Ratings & Reviews

SGO Oil Boiler is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Still working fine at 14+ year Bought this house in 2003 with a Weil McClain A/B SGO 4 that was already a few years old, Still working fine, no problems with the boiler. One time a few years back the Riello burner acted up, but the service tech for our Oil company was able to get it going no charge under our 24/7 service contract
