Abstract: An apparatus and method for measuring the efficiency of a heating system in which the temperature of the flue, or stack, is measured during a heating cycle and data collected to show the elapsed time and maximum temperature achieved. This data is compared to predetermined limits and if the elapsed time and/or the maximum temperature exceeds the predetermined limits, an error message is generated that may be video, audio, and/or an email sent to a predetermined email address. Other statistics may be generated and temperature data from more than one heating cycle may be aggregated together.

Abstract: A suspension system for use in a laundry washing machine to suspend a tub assembly from a base portion of a cabinet. The suspension system includes a support frame interconnected to an outer tub of the tub assembly and a plurality of isolation damper units for resiliently coupling the support frame to the base portion of the cabinet. The isolation damper units function to allow limited lateral movement of the tub assembly relative to the cabinet while also providing a “return to center” feature. The isolation damper units are further operable to inhibit rotation of the outer tub relative to the cabinet. Finally, the isolation damper units function to absorb the vibration transmitted through the tub assembly to the support frame so as to minimize transmission of such vibration to the cabinet.
