Warming Up

It's up to 75 F right now.  I just shut off the floor heat for the 1st time since the 6th or 7th.  (The circulation pump is on but the heater is off.) The greenhouse is warm in the sun and I plugged in the blower which sends the heat inside.

At 6:15 pm I turned on the valves that sent water to the deep loops.  It's 78 degrees inside.  I turned off the air blower and shut the greenhouse door about 4 pm.

Oops.  

Those weren't the deep loops, they were the greenhouse loops, which were empty.  I might've fried the pump.
