Boiler - Wikipedia

2019-10-13 · A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications,[1][2] including water heating, central heating, boiler

Balanced and Conventional Flues Explained - PD

Conventional flues rely on the natural circulation of heated air to take smoke and combustion gases away from the source of combustion, e.g. a fireplace, stove or gas or oil-fired boiler. The air required for combustion is drawn from the air surrounding the stove or boiler it is not supplied by the flue. This is where balanced flues differ.

Types of Home Heating Systems - The Spruce

Standard home systems are air-source heat pumps that draw heat from the outdoor air. There are also ground-source, or geothermal, heat pumps that pull heat from deep in the ground as well as water-source heat pumps that rely on a pond or lake for heat. A popular type of air-source heat pump is the mini-split, or ductless, system.

Evaluation of retrofitting a conventional natural gas

The exit flue gas temperature of a conventional gas fired boiler is usually high and a great amount of heat energy is lost to the environment. If both sensible heat and latent heat can be recovered by adding a condensing heat exchanger, the efficiency of the boiler can be increased by as much as 10%.

Condensing boiler - Wikipedia

2019-10-15 · Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.
