A switching or variable-voltage system (also known as a "wavemaker") is commonly used in reef aquaria to more closely simulate the movement of ocean water. [1] Water circulation is vital to proper biological filtration of most saltwater aquaria (particularly those using the Berlin Method), and is useful in freshwater aquaria for allowing free ...
A circulator pump for home use. A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit with small elevation changes. They are commonly found circulating water in a hydronic heating or cooling system.

A forced circulation boiler is a boiler where a pump is used to circulate water inside the boiler. This differs from a natural circulation boiler which relies on current density to circulate water inside the boiler. In some forced circulation boilers, the water is circulated at twenty times the rate of evaporation. [1]
forced-circulation boiler: boilers where circulation is forced by a pump, rather than relying on thermosyphon effect. These may use either forced-water-circulation (e.g. La Mont) or forced-steam-circulation (e.g. Löffler). [25] Foster-Wheeler boiler. D type; controlled-superheat type; ESD type (External Superheat, D type) Franco-Crosti boiler ...
A thermal immersion circulator comprises a circulator pump or motorized impeller to move the fluid, a heating element immersed in the fluid, an accurate temperature probe, and control circuitry which compares the measured temperature with the desired value and supplies power to the heater as required to stabilize the temperature.
An aquarium heater is a device used in the fishkeeping hobby to warm the temperature of water in aquariums. [1] Most tropical freshwater and marine aquariums are maintained at temperatures that range from 22 to 30 °C (72 to 86 °F). [1] [2] [3] The types include glass immersion heaters and undergravel heating. There are also heating mats that ...
Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.
