Among other things, the Americans with Disabilities Act (ADA) ensures access to the built environment for people with disabilities. The ADA Standards establish design requirements for the construction and alteration of facilities subject to the law. These enforceable standards apply to places of public accommodation, commercial facilities, and state and local government facilities.

This is the temperature that one feels in a room.
An ampere or amp (represented by the A symbol) is the SI unit that measures the intensity of an electric current.
Anodizing is a conversion-type surface treatment using anodized oxidation (applying an electrically insulating layer between 5 and 50 micrometres) to protect or decorate a part made of aluminium (or alloy) or titanium (or alloy). It makes materials more resistant to wear, corrosion and heat. The thickness of the finish varies according to the intended use of the final product.
This mode enables the room to reach the selected temperature at the programmed hour. In fact, the thermostat estimates the delay required to reach the set point of the next period at the programmed hour. This delay is obtained by the observation of the temperature variations in the room and the results obtained during the preceding anticipated starts. That way, the results should be increasingly precise day after day.
This convection heater will provide heat its whole length by creating a curtain of warm air. It can span the length of a wall with the available Stelpro accessories.
An audit is a professional examination by a competent and unbiased expert who renders a judgement on the financial state, internal control, organization, process or operation of an entity.
The audit is an ongoing improvement tool, as it takes stock of existing inventory in order to identify weak or non-conforming points (according to the audit's guidelines). The results are formally written up in a report, so that the appropriate action can be taken to correct discrepancies and deficiencies.
Automatic reset thermal protection
This protection shuts off a device in case of extreme temperature fluctuations. It automatically resets once the device resumes functioning under normal conditions.
BTU (British Thermal Unit) is the unit that measures the amount of heat required to raise the temperature of a litre of water by one degree Fahrenheit. In heating and air conditioning, BTU indicates the amount of heat that can be given off by a device.
This is a secondary heating system that complements the main one. It's used when more heat is needed in a room.

A ceiling fan heater is a very powerful device combining convection and forced air. This heater is installed on the ceiling and uses natural convection to produce heat, but it also contains a powerful fan that propels this heat towards the floor. In fact, the ceiling fan heater recycles heat that rises to the ceiling and constantly re-directs it towards the floor. The Stelpro Spider (SGH) is one of the most popular types of ceiling fan heaters.

A heating device installed under glass surfaces, which can span the length of a wall, to ensure uniform heating throughout the room. It was designed to be set back from furniture, so that furniture either hides it or it does not get in the way of furniture that is being moved around. Some models are fitted with a sloping top, so that books or other objects cannot be placed on top of it, which could hinder its performance. The CBB and CBF are two types of popular commercial baseboards manufactured by Stelpro.
Stelpro consoles are convection devices convenient for many applications. Whether installed on a wall or ceiling, Stelpro consoles live up to their reputation. Thanks to their robust housing, they can also be installed on concrete walls or recessed into regular ones. Stelpro consoles come with a wide range of power settings, as well as adjustable air inlets and outlets.
Generally speaking, a control is a set of techniques used to maintain the stability of a function. In Stelpro's case, this function is temperature.
Heat transfer is triggered by the movement of air that carries along the energy contained within. Convection can be natural (or free) when the heat exchange itself is at the origin of the movement of air. It is forced when the air is circulated by a mechanical device.
A convector is a heating device that uses the principle of natural convection to heat a room environment. It's a simple structure consisting of metal housing with an opening in the bottom part and another in the top part. The heating element is in the bottom part of the housing. Cold air enters the convector from the bottom, where it is heated, dilates and becomes less dense, then rises up inside the housing, pushed upwards by denser cold air, and finally escapes through the top. This hot air movement continues for as long as the heating element is operating. Stelpro's SIL and SHC models are two of the most trusted names in the convector market.
Stelpro is the first manufacturer to coin the term convector-baseboard to define its innovative electric baseboard with rounded corners. This is a more appropriate definition for this kind of device that uses natural convection. The B model by Stelpro is one of the most trusted convector-baseboards on the Canadian market.
A device used to create a link between two systems. It can be mechanical, electronic, and is often a combination of different technologies.

A fuse protects all electrical connections from an accidental current increase, thereby interrupting the current in case of electrical (overheating) fault.
Geothermy (or Geothermics)
From the Greek geo (earth) and thermos (heat), geothermy is a word with a dual meaning: It refers to the scientific study of the earth's internal thermal phenomena and to the technology used to exploit it. By extension, geothermy sometimes refers to geothermal energy, which is energy from the earth converted into heat.
Ground fault circuit breaker (or interrupter)
A circuit breaker electrically isolates and protects different electronic circuits in a home, i.e. against over-currents. Unlike a fuse, a circuit breaker can be reset.
Ground leakage current
This can occur due to deterioration inside conductors, which causes a fault current to move from the ground receptor to the ground.
Grounding protects people against electric shock when they use a device with an electrical fault. It also protects system materials inside the device. All electrical equipment is grounded with a conductor, so that the fault electric current is discharged into the ground.

A heating cable or floor is a heat emission process designed to heat a room using the floor surface to heat the interior air. The concept consists of heating a room by distributing minimal heat over a large surface area (the floor of the room). This is one of the most comfortable, affordable, clean and aesthetic heating systems on the market.
A heating element is an electrical component that, thanks to the Joule effect, produces heat by converting the electric current that passes through it.
Infrared heaters heat solids rather than air. The heat is stored in the interior walls and furniture, which re-diffuse it even longer. Infrared radiant heaters do not circulate air, so they do not circulate dust and cause related inconveniences. The air has a lower dust level and is thus healthier. Stelpro manufactures the SIRH and SCR radiant heaters, two of the most trusted names in infrared heaters.
Leadership in Energy and Environmental Design (LEED) is a North American standardization system for high-quality environmental buildings. The term was coined by the US Green Building Council in 1998. There are four levels of LEED for buildings: certified, silver, gold and platinum. LEED evaluation criteria includes: energy efficiency, water consumption efficiency, heating efficiency, using locally produced materials and reusing any surplus of these materials.

Nichrome is silver-grey in colour, anti-corrosive and reaches its melting point at around 1400°C. Nichrome is widely used in heating elements due to its highly resistant properties, especially to oxidation at high temperatures.
