge like the TAC-ler water conditioner (Stiebel Eltron) modifies hardness without adding salt or other chemicals.

Consider the benefits of hanging a heater outdoors, if your environment and regional codes permit.

Building policies: You might need consent from your regional building department to put it outside.
