Abstract: A method for determining whether water contained within a water pipe system in a building is at risk of freezing is disclosed. The method is carried out by a detector device comprising a processor. The method comprises determining a plurality of pipe temperature measurements using a temperature sensor. The processor analyses the pipe temperature measurements to detect whether a water draw has occurred. An exterior building environment temperature is compared to a predetermined freeze alert threshold. If the processor detects that (i) a water draw has not occurred; and (ii) the indicative temperature of the exterior building environment is lower than the predetermined freeze alert threshold, an alert is transmitted.

An annular retaining ring is provided to retain and center the disc on the burner element. The retaining ring includes a downwardly depending skirt to substantially close the stove opening. Inner downwardly depending tabs are provided to contact the stovetop reflector pan, thereby securely retaining the pad in place. An annular expansion joint is provided in the annular ring to accommodate thermal expansion/contraction of the disc. One or more circular grooves are provided on both the upper and lower surfaces of the disc to enhance the flexibility and resist any tendency to buckle due to thermal stresses.

Abstract: A flexible heat transfer pad for positioning on an electrical coil of the heating element on a stove. The pad includes two embossed metal plates with a metal alloy body sandwiched in between the two plates. The center section of the pad defined by the alloy body closely corresponds to the area of the electrical coil. An annular extension around the body includes opposite circular recesses for reinforcement of the pad. The upwardly extending recess forms a drip ring to confine any inadvertent overflow from a pan on the pad. A depending skirt around the drip recess extends over the rim of the heating element and substantially closes the stove opening. A liquid metal alloy body is preferably INDALLOY, a tin and bismuth alloy combination that melts at 281.degree. F. with no appreciable expansion or contraction during phase change or temperature transition. Other alloys or materials with similar properties can be used as a substitute material for the body as long as the melting point is approximately 140.degree.
