LRS-STOR SRIS Indirect Water Heaters
LRS-STOR SRIS Indirect Water Heaters Laars Heating Systems offers high volume single-wall and double-wall indirect water heaters. ll model types feature a super-efficient heat exchanger a carbon steel, glass-lined coil for the Laars-Stor Single Wall and a stainless steel coil for the Laars-Stor SS. The Laars-Stor2 features a new double-wall heat exchanger. The new design is super-efficient and is the perfect mate for your boiler, heat pump or solar heating system. Laars Heating Systems single-wall and double-wall indirect models are dependable and durable water heaters that supply an unprecedented volume of hot water. They are built to last, problem-free, efficient and offer high deliverability for years. That s why all residential Laars-Stor and Laars-Stor2 Series indirect water heaters offer a Limited Lifetime Tank and Heat xchanger Warranty. When homes already have an existing boiler system, Laars single-wall and doublewall indirect water heaters are the perfect complement.
IMPORTNT RSONS TO ONSIR LRS-STOR SRIS INIRT WTR HTR SV MONY N NRY Indirect water heaters use the home s boiler, heat pump or solar heating system as the heat source. They are usually the least expensive way to provide hot water. HIH PRORMN Laars-Stor models feature an extremely efficient heat exchanger made of a glass-lined carbon steel tubing giving an exceptional first hour delivery and high volumes of hot water. LOW PRSSUR ROP Laars-Stor Series indirect water heaters were designed to minimize pressure drop so that customers get the hot water they want at the pressure they have come to expect. IINY Since hot water is stored in the water heaters insulated storage tank, the boiler, heat pump or solar heating system does not have to turn on and off as frequently, improving its fuel economy. INSTLLTION S These water heaters require no fuel or venting materials. They connect directly to an existing boiler. LIMIT LITIM WRRNTY Laars-Stor models were designed and built for problem free and reliable service. We offer this warranty because of our confidence in the dependability and durability of the product.
