I need to replace an 45 year old American Standard boiler for our hot water heat system. It's a 75k with 60k output. It has a closed type expansion tank, single zone. I bought a used HE II Boiler, 100k with 82k output. Will I be able to use the old expansion tank? I'm pretty good with things but is this a huge job?
