Swimming in a pool is a great way to get a low-impact workout, stay cool during heat waves and generally boost your mood. But it’s not all floaty fun — pools come with a few risks too. Aside ...
For example, a conventional heat pump system used to heat a building in Montana's −57 °C (−70 °F) low temperature or cool a building in the highest temperature ever recorded in the US—57 °C (134 °F) in Death Valley, California, in 1913 would require a large amount of energy due to the extreme difference between inside and outside air ...
Winter swimming is the activity of swimming during the winter season, typically in outdoor locations ( open water swimming) or in unheated pools or lidos. In colder countries, it may be synonymous with ice swimming, when the water is frozen over. This requires either breaking the ice or entering where a spring prevents the formation of ice.

The term encompasses a broad range of approaches and therapeutic methods that take advantage of the ...
One option is temperature control—i.e., keeping all cold water below 25 °C (77 °F) and all hot water above 51 °C (124 °F). [3] Temperature affects the survival of Legionella as follows: [3] Above 70 °C (158 °F) – Legionella dies almost instantly; At 60 °C (140 °F) – 90% die in 2 minutes (Decimal reduction time (D) = 2 minutes)
Designated as an American National Standard, the Uniform Swimming Pool, Spa and Hot Tub Code (USPSHTC) is a model code developed by the International Association of Plumbing and Mechanical Officials to govern the installation and inspection of plumbing systems associated with swimming pools, spas and hot tubs as a means of promoting the public's health, safety and welfare.
Spent fuel pools ( SFP) are storage pools (or "ponds" in the United Kingdom) for spent fuel from nuclear reactors. They are typically 40 or more feet (12 m) deep, with the bottom 14 feet (4.3 m) equipped with storage racks designed to hold fuel assemblies removed from reactors. A reactor's local pool is specially designed for the reactor in ...
Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses. Domestically, water is traditionally heated in vessels known as water heaters ...
