Electric Furnace Generator Size Calculator

Estimate the recommended generator size in kilowatts for running an electric furnace based on furnace heating capacity, blower motor size, heating element efficiency factor, and desired startup safety margin. The calculation converts furnace BTU input to electrical demand, adds blower load, and applies extra capacity for startup and continuous operation.

Well Pump Generator Size Calculator

Estimate the recommended generator size for starting and running a well pump based on pump horsepower, pump voltage, motor type, starting method, and system efficiency margin. The calculator returns the suggested generator wattage needed to handle motor starting surge and continuous operation.

Freezer Generator Size Calculator

Estimate the recommended generator running wattage for a freezer by accounting for freezer size, freezer type, compressor efficiency, starting surge, and additional headroom for reliable startup and operation.

Appliance Load Calculator for Generator

Estimate the recommended generator size in watts based on the combined running load of appliances, added startup surge capacity, desired safety margin, and whether the generator is intended for continuous or occasional backup use.

Backup Generator Size Calculator

Estimate the recommended backup generator size in kilowatts based on essential running load, starting surge, fuel type efficiency, desired safety margin, and whether the system is for whole-home or essential-circuits coverage.

Standby Generator Size Calculator

Estimate the recommended standby generator size in kilowatts based on total running load, largest motor starting surge, desired safety margin, fuel type efficiency factor, and whether central air conditioning is included.
