Is it possible a family member will need care within the next 5 years? If not could you benefit from a bulky but inexpensive energy storage - thermal mass with the charge coming from an antifreeze-filled solar water panel to the mass, then another circuit coupling the radiant floor heating ? Or electric where you're charging cheap but heavy lead acid cells (with thorough ventilation + at least one backup ventilation system) during the lowest usage times + PV and reselling back to the utility during peak usage?
From a more fun side, how about a large hot tub or "endless" swimming pool? Could even try out the swimming pool and if you don't use it convert it to a battery.
