I was watching another post last week on heated van systems , someone was thinking about putting a small submersive fish tank heater in one of his tanks ,I think a 250 ltr tank .Knowing full well itll not heat it up to the point of getting hot water but enough to take the chill off the water and not ice up over the coming winter . it got pointed out to him that itll be no point the tanks to large blah blah so on. I thought to myself I don't have a van system but I use 20 ltr barrels I wonder if I could do it ?? the idea being drop it in one barrel while going to a job then move it to the next barrel while I'm using the heated barrel . and so on all day . obviously there'll be a bit of DIY in involved i.e. hooking it up to the battery(the one on the trolley ) and maybe I was thinking somehow fixing it to the lid of the barrel for easy putting it in and taking out .that way if it fixed to the lid when screwed on itll not touch the sides . has any one thought about or done something similar . its just an idea at the mo but is it worth looking into ,I'm I on to a winner or just a waste of time? iv been trad for 14 years and wfp for over 18 months last winter wasn't bad at all but thinking this winter might be snowy icey cold af . when iv trad in the morning winter months the waters always froze on the glass or parts of the glass ,how badly does this happen when using wfp ?and does it really matter if you use hot or cold water in freezing weather . yes iv finished today and instead of cleaning the kitchen iv decided to come up with something that may or may not help over winter . just thoughts and ramblings would it / could it work ???
