overpower better than underpower.

It is best to purchase a one step higher model than the one you may need. Reason being, when the hot months are upon us, your extra capacity chiller would be able to cope easily than a lower capacity chiller. Another important thing to note of is to modify your chiller to use an external temperature probe and place this probe in the sump, preferably the 1st compartment if it is possible. This external temperature probe modification is to ensure that the chiller is monitoring the real time temperature data of your tank temperature instead of the chiller water compartment in the chiller itself. The chiller has a flaw in the design and will have irregular kick in and out timing because of the pump flowrate.

With the modification, chiller owner are not penalised with their choice of pump they used. Even a low flowrate will ensure that the tank reaches the desired temperature setting in a short time and ensure that the kick out time would be longer compared to the kick in time of the modified chiller. Shorter kick in time and longer kick out time would help in the lower cost of electricity consumption that has been on the rise every quarter.

Hope this helps!

how to modify chiller to use an external temperature probe?

[kenny1111]

by the way, if i get a 1/2 HP chiller will it be overkill for my tank? higher bill money?

You can consider the Teco I am selling. Maintenance free (when I call up a supplier to service for me) and comes with a cabinet (customized).

The copper coted coil will cause a problem in marine tank? thought will lead some metal out into the water?

For yr tank, 1/5 or 1/4 is more than enough. For drop - in, personally I feel wise for 4 ft and above unless u don't want the heat fr standalone chiller. Super overpower is definitely overkill. For ext. Thermostat, u need the controller with probe and hook to power socket. Yr chiller is supposed to set temperature low or lowest to ensure the ext thermostat once reached the required temp, will get activate power supply to yr chiller to kick start and run. One ideal temp reached, it will cut off power supply to yr chiller. For artica, may not require but for other brands, good to have as their internal thermostatt usually turned faulty. For drop in could, ###### seems safe but any leakage is likely to kill all yr livestock. Copper coil with rubber insulation, danger is rubber turns brittle after something and exposing the copper to rust thus leak. Best is a drop in in isolated area.

Thanks for the detail explantion. understand.

So where can i find the Ext thermostat with controller and probe? Anyone can fix it on? dont want to get kill for anyhow joining the wire.

Look for bro orsony. Good luck.
