Awesome video, I did this back in 2020 after my 30+ year old gas water heater failed, dumping all over my laundry room floor, and we replaced it with a Rinnai tankless gas water heater installed on the outside of my house due to S. Carolina building codes, and the igniter, and electronics run off 120 volt, with the cord simply running through the wall inside the house into the laundry room, and sharing the same outlet as my washing machine to make the job easier. Only downsides I've had with the tankless is it takes a little longer to get hot than a tank heater, and DO NOT take a shower when the washing machine is running, and it wants water at the same time as the water temps will be all over the place. HOT HOT OUCH!!! 🥵

Very clean job and solder joints look very good! However, instead of an FIP, you should have put unions for easy disconnect in the future when you swap out units or so you can flush the tankless. Or, you could have put shut-off valves and two tees between the valves and the heater for the flushing purpose.

I like to use a slightly lesser kick in the EMT, so that there's a tiny airspace between the tubing and the wall. I feel that helps prevent the tubing from corroding, since concrete does pass/hold moisture.... Naturally, there will need to be small shims under the straps to maintain tightness with the EMT (and use more straps, and space them a little bit closer together).

A plumber I spoke to told me the cost for a tankless (including installation) would be around $3,000 which seemed kind of pricey to me. DYI installation would obviously bring the cost down, but I’m not sure if I should be messing with gas!

The tankless water heater looks fairly small to me. Does that water heater supply enough hot water for a two bathroom with a washer? How do i figure how what water heater i need for my home?

@user-nc7oh2rn7f Жыл бұрын

It's not about the size of the house. Tankless heaters heat the water as it goes through. As in, it isn't heating water unless you have a tap running somewhere requesting hot water. So what you need to determine is how many faucets and/or appliances will be using hot water at one time, then you can decide how many gallons of hot water you'd need per minute, which is how the tankless sizes are set. So if you run your dishwasher and two showers at the same time, you'll need a pretty powerful tankless unit, like 9+ gallons per minute. but if you are only running hot water in one place at a time, a much lower powered one might suffice, like 3-6 gallons per minute.

I know number 6 wire you needed minimum three-quarter inch conduit. That said, there was still plenty of room for movement inside the conduit for the 120-volt circuit. I'm no fan of PEX. Many years down the road that material can possibly dry out and crack. The copper will last far longer and you also have the benefit of copper as being a antibacterial metal

I saw a youtuber make a custom water tank that acted as a (500 gallons) heat battery. Its far more efficient to have a tank of heated water then a tankless water heater. And the bigger the tank the better the savings. You have to put so much energy into water to heat it. To take 3 gallons to boiling it takes me around 30 minutes on electric stove. But if i started with hot water the time is half. Water will obviously get hot faster if its mixed with hot water first. I could make a tankless water heater work. Id get a pressure tank and set it in front of the tankless water heater then let that get to room temp in the house. That way at least the water is above 60f when it goes in. I could also just paint it black and place it under a skylight. But like i said just upsizing your water heater will save you money. The only reason to go tankless is you would rather have infinite hot water. Like oh ill just run this for an hour. If you really want to save money lol get a wood stove and a copper coil 😂😂😂

I really want to install a tankless, but the electrical portion of it is the biggest hurdle. Currently, the electric heater has a 30 AMP breaker, and I'm going to need two 40 AMP breakers. The path to the heater isn't nearly as direct as this and I have no idea if the wiring is being ran through conduit behind the drywall. If the electrical could be sorted, the rest would be a no-brainer.

In the place of some country where I live (prefer not saying it), electricity around here can be billed monthly or by topping up the balance of kWh just like internet data plan on phones. For the monthly part, usually some technician come to check something in the fuse box every month, hence the placing of the fuse box. I don't know what it is. All I know is just they want to see some series of number that's changed everytime by themselves. I don't bother to ask what's the purpose or what's the thing in the device they're checking on. Probably next time.

Different places have different building codes that change over time. I live in S. Carolina, and close to 15 years ago I inherited my grandparents house built in the mid 50's, and we had to redo the entire electrical system as it had various issues from age, and the norm back then was 2 prong outlets except 220v appliances, and even copper wiring was not needed for a house to be passed by building code laws, as they could have used junk aluminum wiring, but thankfully the builder for my house used copper, and smoke alarms were none existent, but I had to have them hardwired throughout my house to pass inspection. Also when I replaced the old gas water heater in my house with a gas tankless code was updated to state they could no longer be inside the house, so the plumber I hired to do mine along with some other plumbing work that was long overdue for my old house, had to put the water heater on the outside of my house, and ran a 120 volt cord through the laundry room wall into the same outlet my washing machine shares, yet the electric ignitor for my old gas tank heater was hardwired directly to the breaker box.

you should 1000% be turning off the WHOLE HOUSE POWER at the top of the breaker box. By leaving the main breaker on, the bus that you're working on is still powered up. This can be done without zapping yourself, but you REALLY shouldn't be taking risks with 100+amps, which can absolutely kill you. Everything else is okay, but that's just ignorant and stupid and could lead to an unwitting viewer getting killed.
