I seem to have missed a previous thread on this subject:

No shock that there are other skeptical members here...
MMT,
I have been somewhat following your projects on the forum. So far, it seems you have multiple systems in the works:
1. High seer (AC only) air-source unit w/ desuperheater
2. Water thermal store
3. Evacuated tube collector
4. Hacked ground source heat pump
5. Hydronic under-floor heating
6. Under-slab heat injection field
However, I'm having trouble figuring out some details:
A. what runs to what
B. how do you control it all
C. what army built it
What awesome potential this list has! I'm riveting my seat to this thread. I wish you the best of success in composing this literal symphony of engineering.
