Product FAQ

What fuel type does the Bosch Therm 830 ES part number 7703411074 require?

The Bosch Therm 830 ES part number 7703411074 is configured exclusively for liquid propane fuel. It is not compatible with natural gas without a conversion process and is not field-convertible in a standard installation. Customers requiring a natural gas configuration should select the Bosch Therm 830 ES NG model, also available at RuralEnergy.com.

What hot water flow rates does the Bosch Therm 830 ES LP deliver?

The Therm 830 ES LP delivers 8.3 gallons per minute at a 35°F temperature rise and 5.3 gallons per minute at a 55°F temperature rise. The minimum activation flow rate is 0.5 gallons per minute, meaning the unit will begin firing once water flow reaches that threshold. These flow rates make the unit well suited for whole-house residential hot water demand in moderate to high-use households.

Can the Bosch Therm 830 ES LP be installed outdoors?

The Therm 830 ES LP supports both indoor and outdoor installation configurations. Outdoor installation requires a separately purchased outdoor installation kit, which is not included with the unit. Indoor installation uses stainless steel venting components with a maximum total vent run of 61.25 feet. The specific installation configuration — indoor or outdoor — should be determined prior to ordering so that the appropriate venting or outdoor kit components can be sourced.

What does intelligent cascading mean for the Bosch Therm 830 ES LP?

Intelligent cascading allows multiple Therm 830 ES LP units to be linked together in a single hot water system to serve larger hot water demand loads than a single unit can supply. When cascaded, the units communicate with each other and distribute the hot water demand load across the group, rotating the lead unit to balance wear over time. This capability makes the Therm 830 ES LP suitable for larger residential applications or light commercial installations with elevated hot water demand.

What water pressure requirements must be met for the Therm 830 ES LP?

The Bosch Therm 830 ES LP requires a minimum water supply pressure of 30 psi and is rated for a maximum operating water pressure of 150 psi. Water supply pressure below 30 psi may prevent the unit from firing or maintaining consistent output temperature. Water pressure exceeding 150 psi can damage internal components and must be reduced with a pressure reducing valve installed upstream of the unit prior to connection.

Can the Bosch TSTAT2 wireless remote be used with the Therm 830 ES LP?

The Bosch TSTAT2 ProTankless Wireless Remote is compatible with the Therm 830 ES LP and is available separately at RuralEnergy.com. The TSTAT2 allows the user to adjust the output temperature setting of the heater wirelessly from any room in the home within the unit's 100 to 140°F operating temperature range. Installation requires inserting the TSTAT2 receiver circuit board into the Therm 830 ES LP control panel and connecting it to the motherboard using the included connector wire.
