I use primary / secondary piping due to this house required 5 different temps for each zone.. 4 had their own mixing valve with pump.


Definitely PS piping on a new system. Closely spaced tees, or low loss header? What kind of mixing valves did you use? Manual or electric?
Got pics?
How did you measure the piping to be cut? Did you use a folding ruler or tape measure? :chicken

I've been meaning to take a look at these - they look great.
A mixing valve with a choice of setpoint control, or outdoor reset.
What do you think?

I have a customer with one installed on a radiant zone. It works well as far as I've seen. Never personally installed one yet.
