I recently had some questions answered on this site about the Weil Mclain Ultra boilers. Well I need a little more help knowing I shouldn't be doing something different.
I have a 1970 house, in Minnesota (cold winters), 2900 square feet, multi level. I have 5 levels total. Currently have baseboard heat combined with 1 room with electric cove. My current plan was to put in a WM Ultra boiler (my HVAC guy suggested an Ultra 105). I currenlty have 120' Baseboard, and will be adding another 40 feet or so to replace the elecric cove and a add to room we are finishing in the basement.
Should we be doing a heat loss or just sizing based on the amount of baseboard I currently have and the feet that I am adding, and assuming that since it worked in the past it will work going forward.
Should I be putting in an electric boiler, or a dual fuel system with a less efficient (and less costly) LP boiler, or just try to get a very efficient boiler like the ultra?
Any thought on this...
