"Tank temperature" refers to the measurement of how hot or cold the liquid inside a tank is.
Full definition
I logged the top and bottom
of tank temperature, ambient temperature, collector temperature, and solar radiation levels.
The points in the table assume that the solar
water tank temperature is 105F and the average absorber temperature is 110F.
The mixing valve shown in Figure 5.8 and Figure 5.9 is required for when the solar pre-heated water is too hot for delivery to the domestic taps, and when the storage
tank temperature needs to be high for space heating applications.
There are two thermostats that are hooked in series — one that senses
storage tank temperature and the other room temperature.
Your bearded dragon will need his /
her tank temperature to be no cooler than 85F and no warmer than 110F.
Different species require different optimal temperatures; with a temperature gun, you can get an accurate idea of what your pet's
tank temperature is and compare it to the recommended temperature range for the species.
One major problem I find with beginners to the reef hobby is that they frequently neglect
the tank temperature.
The collector temperature normally runs a few degrees over
the tank temperature when the pump is running.
The pump circulates water through the collectors (1) as long as the collector temperature remains at least 4F greater than
the tank temperature.
At about 3:00 pm, I took a long shower which got
the tank temperature low enough that the pump kicked back on and brought the collector temperature quickly down into the 170 F's.
The pipe coil outlet temperature appears to be within about 3F of
the tank temperature, so in about 7 minutes it has made an nearly full recovery.
Note that on the 29th and 30th, the tank reaches 140F, and the controller shuts the pump off to keep
the tank temperature from exceeding 140F.
Our tankless water heater is set to 110F, so whenever
the tank temperature is 110F or above, the tankless heater does not come on and all heat is solar.
This is to see how much the pipe coil temperature which had gone down below 100 F would come back to
tank temperature.
This is supported by the earlier tests in which a lower
tank temperature is achieved.
