Prefered Tankless Water Heater

rhinoguy

I need a tankless water heater for MY house. Two people, five rooms, one bath, washer, dishwasher. What have you guys installed and what gives the least trouble. I plan to use gas, the chimney is brand new. Bosch? I also have an attic heat preheater so the heater should be adjustable downward to prevent scalding. The old 240 volt line is sitting there if I use electric ignition. I can split it for 120 volts. My house has copper everything, including drains.
Thanks guys!

After reading two dozen owner reviews it sounds like they are annoying to operate. There is a much longer wait for hot water, then you must leave the water running to maintain heat. That's wasteful of water, which is a problem in my too big, riverless city. So who makes a nice high efficiency gas tank type heater? I have electric there for electric ignition. I like reliability over price. Labor is expensive, even mine!

well since you have made up your mind I won't bother to explain why a tankless is so much better than a tanked...because you read some moron's reviews...I mean a home owners reviews. They were probably reviewing the Bosch unit.

Good luck with that tanked heater

I'd like to hear.

I was going to ask what you thought of this tank brand, but I suspect I'll just get insulted.

Who was insulting? I wasn't insulting you.
Your comment was like, "I was gonna go buy a new Ford truck, but some stanger said he didn't like his, so now I'm gonna go buy a Honda Accord"

Look, there are MANY varibables which dictate how a tankless performs.
My opinion, Noritz units are the absolute very best, no 2 ways about it. I have installed about 100 of them, and have NEVER had anything go wrong on them. Again, IMO Bosch is the bottom of the barral. Rheem just had a massive recall because they are not built very well. Takagi's I got nothing bad to say about them. Paloma.....Home Depot special...no thanks.
Look, #1 reason tankless units don't work very well is because they are undersized with gas. People/plumbers do this every single day. When the unit doesn't have the PROPER gassing it wants, it doesn't work like it's sopposed to. To temp times go up....they can become unstable as far as temperture. Last week I had to completly reinstall one that some hack did. Him and his half inch gas line. I actually got a thankyou card from my client that Noritz factory sent to me.

My tankless runs perfect, why? because it's installed correctly. Like I tell other plumbers I have trained...You have to give the unit exactly what it wants, when you do that, it will perform.

In my home where the tanked heater was located it took about 5-8 seconds to get hot water. Where the tankless is now, which is about twice as far away takes about 8-12 seconds to get water to temp....and it never runs out, and my gas bill went down about $15-20 per month. ANd I have more storage room with the tanked out.

Search this site, believe nothing you hear and half of what you read

I have put a few pics of some I have done over the past year or so...

Where Can I find info on the Rheem Recall??? I just installed a new Rheem furnace and tankless water heater....BOTH blower/fan motors went bad after 3 days....I had them replace the whole tankless unit after I swaped a board with an obvious, fried SCR.....Now I am hunting down a leak which I assumed was in the hard piped lineset, but its looking more and more like it might be in their coil.....VERY UNHAPPY WITH RHEEM

On a positive note..My new washer says "When used with a tankless nat. gas water heater. it will cost only $16/year to operate"...Ill never know for sure but its a nice thought.

I don't think the recall was about your problem, but they are now on my list of crappy tankless heaters.
