Earth Notes: On 16WW Mains Inlet Water Temperature

Updated 2024-11-30.

Domestic mains water temperature data for 16WW on tap; seasonal min/max about 10C/20C in winter/summer. #dataset #water #temperature

FAQ

What is the domestic water mains temperature range seen at this suburban London kitchen tap?

Typically between about 10°C and 20°C (winter vs summer). Extremes of 6°C (2010-01-09) and 25°C (eg 2018-07-26) have been observed between 2008 and 2019 inclusive.

Is this a highly scientific study?

No. The probe is not calibrated, but the results are fairly consistent and plausible.

Water Temperature Samples

A data set of regular samples of domestic mains water infeed temperatures in suburban London (UK). Useful for estimating required temperature 'lift' and therefore energy demand for DHW (domestic hot water), washing machines and dishwashers ("wet white goods"), for example. Available in CSV and MIDI (sonified) formats.

The HTML table below is laid out to be easy to parse with text processing tools, eg to convert into CSV or load into a spreadsheet, if required.

Method

measuring mains water temperature at kitchen sink with N84FR

Water temperature is measured at the 16WW kitchen tap (which is close to the water main feed to the property) running a fast-flowing stream.

The probe tip is placed up inside the tap nozzle with the tip not touching anything if possible.

Typically at least 20s is allowed until the temperature reading settles. The value is then recorded in the table below.

The measuring device is a Maplin N84FR digital probe thermometer (uncalibrated) from 2008-08-30. K-type thermocouple. Range -20°C--1000°C. (Note battery (2xSR44) changed 2015-09-15; again 2018-08-14.)

The aim is to measure near (solar) noon where possible, and near the middle of each calendar month to be representative for that month. There are some extra and missing samples.

Outside temperatures are taken from inspection of live measurements in the shaded porch near the kitchen, and/or from local weather reports.

Code

Code to extract data from this HTML file can be found at script/16WW-mains-water-inlet-temperature-toCSV.sh.

Basically a small sed script extracts the data lines from the HTML and converts them to a more simple CSV format for other tools to process. The CSV consists of the date (ISO 8601 format, no time) in the first column, and the recorded temperature in integer Celsius in the second. (Rows with decimals would be dropped.)

A sample output line is:

2019-10-14,17

Some months have multiple readings. (Some have no readings.) To make some subsequent processing easier, the script script/16WW-mains-water-inlet-temperature-month-filter.sh discards all but the first reading for each month.

There are other similar scripts available.

Thames Water said due to freezing weather water had cooled to a "staggeringly chilly" 1.8C. Until now the coldest water temperature recorded was 4.9C in 2001 - the average is 7.3C.
