Tankless Water Heaters II
Posted 25 November 2009 - 02:59 PM
I have a 3 story, 1600sq ft condo with a shower on the 2nd and 3rd floor. Less than year old LG Front load LCD Washer/Dryer and a GE SM Dishwasher I use a couple times a week. Two people.
I'm a computer guy so I am not looking to install, but I have some gift cards for Home Depot coming to me and want to use them to offset the cost. Just gotta find a decent installer.
Any thoughts or insight as to what brand or size I should be reading about? Electric.

I am still up for doing it and it depends on money and when my current tank quits (it's almost 10 years old). Sounds like I am willing it to quit.
Let me know how the other installs go and maybe we can talk on the phone sometime. Thanks

I have looked at several of these units, and though I have never serviced them, my observation is that they look to be equipped with some pretty pricey components.

Now, I sell Rinnai, I purchase it from my local supply house who has a tech training lab, a full inventory of parts on hand 35 miles away. For that price, I help keep more than a few people employed in my community, along with my guys. I generally make 1100 dollars on the job before expenses, insurance,payroll and my 30 years experience and lincesing, not to mention 40,000 dollars worth of rolling equipment,tools and inventory. After all that, I walk away as owner of the company with about 300 bucks. For that, I am now forever responsible for service after the sale. If I cant keep it running, I will replace the unitat no charge. My wholesaler takes good care of me, and I take good care of my customers.
Go ahead, buy that tankless at lowes mart, or whatever, you contribute nothing to your local economy, and deserve what you get when, not if problems erupt. Pretty soon well all be working at home depot and selling life insurance to each other. Only in America!

I own, with a partner, a computer business and we are a Union company that assembles desktops and laptops here in the US and our suppliers are in NJ and Mass. All our support and installation are done here also. We develop websites and software specific to the Unions from employees in KS, CA and WA.
Not promoting Union as much as "Keep it in America". Sure, computer components are tough to get "US made" but we do what we can to keep what we do here and we do put food on the table for many US workers considering our small size.
Hopefully I didn't miss your point and thanks for the input.

What are the advantages of the Rinnai product vs. the Big box units?
Now, I sell Rinnai
Also, are they any special issues using propane? I'm currently using a 2 year old 100 gal electric. Got 6 people, 4 teenagers, in the house.

I've had two fail in three years. Cost me $50 each time.
I love it. I have three teenagers who like to take 30 minute showers. I probably don't save any money, but the endless hot water is worth it to me.
I installed them myself. (Except for the wiring. I'm a chicksh*t when it comes to wiring. I called in a professional.)

The value proposition for tankless is very good; however, I have found one issue I've not been able to find a solution for use with High Efficiency (He) clothes washers. I've heard of similar issues with dishwashers, but I've not directly had any issues myself with Tankless and dishwashers.
1) Most of not all tankless manufacturer presents their flowrate information on the tankless as how many gallons per minute (GPM) their units can produce based on temperature rise (how much the unit has to heat the water up by).
2) The High Efficiency washer I'm looking at cares about water PSI, rather than flow-rate. My tankless unit outputs 3-3.5 gpm at the tank (~90 degrees rise) but by the time it gets to the laundry outlet, it drops to 2.5 gpm. This is acceptable flowrate for baths and kitchen use, but the washer errors out.
The tankless is installed (i.e. sunk cost) so it's not worth going back to tank heater.
Any options for the washer?
I spoke with Noritz yesterday. They said one option is to install two tankless in parallel (not in series as it would increase wear and tear on the device). The down side is you can only install tankless in series if you have horizontal wall space or enough clearance for the venting; which I do not have. Also, the cost to install two tankless would negate the very reason I went with a tankless - cost savings!
One thought I had was to turn down the temperature setting (less temperature rise = higher gpm output). However, my control settings only allowed me to bring the temperature down to 100 degrees F. That didn't work.
I"m trying one more option before I go with a traditional, dedicated tank just for the washer. I"m going to change out the 1/2 inch copper lines to the laundry faucet to 3/4 inch to give it more volume delivery. I"m hoping that will do the trick. I doubt it will because the NOritz can only output 3 gpm so even if I increase the piping between the heater output to the laundry faucet, it may not help much. I fear I will need to run a separate, dedicated tank heater for the laundry.

The first one I installed was a Bosch AquaStar 125BO NG outdoor model and it has been an awful product. The problem is that he pilot would not stay lit. Many calls to Bosch, with try this service bulletin then then this bulletin then have cleaning the pilot sensor every 2 months. My mother-in-law just gave up and had a Noritz installed.
We own an AquaStar 250 NG model and it in the wintertime kept erroring and would have to be reset again very poor help from Bosch.
I will NEVER buy or recommend a Bosch tankless hot water heater again as long I am still making journeys around the sun.
