got this water hooked up s prescribed, with a water filter on there inlet side and thus far it seems to perform as advertised. Very pleased thus far!

Kitchen faucet is 60 ft from the hot water heater, installed this inline as a booster. I needed 220v 30A dual breakers, its working fine so far. Note, this is not Westinghouse as you traditionally know it, its just the logo on a generic chinese unit.

Great purchase! Do make sure that you use 2 40amp double pole breakers with 2 runs of 8 awg wire. Just a tip, but make sure that if you are in a subpanel, that you place your ground wires into the ground bar, not the neutral bar! Flickering lights while using hot water means you have placed the ground wires in the neutral bar, so be careful! Have an expert install if you are unsure.

Too big of wattage for our house. I'm sure it's a good unit, just didn't work for us. We didn't have the right hookup for it. Sent it back.

Westinghouse 14kW 240V Tankless Water Heater Electric, Model ET014K: I got this brand over other brands because I know the name Westinghouse. UNBOXING: This water heater was heavier than expected for a tankless. The only thing else in the box besides the actual heater was when sheet instruction which also doubled as the mounting template with holes in the four corners correlating to the holes on the back of the tankless heater (pic1). I could tell that this water heater was tested before leaving the factory because the inside was still wet with water and I hadn't yet hooked it up. Installation: I had a electrician install this for me because the instructions say they have a professionally installed and it requires a direct run to the circuit box. This takes 240v and requires a 60 amp breaker. FYI most house appliances run on a 30 amp breakers. This has three wire connectors: positive, negative and ground. The instructions say that grounding is mandatory. There are two things of concern about this product: The instructions say to keep this heater away from water. It is not designed to get wet. For a product that's meant to handle water within itself, it is concerning how fragile it is to be near water. The second issue is how little water it can heat. The specs say this can only heat a MAX of 3 gallons per minute. This means it's designed to handle 1 bathroom, like 1 sink+ single shower and not multiple showers running at once. Just something to take into consideration if you're looking for hot water heater capable of handling a larger home where more than one shower might be running. I have not tested out the wireless features on this yet but as far as temperature, this heats up the water quickly and to the specified temperature. I adjust the temperature control on the graduated dial. The dial is not stepless and has little notches you can feel as you turn it which gives you a nice tactile feel. FINAL THOUGHTS: This is a well engineered piece of hardware. The output and input pipes for the water or color-coded with rubber sealed gaskets for solid connections. Everything about this heater is quality. Just be aware that You will need a professional to install this and, this draws a high current and will consume a lot of electricity during operation. Given the prices I've seen for other tankless heaters, this is a great value.
