A boiler, or hydronic, heating system circulates hot water through warming baseboards, radiators and/or radiant tubing in floors or ceilings. There are many advantages to heating your home using a boiler system, whether it is for a new home or as a replacement heating system.


The Laars Customer Center is a 70 seat live-fire training facility designed specifically to educate HVAC professionals about hydronic systems and Laars' current and next generation of heating technologies. At the front of each classroom are two equipment stations that can display any Laars boiler or water heater. Flexibility in Factory Training content and techniques was the primary design driver with both the 12,800 square-foot facility and curriculum. Prestructured training course or an a la carte approach of topics can be chosen.
