tekmar

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 return....money 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 yet...so 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
