in THE MAIN WALL
Spec'd an Ultra for a job with radiant slabs. Installed slab sensors, would like to use new WM Ultra boiler. Was recently offered a Munchkin 140 at a great price. Not sure which boiler to pick. The Ultra is new, would have to disable control to use with Tekmar, or I could use the Munchkin with the 371 and the 369 and not worry about new technology. Any ideas?

    Tekmar controls with boiler

    Andy, here in Fairbanks we don't have access to either the Ultra or the munchkin, very little gas here. However, instead of using the 371, have you thought of using the 363? Its digital, will accept the zone input from the 371, will do both boiler and system reset via VSI or mixing valve, and gives DHW priority. Plus, its about $225 cheaper here in my neck of the woods. As long as you have to use a 369 anyway...might look at the 363. Sorry I can't help with the boiler question,
    Happy Heating
