calorimeters should have a low heat capacity
Emergency Heat [EM] should only be used as a backup if the heat pump fails. EM heat uses 1.5 to 3 times as much or electricity as the heat pump.
The heat on your oven should be set to 300 degrees for braising meats.
On a system that uses a Heat pump, the heat setting utilizes the pump, and electrical coil heating as a backup. On the EM setting the heat pump won't run, only the axillary coils will provide heat.
If the reaction is endothermic in nature then heat should be added to it,otherwise all chemical reaction neddn't heat always.
That really depends on what you are trying to heat and how you are heating it.
