I can't think of a good reason why you would do that.
How much do you expect to raise the water in your tank by? How long will it take? What do you expect to achieve doing this?

I was thinking about re circulating hot water through the reel and back into the tank to warm my 650 ltr tank before work ... I have the cor woods non 20 minute cut out heater and I was just wondering if any of you guys recirculate your water at all before leaving work ?

why not buy a hot water system and stop being tight . We hate it when custys penny pinch but think nothing of doing it ourselves . You have to speculate to accumulate 😇
I haven't a clue what Julian is on about tbh.
If the OP has a gas heater, surely the best and most economical way of heating water is as he is using it - on demand. That's what nearly all hot water users do.
If the OP has a full 650 liter tank, it will take a 5 lpm pump 130minutes to turn the water over once, that's over 2 hours. Now he is pushing that water through his hose reel. That will reduce the output of his pump as most of us use either minibore or microbore hose.
How much energy will he take out of his battery doing this? Running flat out, our Shurflo pump uses just over 2 amps pushing water through a 3 meter length of 1/2" hose. Restrict that and the amperage drawn by the pump increases.
Lets go on; we have run our pump for 2 hours and raised the water temperature in the tank by say 20 degrees - the water in the tank would be around 30 degrees. Hot water rises to the top in a tank, so whilst the water at the top is warm, the water at the bottom where the outlet is is cooler - heat rises.
So during the day the OP will be taking colder water from the bottom whilst the water at the top is warmer. During a cold day most of this heat will be lost.
Another question is; how much gas will his heater draw everyday doing this?

I have no idea what or who that comment is directed to.
If it's me then I already have a 2 man fully operational Heatwave Thermo 2 diesel heater in my garage that I'm in the process of modifying (when I find the energy and motivation to continue with it.)
I also have a test bench 5kw diesel heater that I tested a couple of years ago and found it totally inadequate to do the job. If I could attach a photo of it I would.
I recon I have about £1250 invested into this test bench alone; 2 Webasto Thermo Top C heaters, wiring loom, digital controller and numerous water to water plate heat exchangers.
