3 OMPNY HISTORY In 94, engineer vy Miller formed Laars ngineering as a company dedicated the concept of heating water quickly by passing the 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 nine times faster than through cast iron vessels. Miller designed specialized manufacturing techniques support this new concept, and the low-mass technology found a warm reception in the U.S. market. irst applied the swimming pool heater market that emerged rapidly in alifornia after WWII, the heat exchanger designs that Laars developed also proved work well with space-heating boilers and hot water boilers. fter all, if a Laars heat exchanger could work well with swimming pool water with all of the chemicals and impurities, it could 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. y controlling flow rates, lime and scale were prevented from forming on tube walls, thereby keeping the heat transfer process clean and efficient. Today, Laars Heating Systems operates as a subsidiary of the radford White orporation with manufacturing in Rochester, NH and a distribution center in Haln Hills, Ontario, anada. Laars serves a diverse base of cusmers located in many countries all over the globe, and Laars product lines have expanded over the years cover the large range from 0,000,000,000 TU s. Laars residential and commercial products serve the hydronic, radiant floor heating, volume water heating, and industrial process markets with over 0 different product lines and many accessories and controls support these primary lines ONLIN TOOLS lectronic Literature ownloads Sales rochures Installation/Operating Manuals User s Manuals Specification Sheets Submittal ocuments Technical iscussions Warranty Sheets Master Spec ocuments Printed Literature Ordering Printed literature can be ordered easily online at Volume Heater Sizing Product Videos Properly size and specify Laars Volume Heaters via the online Laars sizing ol!

Maintains user chosen temperature rise between boiler inlet and outlet. Operates in degrees, ahrenheit or elsius, user selectable. User selectable elta T settings. Protective enclosure. Proprietary oiler System lgorithm: Vari-Prime will operate the boiler pump at maximum flow during boiler startup ensure stable operation is reached before introducing variable water flow. This key feature keeps the boiler s combustion and variable speed pump s flow in phase with each other, protecting the heat exchanger from potential low flow conditions. omes standard on the Laars MagnaTherm condensing modulating boilers vailable as an optional package on the Laars NeoTherm condensing boiler line. In conjunction with a variable speed pump, Vari-Prime installation will track the heating profile curve and dramatically reduce the electrical usage of the boiler pump. Vari-Prime control logic operates in tandem with Laars modulating boiler combustion controls and the variable speed pumps and drivers that are available on the market day. ased on day s energy costs vs. the cost of installing a variable speed pump system can provide an expected payback within one two years, depending on size of system, heating profile, and regional energy costs.

51 HYRULI SPRTORS 97 The Laars Hydraulic Separar tank is designed help reduce short cycling of a boiler system and separate building and boiler circulation. The Laars Hydraulic Separar uses sred boiler water buffer the system load when the boiler is producing more TU s than what the building can handle. When the building has a minimal demand, it pulls from the tank allowing the boiler rest. The Hydraulic Separar is piped so the building flow is separate from the boiler flow, allowing independent circulation. Standard: SM Sec.
