Is my idea crazy or should I pursue it further? (EV as sole house battery)

If they can extract enough heat from the sea water of the north Atlantic to heat Iona abbey, you'd be laughing.

We have a bit of a pond out the front, the Murray River, but that's a long way to run the pipes

I bet that is a good temperature all year round. Pipes would need to be well-insulated as well, though. Otherwise you'll end up with the same temperatures as an air-source!

but we could always put a few coils in the rain water tank, it'd take a while to heat up 10,000 ltrs, but I'm not sure how much heating it would provide in winter ..... although it only drops to 0* for a few hrs in the morning maybe 3 days a yr ..... so it would probably store enough heat for that ......
Thanks for the idea, certainly worth a try ......

Interesting!

No chance you'd boil it then?

Now that's a thought, a much smaller tank and use it to kill any bad stuff in the river water we pump up to flush the toilet and use in the shower if the rain tank gets low ..... or even circulate the rain water through the heating tank ..... one of those solar water heater heat exchange tanks, the heated water circulates in the bottom 1/3rd and the heated water is in the top 2/3rds ...... so many possibilities for adaption .........

You are a smart cookie, why do you let your mum dress you like that

If you're going to use a water mass it would have to be quite large or be running water.. a small pond is ideal if you want your own skating rink

.. or curling rink. Now there's an idea!

I thought a heated wand thing was used for that .... not really my thing though

Extracting heat from the water over this side of the globe isn't really the issue, it's getting rid of the heat from the refrigerant that is the issue.
The water from the rain tank could be circulated through the top of the heat exchanger tank to provide more warm water to chill and the cold still returned from the bottom of the tank ....
