I've owned and have been running my Garn Jr. for over a year now, and I've been very pleased, but I find on windy days or single-digit nights, I can't seem to stay up to the thermostat set temp. It's been mildly windy and lows in the teens here in west Michigan lately, and like a handful of times since starting with my new heat source, I'm findings nights or even days that the furnace simply will not keep up! That has been the case the last couple of days (windy & cold), and the house temperature starts to rise as I get the water back up to 160 degrees+. Thermostat is set to 68 and at temp when I start a small, final fire at 12:30pm. Woke up the following morning (6:00am) and it was 64 in the house. What's interesting is that my tank temp was still at 140, but somehow not able to catch up or keep up with the fan continuing to blow!
Perhaps it's as simple as a bigger pump? Maybe I need to address some insulation issues...? A bigger coil in the furnace plenum? Taking all considerations at this point. Thankfully, if tended to by keeping the tank temp high, I'm able to combat the issues...but something has to give, right? Thanks all!
Hopefully the information below of my setup below is helpful...
Lines: 1"
Heat loss through lines: Very minimal to non-existent
Pump: Badger 20 GPM 3 speed, set at highest speed
Other uses: DHW, separate deliver and return lines from furnace
House: 2,000sq.
Garn: In pole barn, well insulated, steel stud and drywall
