I have a quick question - a few of you on this list have the Sanyo or other Mini-split. I am almost finalized on my thought to install a quad mini-split on my second floor, which will give me heating and cooling while I work on the DIY....

What I would like to know is, can you tell if the outside unit would lend itself to conversion to Ground source?

In other words, is it suited for a hacking by adding
chilled water piping, or clipping on additional cooling
fins that could then be connected to a ground loop?

It seems silly to have 2 systems, but my idea is to
leverage the mass market volume pricing of an ASHP,
and with it the "sealed" system.

My understanding is, using stock pipe lengths
does not require special tools (does it?).
And it is much easier to plumb in a 3" cable
than a 4x10 duct.

Thanks
Seth
