Lonnie, Do you have your aquaculture Certification/permit whatever for the Blue Tilapia yet?  Though I'm really not a big supporter of growing tilapia I still get people who ask me where they can get them and I could send them to you if you are legal.

I read the rest of the thread, after my last post.  John Parr where are you located?  Alaska?  $1,200 electric bill, WOW!  I lived in PA, for 35 years in 2,100 sq.ft. all electric house, on a budget plan bill would run about $250 a month. Be sure to insulate the TOP of your tanks. I would look to enclose the tanks in an insulated shed.  Then give thought  to possibly  constructing another outer shed..

You can plug mutiple heaters into the same timer. Problem maybe circut load. 15 amp circut will max out at about 1,800 watts.   I intend to have a 30 amp sub pannel installed after Christmas as long term I am adding 5  250 gallon tanks and 20 more 4 x 8 grow troughs with 3 sump pumps.

Yes a couple of 1500 watt or 2,000 watt water heating elements running 24/7 can get costly real fast.  Once the water temp gets into the mid 80s. My smaller heaters combined with the R-13 insulation should retain the heat and maintain the temp.  Thanks Norm. I think useing these on a timer may work well.

You need to make sure the heating element is completely submerged in water, otherwise gets too hot and pvc will melt. I just constructed a heater with 2000 w element working great. but I don't want an extremely high electric bill.

Hey everything works fine in theory, but then omest the unplaned. The heat from the hot water element melted the PVC threads it was connected to. I covered the electrical wire contacts with the "rubber like" marine caulking.  The intent, as I do not have a thermostat on it, was to plug it into a timer.  I start my sump pump and open my valves and feed my fish at about 10:00 AM daily.  I usually spend a couple hours on "chores" such as cleaning filters.  Today I drilled one of my 250 gallon tank for a drain valve and installed the bulkhead fitting  & drain valve and interanal "filter" on the drain.

I am in Hudson, FL. 30 miles north of Clearwater and 3 miles from the Gulf of Mexico. We get about 10 days a year, when night time temp. falls below 32 degrees for 4 to 6 hours.  I now have 4 outside tanks in operation.  I have insulated them with R-13 fiber glass building insulation by tieing it with carpenters twine to the outside of the tank .  Tank heaters get a little pricey  at $34 for 200 watt and $37 for the 400 watt. The 400 watt does a good job on my 100 gallon tank, but can't seem to get temp. over 76 degrees on my 250 gallon tanks and more like 72 on my 330 gallon tank.

I am worried about my electric bill. I am thinking I need to move everything into the greenhouse. I will let you know if it is outrageous. Thank you

PG&E must love you, Dave. I also have about 5kw of heaters, and my elec bill last month was $1200. I am switching over to wood heat, hope I get operational before I go bankrupt.
