This fresh Williamson 3-section oil-fired hydronic boiler paired with a new 40-gallon Bradford White indirect-fired water heater is a huge upgrade compared to the outdated system we removed. With a new burner, priority hot water zoning, and upgraded controls, this system will keep the family comfortable all season long—while finally providing reliable and consistent hot water they can count on. Another quality install by A.H.S. – Your Mechanical Contractor. #advancedheatingservicesinc #ahs #boil
