Hey Everyone!
Firstly Thanks for all the help here. I recently bought a house that has an older Weil McClain Boiler, pics are below.
I recently renovated my main floor and added some radiant tubing in my kitchen. I want to add a separate zone, and also add zone control valves so I can better control my heat! I could use some advice on how to plumb things. I am an engineer, I can solder pipe and also have pex tools.
Here is my initial plan, I want to repipe the return, making sure everything is the same size. Currently it is not. I want to add Two zones, one for the radiant heat and one for future plans when we renovate our basement, currently has no heat.
Currently the first floor is one a zone with a taco circulator, that has the larger 1 inch pipe and hydronic loop with t valves going up to the baseboard. I plan to leave that alone. The second floor (apartment) is on the 1/2 inch line and its own circulator. They each have there own flow control diverters on the feed and the circulators are on the return. I believe the zone valves will help me get things running more efficiently as it seems the boiler cycles quite a bit.
As for the radiant heat, I understand I need to plumb in a mixing valve. That makes sense, but I have also read that flow diverters work better as they allow pressure to be maintained in the loop. What im unsure of is how to plumb that in, with a circulator on the return.
Any help here is really appreacted!
Thanks!
