Hi Ess Dee,

Thanks for commenting. You can use the same silicone seen the in video to seal any gaps or crevices you feel moisture or air may penetrate.

I observed an obvious gap between the vent tube and the exterior wall flange. What did you use to seal that gap?

Depending on your location, there are gas company rebates, federal government tax incentatives, energy conservation and efficiency ratings that will offset much of the cost. As far as PEX plumbing is concerned, if you can unroll plastic tubing then you can install it.

Standard sheet metal venting will not be able to withstand the heat generated by tankless units. Also roof vent cap needs to be replaced.

Electric tankless units require thicker gauge wiring and an upgraded circuit breaker. I would recommend, if possible, an attic installation.

I have a different problem and really would like some help. I moved into an all electric house but found out during the cold months, my shower just didn't have enough hot water. I found out when I bought this house, it had only one small electric water heater so I had someone put in another small water heater. One which was the orig is near the kitchen sink and the other is near the bath. It works as I do have hot water now but with a small house that I have, I need the room. How does this tankless work in a house with no basement, two small water heaters in different locations and being electric to? Thanks for any info or help.

We bought this house in 07,the hot water heater was over 25 yrod then,If I had an extra $250 I'd replace it. Why should I spend $800 to install a tankless? Has the price droped to a more competive price?What I maybe interested learning is PEX plumbing,I'm sure I save money with that project the pluming is a plate of string noodels!

Our new house came with a tank less (Noritz) water heater and I'm split either way on favorability. The pros are that you save a little space. So far the bills are about equal to our last house. The cons, the kitchen sink is about 50' away from the heater and can take upwards of 8 minutes to get hot water. Otherwise the rest of the house receives adequate hot water in 1-2 minutes. This house also has a backup electric water heater and a circulation pump. We keep these off to keep the electric bill down. Has anyone ever installed an “Insta-hot” below a kitchen sink? I’m looking to add something to get hot water quicker to the kitchen sink.

Do you need to re-pipe? What is your electric bill after the installation? How big was your unit? How many people in your house hold? Do you experience the drop of hot water when someone else turn on the hot water from other place --- kitchen sink or bathroom faucet? I like the space saver idea but will wait for your feedback before proceeding.

In most states (if not every state) the installer MUST pull a permit with the authority having jurisdiction (the city you live in or rural water supplier) BEFORE starting any work to pull or replace a water heater. The installer (including the home owner) MUST conform to the local plumbing codes. This also includes gas pipe sizing.

I would never own one of these units. If you have hard water, you could void the warranty. The flow of hot water from these units fluctuates if for example, you were taking a shower and someone ran hot water from a sink, you could experience what is called a sandwich. These units take getting used to in the long run. Finally, they are very expensive. A dealer installed unit could run you $3,500. This includes, plumbing, gas lines, equipment costs, etc. Yes, they are energy efficient and you can get a substantial tax credit from the fed's presently. Someone mentioned electric. Ouch. A single unit could draw 80 AMPS. You probably don't have room on your panel. #2, the electric company will charge you if they have to upgrade your service wire and transformer. Not a good idea unless you install a point of use unit (120 V). I installed a lifetime Marathon water heater. Best storage water heater on the market. End of story and plenty of hot water

There seem to be some pros & cons here... I rent & my land lord just put in an electric water heater. He had one heck of a time takeing out the old one because of all the settlement. It took 3 guys to get it out of the basement. The old tank had never been drained in the 10 years

I am planning on switching to a tankless. Its in the back of the garage and there is no access to and outside wall. Can I install the vent through the ceiling just like my water heater has now? Its a long run to the master bath and the original contractor put an electric water heater in my wardrobe closet, I want to remove this water heater, then install another tankless in a fabricated shed outside on my north wall, then install an isolation valve under the floor with an access panel, then I could have the rear unit supply the master bath with the shower and Jacuzzi, and the front unit supply the kitchen,and another bath. I figure with isolation valves if either unit shut down I could use the other unit for the whole house until fixing the malfunctioning one. Seems like water heaters always break down at night.

Nice job Ron. I was thinking of installing a tankless water heater myself but am wondering about the cost related to a complete installation. Is it possible for you to provide the estimated cost to your projects? This would help in my decision making. I perfer having the finances before proceeding with any project.

Outstanding! I have been toying with the idea of doing this for a couple of years. I have asked a lot of questions but never got to the point where I was ready to do it. Now I will thank's Ron.

Hey Ron-- Wondering how you got an air-tight seal on the exhaust pipe through the flange? It appeared that I could see light from the basement when you were installing the exhaust pipe through the flange.

I too always heard that flex piping can only be used in short sections especially for use behind moveable appliances i.e. gas stoves. i was plagued by the same dip tube problem, and i found a website, www.diptubesettlement.com that reimbursed me for a new water heater as well as any damage caused by the deteriorating plastic. it will be worth looking into, and i'm not sure theres a timefame for claims.

with the gas inlet to the heater-- a pipe union is used, am not sure if that is allowed to be installed indoors in all states, unions have a reputation of leaking, it maybe ok to use unions outdoors, it would be better to use compression couplings for maintenance purposes. IMHO.

I see that this must be an old video. You used a Ridgid cordless drill-driver with an old nickel-candium battery. I see the orange store-the only retail place that sells- now have lithium batteries. I know that the lithium batteries work better and will buy 2 new batteries AND charger when the lottery pays me. Ridgid has written me that the new batteries will work with my old drill and the only saw I own. I see you did not use the Ridgid recriprocal saw.

1) Before installing a tankless water heater you need to verify the gas meter can handle the increased flow. 2) Some recent articles are questioning the return on investment.

What is the secret to sizing the unit. I've known 2 different Friends that had to turn on the sink hot water full, to keep the shower temp. constant. With just the shower on the temp.would fluctuate. But that was 10 years ago,has the heaters improved to fix the problem ?

You left off a very important part of a tankless install. That is a set of isolation valves so the unit can be periodically cleaned. These are important enough that the manufacturer Rinnai includes them with the unit. These units can scale up quickly and need to be flushed with vinegar. You are also required to ground flexible gas lines in most states. In NY not grounding Trac Pipe is a code violation. I would have used 1" trac Pipe on this installl if I used flex pipe at all. I prefer black pipe on a Tankless install.

Very nicely done, overall. One small correction. You are not supposed to use flex gas line for more than a 3 foot run on these units. Flex 3/4 line is slighly smaller than hard pipe and the corrugations slow the gas flow somewhat. These tankless heaters are monster gas eaters when they run, and are easy to starve, if you are not careful. I installed mine with flex and it worked fine for about 8 months and then started failing to ignite. The problem was that the starved heater was burning to rich and carbonized the flame rods. I had to go in and clean them, and replace all my flex with solid gas pipe. I have videos of installation, flex hose replacement and burner cleaning all at HowToLou.com. -Lou

I'm installing one of these and I'm not a plumber but IMHO, it appears that they put the gas shutoff valve in the wrong spot. How can you clean out the sediment trap if the gas shutoff valve is downstream of the trap? Also, it would have been a good idea to put bypass valves on the unit to aid in flushing the heat exchanger.

Thanks for the video and writeup on the tankless water heater install. I'm getting reading to install a new tankless unit so the information has been very helpful. One of the difficulties I'm having is dealing with the venting from my basement. It's very similar to what you've shown in the video. The problem is that everything I've read (including the manual for the unit you installed) says do NOT extend the exposed vent pipe outside of building. They say you must terminate it directly when it comes out of the wall. I'm not so sure the raised pipe with the dual elbows outside is allowed. However, the vent must be at least 12 inches above the ground or snow line. So if you can't extend the pipe vertically outside then it's not possible to do horizontal venting in a typical basement because it would be too low. That would only leave vertical venting through the roof. Do you have any additional insight on this?
