    I'm currently installing a 150,000 btu weil mclain direct vent hot water boiler properly sized for the home per heat loss....home will have indirect heater with priority....6 baseboard zones using zone valves...and five radiant heating circuits...each circuit holds 5 loops piped reverse is NO object on this job....customer would like a outdoor reset control by tekmar....I just want some recommendations on what to use...radiant is not piped injection pumping can be used....and boiler would be piped primary secondary....maybe using more than one boiler and stage them? Any advice would be appreciated thank you Paul S

    Does the boiler modulate?

    Tekmar has a coup;e of options that will manage two mix temps, which I believe is what you are looking for?

    Boiler is a direct vent 80% boiler...but I was think about two 75000 btu boilers and stage them...what do you mean by modulate....?....mod-con? Paul s

    was what I was thinking.  If Budget is not an issue, install a Viessmann B2HA and skip the outboard controls.  It can manage two mixing valves and three separate ODR curves with the onboard controls.
