2. Condensate pump - Wikipedia

   en.wikipedia.org/wiki/Condensate_pump

   A condensate pump is a specific type of pump used to pump the condensate produced in an HVAC (heating or cooling), refrigeration, condensing boiler furnace, or steam system. [ 1 ] Applications

3. 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 ...

4. Central heating - Wikipedia

   65–97% for gas-fired heating; 80–89% for oil-fired and; 45–60% for coal-fired heating. [26] Oil storage tanks, especially underground storage tanks, can also impact the environment. Even if a building's heating system was converted from oil long ago, oil may still be impacting the environment by contaminating soil and groundwater.

5. Comparison of pumps - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_pumps

   Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

6. Gas–oil separation plant - Wikipedia

   en.wikipedia.org/wiki/Gas–oil_separation_plant

   For a full description of such a plant, see Oil production plant. [3] A gas–oil–and–water separator is called a 3-phase separator. [4] The gas and oil or condensate are pumped through designated pipelines, while the sand and other solids are washed from the separator and disposed of overboard.

7. Hydronics - Wikipedia

   en.wikipedia.org/wiki/Hydronics

   In two-pipe steam systems, there is a return path for the condensate and it may involve pumps as well as gravity-induced flow. The flow of steam to individual radiators can be modulated using manual or automatic valves.
