Scalding. Scalded thumb, two days after a radiator explosion. Scalding is a form of thermal burn resulting from heated fluids such as boiling water or steam. Most scalds are considered first- or second-degree burns, but third-degree burns can result, especially with prolonged contact. The term is from the Latin word calidus, meaning hot.
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 temperature varies.
Legionnaires' disease is a form of atypical pneumonia caused by any species of Legionella bacteria, [ 3] quite often Legionella pneumophila. Signs and symptoms include cough, shortness of breath, high fever, muscle pains, and headaches. [ 2] Nausea, vomiting, and diarrhea may also occur. [ 1] This often begins 2–10 days after exposure.
1,500 per year (US) [ 2] Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. [ 2] Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. [ 3] In severe hypothermia, there may be hallucinations and ...
In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [ 3][ 10] The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [ 2] Hyperthermia requires an elevation ...
Rate of deaths due to fire between 1990 and 2017. [] A thermal burn is a type of burn resulting from making contact with heated objects, such as boiling water, steam, hot cooking oil, fire, and hot objects. Scalds are the most common type of thermal burn suffered by children, but for adults thermal burns are most commonly caused by fire. [ 2]
New research finds the optimal room temperature range for sleeping for older adults. Here, experts explain the best temperature for sleep.
The valve gradually closes as the temperature of the surrounding area increases, limiting the amount of hot water entering the radiator. This allows a maximum temperature to be set for each room. As the valve works by sensing the temperature of the air surrounding it, it is important to ensure that it is not covered by material (such as curtains).
