Start of my boiler room

Now everyone be easy, remember I'm just a simple sales engineer. Munchkin T80, taco Outdoor reset I-Valves, going to run constant circulation, indoor feedback as hi limit. I'll keep progress pics coming.

Careful

I did the same thing when I piped my first Munchkin and it got me into a lot of trouble.

If you don't pipe primary-secondary, the boiler won't see proper flow; you will hear the Munchkin kettle on shoulder days eventually causing damage to the boiler.

Looks like you have 3 zones; 2 zones with different reset ratios and the third zone either radiators or an indirect water heater.

After you take it all apart and put it back together again, make sure the pump is on the return on your primary piping to appease the pressure switch on the boiler.

John Siegenthaler made it all very easy when he drew the diagrams that were included in the Vision I instructions for the Munchkin boiler. Even though you didn't use the Vision I outdoor reset system, get yourself a copy of the brochure that will show proper piping.

Not Real sure

What your definition of Primary Secondary is, or maybe it isn't clear in the picture (darn picture phones), but here is a drawing of what I'm doing. I plan on using a vision 1 for my indirect, the I valves control my two lowest temp zones ( basement and hard surface staple up), the third zone will be carpet staple up controlled by the boiler outdoor reset control. As for the drawings you refer to, I tend to like this type of layout for my designs.

I like to layout my piping with my primary pump pumping away, never have had pressure switch issues, yet.

Thanks for your feedback.

Had a look...

...your diagram does not seem to indicate primary-secondary piping. Several pumps are missing... Have a look over at the library, or better yet, buy Dan Holohans Book on the subject.

Plus, Dan has published a number of interesting e-Booklets and other books on heating with water, steam, etc. I'd go through the list and continue once you've informed yourself about your options. I simply fear that the current install will make the Munchkin very unhappy.

Looks like primary secondary PUMPING. But it should have pumps on each zone instead of the power heads(I cant tell in the diagram if they are power heads).
