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.
Natural-gas (or bio-gas) condensing boilers and hot-air furnaces increase efficiency over standard hot-flue models. Standard electric boilers can be made to run only at hours of the day when they are needed by means of a time switch. [35] This decreases energy use vastly. In showers, a semi-closed-loop system could be used.
The International Energy Agency has said that new gas boilers (or gas furnaces) should be banned no later than 2025. [2] Many installations and appliances have a life-span of 25 years, leading for calls that the bans must take place immediately, or at latest by 2025, because otherwise targets of net zero by 2050 cannot or are unlikely to be ...

The US economy is already set to lower its energy and carbon intensity, but explicit policies will be necessary to meet climate goals. These policies include: a carbon tax , mandated standards for more efficient appliances, buildings and vehicles, and subsidies or reductions in the upfront costs of new more energy-efficient equipment.
Rosenfeld’s main motivation for improving energy efficiency was to save money as well as save resources such as oil, gas, and forests for future generations. [16] The purpose behind the Rosenfeld effect was not only to set an example in high efficiency standards, but also to curb the threat of carbon-emissions which lead to greenhouse gases ...
