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:	Is it necessary to connect an expansion tank to this heater (for safety purposes)? It states something to that effect in the user manual
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:	would this be able to supply a shower
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:	Can be used "in-line with a large hot water source"? Would it help a large bathtub that runs out of hot water before it gets full from main tank
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:	When this heater is connected to the hot water line, what happens with the cold water that was sitting in the pipes
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.

Bosch ThermoTechnology

The Bosch Tronic 3000 T point-of-use electric mini-tanks are available in three compact sizes, which can be wall-hung (bracket included) or floor-mounted. They fit easily under a sink, even in a cabinet space, and because they have a sleek and attractive design, they blend in seamlessly with existing decor when installed in a visible location. Simply tap into the cold water line and install the water heater directly at the sink to provide hot water. Great for a wide range of locations!

Water Where You Need It

Provides hot water quickly at point of use and comes with temperature /pressure relief valve installed - 2.5 and 4 gallon tanks feature a simple 120 VAc plug-in connection (1440 watts).

Quality for Long-Life

Thick CFC-free foam insulation for maximum energy efficiency, glass-lined tank for durability.

Great for Small Spaces

Water heaters are compact and lightweight and can be floor, shelf, or wall mounted (except 7 Gallon) - features a sleek and attractive design to blend seamlessly with decor.

Minimize Wait Time for Hot Water

Waiting for hot water at a sink located far from a primary heating source can be frustrating. Only having access to cold water from a sink is just not useful, and plumbing a hot water line to every sink in a home or business requires time and money. To get hot water where it’s needed, when it’s needed, a better solution is to use the Tronic 3000 T from Bosch: a point-of-use electric mini-tank heater. This heater can supplement a primary water heating source, or be used under a single sink. In fact, the Bosch Tronic 3000 T can be used for three different applications: as a sole water heating source for a single sink, as a supplement to an existing heater located far from the sink, and as a buffer installed in-line with tankless water heaters that experience intermittent cold water, also known as 'cold water sandwiching'. No matter the configuration, there’s minimal stand-by loss from this premium mini-tank water heater.

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.

Product description

This compact , yet powerful unit - with gas inputs up to 140,000 BTU per hour - can meet all the hot-water needs of a small to medium American home or apartment. Designed to virtually do anything a 40-gallon tank-type water heater can do and much more The Wall mounted Excel Pro is design to work with hydronic baseboard or radiant floor heating applications, as well as provide domestic hot water to plumbing fixtures and appliances. LCD Display Control: Just set the desired water temperature The Excel Pro has an energy factor of 0.84-0.85. Excel Pro: Modulating Technology Tankless water heaters can be further divided into two categories according to their heating capability: "full on/full off" versus "modulating". Full on/full off units do not have a variable power output level; the unit is either fully on or completely off. This can cause an annoying and possibly hazardous variation of hot water temperature, as the flow of water through the heater varies. Modulated tankless water heaters change their heat output in response to the flow rate of water running through the unit. The Excel Pro comes with a display panel where you can set the output temperature and regardless of water flow the unit modulates the fire power.

User questions & answers

Question:	I'm having trouble finding the remote priority controller. Can you provide informatio on how to order it for this model? also cant find on excel site
Answer:	This model does not come remote priority controller any more
Question:	Does unit require fresh air intake
Answer:	Yes , all gas appliances require fresh air for combustion
Question:	Are the fittings USA standards
Answer:	Everything is standard but the threads on the natural gas line were not tapered enough for a standard 3/4 pipe fitting but there was a brass fitting included in the package that reduced to 1/2 pipe and all I did was put a reducer on that to get it back to 3/4. This unit is a super water heater. Better than our old Rani.
Question:	How far from combustibles does the vent pipe have to be? I plan on going through block foundation but worried about vinyl siding above it
Answer:	Vinyl siding is made of PVC . PVC is incombustible and the heater is so efficient that only 10% of the heat is gone in the form of water vapor are about 220 F, not to affect PVC.

User questions & answers

Question:	Is the water temperature regularated at the showers' manifold or at the tankless heater
Answer:	Both. The maximum temperature is regulated at the tankless heater. You control the shower temperature the the shower controls by mixing in cold water to the hot
Question:	Any problems installing over a clothes washer?, it's in a garage on an outside wall (10ft high
Answer:	Should be no problem, since it is high efficiency, just vent both directly outside with pvc and a screened downed turned elbow, they are already the proper distance apart for min clearances of each other. Exhaust needs to be min of 8" from window or door.
Question:	What is the ef on this product? looking to get one with 0.90 ef or better. i did see it is energy start
Answer:	1.0
Question:	Is 6.6 gpm adequate for showers
Answer:	Should be more than adequate for multiple simultaneous showers (depends on type of shower head, temperature you like the water, etc.). I often shower while the washing machine is running with no problems. This unit has performed well for us.....hopefully it will be durable as well (in service about 7 Mos so far).

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.

User questions & answers

Question:	my Marey 10L is missing metal top vent, only the black plastic which does not fit any of the available vent pipes. Are the adapters available
Answer:	Dimensions are approximately 9" in diameter by 12" tall.
Question:	hi can l install it outside on th e home
Answer:	I'm no expert, but I bought this for a modified commercial water heater for my greenhouse, which we turn up to 190F on the days we use it, consists of 2, 50 gal water heaters, circulation pump, aquastat and this tank which absorbs some water and pressure, BC water expands as it heats, theory is to keep pressure a little lower. Now my other pressure tank is a different model, much larger, it's on my well water, is only cold, and I believe it helps to maintain pressure in my water pipes so the well does not run continually. But IDK, they may be the same thing, used in different ways, for different purposes.
Question:	sealed combustion
Answer:	Mine was a replacement for a leaking tank so I didn't need any parts. Just unscewed tank and screwed new one on. You do need a bike pump to pressurize the tank.
Question:	Why does the burner ignite only on the lowest water flow
Answer:	While some manufacturers require installation in vertical position Watts installation allows for horizontal installation however you will need to provide support for the tank if installed in a horizontal position.

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:	Can I use the existing 4 inch galvanized vent pipe for the units exhaust
Answer:	Rather than trying to that find a vent stack I just installed it outside. It worked great for a while until we got a freeze and then it ruptured inside.
Question:	I m looking for the unit i can use off grid, is this the one? I understood the one i want is powered by battery
Answer:	Hi Craig,Thank you for your question. The Marey 10L is made for indoor use, and the warranty does not cover outdoor installation. Kind Regards,Ross GadgetsGo
Question:	Can I use 20lb propane gas for this heater
Answer:	No, they use a standard draft flue. HOWEVER they are incredibly dangerous and Marey will not support once you buy them.
Question:	Can I use the exhaust from the old tank type water heater that goes out through the roof? Or what do I need
Answer:	It is most likely because you have low water flow/pressure, if you are feeding this with a pump you may need a bigger pump, I f you have a filter system on your water supply perhaps its plugged?

User questions & answers

Question:	My plumber is looking for the exhaust venting for this tankless hot water heater.. Pipe for exhaust, 90 degree iPod, gasget? Help
Answer:	The exhaust pipe in the manual is this one https://www.amazon.com/gp/product/B00ED10Y6C/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
Question:	Will this suffice for a 4 bathroom home in Dallas? Looking at temperature rise of ~45 degrees (110 desired minus 65 groundwater temperature
Answer:	It's 10 gal/min... if you have a shower that is NOT a water saver and uses 6 gal/min... someone is going to miss out, no problem on the 45 deg rise, but we find that 130 deg is more desirable and still no problem in Albuquerque where the water temp MAY go into the 30s but most likely not less than about 45... HTH
Question:	Where is it manufactured
Answer:	JAPAN by one of the best hot water heater manufacturers in the world. Few if any can compair with Takagi, IMHO! Best unit I have ever installed, bar-none!
Question:	what does "condensing" mean in this case
Answer:	I can't stop laughing after reading the answers + there are 11 people with less clue who found the "explanations" useful... Guys, please allow me to explain the process: The condensation units have a secondary heat exchanger which takes the exhaust from regular 80% efficiency and "works" the water again in order to heat it even more, while cooling down the exhaust. Doing so the exhaust will be cool and it will condensate. This condensed exhaust will run down the vent and is gathered in an internal tray from where it goes to the condensation drain. Under NO CIRCUMSTANCES is the condensed exhaust in contact with your hot (or cold) water. By re-using your exhaust (hot), the efficiency will show on paper an additional 15% -17% added to the standard 80% of a conventional water heater.

Question:	I've had this unit for a couple of years. Why is it making a whining noise
Answer:	Hi, We do offer a specific vent for this unit. We advise customer to use stainless steel. Using stainless steel vent for our residential and commercial tankless water heater installations are required by code and we have to follow these protocols for safety. Proper vent installation is a MUST to help protect the heater from corrosion damage, but most importantly it is required by code to prevent gas leaks in the exhaust vent.
