GE Profile PTWN6250M / PTWN6250MWT HydroWave Infusor washer
Estimating washer running cost from the EnergyGuide
The EnergyGuide is useful as a historical comparison, provided its test assumptions stay attached to the cost figures.
Read the label as a dated estimate
The federal EnergyGuide for GE model PTWN6250M0WT declares 160 kWh of annual electricity use and estimated yearly operating costs of $17 with an electric water heater and $12 with a natural-gas water heater. It bases the estimates on eight wash loads per week and 2007 national-average prices: 10.65 cents per kWh electricity and $1.218 per therm natural gas. The label says actual cost depends on utility rates and use.
The specification sheet is headed PTWN6250M and lists PTWN6250MWT as the white model; the EnergyGuide prints PTWN6250M0WT. Keep the zero in the label’s model code when citing its 160-kWh declaration, and do not assume that one label figure applies to every suffix or revision. The GE documents identify related model strings, but a parts or serial lookup should use the rating plate and GE’s model-specific tools.
Update the electricity component transparently
To estimate electricity at your present tariff, multiply 160 kWh by your utility’s per-kWh rate. At a hypothetical rate of 30 cents/kWh, for example, the label’s annual electricity quantity would imply $48 for electricity. That arithmetic updates only the electricity component and assumes the same annual consumption as the historical label. It does not update hot-water cost, household use, or the label’s test assumptions. Replace the hypothetical rate with the rate on your bill.
For a different number of loads, a rough proportional estimate can be made by multiplying 160 kWh by actual weekly loads divided by eight, but this remains a rough estimate: the label’s tested cycle mix and your load temperatures may differ. Keep the assumptions beside the result so it is not mistaken for a measured bill.
Account for water heating separately
The EnergyGuide reports $17 using an electric water heater and $12 using natural gas, a five-dollar difference under its 2007 assumptions. It does not publish a separate hot-water volume in the supplied label text, so do not reverse-engineer a gallons-per-cycle figure from the cost difference. Your water-heating cost depends on the household heater’s efficiency, local fuel prices, temperature selection, and how much hot water the washer uses in your actual pattern.
The washer’s installation sheet says hot water at the washer should be 120–150°F when hot wash is selected. Do not lower the household heater below safe domestic requirements simply to match a washer estimate. If hot washes are unexpectedly expensive, check the utility bill and your household water-heating setup; the supplied label cannot identify which appliance uses the gas or electricity.
Compare models on equal assumptions
The EnergyGuide’s similar-model range is shown for standard-capacity washers and is a historical comparison, not a current market price range. Compare another washer’s label by annual kWh, water-heater fuel assumption, loads per week, capacity basis, and label year. The PTWN6250M spec sheet lists a 3.6 DOE-cubic-foot capacity and 700 RPM spin; a capacity number from a different measurement convention should not be treated as directly equal without checking its definition.
Use current local rates and your own load count for a household estimate, then compare the potential savings with the purchase and installation costs of another appliance. No supplied source establishes a current tariff, current appliance price, or guaranteed savings from replacement.
