There must be an electric option out there that would work?
You may need some serious power packs to last long enough, but there are plenty of options on that front.
Do small electric fan heaters really need such huge amounts of power that its forever a complete non starter?

The short answer is yes, they are a non starter. Electric heaters require more power than you could supply from a sensibly sized battery.

Even the Lithium Ion ones that have replaced the old lead leisure batteries?

Yes. I did some research regarding electric cool boxes and using batteries. It was a non starter.
Assuming you are using a 12v device running on 12v DC current from a leisure battery of some sort you will need a heavy lift helicopter for the batteries needed to run a heater for even 24 hours..
In round figures the 12v cool box I wanted run was a 50 watt unit. Divide Watts by volts to get the ampage = 4.8 amps.
To run the cool box for 1 hour will require 4.8 ah(amp hours)
So for 24 hours you will need a 100ah battery. Remember this is for a 50watt device
The wattage of current small portable bivvy/camping heaters seems to go from 800/1200 watts. I don't know how much a 1600 ah battery weighs or how much it would cost. I think way too much is the answer.
Just checked. 300ah battery. £1500 at 35kilos and you would need 5 for 24 hours. Couldn't find a li/ion battery with anywhere near that capacity. Sure the price would be horrendous.

Not sure why everyone's ignored my Gasmate Heater post? Its not like I'm waffling or anything . . . .
7-8hr Battery for the hot air / heat exchange mech
Screw in Gas Canister (standard sizes)
Sits OUTSIDE bivvy and vents warm air in
Safety cut offs
Looks pretty safe to me! Can you get them over here?

I bought 1 for last Winter, at my age (70) blood has really thinned out and feel the cold more than I used to. Only used it twice for a couple of hours at night, wouldn't dream of leaving it on while I was asleep and it was of no use in the morning, gas cylinders too cold to work! Of course I could have put the gas cylinders in the sleeping bag. Off again this weekend for a week or so, bivvy heater staying at home as is the Mrs, so nothing to keep me warm.

Sorry, not ignoring your suggestion, just answering the battery powered electric heater question.
Can't find a supplier over here. Looks a lot safer than many and would definitely heat a bivvy but expensive to buy and expensive to run. 5/7hours per gas bottle and 7 hours battery life from the built in battery that takes 5 hours to charge. Also pretty big and heavy. Not sure how practical it would be on most GB lakes.

Thanks for the electric heater info, defo a non starter then! :-(
Another option maybe is heated clothing?
Dewalt and Milwaukee have been making heated jackets/gilets/hoodys etc for tradesman for a while.
They are quite pricey when you add a couple of batteries but if you really feel the cold worth looking at.
With Avids heated sleeping bag just coming out its only a matter of time before we see similar heated clothing aimed at the carp angling market.

Chap I buy my bait from (Hallum Baits P1 - excellent bait by the way) has a similar set up and fished many a winter at Elstow this way . . .2x 17l buckets of coal did the job for a 48-72hrs session . . . .madness but warm and safe(ish)!
Think the Polish lads have been fishing this way for decades . . .!

P1 Is an awsome bait! Pete is a top bloke too !

A bit late to the party on this one but if you need a heater without the dangers have a look at diesel heaters on eBay.
These come in a metal case with a tank for the diesel.
They come with a pipe which can be run into the Bivvy and the heater left outside.
A mate of mine where my boat is moored has one on his boat.
They throw out a fair bit of heat and they are quite compact.
I will try and get down there this weekend and get some pictures of your interested.
Hope that helps.
