Default ASHP is the new GSHP

The basement isn't heated. We use 2 Sanyos to heat (and cool) upstairs.

The A7 will dehumidify and cool the basement during the summer months without using much power.
But during the colder parts of the winter, when the basement temperature drops,
it's going to take more power to heat the water.

A GSHP would be nice, but digging a deep ditch in the backyard is pretty much impossible.
I might be able to do it someday when they invent a cheap Laser excavator that can cut soild granite.


I have two ideas that might help out with winter power usage.
I may use one or both of these ideas.

1. Vent warm attic air down to the basement during sunny days.
2. Use backyard PV to power the A7 during good sunlight hours.


The basement slab (and walls) get pretty cold during the winter.

About the same temperature as the water main coming into the house.
