The British thermal unit (BTU or Btu) is a unit of energy used globally in the power, steam generation and heating and air conditioning industries. Although it is in common use in these industries, in scientific use it has been replaced by the SI unit of energy, the joule (J). In North America, the term "BTU" is used to describe the heat value (energy content) of fuels, and also to describe the power of heating and cooling systems, such as furnaces, stoves, barbecue grills, and air conditioners. When used as a unit of power, BTU per hour (BTU/h) is understood, though this is often confusingly abbreviated to just "BTU". In the UK and other parts of the world it is written BTU. One Watt is equivalent to 3.41 BTU/hr.

A Chalk Line is used to create straight lines over a long distance. A length of string, saturated in chalk, is stretched across the distance to be marked. The string is pulled tight and each end is pressed against the surface to be marked at beginning or ending points. The middle of the string is then pulled away from the surface to be marked while the end points remain pressed against the surface. The middle is released and strikes the surface to be marked, leaving a straight line of chalk on that surface. In outdoor conditions a clear polyurethane will be sprayed over the line to protect it from rain and snow. Chalk lines are frequently used by Heatizon Installers to mark where grooves should be sawcut in retrofit applications.

A thermostat is a device for regulating the temperature of a system so that the system's temperature is maintained near a desired setpoint temperature. The thermostat does this by controlling the flow of heat energy into or out of the system. That is, the thermostat switches heating or cooling devices on or off as needed to maintain the correct temperature. Thermostats can be constructed in many ways and may use a variety of sensors to measure the temperature. The output of the sensor then controls the heating or cooling apparatus.

A timer is a specialized type of clock. A timer can be used to control the sequence of an event or process. In radiant heating applications, timers can be used to manually turn on a system and then automatically turn it off after a set amount of time.
A transformer is a device that transfers electrical energy from one circuit to another by magnetic coupling without requiring relative motion between its parts. It usually comprises two or more coupled windings, and, in most cases, a core to concentrate magnetic flux. An alternating voltage applied to one winding creates a time-varying magnetic flux in the core, which induces a voltage in the other windings. Varying the relative number of turns between primary and secondary windings determines the ratio of the input and output voltages, thus transforming the voltage by stepping it up or down between circuits.
