   Vanderbilt boiler An American design, similar to the Lentz and large launch-type boilers. [36] Velox boiler: [61] vertical boiler: flued or fire-tube designs where the main shell is a cylinder on a vertical axis, rather than horizontal. Boilers of this external form may have a great variety of internal arrangements.

3. Condensing boiler - Wikipedia

   en.wikipedia.org/wiki/Condensing_boiler

   Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.

4. Electric boiler - Wikipedia

   en.wikipedia.org/wiki/Electric_boiler

   Some types of boilers aren't used for heating, but for other purposes. A boiler could be used as a household appliance or to produce steam for an industry. An electric steam boiler is intended to produce steam for process industry or other uses, such as drying, heat treating, and others. These are generally permanently installed systems with ...

5. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   The fourth category of furnace is the high-efficiency condensing gas furnace. High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. [3] A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as ...

6. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   In Sweden proposals exist to phase out direct electric heating for this reason (see oil phase-out in Sweden). Nuclear, wind, solar and hydroelectric sources reduce this factor. In contrast, hot-water central heating systems can use water heated in or close to the building using high-efficiency condensing boilers, biofuels, or district heating.
