Designated as an American National Standard, the Uniform Solar, Hydronics and Geothermal Code (USHGC) is a model code developed by the International Association of Plumbing and Mechanical Officials to govern the installation and inspection of solar energy, hydronic heating/cooling systems, and geothermal energy systems as a means of promoting the public's health, safety and welfare.
Depiction of New York World Building fire in New York City in 1882. Building codes in the United States are a collection of regulations and laws adopted by state and local jurisdictions that set “minimum requirements for how structural systems, plumbing, heating, ventilation, and air conditioning (), natural gas systems and other aspects of residential and commercial buildings should be ...
The product had the word "chrome" stamped on the strip heater and used a cement mix to "lock" in the heating element, hence the name "Chromalox." The company continued to grow and developed a Pittsburgh manufacturing presence in the 1920s, developing new industrial heating products and processes.

Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used). A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump.
In thermodynamics, the Helmholtz free energy (or Helmholtz energy) is a thermodynamic potential that measures the useful work obtainable from a closed thermodynamic system at a constant temperature . The change in the Helmholtz energy during a process is equal to the maximum amount of work that the system can perform in a thermodynamic process ...
A building's HVAC (heating, ventilating, and air conditioning) system can make use of an air-side economizer to save energy in buildings by using cool outside air as a means of cooling the indoor space. When the temperature of the outside air is less than the temperature of the recirculated air, conditioning with the outside air is more energy ...
Citizens Energy Corporation is a non-profit organization that primarily aids poor and elderly households in Massachusetts and internationally by organizing projects to provide discounted and free home heating services and supplies. They also construct power generation and transmission systems.
