Set the water heater to 140F and then set the timer to only turn on at night. Then use a recirculating pump and fan coil to extract the heat during the day.

For storing cold, find a used A/C condensing unit, some copper tubing, and an expansion valve. Coil the tubing in a garbage can filled with water and use the A/C to freeze the water during the night. Use another copper coil and an antifreeze solution (pumped through a surplus car radiator or similar) to extract the cold for use during the day.
