Do not, I repeat, DO NOT! get a SETS brand tankless heater.
My husband and I purchased one about 2 years ago, against the advice of
our plumber, who actually refused to install it. Yes, it has a
lifetime guarantee, but we have had nothing but trouble.
First of all, we paid another plumber/electrician about $700 to install
Then we couldn't get it to run hot water. You would turn on the water
and it would heat up for a few seconds, and then internal breakers
would trip and turn it off. We called SETS and they sent new parts.
That didn't work. So they send a new circuit board. That didn't work.
Then instead of replacing the existing type parts, they sent ones
without breakers in them to circumvent any tripping. Mind you, all
this takes time, and the mail from Florida to Virginia takes a few
The next thing that happened was that the internal washers went bad and
we came home to water all over the place. Again we called. We waited
a week and called again. The original order never did reach us, so
they send washers again.
Now the latest, this morning at 5 am, January 26, my husband went in to
take a shower, 20 degrees outside and we have no hot water.
In addition to this, through the two years we have had the heater -
yes it does go on unlimited hot water which is the only good thing
about it - but - the drill for running a bath or shower goes something
1. Turn on the water to all hot.
2. Let the water run full blast for 30 seconds to two minutes.
3. At this point you will feel the water get warm, and then VERY VERY
HOT - hot enough to scald you.
4. Then it gets cold again.
5. Then after about another minute or two it will warm to the
temperature it is supposed to be so that you can take your shower, wash
your face or whatever.
We were willing to put up with the fluctuations in order to get
unlimited hot water, but we have had it with SETS.
We are in the process of building a new house and WILL NOT be
purchasing a SETS. We are now looking at Bosch, which I understand is
a much better unit.
My husband emailed to SETS this morning and has not heard back yet,
even though he left two phone numbers. And he did tell them that I
would be posting our dissatisfaction on the internet.
Thank you for your time.
