Instead they are placed at some local high point, such as the highest point within a utility cupboard or boiler room, even though this is in a basement. European domestic gas boilers often include such a valve within the boiler casing itself. [1] An air release valve on an elevated section of a large diameter lavender-colored pipe

Early hot water systems were used in Ancient Rome for heating the Thermæ. [13] Another early hot water system was developed in Russia for central heating of the Summer Palace (1710–1714) of Peter the Great in Saint Petersburg. Slightly later, in 1716, came the first use of water in Sweden to distribute heating in buildings.
In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency.
A pressure vessel for the creation of hot water or steam, for residential or commercial use. Boilersmith A craftsman skilled in the techniques required for the construction and repair of boilers - not to be confused with at boilermaker (common misconception).

If this vent valve has not be opened sufficiently, the deaerator will not work properly, resulting in feed water with a high oxygen content going to the boilers. Should the boiler not have an oxygen-content analyzer, a high level in the boiler chlorides may indicate the vent valve not being far enough open. Some designs may include a vent ...
Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used). A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump.
One advantage of a boiler is that the furnace can provide hot water for bathing and washing dishes, rather than requiring a separate water heater. One disadvantage to this type of application is when the boiler breaks down, neither heating nor domestic hot water are available. Air convection heating systems have been in use for over a century.
