Comparing Commercial Boilers to Residential Boilers

[sandra]

There are people that believe if you purchase something designed for commercial use you will be getting a higher quality product, but the truth is the quality of commercial boilers and residential systems is the same. The difference between the two systems is the size of the units.

I would like to replace one huge bioler that is not efficient with something that is resonable. Old one had 3 leggs, one per floor and I hopped to replace one leg at he time and leaving old one (huge one) as is and where it is. Old one is 7 ft tall, 10 or more long and at least 5 ft wide. Any ideas?
