Does this boiler alleviate the need for an external zone valve/circulator pump controller? All of the thermostats wire directly into the boiler for each discrete zone?

[@JimSperanza]

Correct! Up to 3 zones can be controlled. You can choose between 3 individual circulators or a single circulator with 3 zone valves.

Great work! Curious why you don't use Webstone press rotator isolation flanges instead of the threaded Taco? How does the rod hold up when the panel is vertical and the system full of water. I've always used strut, the biggest problem being you have to work your layout in a single plane, not always easiily done! I see you use mixing valves alot, ever tried a mixing bridge? The Taco VT 2218 you like to use would be awesome for that application.

[@JimSperanza]

I do use them time to time but mainly because the Taco flanges have a large end where I can support the pumps by using a conduit clamp.

How much is cost

[@abacojack13]

can I see a build using the thermostat terminal block install? also, have you done a build where the customer can use wireless thermostats?
