A different post has me considering something for spring. I have two buildings that are heated by the Garn using its non-pressurized storage (no additional exchangers). One building, the workshop in which the Garn is housed, is using radiant slab while one of the buildings is a home with a water-air exchanger in the plenum. My home has hydronic heat, with a flat-plate heat exchanger because it is a pressurized system so I needed an interface hence the FP. Could I run my house as a non-pressurized system (essentially removing the flat-plate) and if so what things should I consider before doing this, or should I abandon doing this? I understand that my existing boiler could not be used as a backup. It hasn't run since I hooked up the Garn anyway. I would want to make provisions to fairly easily re-hook up the existing fossil boiler (return the home to a pressurized system) if the need should arise. I also understand that purging/cleaning the existing water in the pressurized system would need to be done prior to this as well. What else?
