Weirdly, my dog does this. The first time I planted potatoes I hadn’t checked them yet and one night my dog came back from going outside and dropped a potato in my lap. The next day he did it again and I went out to the garden and found two holes where he’d been digging them up.

If you’re in the U.S. you may even be able to get a free (or at a substantial discount) commercial heat exchanger later this year: https://www.hvac.com/resources/inflation-reduction-act-heat-pump-rebates/ Not quite as fun as the DIY version though!
