My City Multi Pumy S was destroyed by a tree. Considering going up to the new H2 unit. My unit was 54 btu heating . The H2 is 72k. not sure of price difference yet, but figure it is probably much more. I have 54 total unit capacity in the home. Home is is CT and requires about 35k at 4 degrees. Though it might be better for resale and lower ware and tear on unit.
Thanks for any thoughts
