in THE MAIN WALL
Can a Viessmann Viodens condensing wall boiler be used to supply hot water for air handlers for hydro air. I don't seem to be making hot enough water. Thanks for any help.

    Yes

    Do it all the time. Are we not making or are we not delivering enogh gpm to the airnhandler. More info please. Which Vitodens? What size air handlers? What is the heat loss of each a/h zone? What size pipe to the a/h's? What pump are you using for the a/h?



    Are we using a low loss header on the boiler? Are you running a 1.6 slope? If a 200 did we get the boiler out of nightine setback? Could ask dozens of questions.
