When used for space heating, an air-to-water heat pump fills the role usually held by a boiler; it requires a hydronic (water-based) distribution system. The heat pump makes hot water; the hot water can be pumped through fin-tube baseboard units, in-floor PEX tubing, or a fan-coil unit. (A system with such a fan-coil unit is called a hydro-air

Get priceBoiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted. Today, all boiler feed pumps are centrifugal pumps. The design of boiler …
Get priceEnergy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler. Energy output (boiler thermal efficiency) is between 75 and 77 percent.
