how much gas does this use at when running. How many CCF. I currently have a 80 gallon high efficiency hot water now. Can I use this connection or do I need to run a 3/4 in gas line directly from the meter?

The Rheem water heater uses 199,000 BTU or about 200 CF or 2 CCF. The Rheem installation manual is available on the Rheem web site. On page 53 of the manual, the manufacturer lists the minimum NG pipe size as 3/4 inch diameter. Typically, a tank type water heater has a 1/2 inch supply line that is reduced from a 3/4 inch or larger main supply line. So, you will need to replace the smaller gas line from the original reduction point to your new Rheem tankless water heater.

Hello J. Taneri, I've never really pumped any distance with mine the only info I could give you is what I have done with mine-I've pumped from a stream- with the pump drawing the water from about 8 feet down to a barrel in my Jeep and the discharge hose is app 12 feet long. It took awhile to fill the 55 gallons maybe about 3 gal per minute. Maybe I was over exerting the pump the way I was using it??? I failed to prime the pump one time i got too impatient and burned the impeller. I got a replacement and it works fine again. any other questions please ask. jerry mayers Hello J.

I have mine connected in Series in the following sequence. Gas Mains to house, to mains regulator, to various gas appliances including a plumbed in gas grill. The hard line then exits onto the deck where I next installed a stop valve and then the GASAV then via fittings and a flexible hose to my grill.However, this stopped working about a month after installation. It is permanently stuck at 15 mins.

I have 1/2" supply line in the house from the meter to the stove. I put a T at the stove and ran a 48" 1/2" corrogated gas line to a 1/2" ball valuve and then to the burner. I have all the BTU's that I need, It roars like a mini jet. It is large enough for resteraunt wak cooking! (Chinese cooking)

Yes, You probably have your HW tank far from where you want fast hot water like I do. if supplied from hw side it will just give almost instant hw. won't hurt a thing, just save on your E bill.

I don't know that I agree with him. My bills appear to be rather even in so much as my electric bill went up because of using the electric water heater, yet my gas bill went down because I'm not keeping a tank of hot water constantly heated using gas. I use gas sparingly even in the winter with heat. I like to keep it pretty cold but use electric space heater's in the rooms where I'm actually living. I live in a small condo so I was glad to have the extra space that isn't taken up by a large water heater.It gave me space for a mop bucket brooms etc. Hope this is useful to you

This isn't an answer to the question, but rather a repeat of the question and a response to the previous "answers." Mr/Ms Roby, if you don't understand the question, why did you write an answer? Ms Cowgirl, the Product Description says, "This amazing instant water heater can be connected to the existing hot water piping." So perhaps a better explanation is that YOU cannot hook it up to American piping. If NO ONE could hook it up to American piping, it wouldn't have a 4.4-star rating. Mr Curcie, what difference does it make WHY Ms O'Meara wants it hotter? A shower is not the only way people use hot water. Folks running a food truck, for instance, might need hot water over 100 to make hot tea, instant coffee, wash their utensils, etc. Using the example in the Product Description, tap water coming in at 56 will be heated 45 to 101. This is NOT hot enough for hot drinks, as 101 is only 2.4 above body temperature. Great for baby formula; not great for coffee. If the 101 water from one unit can be run through a second unit, a 45 temperature rise will yield 146 water, which IS hot enough for coffee and hot tea. The biggest problem with Amazon's Q&As is people chiming in with "answers" when they don't really know the answer. So how about it? Does anyone (including the seller) actually know the answer to this question? Or are we supposed to be satisfied with "I don't know," "I don't understand," "I could only guess," and "Why would you want to?"

We do not have natural gas in the rural areas in the foothill. I connected my BBQ to an axillary line used for my homes propane heat,and Kitchen stove. The Quick connect and disconnect is on our back Deck for my BBQ.

you circulate a small amount of water back to you water heater with this unit so like me you are thinking you are reheating or making your water heater run a little more, which you are, however, if you run your water at the faucet for a minute or more to heat it up, you are also bringing in outside water into the water heater which is much colder than the water that is recirculating causing the water heater to run anyway and possibly longer depending on the incoming temp of the water and how many gallons you run to get the water temp to what you need. If water conservation (cost or availability) is an issue (which availability may soon be the overwhelming issue for all of us) then this is the way to go. cost is very minimal. If you use very little water, and your other faucets / showers are close to the heater and heat up within 4 to 6 seconds then I would go with a 2.5 gallon under the faucet water heater, or better (if you can afford it) is an "on demand" heater, either way you have very hot water instantly. I have both the laing circulator pump at work and an under sink water heater at home. Both work great, just depends on your needs. The laing was installed at work to conserve water (trucked in 2 times per month) and because it circulates (85 deg on and 94 deg off) it keeps the water line thawed out and just a little natural gas is WAY cheaper than electricity or the water we truck in. At home, we want very hot water at our faucet (zero loss of water) and our other faucets heat up quickly so no real loss. Love them both. The Laing and the under sink heater (storage unit) will ultimatly cost the same (installation and parts are offset). THe Laing gives 95 degree water (the hot stuff follows pretty quick, the under the counter is instant, but either one makes your life nicer and you no longer have to sit by the faucet. I have since installed both systems for friends after evaluating their needs.

Jerry I purchased mine for additional heat in my shop that is attached to my home , I also attached it to my 500 gal L.P. tank but you will need a regulator placed on that line , do not go direct from the tank with- out one !!! Note there is a slight smell , for the price it works great . any other questions contact me .

This heater will make hot water until you run out of gas. I would estimate for a couple thousand gallons from a 20 pound propane bottle. Should be easy to hook up to a garden hose with an adapter. If you use the hose for the hot water side and make sure it is rated for hot water use .

I am not sure about that. You would have to ask a plumber. You have to have a licensed plumber to hook it up bc it is gas. At least that is the rule in this state.

Not sure but we heat the hot tub frequently from 68 to 101 and in Nov the pool from 68 to 89 and I haven't noticed a huge difference in my gas bill. It ranged from Aug at 24 ccf, Sept 24 ccf, Oct 24, Nov 84 ccf. The bill amount ranged from $35 to $85.00. Charged at $0.60280 a ccf It heats up quickly also, Hope this helped!

I'm a bit unclear: These pumps simply circulate the hot water through a "runaround" circuit, so that you have instant hot water when you turn on the faucet, shower, etc. Once the faucet, shower, etc. is turned on, then the house pressure delivers the water at whatever the pressure is in the pipes. So, my question is: for what purpose are you using the pump that you require 3-4 gmp?

I don't know what that means. To activate, this unit requires a minimum flow rate of 0.15 gpm. The only effect of this for us has been on our dishwasher, which fortunately, has an internal heater. Otherwise, we have noticed no performance difference between this heater and our previous, tanked, heater. Except, of course, that we never run out of hot water anymore and our gas bill has gone down by about 10%.

I'd strongly suggest a higher capacity pump if you're using a vacuum chamber. I'm using this pump (1.5cfm) on a 1 cu ft chamber, and it takes six minutes of pumping to get down to a useful degassing vacuum. It's a problem when the liquid in the chamber has only a 20 min pot life. A 5cfm unit isn't that much more expensive.

You definetly need a 3/4 in. Gas line connection to this device because it runs at a maximum of 199k BTUs which a smaller line won't put out. The size of the gas line at your meter is determined by the number of appliances and BTUs the whole system requires.
