Whole house generators are permanently installed at your home and connect to your house’s gas line, either liquid propane (LP) from a tank installed on your property or natural gas (NG) from a utility line or custom tank. Liquid-cooled generators are best for whole house applications because these units are less likely to overheat. The advantage of liquid-cooled generators is they can operate more efficiently, without the fear of overheating in climates that regularly get above 100 degrees Fahrenheit.

Air-cooled generators will often not work as well for longer-run, whole house applications because the cooling is not as efficient-units are more likely to overheat and shut down automatically.Ī liquid-cooled generator pumps coolant through the engine block which absorbs heat from the engine before moving through a radiator where the coolant cools back off and then is cycled through again. This could be done passively by the surrounding air absorbing the heat and rising away from the generator, or this could be accomplished with “forced air cooling” which uses a fan to blow air across the generator’s engine. Liquid CooledĪn air-cooled generator uses the surrounding air to cool the engine.

NOTE: Some generators are listed by watt (W) and some by kilowatt (kW). house averages a minimum of 5,000 to 7,000 watts so many standby generators are sold with a minimum of 8,500 to 10,000 watt outputs.

You can also check with your power company or on your electric bill to find your regular power needs. You should multiply the total watts of your appliances by at least 1.5 to create an adequate margin of safety. You can also calculate this yourself by finding the wattage rating label on each of your electrical appliances. Online wattage calculators will help you find what size generator is the best fit for powering your whole house. Refrigerators, air conditioning, sump pumps, water heaters and space heaters will have some of the highest power draw in your house. When purchasing a generator, the most important determination is the power requirements of your house and especially your large-draw electric appliances.
