Advice - Tankless Water Heaters !
I finally decided to replace the water heater I have with a tankless one. After some research, I narrowed the choices down to two "finalists": Takagi and Rinnai tankless water heaters. Rinnai seems to have some advantages, among them higher output (8.3gpm vs. Takagi's 6.9gmp) and, most important, lower kick-off flow (0.5gpm vs. Takagi's 0.75gmp). On the other hand Takagi seems more spread than Rinnai and also I could find a lot of information for Takagi and almost none for Rinnai.
Need some advice from people who are using these water heaters.
Interesting what happens over time
its funny how you hear more and more about people
wanting the tankless units and the people
who complain about them after they own them
over time it simply has to fail
its just a matter of when. and how soon......
just like the last thread where the 2 year old Takagi went down and
the home owner jury rigged up his own repairs for it.....
going green is a fad that should not spread to things as complicated and
expensive as these are
I just had a homeowner
today calling about the tankless units at about 12.30,
but before I could get back to him -- having a Friday power lunch---
he had gone to LOWES and now is
hell-bent hooked on a Bosch....
took the bait ....hook, line and sinker......
I wont be able to talk him out of it no matter what I try to tell him....
Hell, I just do this for a living,,
the guy at LOWES is the expert.
my Green tankless water heater
When they can get the price down to about
the cost of what a normal water heater costs
then I will get one even though the install costs
will still be higher...
then you might break even in 10 years or so
I am still haggleing with supply houses for a
decent deal on a tankless heater right now
to keep going with my own little experiment
here is a pic of my "green tankless heater"
the unit was installed in 1910 ..the reason
the tank type heaters took over in the 20s and 30 was the fact that
these were too complicated and too much touble even back then
and people were constantly blowing them up..
they thought that they had made a giant leap forward
when the first tank type heaters came out with
the internal thermostats...getting away from all these
high pressure issues and valves that had to be manually
controlled to get hot water..
I believe that this was called a "side arm" heater..
it can get hotter than hell
do you have a system with some sort
of antifreeze in it that will not boil???
if you are useing a water type drain down system
those puppies can literally boil the water in no time...
if the recirulaitoin pump were to fail
On our summer vacatioin in florida last summer it was 98 degrees at disney land for the whole week....
(it made the battan death march look like childs play)
really all you need to do in Florida is put about 2500 feet of
3/4 wirsbo pex in your attic feeding your hot water heater
and I can guarantee that you would probably never run out of hot water.....
