Mine does the double duty thing but you have to switch it over manually.
Push one button to put it in heating mode. Another button puts it into
chilling mode. Nothing automatic there. Is the Azoo different?

I wish I had purchased one of those electronic chillers long before I
finally did. A lot of light and a few pumps really add up. About 2
months ago I went to one pump and ran everything off it like Tom
suggested above. Mostly I was just trying to get everything out of the
tank and out of sight. At the same time I got an AquaMedic chiller.
When I got it I discovered it's a German product made in China. I
haven't looked into the other brands but it's not quite as small as the
Fritz Teclima model though the power supply is internal. The fan is not
too loud but it is not all that quiet either. When I have some time I
plan to look into replacing the fan with a really silent one, something
like the IceCap fans. The only other thing I am not real thrilled about
are the fittings. They are a hard plastic and did not seal as well as
the Eheim stuff on the filter. I had a little leak that was difficult
to stop at first (it dripped but not enough that evaporation wouldn't
take care of it) but after some effort it is now water tight and I have
had no other problems. It works like a charm.
Regarding the noise level, it really is not that loud but I guess I have
just been spoiled by my Eheim 2026 filter. It's so quiet I occasionally
look at it to be sure it is still running. Even with my ear down by it
I cannot hear it. No kidding, I have to check the flow indicator to be
sure it hasn't stopped. You'd think after a while I would learn but not

Actually my chiller more than handles the load but you are right, you
should check for the tank capacity and desired temperature drop when
sizing one for a tank. The two I looked at (AquaMedic and Teclima) were
more than capable of handling my tank as I only needed about a 2-3 ºC
drop. Just be aware of dueling temperature controllers. The heater is
set for 24.8 ºC and the chiller at 25 ºC. This keeps the tank between
24.3 and 25.1 ºC - the heater's hysteresis is .1 ºC but the chiller is
closer to 1 ºC.
