I could use some help in my search for a boiler (with storage) to install in my basement. My first thoughts are for a unit with no smoke spillage on refills, easy cleaning & maintenance and minimal noise. There is also the need for a solid unit with available parts, warranty, longevity, etc... My only access to the basement is a 3' man door with 4 steps into the basement. The house is very air tight (ICF) 2000 sq ft main floor, 2000 basement, both with in floor heat, and an attached two car garage where I plan to put a modine heater loop from the house system. Thanks in advance for your suggestions on boilers or anything I might be overlooking.
