Munchkin vs. Weil McLain PhD

I've been installing Munchkin with Vision 1. I'm being told by a supplier that I should not use the Munchkin as it is not ASME rated. He recommends Peerless or Weil McLain PhD. Peerless cannot use Vision 1 and must use Tekmar for outdoor reset. WMc has outdoor reset standard and can hanle four zones without extra relays. (It has a Tekmar control on board). Munchkin Vision 1 piping is expensive and time consuming. WMc has an aluminum heat exchanger and rubber seals.

Has anyone used both boilers? How does install time compare? Venting requirements? Operation? Programming? Reliability? Tech Support? Customer Satisfaction? Warranties?


  • Munchkins can be purchased ASME

    You'll pay more, but if you gotta have it, you gotta have it...

    I installed 3 ASME 199's last year that knocked the living snot out of the gas bill for a 13 story apartment complex we retrofitted.
