How do I control the temperature of water for an extended period of time?
When making the "perfect" mash, Heston Blumenthal recommends cooking waxy spuds in hot water for half an hour at the temperature of 72 degrees Celsius, exactly. At 75 degrees stuff starts breaking down.
I would like to try this out but am unsure how I can keep the temperature constant.
What kitchen tools and process can I follow to measure the temperature throughout the process? Are there any tricks?

You can try to set up my at-home on-the-cheap monkey-at-the-controls sous-vide machine. I take a nearly full 22 quart stock pot with an analog instant read thermometer to monitor the temperature and watch the temperature and adjust the dial accordingly.
With this only needing 30 minutes you probably just want to get the water to exactly 72 degrees C and then immerse the potatoes without adding any heat. The amount of energy in 20 quarts of water is phenomenal and you won't lose a lot of heat to the air.
Alternatively you could get 72 degree water and a beer cooler and try that way for the extra insulation.

How do you keep the temperature of water constant?
To fix this problem, consider installing a mini-mixing tank with your heater. These mini tanks do not store water; they hold a small amount of water back, mixing the cold water in with hot before it gets sent down the line, providing you with a more constant water temperature.How do you control the temperature of water?
Depending upon exactly what kind of faucet you have, different valve-like devices, such as mixer taps, single handle mixers, temperature control valves, and thermostatic mixing valves, are used to regulate the temperature of the water before it comes out of the spigot.How does the temperature of the water change over time?
Heat transfer, whether from the air, sunlight, another water source or thermal pollution can change the temperature of water. Water temperature plays a major role in the quality of aquatic life and habitats. Heat flow and the fluctuation of temperature determine what species will live and thrive in a body of water.What affects water temperature?
Therefore, the temperature is largely determined by the selection of the raw water source and the depth of the intake. In Canada, surface water temperature shows a wide seasonal variation in most localities (2\xbaC \u2013 25\xbaC). Algal growth in surface water normally becomes noticeable only at temperatures above 15 \xbaC.How to Increase Hot Water Temperature | Water Heater Adjustment
