heater question

agreeive?fish · 01/11/2011, 12:33 PM

how many watts of heater would i need to raise aprox 100g of water about 3-4 degree F(75g dt and 30g sump volume)

i got one room's heater on the fritz and of course its the coldest day of the year and the parts on order of course

You're going to want a at least a 200w heater for that size tank.

well i just went thru my junk box(s) and located the following

2 @ 7.5 watts each (preset non adjustable,fully submergable)
3 @ 50 watts each (preset non adustable, fully submergable)
1 @ 100 watts each (preset non adjustable fully submergable)
1 @ 200 watts each (adjustable fully submergable)

now to throw them in some water to check for voltage leaks and proper operation, my current tank temp is 70 so iam not worried but is just a few degrees below where i prefer to run it so its not an emergency. and rest of the household heaters are working so the house is not getting cold just the one room is running cooler because its heater is on the blitz and warm air dosent round 90 degree corners well..lol

I am close to the same size and I use 2 x 250 with a RKL.

i normaly dont even use heaters as my mag drive pumps usually generate enough heat that my tanks stay right where i like them but this room is on the north side and the north wind is blowing hard today, and i refuse to use space heaters as they are too much of a fire danger for me with small kids/cats/dogs

I run 2x300W on a 100g. I would say use the 100 and 200. Better to have two smaller heater's always in case on sticks ON.

I would always keep heaters on a controller (e.g. Ranco) since they always break in the "on" position.

Sound advice, but I never see controllers on the must have list for newbies. Controllers and QT/Hospital tanks do not get the attention they deserve.
