Condensing boiler - Wikipedia

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.

Central heating - Wikipedia

Overview. Central heating differs from space heating in that the heat generation occurs in one place, such as a furnace room or basement in a house or a mechanical room in a large building (though not necessarily at the geometrically "central" point). The heat is distributed throughout the building, typically by forced-air through ductwork, by water circulating through pipes, or by steam fed

Central Heating System - an overview | ScienceDirect Topics

The most common centralized heating systems in both residential and commercial spaces typically involve using a flame to heat and move a heat transfer fluid via forced hot air, pumped hot water, or steam delivery. 4 As per Krigger and Dorsi, these centralized oil, gas, and/or propane heating systems mix and burn fuel in a combustion chamber, and the heat from the flame and combustion gases are

Combining a geothermal heat pump with a boiler | 2016-01

Jan 11, 2016 · During heating mode, the heat pump and mod/con boiler can supply heat to the buffer tank, individually or together, depending on the load requirement. Given the unit cost of heat from the heat pump is usually lower than that from the boiler, the heat pump provides first-stage heat input with the boiler taking up the slack, as necessary

Boiler Fundamentals and Best Practices

From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2, kpa Steam

Combi Boilers | What are Combination Boilers and How do

Combination boilers combine the functions of a central heating boiler and an instantaneous multi point water heater. They give priority, in the main, to the supply of domestic hot water (dhw). The combination boiler has all its operating components contained within the casing and is typically designed for use within a sealed central heating system.

Case studies of Low Temperature District Heating systems

Some heat exchangers are designed to increase turbulence and thereby improve heat transfer (which is seen in the boiler output/input ratio). These designs can increase forced draft fan motor power, and full/part-load fan power should also be included in the evaluation of options (see Section 3.1.6 VFD Forced Draft Fan).

Central Heating Boiler Systems | A Guide to the Different

Boiler is a closed vessel in which water is converted into steam by the application of heat. Usually boilers are coal or oil fired. A boiler should fulfill the following requirements (i) Safety. The boiler should be safe under operating conditions. (ii) Accessibility. The various parts of the boiler should be accessible for repair and maintenance.
