SJG Heating Service, Inc. was founded in 1994, and has grown to service the lower Hudson Valley of New York and ten counties in New Jersey. We are a family owned and operated company whose goal is to service our customers with fast, economical service performed by factory trained professionals. Although we service all makes and models of boilers; we sell, install and service HydroTherm boilers as our specialty. Our owners have a twenty three year relationship with the HydroTherm boiler company and are "factory trained and certified" in all models both current and obsolete. Our service trucks stock a complete inventory of all HydroTherm repair parts and we use only HydroTherm "Original Equipment Manufacture" (OEM) parts so your boiler will be repaired correctly the first time, every time.

SJG Heating Service, Inc. is a "factory certified contractor" for sales, installation and service of the HydroTherm HydroPulse boiler. The HydroPulse is the most efficient gas-fired boiler available today! The HydroPulse can obtain efficiency levels as high as 97% and requires no chimney for venting. When installed with an indirect water heater the Pulse can create your domestic hot water more efficiently than any other system. Visit our FAQ and Hydropulse page for more information on the HydroPulse Boiler.

Throughout the seventies and early eighties HydroTherm marketed a "wall-hung" boiler called the Celtic. The Celtic was removed from the HydroTherm product offering in approximately 1986, yet many of these unique boilers remain in service throughout North America. SJG Heating Service, Inc. is the most experienced contractor in the service of the Celtic boiler. Visit our FAQ and Celtic page for more information on the Celtic Boiler.
