Can you leave an aquarium heater running while you're out working via a power invertor?

no, the power drain will kill a large battery

Hot water freezes quicker than cold water?  

I've seen quite a few posts saying this but surely that can't be true?

If you put water on the floor at say 50deg it will loose its heat quicker than water at 8deg. But, say the warm water cools down to 2deg in 5mins and the 8deg water cools to 2deg in the same time, are you seriously saying that the water that started off warmer is going to continue cooling at a faster rate and, in effect, overtake the other cool water in its fall to freezing point???!!!

The logic and Physics in this process seems quite simple to me or am I missing something?

these aquarium heaters OK to be left on through the night?
just been out and checked the temp of the water by touch and can feel the difference to this morning.

Hi all,
Just thought I'd let you all know how I got on the Aqarium Heater in my tank last night,
I checked it last night b 4 going skittles at about 6.30 pm, the water still cold,
 then at 11 30 pm when i got back and the water was better than b 4 but not brill.

I have been out and checked it this morning about 09.15 and it is warm ish.

The hearter is a 300w and has been on since 3 pm yesterday, the tank is 250ltr flat.

I still cant go to work today as like alot of you, I got up to see 6 /8  inch of snow 

Have a good day in the snow guys

Steve.

results of my two 300watt aquarium heaters in my 400lt tank.
OK water this morning was 17degrees which meant i went to work.
so for an outlay of 40 quid thats great!

today i will only put 300lts in the tank and hope for round about 25degrees.
i have rescheduled work for the rest of the week (half days really) and will be chuffed to do that.

conclusion......40 quid spent ......£400 of work done would be a great result.
                                 regards suds.

i am picking up 2x300w tommorrow for my 400l tank, this week ive been using hot water from the tap through my di to backpack and sticking containers next to radiator in the hall, it brings them up to a nice 24/28 degress and at lunch time i am still getting a healthy 10 degrees at the brush. bit hard going trying not to fall but it works

I am been looking at pool heaters

http://www.aspectspools.co.uk/elecro-evolution-stainless-steel-electric-pool-heater

So for those that have have IBC's and a van tank do you think that in these time of very cold temps...perhaps it is possible to link the ibc storage tank and the van tank a then pump the heated water around the complete system.

Just a thought...this way the whole system could be heated and kept warm and ice free for the whole night and I would imagine the van would also get a little warmer..so nice to get into in the morning.

Perhaps you could fit an old radiator into the back of the van and that would then also keep the van warm.


Cheers
Dave.

Does anyone know if its possible to run an aquarium heater of 12v?
I have an inverter but fear this will drain my vehicle battery but was wondering if it was possible in some way to hard wire directly to the pump battery.
I figured the drop in voltage may not be enough to run it but am hoping I am wrong. perhaps it might be enough to just keep it warm therefore stop the tanks cooling so quickly.
