    A few things that Matt forgot #1 gas line sizing for a 200,000 BTU piece of equipment #2 recirculation lines add to your gas consumption, they don’t stay hot for free. #3 contacting the gas utility about the added load (The gas meter and regulator will need to be sized for the entire house load , all gas appliances). #4 connecting a 200,000 BTU stationary appliance with a flexible connector may be excepted by Matt’s code enforcement district but it’s not a recommended connection by Rinnai. #5 as a gas utility technician we tend to find in 40% of the cases, the gas utility bill going up after installing a tankless water heater (this is usually due to added use because of the endless supply of hot water and the use of recirculation pumps with long pipe runs).#6 This Rinnai is a little easier than servicing the condensing type when parts are needed but it’s no walk in the park , you better know what you’re doing if you’re replacing heat exchangers and burners.#7 when it comes to tankless water heaters ,Rinnai s are very good but their service valves suck, install Webstone service valves and you can thank me later.
    When it comes to tankless WHs, Rinnai and Bosch are probably your best choices. I personally have a tank type, I keep it clean and replace the anode from time to time (less headaches and I don’t get paid to work on my own equipment but I love working on yours).

      I agree with most of what you said but remember that Tankless units do not consume 200,000btu every time they turn on. They are stage fired and gas consumption is proportional to the load. Conventional tanks are 100% on/off. Its very seldom that the unit is drawing 200k btu meaning 11gpm hot water. In most cases these unit are drawing 50k btu. with one or two fixtures running. I prefer Navien NPE series.

    I like getting info on new products. Unfortunately this video came out like sales pitch for Rinnai. I do not doubt it is a well made quality product but I expected to at least get a close up of the plumbing connections, information on how water is circulated (pump inside unit? small storage unit?) . Efficiency when in recirculating mode? More info on maintenance, restrictions on hard water usage, venting through the roof issues, and especially your knowledge and experience (pros and cons) but we didn't get that objective feedback this time. I had a friend that was all proud of his tankless unit and bragged how much he would save, until he needed to called the plumber back to service the unit each year. While he did have unlimited water, he had no real savings.

    I have a Rinnai commercial unit handling my heat and hot water. It was able to use the existing PVC exhaust from the old direct vent tank, and the relief valve was already run to a drain so that was fine for condensate. It's much quieter and modulates pretty seamlessly. It handles heat, a hot wash filling, and a shower as hot as I want it simultaneously without issue. The only real downside is the initial delay, but honestly it's worth the tradeoff for me.
    What I can't speak to is longevity, reliability, and service costs. I rent through, so that's not my problem (directly anyway).

    Couple things.. in a real world installation from tanked to tankless, the condensation drain isn’t really an issue, you could just utilize the drain pan line (I don’t see one in this video) for the purpose of draining the condensate drain and as a drain pan drain. If you install a condensate neutralizer filter you’re good to go.

    • @MyFortressConstruction
      @MyFortressConstruction Год назад

      Code doesn't allow that. Manufacturer says not to use any other condensate or shared drain as well. The issue is that condensate lines grow algae/mold (because people forget to clean them) and they can eventually get completely blocked. Not a big deal because you'll get a warning or the system will stop functioning, however, if your water heater ruptures, it's going to need all 3/4-1" of that drain line, and if it's partially blocked by algae, then it can't serve it's purpose and you can have overflow from the very drain meant to prevent it. So, go with a dedicated line for all condensate and drain pans. As a side note; a mechanical room I'm installing right now has 4 condensate lines, 2 TPR lines and 3 overflow drains. It's tempting to combine them, but experience/code says no.

    A more energy efficient option than using a recirculating pump it is to locate your water heater(s) closer to your faucets. This may be difficult for existing buildings, but if you are building new, then design your house to accommodate this. Install multiple water heaters if your faucets are far away from each other. Also, insulate both your hot and cold water supply pipes. This is especially important if you do use a recirculating pump.

I was torn between tankless (have the gas for it) and tank. Ended up installing two Bradford White 50gal power vents in series. So there's 100gal of hot water on tap, first hr delivery is approx 140 gal. It almost seems to work like tankless really. Can take a 20 min shower, then fill a jacuzzi tub, run the hot drip to keep the bath warm, do that for half an hr and then take another 20min shower. Solid hot water the whole time, faster delivery, lower maintenance. Pretty happy w it.

    Hey Matt! We've had a Rinnai here in South Alabama for 20 yrs, It is a great unit and has served well despite being installed by people who claimed to know everything, but knew absolutely nothing about tankless and really screwed up royal installing our system.

    A couple of things to add:
    (1) That cross over valve will be pushing your hot water through 1/2 inch lines. The difference between that configuration, and my implementing the 3/4 recirc line that I installed when building the house (but the plumbers had no idea how to utilize), was the difference between heating the water though all lines in 10 minutes, versus 30 seconds. It made THAT much difference. (Why, with a recirculating hot water heater, would you care how long it takes to circulate the water? Well, I'm on propane. We pretty much just push the recirc button when we want hot water in the downstairs faucets and bathroom, and turn it off afterwards. In other words, we don't set a schedule with the hot water continually running through the lines, to save on propane, because it only requires seconds to circulate though the house from beginning to water heater return. With the Rinnai Condensing recirc hot water heater, that brings our hot water heating costs down to maybe, $15 a month for a 2400 sq foot home. Anything you can do on a retrofit to create a 3/4" recirculation hot water line, will likely reduce your heating (gas or electricity) bill. It's not rocket science. Poke a hole out somewhere at the end of the line, and run that new hot water line over, under, outside, back to the tank. If your existing system has, for example, two supply legs, you can link them together at the end of both lines.
    (2) On ANY, and I repeat, ANY tankless hot water system, add a 100 Micron, spin down sediment water filter on the OUTBOUND hot water line, to catch any debris that may come from the hot water heater. With a regular tank, that sediment settles to the bottom of the tank, and the amount of carry out of the tank through the top hot water supply pipe is minimal. With a tankless system, there's no place for that debris to go, but to your fixtures, clogging them up. In a severe case (as in, with very hard water), in a recirc system, that debris can foul your check valves causing problems (e.g. cold water running back up the hot water lines, giving the customers at the end of the circuit, cold showers). Even if your water supply has great PH, Rinnai recommends (I believe) flushing the system with something like vinegar to clean the tank annually. (In my case, with hard water, it's every 2 to 3 months.)

    • @HoyaNinja22
      @HoyaNinja22 2 года назад

      The Navien already has a built in sediment trap on the incoming cold water line to the tank. As far as hard water you need to treat your system to prevent that build up and eventual corrosion of your plumbing system.

The spin down filter catches it, instead of your downstream faucets and other devices.

      We have very hard water in Utah. In 2010 we gutted our prior house, piped everything in Pex including a recirc pump and 3/4" recirc line. We installed a good soft water unit that fed into the Rinnai and have had zero issues. Soft water is vital in keeping the tankless systems free of build up. There is a company out of Florida that designs their soft water systems based upon your water hardness and impurities. We have moved into a 1977 home and are planning our upgrades to include Pex, Insulated Recirc Line, Recirc Pump, Tankless, Soft Water and RO. After living with clean shower doors and endless hot water, it is a high priority to upgrade and enjoy.
      Many of the better tankless models include recirc pumps and smart technology that learns the higher usage times and will run the pump accordingly. You can also integrate wireless switches and/or WiFi apps to turn on/off the pump making them more of a complete on demand system. For those without Recirc Lines, look into Aquamotion AMH3K-7N with the On Demand Kit and you can overcome the 5 minute wait for hot water in the 2nd floor shower.

I installed them the last time I flushed out the tankless unit, and though we're a month or two past the normal 3-month flush schedule which has kept us out of trouble, still no indication of scale problems in the water heater. I had to pull the strainer while tapping the line to supply a new irrigation system, so it's been without the SILPROS for a couple of weeks. However, thus far, I'd give them a thumbs up.

    After recirculating the water into the cold water line , you must be getting tempered water out of the cold water side of the sink . Tempered water after all is a mix of hot and cold and we were always told not to use the hot water to make tea , coffee or drink it because it contains metals from the heater . Heat exchangers leak for many reasons but if one of them is from cavitation where did the material that was removed to cause that leak go ( right into the hot water ) .

    Navien is probably the best unit out there, we have very little trouble with them. The A model the only one we sell has a small liter size tank that stays at temperature. This eliminates several things. 1. when you turn on your hot water, hot water is on its way, no time difference from your old tank type. 2. No cold water sandwich. 3.No minimum flow rate. If you have a modern home with a large hot tub, the tankless will not only fill it but will be able to replace the massive heat loss they incur when turning on the bubbles. Will you use more gas? Of course, good things usually do cost more. Gas meters, at least in our area are supplied by the gas company, just a simple phone call and they replace the meter free of charge. Never understood that argument. The warranty on a Navien is 15 years on the exchanger and electronic components are relatively inexpensive. Dont buy a combi boiler! This is the latest craze. Modern boilers have outside reset controls and modulate output at a 10 to 1 ratio. Take my home for instance, my heat load is 36000 BTUs on a zero degree day. With a 70,000 BTU boiler I can modulate down to 7000. But this turndown ratio is based on input, most Combi boilers are 200,000 in, this means a minimum firing rate of 20,000. That would be ridiculous.

    I have a tankless water heater that is 100% efficient: A Black & Decker 50 AMP electric flash heater. It's just my wife and I, so we don't need to run multiple hot water uses at the same time. We always take showers, so we only need about 1 gallon per minute. We can shower as long as we want, and it's temperature-controlled, so it's a steady 106 F. Best of all, the electricity costs us nothing because our solar grid-tied system has never generated a bill since we installed it years ago. It's small enough, we could install it right in the bathroom British-style if we wanted instant hot water. The cost: $168 at Lowes!

      If you're in America, electric tankless is only used for seldom-used points because they can't flow hot water for very long. If you're in other parts of the world, that's not the case necessarily. The difference is how they get power. In America we only have 220 volts. .. and that's if you run a dedicated line and if your service supports the extra amperage.
      In Europe you might have 440v, which lets you need less current, smaller/cheaper electric wiring, all while using a heater than can compete with gas for performance. In other words that product doesn't exist for Americans.

I opened the door and saw water at the bottom from a compromised tank. Recently I was awe of tankless systems as it would be easy enough to convert too right there. However, I planned to move out come that winter as my job was moving to another location, plus I know nothing about repairing a tankless system and I didn't have time to take courses on how to fix one. So I got on the phone trying to find plumbers that work on them and I asked, "just off the bat, do you charge more for fixing a tankless heater," and I got two telephone numbers for guys that work on them. I asked them, "is it more expensive to work on a tankless system?" and each of them said, "it depends". Well that answers that question. I was asking for a Y/N answer. So I got another tank system and put it in that same day. I was surprised I even considered a tankless.

      The valve allows hot water to reach the sink, but then closes. When you call for cold water you first flush a bit of warm water out before the cold arrives. A minor inconvenience, in my opinion, because it's the hot you really want. Those circ pumps are great for all homes where waiting for hot water is wasteful. The one I installed, a Watts brand, saves a lot of water in a year, important as I'm on a well.

      @@paulmaxwell8851 Thanks for your answer Paul, but I'm still trying to wrap my head around it. Normally a hot water loop has a dedicated line that returns to the hot water service and the cold water has its own line to the sink. In this case (according to the drawing) the hot supply and return are connected to the cold water line. So does the hot water return line (on the cold side) switch over to cold supply automatically within the hot water supply sending cold water back to the sink? If so, the warm / hot water in the return line would have to be flushed out before cold water would come out, is that right?

    Looks like a nice unit with the built in recirc. pump. A recirc. pump would not work well in my 50's house. The water heater is actually quite centrally located with respect to the hot water fixtures. However, there are two separate hot water pipe runs, one to the kitchen and the other to the bathrooms. The bathrooms are maybe 50% farther away than the kitchen, but the hot water in the kitchen is used more frequently. So where to put that single thermal bypass valve? I looked into the cost savings on water with a recirc. setup and it would take many decades to pay for the install. Maybe if the local water utility had a decent rebate program (hint, hint!), then it might make sense.
    I went with a condensing unit for my retrofit install. Condensate was not an issue as the clothes washer and standpipe drain was right next to the water heater. Also, it was in a garage on a shared wall with the house. So venting out the wall wasn't an option. Was able to use PVC venting that ran up through the roof in place of the old tank venting. Also, the condensing model I chose could run on the existing 1/2" gas line vs. a non-condensing model of similar capacity would need a new 3/4" gas line run.
    So it's always best to look at the entire install and consider the whole system cost. In my case, what was saved on gas piping and venting could be put towards a more efficient heater and with the recent rise in natural gas prices, that's paying off big. Going tankless cut my gas use and bill by over 80% compared to the old 40 gal. tank.

      It only warms the cold side up slightly. With a tankless, the hot line goes cold quickly (like a normal tank), but the lines inside the tank are mechanically cooled to air temp. This mean that when you turn on the hot tap, the heater has to heat up the pipes and the water which simply takes longer than a tank as the tank line is already filled with hot water. The circulating hot water idea is how hotels have hot water at any tap on any floor/room within 3 seconds. Yes, it wastes energy. And yes, I have a tankless unit which I love, but I do not have a circ system which I do not need.

      Both can be selling points.
      This system does not use less energy to run, but you get that from the get go being non-condensing.
      The only way this could reduce energy impact is if its cost is low enough and the size of the house is large enough to have multiple installed so the hot water runs are shorter. Condensing would still be more efficient, but if the cost of this is lower, it may be an okay alternative for someone on the cheap side (course if they have a large and poor layout - they should have enough to pay for condensing or there's can fix the layout.)
      The recirculating only fixes long plumbing lines, it is only a good strategy if water conservation is more important that the fuel and efficiency there, which is sometimes more geographic to decide there.

    About 15 years ago we had a tankless, Bosch I believe, but went back to a tank for the following reasons: 1) After two years of use, the repair tech was not able to get it to start properly (propane)... the burner would fire up for a couple seconds and then fault out. Performing the regular recommended flushes/cleaning did not help. 2) Could never wash clothes in hot water. The washer would fill using several calls for hot water. Every time the water was shut off and then turned back on a few seconds later, the tankless would re-start its heating process, putting several seconds of cold water in the hot water circuit. The unit we had did not have any way to keep heating after the flow was stopped. If the flow stopped, the heating stopped, completely. The end result was that the washer never washed in anything warmer than luke warm water.
    What did I like about it? When it was off, it consumed NO gas, period. As long as it was running and I had propane, I would never run out of hot water. I was able to select the exact desired temp for our shower using the remote... this way, cold water was not used at all to lower the temp of the hot water down to the temp that was comfortable in the shower.... We LOVED that feature.
    The only way I would return to a tankless is if we could overcome the on-off cycle problem we had with the clothes washer.

My recent research suggested that some of the newer tankless have a feature that allows you to keep the heater running for 1-2 minutes after the water flow stops, in order to combat this exact problem without having a hot water return loop. When my tank heater starts giving out (electric) I may just give tankless another try... that is after I verify that it will stay running for a period of time.

      If you put in a recirculation pump with a heat pump water heater you will need to use a smart control to prevent the pump from running all the time and causing the tank to cool down. Rheem has a technical bulletin on the problem. The Smart Recirculation Control solves this problem for HP water heaters.

      There's no way solar panels on a basic home scenario could provide anywhere near enough electricity to power one of these bad boys. Maybe you need to think about solar on a net major grid level which wouldn't involve the hot water heater industry at all.

      This is kinda why I am afraid to go all electric in my house. I keep hearing insiders warning that the grid is becoming overloaded in a lot of areas. Here in the area where I live we have experienced a commercial growth spurt and the energy consumption has doubled. So the energy company has added a huge solar farm a few miles from my house to compensate for the uptick in energy usage. Until I see the solar industry working out the last few kinks and I have solar installed on my home I am in no hurry to electrify my house.

    Any user comments about those valves you explained and how local hard water effects them?

I am curious though about what interval or how long that jumper valve will be effective. FR
