I was recently told that my limited supply of hot water was because cold water was mixing in with my hot water supply. On a household aquatherm heating system (gas hot water heater) is there a valve that could be stuck or is there a pump that may not be working?
You may want to post this as your own thread- it may get lost when tagged to this one (being on a similar but different subject). You will get more visibility that way! (And probably the right answer, too.)
out of Largo Florida has a pretty complete line, vertical, horizontal, direct and belt drive, DX coils, water coils, options for stainless steel casings and drain pains. Other features abound also. Variable speed too.
While somewhat commercial/institutional in focus, their fan coil unit line, especially the CDV and CDH models work well in quality housing.
