Vitodens theory

kf_2 Member Posts: 118

A little while back we did a Vitodens that was strictly used for heating an indoor pool. We pumped through a Triangle Tube Maxi-Flo heat exchanger. We installed a Brass well on the return line between the pool and the pool pump and inserted the #5 sensor that is usually installed in the well of the indirect water heater. We then set the Domestic Hot Water temp on the Vitodens Comfortrol to 85 degrees. It works absolutley fabulous.

And it is a perfect application for a condensing boiler.

    Vitodens theory

    As I was chatting with a customer re his newly installed vitodens and how his dhw is setup - this thought raced through my head - "can the dhw output of this boiler be used for other heating applications??" I'm sure I had a bit of a dazed look while I pondered this (my customer was looking at me as if I had been away!)
    If the dhw output is not needed for dhw production could it be used for high temp baseboard? or a spa heater etc??? or???
    This is such a great boiler - has anyone had time to think outside of the viessmann box?? and use the boiler for other applications???

    Your reply is exactly where my thinking was going - and I must wonder out loud if this sort of heating load would then comprimise the primary heating application - eventhough your install was pool only. I think that as time proves the vitodens to be a superior boiler - hybrid systems will emerge. I can hardly wait ....

    \"extra\" capacity?

    If you're thinking the DHW output provides access to some excess unused capacity, I don't think that is the case.
