Mobile heating apparatus and method

A mobile heating apparatus to heat a space for the treatment of bed bugs within the space, the mobile heating apparatus comprising:

• an air mixing chamber;
• a fresh air inlet, including a blower, extending from outside the space to the mixing chamber;
• a recirculation air inlet extending from inside the space to the mixing chamber;
• a heating chamber;
• a burner;
• a fuel source outside the space connected to the burner;
• a heat exchanger operatively connected to the burner, disposed in the heating chamber
• a conduit for directing air from the air mixing chamber past the heat exchanger to heat it;
• an outlet, including a blower, for directing heated air into the space;
• a first carbon dioxide (CO) sensor associated with the fresh air inlet;
• a second CO senor associated with the recirculation inlet;
• and
• a control, responsive to the first and second CO sensors for disabling the burner if the first CO sensor detects a CO level in the fresh air in excess of a first predetermined level, and disabling the burner if the second CO sensor detects a CO level in excess of a second predetermined level that is higher than the first predetermined level.
