2 yrs ago i was so happy to switch from trad to wfp, to get away from wet  cold hands in winter. To get away from hands freezing on ladders etc etc to wear gloves and just simply use a pole, what a relief.

Yet these last couple of days with frosty starts, had enough of the cold and not excited of prospect of cutting into my tank or carrying gas. So since my 500ltr wydale tank is effectively split into 2 250ltrs, im sticking a 300watt tropical tank heaters in either side over night. Should reach over 30 degrees and since my tank is insulated it will hold temp for day......happy days
 
Plus my local supplier did deal. £28 each but as i needed 2, sold both for £40. Even happier at that

Nice, so how does it work you just drop these into tank at night connected to mains, then it heats water up ready for the morning?  does it cost much to run something like this you think?

Might do this myself, seems like a good idea and fairly easy, my tank isn't insulated though, how long you think water would stay atleast warm for during the day?  If i could get 4 hours i would be happy

Bargain.

Would running 2 of those overnight make much difference water temp wise though on a 500 ltr tank?

Probably. I doubt it would boil it but a few degrees is all you need.

Its a wydale tank, the water is segmented into two halves so effectively im heating 2 250 litres. These heaters will easily get the water to 30degrees which is better than cold for my liking as im doining maintenance cleans every 4wks. Plus the tank is insulated so the temp should hold.

Cant see them being expensive to run during the night at slightly cheaper electric costs. Ones who keep fish have these things running 24/7 all be it they are thermostated so not constantly running, but if i have them on from 10pm till 7/8am next morning it should easily do the trick.

Only down side is soupys post

Will do next time, esp with them being that cheap. I thought they may be a fraction cheaper on net, but thought for convienience of popping into local supplier as i passed would warrant any small saving from internet..........obviously i was wrong

Funny you mention gas water heaters as I've found another great advantage using an lpg water heater when doing exterior cleans. That is if I don't need to use hot pure from the van tanks but still want to use hot water. All I do is just hook it up to an outside tap instead so have an endless supply of hot water on demand.

I don't mind paying over the odds locally if I need to get stuff in a hurry. Mind I bet if you go back and show them that link they still will not match that fleebay price.

Not sure if this link will work or not but going by the figures it takes one hour for a
3.5kw heater to heat 100lts of water by 30degrees, you have roughly a
sixth of that so your talking around 5 or 6 hours per 100lts.
Doesn't look as if your heaters are up to the job.

I guess i will find out tomorrow morning, but running from 10pm till 7 or 8 am gives 9 or 10 hrs to heat. Each heater is effectively heating 250ltrs each so will see n postbhow i get on tomorrow. But either way it isnt going to cold n freezing in hose.

From your link SeanK.



1 degree per hour. Not too bad...

[Soupy]

10 1/2 hours:



11 degrees...

"Re: finally on hot water" I don't recall 11c being hot water   more like tepid 
For your 40 squid you would have been better of putting it towards cutting a hole in yer tank and fitting an immersion element for frost protection.  Or put it towards a chepo hot water on demand lpg heater instead.

I'm also not convinced that the radiant heat from trying to warm the tank with those fish tank heaters would be enough to stop the other kit in the van from getting frozen.

[nathankaye]

Well, heres to finding out. Start temp in tank is 5.8, so i will let you know in over ten hrs what it gets to.
Its worth a shot anyways and i know where to buy them at 8 quid if i need to throw another one 

[Smurf]

Let us know how you get on

It takes my 3000w element 6 hours to heat my 500ltr wydale. My prediction is you will get luke warm at best.

I suppose so many elements come into play. For instance the volume of water, is it vertical or an horizontal tank. How long is the elementand what water flow to circulate the heat. For instance a 12 0r 14 inch 3000w element compared to a 20 inch 3000w element etc. Also is the tank insulated or not etc etc.
I have the option of leaving turning the heater on at 9 pm or before if needs be to give extra time if needs be and simply run an extension cable to van rather then being overly concerned with the wattage and artic wires or changing the electrics for a 3k element. All the stuff i want to avoid in order to keep it simple.
But i wil post the results all the same.
