will the 1500 deicer keep 275 gallons warm?

No. These deicers only warm enough to keep a hole in the ice open. This allows air exchange to keep the fish alive.

It can go to 140. The temperature rise is the key. Find out what your water supply temperature is on the coldest day and then add manufacturer specs for rise. That will give you how hot your water will be.

These have an internal thermostat which turns the heater on when the temp drops to near freezing, once it warms up enough the thermostat shuts the heater off. This should have no problem keeping 20 gallons from freezing and my water in freezing temps doesn't get above 40-50 degrees. The internal thermostat keeps from heating the water too much.

Only the deicer (along with the approx.15" attached power cord). Currently being used in a cast aluminum bird bath with no problems at all. I do place a stone on the device to keep it fully submerged in the water.

Yes. Though it all depends on your ambient room temperature. I had a 29 gal Puget Sound aquarium and was able to maintain a 55 deg temp at a 75deg room temp.

Honestly no. I don't think it would. I had a five gallon metal waterer (the one that goes with this) and over the winter there would still be ice on the top. Also this heater only lasted a couple months. I was very disappointed.

I have two pannels for 5,000 gallons, and it is not that warm, you should use around 6 pannels

No, The Warm Water Will Need To Circulate Through The Pump To Keep The Inner Lines From Freezing. You Would Have To Have The Pump On The Entire Winter With ThIs Heater

I have a 750 watt. I live in mid Michigan. I have it on a timer for 12 hours at night. It keeps a open area usually about 2 feet around the heater (pond is less than 3 feet deep there) most days. When its really cold, the circle shrinks. My fish seem to do fine: I have it near the rock pile they hang out in. You could go a higher wattage or just have it run longer. I got it in 2011 I believe so this will be its 3rd winter. good luck

I have a 225 gallon tank and I run two 150 watt one on each side and my temp. Stay. At 76

Yes, it will. We use ours at our mountain cabin which is unheated when we are not there. We go there once a month or so (it is located at 5600'). When we leave the cabin in the winter, we antifreeze the unit by running RV antifreeze through it because you cannot drain it completely and it's tubing is small enough that water freezes in it. We have not had any damage to the unit by using this method. We used to use the Coleman unit but went through 5 or 6 of those due to freezing problems. You might be better off with a Zodi. Water can be blown out of them easily but they don't work nearly as well as the Mr. Heater unit.

That doesn't sound like it is working properly but it is above freezing. Fully counterclockwise should still keep the area over 40 deg F. I have mine in a small (3' x 5' x 4') pumphouse enclosure for my well pump and filtration and it kept it well above freezing even turned all the way down as you describe. Fully clockwise (all the way up) kept it at 70 deg F or so.

Hi haven't had to use it yet , I bought it so I could use a 20 gal barbeque tank , it gets darn cold here in upstate New York , so I hope it is just a thing I will need to heat my garage when I want to get out of the house

I found the following explanation in an FAQ on the Miller Manufacturing Company (makers of the bowl) website: Q: Water freezes at 32F. Why does the deicer turn on in the 40 range and not in the mid 30s? A: As water cools it get denser and sinks to the bottom of the tank, but once the temperature drops below 40F, water actually gets lighter and remains at the surface. Thus, the surface can get colder and start freezing even though the water just a few inches below the surface is still at 40. Therefore, to make sure the deicer protects the tank, all deicers are set to turn on above 40F.

I suppose it could although I have had to defrost it once (i set the temp too cold originally) and a lot of water came out when I defrosted it.

It keeps the water from freezing. It does not get to 75 degrees in freezing weather.

Given that your use will be a bottle warmer I would suggest going to a 400 watt unit
