Nope, a lot of these guys are resistant to "foolish pursuits"..
Like when I connected the heating elements of my hot water tank directly to solar PV panels.
Most people think it's a waste to use PV to heat up water.. Not efficient. At all.
But, it does work. Pretty well in fact.

Temperature control, turned into a problem, since the tank tends to over heat when solar is too good..
The other day, it was super cold here, and the sun came out.. My hot water
tank zoomed up over 170F.. I had to cool it down..
Normally there's no problem, but PV works much better in extreme cold..
In the summer, I just disconnect one of the arrays for a few months.

The whole house efficiency idea is what I was looking at when I ordered
a 24k BTUh mini-split ASHP. It worked!
But the den (addition) on the back of the house has so much glass, we installed a second mini-split for the den..

After seeing how both of Sanyos work together, I'm starting to think a house
with a 3 or 4 heating zones, could be handled by 3 or 4 mini-split units..
Because, the smaller BTUh units use less power/per BUTh and can work at lower temperatures..
Right now, one of my Sanyos is down. Needs repair.
But, the other Sanyo is doing a pretty good job doing the whole house..
(The den is still a little cool).

So, what happens when it's 97F or 9.7F and your Whole house system goes down?
If you had bunch of small 9k to 12k BTUh 20-30 SEER units, one of them going off-line won't be a big deal..

27 SEER / 14.5 EER / 9.0 HSPF Thems some good specs!
