Experience high-volume domestic hot water production by pairing your existing hydronic boiler with the Lochinvar SIT119 Squire indirect water heater. This 113-gallon capacity unit, identified by MPN SIT119, leverages the high heat output of your boiler to provide a rapid recovery rate for demanding households and light commercial facilities.
The system functions by circulating boiler water through an internal heat exchanger coil, which transfers thermal energy into the stored domestic water. Because it utilizes the high-efficiency heat source already present in your mechanical room, this stainless steel tank ensures long-lasting corrosion resistance and consistent temperature delivery without the need for a dedicated burner.
Key System Performance Baselines:
- First Hour Recovery: 459 gallons for high-demand applications.
- Storage Capacity: 113-gallon tank ensures ample reserve volume.
- Heat Input: Rated for up to 200,000 BTU input from a compatible boiler.
- Flow Capability: Sustained output of 14 gallons per minute.
⚠️ Application Profile: Engineered for residential properties with large luxury bathrooms, multi-family housing units, and light commercial buildings requiring high-recovery domestic hot water solutions.
