2018 MHA Research Heater Tests

Test MHA-1802
January 16, 2018

Red oak, same fuel batch as last test series of 2017
Log cabin stacking, top ignition
62.0 lbs including 2.0 lbs kindling
21.7% moisture. 2345 stacking.

Pisla HTT 602 door, 22" wide
Austrian eco firebox, see  http://www.heatkit.com/research/lopez-2014-03-01.html

This series is a "Substantially Similar" study for possible use in certifying factory made heaters,
to allow laboratory testing on one model to apply also to variations in the heat exchanger on that model.

For this run, we are repeatingthe last series of 2017 as a baseline for comparison.
See 2017 Run #16 (final run of 2017)


Condar spreadsheet results, calculated at 90 minutes.
With the eco-box, the test is over when the air supply is closed. Remaining charcoal would normally be burned in the next fire.
