BTU Performance Monitoring - Measuring Your Savings

While the HotSpot heat recovery system performance has been fully documented with AHRI testing and is therefore highly predictable, some customers wish to record and/or view their actual heat recovery BTU performance data. Fully automated integrated BTU monitoring systems are expensive and can often cost as much as a complete, fully installed heat recovery system. However, HotSpot has developed two simple, accurate and low cost BTU monitoring solutions.

One solution, the LCD Display BTU Meter, mounts indoors near your hot water tank and displays instant and cumulative BTU data. The other solution is a pure Data Logger that mounts outside (in a weather tight housing, attached to the HotSpot remote unit) and does not have a display, but you can move the data off of the unit onto a PC to create spreadsheets. The data logger solution is a semi-automated system, and holds 30 days worth of data. Significant user participation is required for the data logger.

Another option is to use the data logger solution without the expense of an installed flow meter and save $105. The flow can be calculated, or measured with an ultrasonic flow meter without penetrating the pipe.

Dealers: HotSpot can allow you to take advantage of a special deal we have on ultrasonic flow meters. Contact your HotSpot account manager for details.
