O
perators,
every 6 months, recharge the battery pack,
in your 35,000-BTU and 60,000-BTU convective space heaters. A discharged battery
pack that sits around for a long time may be impossible to recharge. And replacing the
pack costs more than $900.
When
you
operate
the
convective space heater, the
battery pack gets recharged by
the
thermoelectric
generator
(TEG) on the heater. That’s Fne
during colder months when the
heater’s running a lot. But it’s
a different story during warmer
months when the heater sits idle
for a long time. That’s when the
pack typically goes uncharged.
