Laars ls-ss-75-l Indirect Water Heater 73 Gallon

Product Description

The LAARS ls-ss-75-l is a 73-gallon stainless steel single-wall indirect water heater designed for hydronic heating systems. It operates as a storage-style indirect water heater, drawing heat from a boiler loop rather than a direct-fired burner. The stainless steel tank construction resists corrosion in demanding water conditions. Licensed plumbers and hydronic system contractors are the primary installers of this unit in both residential and light commercial applications.

The ls-ss-75-l fits into hydronic system configurations where a boiler serves as the heat source. It is suited for residential homes and small commercial buildings that require reliable domestic hot water production through an indirect-fired arrangement. The 73-gallon capacity supports higher-demand hot water loads, making it a practical choice where storage volume is a priority alongside boiler-integrated heating.

Installation Notes

Installation should be performed by a licensed plumber familiar with hydronic system piping and indirect water heater connections. Shut off and depressurize the boiler loop before making supply and return connections to the heat exchanger. Follow all applicable local plumbing codes and manufacturer guidelines for pressure relief valve sizing and installation. A properly rated temperature and pressure relief valve must be installed per code requirements before placing the unit in service.
