LAARS Heating Systems

Laars is an American company with its manufacturing facilities located in the United States of America, and is headquartered in Rochester, NH, USA. Products made by Laars are manufactured in the United States using the finest raw materials and components from around the world to deliver the highest quality and value to its customers. Laars has a rich history of product development within the heating industry, starting in 1948 when engineer Avy Miller formed Laars Engineering. Laars Engineering was dedicated to the concept of heating water quickly by passing water through finned copper tube heat exchangers. Miller realized that moving water at high velocity through "low-mass" heat exchangers such as finned copper tubing could heat water up to nine times faster than through cast iron vessels. Miller designed specialized manufacturing techniques to support this new concept, and the "low-mass" technology found a warm reception in the U.S. market. First applied to the swimming pool heater market that emerged rapidly in California after WWII, the heat exchanger designs that Laars developed also proved to work well with space-heating boilers and hot water boilers. After all, if a Laars heat exchanger could work well with swimming pool water which uses chemicals and contains impurities, it would work even better with clean water and closed loop hydronic systems. The Laars heat exchangers with their higher velocity water flow also solved another problem - that of scale build-up in the tubes. By controlling flow rates, lime and scale were prevented from forming on tube walls, thereby keeping the heat transfer process clean and efficient. Laars- break-through designs continued over the years and the company grew.
