I’m building a 30x48 cottage on my farm for my mother to live out her golden years in. It will be a Morton building so slab on grade. I’m in Southeastern Minnesota. I’m starting to put together the HVAC plan, and it will have in floor heat, but I will probably have a water coil too for a little forced air heat. She won’t need allot of domestic hot water, and I would guess the building heat requirements would be around 50k BTU max. There are allot of tankless boiler/water heater combos out there. I’m in the HVAC controls business and Lochinvar is definitely a brand that I’m familiar working with. Would the Noble be a good choice?
