A submetering system typically includes a "master meter", which is owned by the utility supplying the water, electricity, or gas, with overall usage billed directly to the property owner. The property owner or manager then places their own private meters on individual tenant spaces to determine individual usage levels and bill each tenant for ...
Right in white-blue: the calculator; in the center in bronze: the ultrasonic flow meter . A heat meter, thermal energy meter or energy meter is a device which measures thermal energy provided by a source or delivered to a sink, by measuring the flow rate of the heat transfer fluid and the change in its temperature between the outflow and return ...
Heat from the space-heating boiler is transferred to the water heater vessel/container by means of a heat exchanger, and the boiler operates at a higher temperature than the potable hot water supply. Most potable water heaters in North America are completely separate from the space heating units, due to the popularity of HVAC / forced air ...
A typical water meter register showing a meter reading of 8.3 gallons. Notice the black "1" on the odometer has not yet fully turned over, so only the red hand is read. Water meters connected to remote reading devices through three-wire cables. There are several types of registers on water meters.
Central heating systems: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat pumps. [1] [2] Distributed heating systems: These systems generate heat in the space they are to heat, without extensive duct systems. Examples include electric space heaters ...
Common components of a central heating system using water-circulation include: A supply of fuel, electric power or district heating supply lines; A boiler (or a heat exchanger for district heating) which heats water in the system; Pump to circulate the water; Radiators through which the heated water passes in order to release heat into rooms.
The Spittelau incineration plant is one of several plants that provide district heating in Vienna, Austria. Animated image showing how district heating works. District heating (also known as heat networks) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water ...
The heat transfer coefficient has SI units in watts per square meter per kelvin (W/(m 2 K)). The overall heat transfer rate for combined modes is usually expressed in terms of an overall conductance or heat transfer coefficient, U. In that case, the heat transfer rate is: ˙ = where (in SI units):
