While you are saving $ during the day by stopping your tank from igniting, your tank is not keeping the heat long enough to kill germs. You are heating an hour before usage and shutting off before you are done then leaving it below ideal temperature for most of the dayAvatar wrote: ↑ My fix is to get a bigger tank for more hot water (still not unlimited). One I have is an electrical start with a plug in to the wall outlet. We usually needs hot water for shower and washer from 4pm to 10pm. Go to work during the day. So I installed one of those smart outlet and set it to turn on at 3pm and turn off at 9pm. Works perfectly. Wake up the other morning at 7am still have hot water.
The tank is mainly for showering. And by the time it heats up after an hour what else is left? I believe the water bottle you are taking with you got more germs than that. And it still hot (probably 80C) after 8 hours.bubuski wrote: ↑ While you are saving $ during the day by stopping your tank from igniting, your tank is not keeping the heat long enough to kill germs.

NG is cheap don't risk your health.

You can get legionella by inhaling contaminated water droplet while showering, it is in the link I posted. I also doubt the water in your tank is set to 176F.Avatar wrote: ↑ The tank is mainly for showering. And by the time it heats up after an hour what else is left?

On the other hand we have an under the sink reverse osmosis water filters with UV. That's what you need to get rid of the germs you put into your body. And more importantly wash your hands often.
Ya. I know. And add this to the list of holding our breath when flushing the toilet or walking pass the smokers. And we still can't live long no matter what we tried. LOL.
I agree for an Electric tankless but the discussion was more or less comparing replacing a NG Tank for NG tankless. The NG Tankless will not consume more electricity or NG to heat the same amount of water. My tankless has a variable burner compared to the fixed burner on most tanks. The Power vent is also variable speed compared to the single fixed speed of the tank it replaced. Both combined consume less gas and electricityAV-Fishing wrote: ↑ Realistically it doesn't make much of a difference.
Tankless Water Heater ... uses electricity .... therefore your hydro electricity bills would be higher.
Standard Water Heater ... uses gas ... therefore your natural gas bills would be higher.

Are you sure you went with NPE-210A ? Cause NPE-210A has the Circualtion System and Buffer tank so the water comes way faster ...colynp wrote: ↑ I bought a Navien NPE-210A tankless hot water heater back in December 2016. I also read that CMHC study prior to that purchase. Here's the 4-1-1. (hint: the CMHC study is out to lunch)
If you are looking for more space in your basement, it's great. I love having it on the wall. I don't have to shut it off while I'm out of town (used to do that with the tank, in case it blew up).
If you love endless hot water, it's great. That being said, my 12 year old son has turned into a "shower diva" as there are no repercussions to using lots of water. Keep that in mind if you have teenagers.
You have to wait 10-20 seconds (assuming shower on 2nd floor and tankless in the basement) for the hot water to arrive. It takes longer for the hot water to arrive versus a tank. What you save on gas, you're paying in extra water/sewage costs.
If you're looking to save tons of natural gas, buy insulation for your home instead. Much better bang for your buck. Attic to R60 will save you way more nat gas than a tankless ever will.
The upfront cost of a tankless versus buying a good name tank doesn't justify the natural gas savings. You either want the space, or the endless hot water. If that's not important to you, buy a good name tank, and save your money. Use the money you saved to bump up your insulation. GreenON (if you're in Ontario) is giving you incentive to do it as well.
I figure I'm saving maybe high single digits (%) on my natural gas usage for hot water now that I'm tankless. Hope my insight helps!
Better to check and take full advantage of the extra money you paid for.. now if you have a dedicated external re circulation line comes from bath back to tank then you are set. if not you need to make the dip switch but mind it your electricity bill may go up slightly as now the system is going to keep that small buffer tank heated all the time.colynp wrote: ↑ Hello! The Navien I bought is the NPE-210A. My shower is probably the farthest distance from my tankless, which may explain the time it takes for hot water to reach our master bedroom bathroom. I did tell my plumber when he was installing it that it had the recirc feature (he didn't know), and quickly went to the manual to check it out. I assume he hit the #1 dip switch, but I haven't looked myself.
Thanks Bubuski! Would never even thought of potential health issue concerns when turning down, or off through out day, the water heater. Great article, thanks for sharing!bubuski wrote: ↑ While you are saving $ during the day by stopping your tank from igniting, your tank is not keeping the heat long enough to kill germs.

With my tankless I do not run water in my sink before a wash and have not noticed issues with the cleaning performance (HE front load washer). Like dishwashers, built-in heating elements are also getting common in HE washers since they use so little water and have longer wash times. There is need to have the filled water temperature maintained through out a warm, hot or satitize wash cycle.phantomfsoc wrote: ↑ What about doing laundry when you have a tankless system? I’ve heard there were issues with High efficiency washer and tankless systems because of the way the washer required hot water in spurts so some people had to keep athe hot water running at a sink to keep the burner running.
Is that a thing?
