Hot water reset. Hot water reset, also called outdoor reset ( ODR ), is an energy-saving automatic control algorithm for heating boilers that are typically fired with fuel oil or natural gas. A hot water reset control loop measures the outside air temperature; this information is used to estimate demand or heating load as the outdoor ...
Hydronics (from Ancient Greek hydro- 'water') is the use of liquid water or gaseous water or a water solution (usually glycol with water) as a heat-transfer medium in heating and cooling systems. [1] [2] The name differentiates such systems from oil and refrigerant systems.

New Straitsville was founded in 1870 as a coal mining town by the New Straitsville Mining Company. The town grew quickly and by 1880 the population was over 4,000 people. The coal mining activity ended in 1884, when a labor dispute at the mine ended with a group of miners sending a burning coal car into the mine, igniting the coal.
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 ...
