User questions & answers

Question: Will this work in High altitude
Answer: Just opened mine and the "cautions" and "general instructions" are rather adamant about saying: DO NOT INSTALL ABOVE 5,200 feet. Our EX22CP also said it was good at high altitude, but that manual under Specifications says it is for installation at altitudes up to 10,200 feet. Here in Western Colorado, folks in our valley's wouldn't be able to use this. We're at 8'000 feet, so I guess it is going back. REALLY disappointing.
Question: can this heater be accessed via the internet
Answer: You would need a wifi thermostat.
Question: Is it metal construction
Answer: No its plastic
Question: how many btus
Answer: Unless I am having trouble reading, THERE IS NO BTU RATING... This is a very poor ad. Will it run on battery alone?

User questions & answers

Question: can you use 5/8 propane pipe or do you have to use 1/2 inch? I have a bunch of 5/8 inch and wanted to use it
Answer: I used 1/2" soft copper tubing from the propane tank to where it entered the building. From that point we used standard steel black pipe-probably 1/2"pipe. I don't know what 5/8 propane pipe is. Do you mean 5/8" dia. copper tubing? As far as I know pipe sizes come in these designations:1/8",1/4", 1/2" 3/4",1', etc. The numbers refer to the inside dimension of the pipe-(the opening,) not the outside dia.I do not know of a 5/8" pipe. It's best if you don't try and improvise. Follow the mfrs. instructions. Your home is worth more than something you have a "bunch of" already. If you are talking 5/8"dia. copper tubing I don't think that would be a problem but like a previous responder said: 1/2" dia.copper tubing is pretty much a standard
Question: Is the hook up kit (hose) shown in frequently bought together necessary
Answer: The unit came with the required shutoff valve and I just had to go to Home Depot and pick up the gas line with the length I needed for my hook up. It was pretty inexpensive getting the hose there.
Question: What is the btu rating of the fc824p heater
Answer: output on low 6000 btu high 16000 btu
Question: We have been researching the rinnai fc824p are there sea level specifications we need to be concerned about we are at 4000 ft
Answer: I use two of these units, one in my pump house and one in a portion of my barn that has water. I'm at 7,000 feet and they work great. The one thing I had to do is to add a UPS to give the units constant power for when the power goes out.

User questions & answers

Question: Can the temperature output be adjusted to 105F
Answer: Most rinnai tankless weather it is out door or indoor, have a control board to adjust temp and either on or off
Question: Can I use the Rinnai V65EP in Denver, Co? Temperatures during the winter can get below zero
Answer: It can definately be out doors in freezing temps, tho power failure arent good for it while in a freeze, tho keep in mind it will use alot more energy for frost protection, indoor units are safer amd more efficient in this case
Question: Does this unit come with controller? rinnai tech said i needed a mc-91-2us controller? do i need to buy separate
Answer: I bought model V65EN. It came with a wired digital controller. The installer did not run the wire into the house and mount the controller indoors. He simply set the controller at 120 degrees and left the controller inside the unit. If I want to change the temp, I have to take the cover of the unit.
Question: What does the "Low NOx Mean
Answer: Good place to check for info like this is Wikipedia. Here is what they say: Energy efficiencieseditMore tangible cost savings are defined when comparing the energy efficiencies of gas heaters with low NOx emissions with conventional flued types. Gas heaters with emission problems are flued and inherently lose substantial energies in the form of hot flue gases to the atmosphere. In addition, the choice of placement of flued heaters is greatly impaired due to flue installation restrictions.In contrast, dedicated low emission gas heaters do not require a flue system. Furthermore, with the introduction of oxygen depletion sensors and thermostatic controls, they do not place critical reliance on ventilation as previously was the case. These heaters can be positioned more conveniently and centralised to affect optimum warm air distribution. By definition unflued low NOx gas heaters are 100% efficient as all heat energy released from the flame is converted to useful heat.Hope this helps. June

User questions & answers

Question: which models are "condensing" units, please
Answer: I don’t know. But I suggest u look for a different brand. It already failed twice in less than a year and their warranty is a scam. They provide the parts which are pennies and leave out labor.
Question: How does it effect the water pressure, will it change
Answer: It does not effect my water pressure at all. I’ve had it for over a year now
Question: My existing water heater is located next to and shares a flue with the furnace. Can I hook the same way on this
Answer: Hold up there, previous answer, not so fast. It is true that you should not have both the hot water heater and furnace venting directly into the flue, combining the exhaust. However, some people see their vent pipes entering the flue (or chimney wall) and assume they are both releasing the fumes inside the chimney. In some cases, the venting pipes continue separately up the flue. Joseph, if you have two vent pipes entering your flue, there is a chance that both pipes continue separately up the flue and out the top. If that is the case, you may be able to use the existing hot water vent system. When you look at the top of your chimney, do you see two terminations coming out?
Question: How does very cold intake water affect performance
Answer: Sorry to contradict but the temperature of the water going into the water heater will definitely have an effect on the temperature of the water coming out. the water heater needs to provide enough BTUs to heat the volume of water that you need to the water temperature that you want. If the water starts off at a lower temperature it will take more BTUs to get it to the temperature you want. This unit claims to be able to provide 6.6 gallons of hot water per minute but that assumes the water is startling an average temperature. If you have a modern shower head it will only use about 2.5 GPM but if you have second shower going, a hot water faucet open or a clothes washer filling at the same time you will run out of capacity quickly. Rinnai should have tables on their website that shows the ability of the unit to heat water at a variety of starting temperatures to a range of hot water temperatures at a given flow rate.

User questions & answers

Question: How many BTUs
Answer: The expansion tank for this heater is not required. Most people already have these installed in their homes but if not then it would be Ok without it as there is a pressure relief valve on top if something happened. GlobalTowne is an authorized Bosch distributor.
Question: What recirculation pump will work with this heater
Answer: A standard flow shower head is around 2.5 gallons per minute. A low flow head is around 1.5 gallons per minute. The recovery rate for a 90 degree temperature rise is 6.8 gallons per hour! So even the 7.5 gallon unit would only provide 4 minutes of shower time before the temp dropped off dramatically. (even at the low flow rate..)
Question: What is wi-fi ready means and what what will you use it for ? also what circ-logic capable means? do you need recirculation pipe for it
Answer: If your bathtub is bigger than your main heater tank, this unit isn't going to do much for you. It will add 2.5, 4, or 7 gallons to the capacity of your main tank, depending on which Bosch unit you buy. The 7 gallon unit requires a specially wired circuit. You will also get a little bit of lukewarm water that was in the line between your main heater and the Bosch unit. Unless your main tank is awfully small and your bathtub massive, the 4 gallon unit should work for you. Maybe a demand type thankless heater in your bathtub hot water feed would be a better choice, but be careful to size it properly for your desired flow rate and temperature rise. Also a tankless is likely to require special wiring.
Question: Does this unit come with a vent kit? Thanks
Answer: When the tap is opened, the hot water in the unit flows out. The colder water that was sitting upstream of the unit, enters the unit to be heated. If the tap remains open, the newly heated water flows out, being replaced eventually, (depending on the distance to the main water heater), with the water from the main water heater. You will probably set the unit temperature to equal the main water heater temperature, if you want to keep a constant temperature, but other scenarios are possible.

Question: Difference between rucs65in and rucs65ip
Answer: Rucs65in works with natural gas. Rucs65in works with propane.
Question: When installing in a garage is this considered an indoor install

User questions & answers

Question: does anyone have long periods of cold water when adjusting the water temp while showering
Answer: Our brand new unit takes about 5 minutes to get hot water to the furthest room in the house and then I turn on my shower and then the sink water gets cold.
Question: will there be enough water for 2 or even 3 people taking showers at once
Answer: I live in eastern Massachusetts and this winter was exceptionally cold. This model was set at 120 degrees and easily provided hot water for 2 showers and the dishwasher at once. I am confident that it will handle 3 showers
Question: Can we use the same vent which is used with the old water heater tank. Outside roof vent cover can be used same existing
Answer: No. For this unit the exhaust is inside of a 2nd wall that is the fresh air intake Your old vent is also not big enough in diameter.
Question: If I get a bit too tipsy and pass out in the shower and wake up six hours later will I still have hot and toasty water
Answer: Yep. The water stays hot as long as you keep running water.

User questions & answers

Question: does it come with isolation valves or do you have to order seperately
Answer: This model does come with isolation valves. Thanks
Question: Is warranty void automatically when buying this way? The warranty appears to be void if not purchased by an "authorized dealer
Answer: MyPlumbingStuff is an "Authorized RINNAI Online Reseller". Warranty is valid when purchased through us.
Question: Will this item work with propane
Answer: you would have to change the jets -read the specs-you should be able to order it for either natural gas or propane
Question: I just purchased a new house that has two of these units and it takes about a minute for water to heat, can that be sped up
Answer: Hi Jay, Understand that you have cold water in your pipes that has to be pushed through to your open faucet and discharged before the hot water can get to you. Your Rinnai instantly starts heating your water when you open the faucet but there is all that cold water in the way. The closer your faucet is to the unit the sooner you get the hot water. If you are concerned about water waste, use the cold water to start scrubbing your sink or tub and then rinse with the hot water when it purges the cold sitting there. Your Rinnai saves you a ton of money by being on demand so be patient. Brush you teeth in the cold so no waste also. It is a great unit! John and Joanne

User questions & answers

Question: When installing this with the Ubbink horizontal concentric kit is a condensate collector needed in addition to the 12 or 21" kit? Finding mixed result
