Remote location of Vitodens

Jeffrey Campbell

I have a new home with no options for venting the Vitodens boiler in the designated mechanical room. The contractor , homeowner and I have chosen a remote location to put just the boiler for easy venting. Now I am wondering about the 50' to run not only the boiler suppply/return lines, but also the DHW. My design program shows with 3/4" insultion the heatloss is very little. I am just wondering if I should push to have the in-direct tank to be installed next to the boiler. Or show I just install it with the rest of the mechanical system.
What do you think?

Place the indirect within 10 feet of the Vitodens for best results. Make sure you use 1" piping to the coils, even though the Vitodens has 3/4" tappings. Without adequate flow rate to the indirect, the Vitodens can hiccup, causing an annoying service call.

Try to get the tank

next to the boiler. The pump has only so much flow and head pressure.

I am going to try to push to move the indirect, but I am not sure I can. I am using a 11-44 unit so the pumps will be external. If i size them correctly (1 1/4")and insulate the lines, can the this work well. Thanks Jeffrey
