1. A boiler and heating system protection apparatus comprising:

  • (a) a control board having at least one input and at least one output;

    (b) a processor having at least one input and at least one output;

    (c) at least one ambient sensor located outside an enclosure to be heated by a heating system or in a heating zone of the heating system, said ambient sensor being in communication with the processor through the at least one input wherein said ambient sensor is capable of detecting ambient temperature;

    (d) at least one boiler sensor located in one or more boiler sections or in a manifold of a boiler, said boiler sensor being in communication with the processor through the at least one input wherein said boiler sensor is capable of detecting boiler temperature or boiler water level;

    (e) an alarm relay connected to the control board by the at least one output and which is capable of sending notification to an alarm system;

    (f) a power failure relay, said power failure relay being in communication with the processor through the at least one input wherein said power failure relay is capable of detecting power failure of the boiler;

    wherein when an ambient temperature detection event occurs the ambient sensor communicates with the processor and switches the control board from passive mode to monitoring mode;

    wherein when a temperature detection event occurs the boiler sensor communicates with the processor and initiates an alarm pathway to prevent damage to the boiler and heating system due to extreme temperatures;

    wherein when a heating system malfunction occurs the power failure relay or the boiler sensor communicates with the processor and initiates an alarm pathway to prevent or minimize damage to the boiler and heating system; and

    wherein the processor provides for the boiler to return to normal function when the temperature detection event or the heating system malfunction ends.
