Weil-McLain Boilers
Weil-McLain has been manufacturing residential boilers in the United States since 1881. Their lineup covers cast iron oil and gas boilers built for long service life as well as modern high-efficiency condensing models that meet today's tightest efficiency standards. For Southern NH homes replacing an older boiler, a Weil-McLain unit offers a strong balance of reliability, parts availability, and value.
Our technicians are factory-trained and certified on all three major oil burners, Carlin, Beckett, and Riello, so we can match the right burner to your equipment and fine-tune it for optimal efficiency.
