  • Types of Heating Systems | Smarter House

    Boilers are special-purpose water heaters. While furnaces carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house. The cooler water then returns to the boiler to be reheated. Hot water systems are often called hydronic systems.Learn More

  • Waste Heat Recovery Methods And Technologies - Chemical

    Jan 01, 2013 · Economizers for boilers. An economizer recovers waste heat from fluegases by heating BFW, and hence reduces boiler fuel requirements. Flue-gases are often rejected to the stack at 30 to 70°C higher than the temperature of the generated steam. Generally, boiler efficiency can be increased by ~ 1% for every 22°C reduction in fluegas temperature.Learn More

  • HEAT RECOVERY BOILERS

    The convective elements of boilers fired by municipal industrial or other waste materials are often referred to as heat recovery boilers although, apart from their geometry, they are more akin to the rear end of a furnace-fired boiler. Perhaps the most common heat recovery boiler is now the gas turbine heat recovery boiler.Learn More

  • Furnaces and Boilers | Department of Energy

    Boilers heat water, and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil. Steam boilers operate at a higher temperature than hot water boilers, and are inherently less efficient, but high Learn More

  • What is a Condensing Boiler and How Does it Work?

    A standard boiler gives off waste gases through a flue and into the atmosphere at a high temperature of over 200 degrees, where this is significantly reduced in a condensing boiler. The heat input is pretty much the same at about 250 to 350 degrees, but a condensing boiler has a much more efficient way of working compared to other types.Learn More
