Abstract
The results of a full annual cycle of detailed monitoring of ten domestic ground source heat pump systems installed in similar properties are presented. The monitoring scheme used was designed to allow full characterization of the system, including monitoring of the heat supplied by the pump to both space-heating and domestic hot water, and also monitoring of the energy consumption of the various heat pump constituents. This approach is contrasted with a more commonly adopted approach where seasonal performance factors (SPF) are obtained without invading the heat pump enclosure. A number of issues are discussed which can lead to significant inconsistencies in the latter approach. Quantitative differences in the SPF obtained by the two methods are calculated or estimated for the monitored systems. Generally, the simpler approach leads to underestimation of the SPF by an amount which is variable and dependent on factors such as domestic hot water usage, pump settings and precise meter locations.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
