Im building a new house with 3000 sq ft of living quarters, 1.5 story with a vaulted ceiling in the kitchen/living room area. And a 1200’ garage. I installed a radiant floor system, am planning on installing a heat exchanger in the duct work and heating my water. In a couple years I plan on building a separate 30x40 shop with either floor heat or just a heat exchanger. One of my coworkers has an Acme 335 and has had good luck with it. But I’ve read several bad reviews. I do like it’s simplicty of no electronics. I’ve also been looking at the Woodmaster 4400, it’s a couple thousand more but seems reliably. Not sure it’s big enough to do everything I want though. Any suggestions on which one to go with?
