Usage Instructions
To use the A. O. Smith heat pump storage tank:
- Select the appropriate model based on your desired storage capacity. The available models are TJVHP-250A (250 gallons), TJVHP-500A (450 gallons), TJVHP-750A (650 gallons), and TJVHP-1000A (850 gallons).
- Ensure that the tank is installed in a suitable location, following any local building codes and regulations.
- Connect the tank to your heat pump DHW system using the provided threaded openings.
- Make sure that the tank has proper anode protection to prevent corrosion.
- Verify that the tank is constructed with a heavy gauge steel jacket for durability.
- Check that the tank has a working pressure of 125 PSI.
- Inspect the glass-lined interior of the tank, which is fired to 1600°F for a molecular fusing of glass and steel.
- Ensure that the tank is fully insulated with a minimum of 5 inches thick, high-density polyurethane foam insulation, providing an insulating value of R30.
- Monitor the jacket dimensions, which can be found in the product specifications, to ensure proper fit and installation.

FEATURES
Heat pump DHW production often relies on minimal input and full utilization of off-peak periods to heat the stored water. These tanks are designed to take full advantage of these systems by reducing turbulence and providing unprecedented stratification. The proprietary stratification system employs a unique baffle that arrests water velocity into and out of the tank to prevent disruption of the stratified layers. An impressive R30 insulation value helps retain heat until it is demanded by the system. Draw down of 95% sets these tanks apart from others, delivering more hot water from a given capacity.
