working principle of gas hot water boiler

Combi Boilers | What are Combination Boilers and How do

In most of the early designs of combination boiler, hot water from the heat exchanger passes to a diverter valve, which directs the flow to a domestic hot water calorifier or central heating circuit. The calorifier is tightly packed with small copper tubes, through which secondary water flows the moment the hot water draw off is opened.

Fuel oil - Wikipedia

Fuel oil (also known as heavy oil, marine fuel, bunker, furnace oil, or gasoil) is a fraction obtained from petroleum distillation.It includes distillates - the lighter fractions, and residues - the heavier fractions.. The term fuel oil generally includes any liquid fuel that is burned in a furnace or boiler to generate heat, or used in an engine to generate power.

Heat pump water heaters working principle

The heat pump water heater uses the operational principle of a heat pump, by absorbing calories in outdoor air and using this energy to ensure water heating. The fan (1) inhales ambient air transferring its energy to the refrigerant agent in the evaporator (2) thus changing from liquid to gas.

Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

Gas-Fired Boilers and Furnaces | Department of Energy

An aquastat controls the temperature of the hot water in a boiler, typically keeping it around 180°F. But when heating needs are lighter in the spring and fall, that's actually higher than needed, and wastes energy. A modulating aquastat, also called an outdoor reset, senses outdoor temperatures and adjusts the hot water temperature accordingly.
