Lochinvar SQUIRE SIT065 65-Gallon Indirect Water Heater Review
The Lochinvar SQUIRE SIT065 is a 65-gallon indirect water heater designed to pair with Lochinvar boilers. Indirect water heaters use external boiler heat rather than integral combustion or electric elements — common in hydronic-equipped homes.
Specs: 65 gallons stored, internal stainless steel coil heat exchanger, polyurethane foam insulation. Compatible with Lochinvar boilers and most US residential boilers (oil, gas, propane). 10-year tank warranty.
The 65-gallon capacity covers 4-5 person households with heavy demand. Sits between the smaller SIT040 (40-gallon) and larger SIT080 (80-gallon) in Lochinvar's SQUIRE indirect line.
The Lochinvar engineering: more robust internal coil than competing brands (Amtrol BoilerMate, HTP SuperStor), better insulation reducing standby losses, longer warranty.
About $1,800 unit, $2,800-$3,500 installed depending on boiler integration. Right buyer: home with existing or new Lochinvar boiler, 4-5 person household demand for hydronic-driven DHW.
