About Us - Company History

In 1948, engineer Avy Miller formed Laars Engineering as a company 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 domestic hot 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. Today, Laars is a member of the Bradford White family of companies and is headquartered in Rochester NH, USA where all design, testing and manufacturing of Laars products occurs. We take pride in our Made in America products and have invested in our facilities and processes to make sure only quality products are shipped to you.

-  Laars engineers use the latest in fluid flow and heat transfer simulations as well as extensive lab testing when developing new products to ensure proper operation of your new heating system.

-  Manufacturing 'live fires' each and every heater that leaves our facility to conduct needed safety checks and functional tests. We record the boilers performance during this process to ensure quality is met. Not all manufactures do these extra functional tests for their customers.

-  We believe having advanced training available for those that install and service our products is very important. To support this we have recently built a new, state of the art training facility where our boilers can be live fired in a ‘hands-on’ learning environment. Visiting contractors and engineers train with LAARS applications experts and our engineering teams. Learn more about our training here

-  Laars products are widely used in space heating, radiant floor heating, volume water heating and industrial process markets covering a range of 50,000 to 5,000,000 BTU's, utilizing either natural gas or liquid propane fuels. LAARS meets the needs of today's more demanding heating systems applications with over 20 different heating products and supporting accessories and controls. For your home, business or commercial heating needs Laars products are the quality choice.
