Electric Tankless Water Heater in Van Nuys
Houses without a gas line or propane tank can likewise enjoy the advantages of on-demand hot water by installing tankless systems powered by electricity. These units, which heat water with thick copper rods, are quieter and about a third smaller than gas or gas tankless heaters. And because they do not require vents, they can be set up almost anywhere, including under sinks and in small closets.
One disadvantage to electric systems is its limited output, which peaks at 36 kilowatts, or about 123,000 Btus. That may suffice to provide a whole home in locations with warm groundwater, but in colder climates they’re much better suited to point-of-use service, where the demand for hot water doesn’t get too expensive. Whichever type you choose, it will need sufficient amperage at the main panel and heavy-gauge wires.
Also, electric heaters last just about half as long as gas systems: Common warranties are 3 to 5 years. As soon as the heating elements fry, it normally costs about as much to replace the whole heater as it does to swap in brand-new elements.
Tankless Water Heater in Van Nuys Setup
What you and your plumbing professional requirement to evaluate before setup day:
1. GAS LINE: For the burner in a tankless heater to carry out effectively, it has to be attached to a gas-supply line that delivers sufficient volume at enough pressure. In a lot of cases that means the size of the supply pipe needs to be increased to 3⁄4 inch. And if the pressure fails, the gas business will need 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, offered 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 cheaper PVC pipes. A concentric vent, which has an exhaust pipe inside a larger air-intake pipe, simplifies installation due to the fact that only one hole requires to be cut in the wall.
FYI: Generally, vent runs have been restricted to just 10 feet. However 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 electric heating elements) decrease heat transfer and restrict water circulation. 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 surpasses 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 solidity without adding salt or other chemicals.
