Hi everyone!
I've been doing field monitoring of residential space-heating and domestic water heating heat pumps for several years, using Campbell and other loggers. I've tested both air-source and geothermal heat pumps. My clients are generally electric utilities (IOUs and Co-ops) who want to gain experience with new, unfamiliar-to-them, or yet-unproven heat pump technologies.
I've learned some lessons over the years about measuring power, air temperature (it's not necessarily the constant across a duct), and air flow in cramped ducts.
I've always emphasized economy of measurement -- every data point should contribute to an Executive Summary-level result.
I will be glad to share experiences with others who have monitored heat pumps, and learn from you, too.

Russ, I am starting a project on heat pump monitoring and I am wondering how you went about collecting power data with the CS equipment.
