Blow through direct fired heating, A/C and ERV

According to various aspects, exemplary embodiments are disclosed of direct fired heaters including premix burner technology and/or feed forward control loop modulation via inlet air temperature.

Direct fired heaters including premix burner technology

A gas heater with specialized controls allows an operator to deploy a single device to heat and to dry when extracting moisture from a structure. The heater has a fan in a blow thru arrangement ahead of a burner. The burner uses either natural gas or liquefied petroleum gas. The heater has air flow, fan motor, temperature, and ignition controls and sensors. The heater delivers high temperature air to the structure that hastens evaporation as the heated air absorbs great concentrations of water vapor. Then the moisture laden heated air exits the building as the heater draws in fresh air, ducts it into a structure, and pressurizes the structure. This moisture laden air then leaks from the building through select windows using the energy imparted from the fan and then exhausts the moisture to the atmosphere, drying the structure.

Heater and controls for extraction of moisture and biological organisms from structures

Exemplary embodiments of the present disclosure include devices for monitoring and indicating the completion of eradication of a pest infestation in a space in which heating is utilized for eradication. In an exemplary embodiment, a device includes a sensor configured to sense temperature proximate the device, and a visual indicator configured to provide indication of status. The device further includes a processor that is connected to the sensor and visual indicator. The processor is configured to determine whether the sensed temperature exceeds the MINIMUM LETHAL TEMPERATURE, and configured to determine occurrence of completion of a minimum heating duration required for eradication in which the sensed temperature exceeds the MINIMUM LETHAL TEMPERATURE. The processor is further configured to activate the visual indicator subsequent to completion of the minimum heating duration, to thereby provide visible indication that the minimum heating duration for eradication of a pest infestation has elapsed.
