Residential Boilers

SRGI offers the broadest array of hydronic heating systems in New England and Upstate New York. Whether you need the traditional reliability of American made Cast Iron oil or gas boilers, or the latest high efficiency boiler systems, or even the latest electric boiler options, we have the experience and support necessary to help you make educated choices.

Traditional Cast Iron Products

Cast Iron Boilers are known throughout North America for their rugged reliability, operating efficiencies and longevity. Our products range from small residential boilers to the largest cast iron commercial boilers available in North America. Typical applications range from homes and apartments up to very large institutional buildings such as schools, universities and government buildings.

Cast Iron boilers can provide long term trouble free service in burning oil, natural gas, or propane. They can integrate with either hot water or steam system. 

High Efficiency Low Mass Gas Boilers and Combi Boilers 

The fastest growing segment in hydronics today is high efficiency modulating water boilers. Based on technology first used in Europe and the Far East, these products a generally light weight, space saving, and utilize advances control and operating systems.

Light weight and compact – these systems do not require traditional utility space. Rather, their modern styling and extremely quiet operation allows them to be installed in many applications that would simply not be possible with a traditional boiler.

Highly efficient modulating operation provides unparalleled comfort regardless of current weather conditions.

Flexible venting systems do not require traditional chimney systems and can accommodate either vertical or horizontal vent terminations. Many boilers are sealed combustion which draw combustion air from outdoors to improve safety and efficiency.

Domestic hot water is often produced on demand by these boilers saving both space and energy cost. 

Magnetic Filter and Chemical Technology to protect any Hydronic Heating System

The number one killer of hydronic heating systems is iron oxide sludge. It is caused by the oxidation of metals within a system and can harm pumps, heat exchangers, expansion tanks, and valves. Don’t buy another boiler without protecting it with a magnetic filter first.
