It dropped below freezing again last night here in Williston, Florida, but not by much.  This weather is not unusual for this time of year, and therefore not unexpected.  We normally use our three electric toe-kick heaters and our Broan ceramic cube heater to ward off the chill but when the outside temperatures get down towards freezing we use the Aqua Hot (diesel fueled hydronic heating system).

The unit has been running fine, but this morning I noticed that the coach had cooled off a bit. I checked the blowers on the bedroom and bathroom heat exchangers and the air coming out of them was not warm.  I checked the main unit (in one of the bays) and while the burner appeared to be running the feed lines were cool to the touch.  Normally they would be quite warm.  I turned off all three thermostats (bedroom, bathroom, and living room) and shut off the main switch that controls the burner.  The coolant in the overflow reservoir was at the add mark, so added some.  I turned the unit back on, turned on all three thermostats, and set them high enough to call for heat.  A short time later we had heat again.  The fans for the living room heat exchanger even came on (they haven’t been working the last couple of days).  Ahhh, the mysteries of the motorhome.  I added to much coolant, so of course it overflowed when it came up to temperature.

The weather was cloudy all day and the high temperature barely broke 50 degrees so we stuck around the RV resort.  Linda continued working on the needlepoint she is doing for Madeline and I started working on a featured bus article for Bus Conversions Magazine.  At the Arcadia Bus Rally I had the opportunity to interview Jimmy and Sadie Clay and photograph their 1984 Eagle Model 10 conversion “Iron Horse.”  The interior is done to resemble a railroad car from the Old Wild West.  I did not have a finished draft by bedtime, but I made excellent progress.

We took our usual walks and Linda made stuffed acorn squash for dinner using some leftover rice and other ingredients she had on hand.  She served it with a side of Brussels sprouts that she browned and then steamed.  Simple but delicious, and very satisfying on a cool evening.
