  • Thermosiphon - Wikipedia

    Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces.Get Price

  • Heat Pump vs Furnace Calculator for Natural Gas

    Jul 14, 2021 · Even if a boiler or furnace is efficient at turning gas into heat, it still produces nearly as much CO 2 as any less efficient boiler or furnace. That's because you can't produce heat from natural gas without producing CO 2. The efficiency of a boiler or furnace describes how much heat energy is released from the natural gas.Get Price
