Reliable Power for Whole-Home Backup

The Kohler 24kW Generator + Block Heater Liquid Cooled 120/240 Volt Single Phase is capable of powering most household systems simultaneously.

Typical appliances supported include:

• Central air conditioning (up to 5 tons)
• Heating systems
• Refrigerators and freezers
• Lighting systems
• Water pumps
• Security systems
• Office equipment
• Internet routers and servers

With 24kW output on propane and 21kW on natural gas, this natural gas standby generator delivers enough power for most residential properties.

---

Dual Fuel Capability

This generator operates using either natural gas or liquid propane (LP), offering installation flexibility depending on available fuel sources.

Fuel consumption estimates:

Natural Gas:

• 301 cubic feet per hour at full load
• 199 cubic feet per hour at half load

Propane:

• 3.1 gallons per hour at full load
• 2.3 gallons per hour at half load

Using natural gas is often preferred for residential installations since it connects directly to the home gas line, eliminating the need for fuel storage.

However, propane remains an excellent option in rural areas without natural gas infrastructure.
