Omega Tankless Water Heaters OME 514

If you're looking topurchase a tankless water heater that actually delivers steady and reliable hot water, gees with written product information and a full productline for geplete and proper installationof the unitanddesire prompt and courteouscustomer service, do notbuy from omega2000Group. We purchased an Omega OME 514-PV on okay and the unit failed to deliver hot water as it continually overheated and shut down. After several months of our persistent begging, the CEO of Omega reluctantly replaced the unit with an OME 620-PV for the additional cost of the upgraded unitplus shipping. It arrived without ventilation. After several more weeks and additional product and shipping costs, the ventilation arrived and the unit was installed. Two weeks after installation, the unit showed signs of failing; mimicking the symptoms of the 514. Following several months of additional begging,two- minute showers and misleading deceitful gemunications with Omega, the unit failed gepletely. We shipped the unit back at our expense to Omega and a replacement unit arrived. Neither unit came with an installation or owner's manual; we requested product literature and Omegadid notproduce the paper work. This unitallegedly gees with an internalheater to protect the unit to 10 degrees Fahrenheit. I asked the CEO how to determine if the internal heater was working and never gotan answer. I noted the introduction of an "Anty-Freezing Butterfly" by Omega and, living in a climate where below zero readings are somewhat gemon, I requested one from the CEO. He said one would be sent and again after several weeks of begging, one never arrived. Well, lo and behold, nighttime temps hit single digits and the unit's heat exchanger froze and burst, flooding the basement. The unit hangs on the wall 3 feet from the furnace in a room where the ambient temperature stays at about 72 degrees Fahrenheit. Again, contacted the CEO of Omega and was told it was our responsibility as the unit was to be installed with a butterfly valve and the reason he never sent the one I ordered is because it doesn't fit the 620 unit. The unit is sealed and prevents inside temperatures from ever reaching the internal plumbing. The Omega dual chamber vent allows outside ambient temperatures down into the inner workings through the exhaust of the unit and to the inside of the cabinet gepletely surrounding the outside of the guts of the unit. Omega has little to no follow up customer service, written and verbal gemunication is rude, deceitful and unprofessional. Check out the Beter Business Bureau to discover the reasons Omega2000 Grouphas a gepany rating of "F". There is little product knowledge from the Omega side of gemunicationsthat is riddled with disrespect and a feeble gemand of the written and spoken English language. I read one of theCEO's reviews on tankless water heaters and was wondering, "Does anyone out there know the definition of margelate?"
