Complicated Retrofit - Great Product

I converted two 40 gallon traditional water heaters into one 50 gallon Vertex for my home. I personally had a complicated installation because i had to reroute copper cold supply and hot return lines in the wall, reroute existing AC condensation line, add an electrical outlet, new drywall, new copper outside the wall for connection, reroute home electrical ground to cold pipe, reroute new exhaust into existing roof vent, and add overflow drain to garage floor. My installation was not DIY friendly but my existing situation was not desirable either. Once complete it seems to work very well and I haven't ran out of hot water yet. One bonus was this unit came with the exhaust Vent Attenuation Assembly Kit (vent muffler basically). I didn't see this item mentioned anywhere on the website but i'm glad it came with one. The unit is behind our living room wall and I can hear when the blower turns on. The noise is a small hum but nothing i have to turn up TV over. Time will tell if this unit lasts but so far so good. Quick note for connection sizes/types not listed: 1) Cold Supply Inlet: 3/4" Male NPT, comes with nipple installed 2) Hot Return Outlet: 3/4" Male NPT, comes with nipple installed 3) TPR Valve: 3/4" Female NPT 4) Condensate Drain: 1/2" Female PVC Slip 5) Gas Supply Inlet: 1/2" NPT 6) Vent and Muffler: 2" PVC Connection

Unit making popping noises

We are a large family of 7 and purchased this unit because of it's efficiency and rapid heating ability. We have been extremely happy with it's heating performance and have not run out of hot water yet. There is one issue though that causes me to downgrade the product. Around 13 months after installation, the unit started making loud popping noises. Our plumber said that it was due to sediment and to drain the tank. We followed the instruction manual and drained the tank, which took care of the problem for about 5 months. The popping sound has returned, but draining the tank does not correct the problem. When we called AO Smith, they sent us a new blower, but that did not correct the problem. AO Smith then scheduled a service call (which was supposed to be $60 and ended up costing us $147). The technician said the same thing, "you have sediment in the tank and it needs to be drained." We had just drained the tank twice and it did not correct the problem. So he drained it again, and it did not correct the problem. The technician also tested the water and the hardness was "normal" (so no extra-ordinary sediment should be in the tank). At this point, we are filing a claim with the warrantly department to get a new tank. This tank is only 20 months old. The verdict is still out on whether or not I would recommend this product. At this point, it depends on how well their warranty dept. fixes this problem.

Water Heater shipment

Yes. I was surprised that the shipping company brought a damaged unit to my home. I had to send it back and supplyhouse sent another unit in a reasonable amount of time all worked out fine in the end. The unit was clearly damaged by a forklift, not subtle.

AO Smith Vertex

I purchased the AO Smith Vertex water heater to heat my garage floor. This unit replaces an old water heater that was not very efficient. So far, this unit stays on approximately half as long as the old unit. It is very quiet and is rated at 90%efficient. I'm looking forward to substantially lower gas bills this winter. I highly recommend the Vertex heater and Supply House was excellent to work with.

Best residential water heater on the market of any type IMO

This water heater is simply amazing. We never run out of hot water regardless of what we're doing. It's efficient and it has great insulation to avoid standby loss. We had it installed in a metal drip tray and below the tray a half inch closed cell foam board to stop heat transfer into the cement slab. We have our water treated with a water softener which is important for the life of a water heater and we have the electrical plug of this water heater plugged into a battery backup/surge suppressor to avoid damage to the electrical components of this water heater if the electricity has issues. It's quiet while it's heating up water with just a little sound from the forced exhaust fan. The first time we turned it on it only took about 15 minutes to fully heat up from being completely cold.

I would buy this item again

I bought this water heater and love it, I would've gave 5 stars, but shipping destroyed one of my heaters and had to wait again for new shipping. However, Supply House got right on it and had a new item sent right away to minimize the wait!

Not impressed

Unit was shipped promptly and arrived in perfect condition. It died 5 days after instillation. AO Smiths technical support was helpful in figuring out that the blower had gone bad, and said they'ed send me a replacement blower, but I had to pay the shipping. I'm not happy having to pay to get replacement parts for a brand new defective water heater. I'll be buying another brand from now on.

Extremely Efficient

Used for residential hot-water only. Easy to install. Very Efficient and fast recharge time. Condensate return line is a must, taking a shower will cause a good amount of water to drain from system. Is quieter than previous power vent model.

Popping and Clanking

I installed an AO Smith GPHE 50 100 Vertex unit in our home 3 years ago. Over the past year it has become a real noise maker----clanking and popping every time it fires-up. I regularly flush the system with no resultant reduction in the popping and clanking. We get our water from Lake Michigan via our village--nothing unusual about our water. It really sounds as if some of the internals are loose. The sound just rattles through the house and is very annoying. It is one thing to get used to the jet engine blower sound, but the rattle and popping is unacceptable.

Q: For power vent models, is it possible to vent into a chimney stack without running a new vent pipe all the way to the end of the chimney? Our current water heater just connects directly into the chimney stack and has a dedicated run for exhaust (no internal piping).

I think there is too much water in the exhaust gases from the power vent to put in a regular chimney.

It would seem logical to follow the same path. You will have additional moisture in the chimney. The Vertex has a cutout switch that compares the atmospheric pressure at the unit to the back pressure in the stack. Since the chimney is much larger than the 2" pipe off the unit, there should be no cumulative back pressure to speek of. If anything else shares the same flu, then all bets are off. If you are at high altitude, then you may still need the high altitude switch in the Vertex. Sent from my Verizon Wireless Phone

I suspect you COUlD vent it to a chimney, but you should check with your local county office for regulations. This particular heater has a LOT of moisture in the exhaust also, so there will likely be some condensation. Will water dripping down your chimney be a problem? If so, you may want to exhaust outside. Sent via BlackBerry by AT&T

You may want to note any error codes displayed on the unit and refer to them on pages 35 and 36 of the manual linked below. Problems with the pressure switch can cause the blower to run continuously. http://s3.pexsupply.com/manuals/1329168611501/71279_PROD_FILE.pdf

Q: Hi Does this unit qualify for the NJ clean energy program rebate? It states..."Gas Water Heater with 90% or greater thermal efficiency with sealed combustion" I know it's 90% efficient but is it also a sealed combustion system?

Asked by John 14 years ago

"Sealed combustion" generally refers to direct vent units. The GDHE-50 is the direct vent version of the Vertex. You may want to check with the state or utility company, however, regarding their specific definition.

We would recommend that you use a condensate pump.

No, without a drain, you cannot use this heater. Your other option is to build a sump pit and pump the water to a drain line.

Q: I have a 75 gal heater now and is 24 years old,and I was thinking it`s time for an upgrade. I also have my basement base board heating on the same water heater off a pump. My plumber said the GPHE-50 can handel both because there is a hook up at the bottom. Is he correct? Also I an on a well system, do I need to concider any additional add-on with the GPHE-50

The hook up for this unit is on the side. We would recommend installing strainers in the system.
