Burner Depot carries a full line of replacement parts for Teledyne-Laars brand boilers and hot water heaters. Laars designs, tests and manufactures high efficiency residential and commercial hydronic boilers, volume water heaters and commercial pool heaters. 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. 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.
