Factual technical comparison? - StillHope - 06-15-2010
I could really appreciate a technical comparison of a cheap (er) on demand gas water heater to a "brand name",more expensive one.
While most likely a more expensive device is made of better quality materials and probably lasts longer - general observation is not what I am hoping to hear.
I am hoping to hear from someone who actually had the experience of switching from a cheaper to the more expensive model (or the other way around) or knows the "guts"of both well enough to give a technical comparison.
By "technical" I didn't mean real scientific.
For example," because this part made of or constructed that way it makes the ignition faster or keeps water hot longer..." -something along these lines.
A have a cheaper version not by choice.I heard that all cheap ones are not working properly.
It could be the case but I would like to hear some facts if possible.
Thank you in advance.

I started with a cheaper, "no name brand" on demand propane hot water heater. Performance was spotty at best and a replacement was provided by the company, but overall performance left us still hopeful at best.While the units would fire, they did not reliably provide continuous HW. I gave up and replaced it with Takagi T-KJr. This was 5 years ago, so maybe the no names are better, but my Takagi has been awesome. Same propane and water feed, so pressure was not the issue. I did wonder if perhaps the no name was more susceptible to wind.

I wouldn't trade my Takagi Jr. for anything. Worked with out a hitch for 4 years now.

I have no direct comparison info, all my info comes from my plumber.
As I understand it the Takagi's use a circuit board for the flame control vs. a pressure sensor, so the performance is more stable and has nothing to do with the pump or pressure tank.
I just ordered a Jr. today. $640 with shipping.

Thank you,everyone.
David,about the wind - my thoughts exactly.Because the water pressure
is most likely about the same during the day,but the same day it could be shutting off constantly in the morning and working perfectly fine in the evening.
David,was the top of the cheaper one open?
I decided to give the unit some "payphone type" cover.But may be just shelter it from the sides?
Home Depot had only a very expensive Paloma (1K ),I heard JJ sells Takagi.
But for now I have to suffer and experiment with the one I have.
BTW,is Takagi made in Japan?

Hope
Yes, the top is open as it is the flue/chimney.
JJ did sell Takagi, but after pricing them, I got mine online. Even with shipping, I got 4 for the price of 3 from JJ. Yes, I needed 4.

Not sure where they are manufactured.

Thank you,David.
Just one more ?,please.
Assuming that back then were the same variety of different Palomas (cheaper than 1K) was there anything in particular about Takagi that made your choice ?

I had experience where I used to live of three different "Palomas". They all had problems and either had to be adjusted frequently or quit working altogether. They sometimes did not light if the hot water was not on full blast. I have installed 6 Takagis with no problems over the last several years. You can buy them online at plumbingsupply.com. That is where I always end up buying them.
RE: Factual technical comparison? - David M - 06-19-2010
I did do a comparison of specs, but I also met people with Paloma challenges, but no complaints about Takagi

Thank you,David and hotinhawaii.
It looks like Takagi is a very good product and doesn't depend on water pressure or weather conditions.
Does it come with it's own installation kit (I believe it was the name
HD uses for $200 separate "accessoires" for Paloma) or all those connectors are standard ?
