I have a 1000w titantnium pond heater on a thermostat in a 2000l tank and from last years experience I noticed that the water was taking ages to click 'off' the thermostat....until..............I ran the tank pump back into it self and then the thermostat showed 16 deg and I only set it to come on at 5 deg....

So now have set a timer on the pump to circulate the tank water for 15 minutes every 2 hours for the 1st 48 hours and then 10 minutes every 4 hours for the rest of the week.

Cheers
Dave.




what type of pump do you use dave ,  I have a 1 kw heater which i intend on dropping in my 400 ltr tank overnight  in pickup , but it would be give even heat distribution with pump would'nt it . 

Will it  be safe enough to run extension straight out to pickup in freezing temps , I intended on covering tank with a couple of duvets but do i need to keep them from covering heater or can i put the whole of the heater in to the water .     MIKE

If the heater is hung low into the water, then as heat rises the water will circulate naturally.
I drilled a small hole in the top of my tank, passed the cable back up through it, lowered the aquarium heater down til it was 2" from the bottom then fixed it so it wouldn't drop lower (don't want it touch the sides either ) and it worked fine.
Didn't make it warm, 600watt is not enough power for that, but kept it from freezing.

Looking at instructions with heater it says a pump will circulate the heat evenly . But looking just to drop something in to tank to create some kind of flow or movement in water in order to try and get all the water at the same temp.


Thanks sparklebright heater came with the suction caps and outer protector in order to fix to side of tank always best to check before total submersion , dont want to make any mistakes ,  

I think this is the best option as i have limited space in back of pickup as i have a solid tonneau type  cover on back of pickup with about 5" of room above tank  so hopefully this will work safely with this type of heater .  

which can be seen via web link to  photobucket  below my profile name  if you click on image with cover it will enlarge .   MIKE

silly question maybe but freezing weather doesnt affect the power cable does it?

mine was out in -11 last winter. 30 meters of it, no problems

i fitted a 11" immersion heater last winter

before i buy one, just thinking would an aquarium heater not melt a plastic tank if suction cupped to the side?

what capacity is your tank mate?, and did you not want to let it touch the side of the tank because it would melt the tank?

It won't melt the tank,.. the water takes the heat away too fast for that to even start to happen.

oh right yeah, that makes sense now you mention it!

thanks mate

anyone else had any problems with burning or melting plastic tanks from aquarium heaters?

[Mike #1]

it wont melt the tank mate i am going to put a 1 kw heater in mine plus i am going to cover it with 2 cheap double winter duvets , 

I am going to build a frame around my static tank and insulate that with loft insulation and cover with a waterproof cover ,

I think its important to keep water in static tank at a reasonable temp otherwise it will hard work for heater to get water in van mount tank to a reasonable temp,
