  1. If its stuck closed you don't get any heat . If stuck open then steam gets into condensate line and lowers efficiency

  2. The best way to determine is by taking temperature of the condensate piping . It should be less than 212 as that would mean steam .

  3. @Desktopia is controlled the same way . By control valves . Since steam moves by pressure rather than flow turning off a boiler means no heat in short order . This also means you can take pipes apart without draining any water

  4. Where would they be running 25lb steam for heating ?

  5. The float type also contains a thermostatic element. These are used of main piping for larger condensate volumes

  6. Basically supplying somewhere in the area of 16c of air from Air handling unit then air is reheated at the vav box and if cooling is required then valves closes of flow of water in the coil and the space receives only the cooler air from the air handling unit . Some vavs have dampers that can adjust air flow based on co2 or occupancy

  7. The difference is just the parts that need to be changed. No circulation pumps in steam to work on or fail .

  8.  @dadillen5902  these systems were popular even in 1950s . I work on these systems on semi regular basis . Dealing with steam traps and vacuum pumps etc
