Steam vs. Hot-Water Heating

Jun 23 2014 · Steam explosions of course opened the door for the hot water people and gravity hot water heating arrived as a gift from the Canadians. Mark Honeywell took the gravity system and made it better. The steam people had to respond so they came up with the concept of vapor heating which is a system that runs on eight-ounces of pressure or less.

Difference Between Low- and High-Pressure Boilers | Hunker

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.

Whats the Difference Between Atmospheric Vent and Power ...

Jun 09 2016 · The atmospheric venting heater is the oldest type available. With this system fuel is heated and it warms the water. The pressure of the combustion pushes excess gas upwards and out your chimney. Enough fuel must remain in the tank once the water is heated to allow enough pressure to push these gases upwards and out.

Characteristics of boiler feedwater - Lenntech

Water absorbs more heat for a given temperature rise than any other common inorganic substance. It expands 1600 times as it evaporates to form steam at atmospheric pressure. The steam is capable of carrying large quantities of heat. These unique properties of water make it an ideal raw material for heating and power generating processes.
