ROI on the SafePlug Energy Manager Kit

SafePlug Energy load controllers can pay for themselves in a year or less and then make you money in several ways:     Reduce your electricity bills Extend the life of appliances and electronics Prevent personal injuries, including shocks and burns Detect thefts of expensive electronics The payback or Return On Investment (ROI) for purchase of a SafePlug Energy Manager Kit depends on several variables: Price of electricity. The higher the price of electricity, the faster a SafePlug investment will pay for itself and actually make money. For example, if the price of electricity is $0.20/kWhr versus $0.10/kWhr, the SafePlug Energy Management equipment will pay back twice as fast. Note, with Time Of Use electricity pricing, the price of electricity may double or triple at certain times of the day to incent conservation to reduce the possibility of black-outs. Choose appliances to control. We recommend that you should avoid remote control of some appliances for safety or convenience reasons. Do not remotely control the following appliances:        Life support equipment (e.g. oxygen pump, health monitors), Safety equipment (e.g. fire alarms, smoke detectors, CO detectors, gas detectors) Food preservation appliances (e.g. refrigerators, freezers) Cooking equipment (due to hazard of fires, all cooking equipment should only be operated while attended) Computing equipment with unprotected hard drives (sudden disruption of power to a hard drive can destroy it and the data contained on it) Hand tools (normally only used manually and few have phantom power draw) Clocks (loss of accurate time) The following appliances can be controlled via SafePlug load controllers [Wording indicates that these are the only appliances that can be controlled via SafePlug, not sure of a better wording, but for consistency with the above section, maybe ‘We recommend controlling the following appliances, and others, via SafePlug load controllers.’]based on a schedule or in conjunction with activity sensors to conserve energy and save money:      Home theatre equipment (e.g. big screen TV, subwoofers, amplifiers) Window air conditioners (note: cooling appliances should not be turned on until adequate “off” time allows coolant to drain out of the radiator to avoid damage to the cooling pump) Dehumidifiers Pool pumps Space heaters

   Water heaters (requires setting temp control to high for potable water) Outdoor lighting EV charging stations Other appliances to consider for remote or scheduled control would be interior lights, office equipment, electronic games, washer, dryer, dishwasher, and fans. Set a Savings Strategy. Most people do not want to inconvenience their lifestyle to save money. However, the longer you turn off appliances, the more you will save. After selecting target appliances, prioritize the list based on money savings potential. The money saved depends on the following formula: (Appliance power draw in kW) X (Off Time in hours) X (Price of Electricity in $/kWhr) = Money Saved! The following examples demonstrate the savings possible with little inconvenience. Example 1: Window Air Conditioner. If you use a SafePlug model 1202 or 1203 duplex-receptacle to turn off a 1000W air conditioner during peak pricing time (e.g. $0.20/kWhr peak, $0.10/kWhr base) for 4 hours per day, then the savings is $0.80/day or $16/mo (assuming only turned off during week days) or $60 over a 4 month usage season. [Doesn’t the air conditioner have to run a little longer when you schedule it back on if has been off most of the day, eating into some of the savings?] Example 2: Home Theatre. If you use a SafePlug model 1202 or 1203 duplex-receptacle to disconnect power to a big screen TV, subwoofer and amplifier together that draw 100W of phantom power 24/7, the TV is not watched from midnight to 8 PM ever (20 hours/day), and the average cost of electricity during this period is $0.14/kWhr ($0.10/kWhr base rate), then you can save $0.28/day, $8.40/month, or $100 per year on your electricity bill. Example 3: Dehumidifier. If you use a SafePlug model 1202 or 1203 duplex-receptacle to disconnect power to a 350W dehumifier during peak-pricing hours and for a total of 12 hours per day, and the average cost of electricity during this period is $0.20/kWhr ($0.10/kWhr base rate), then you can save $0.84/day, $25/month, or $150 for a 6 month season on your electricity bill. [I think you probably have the savings in this scenarios doubled. My dehumidifier cycles throughout the day. If I turn it off for 12 hours and then on for 12 hours, it will run close to the same amount of time getting the water out of the air. Since I shut it off when power is $0.20/kWhr and run it when it is at $0.10/kWhr, I save $0.10/kWhr, not $0.20/kWhr] Example 4: Space Heater. If you use a SafePlug model 1202 or 1203 duplex-receptacle to disconnect power to a 1500W space heater during non-working hours and for a total of 16 hours per day, the heater is running 20% of the time, and the average cost of electricity during this period is $0.14/kWhr ($0.10/kWhr base rate), then you can save $0.67/day, $20/month, or $80 for a 4 month season on your electricity bill.

Example 5: Pool Pump. If you use a SafePlug model 1313 load controller to run your 1.5 horsepower (1100 Watts) pool pump only during off-peak hours for 6 hours per day, and the average cost of power during the other hours is $0.14/kWhr ($0.10/kWhr base rate), then you can save $2.77/day, $83/month or $250 over a 4 month pool season. Example 6: Electric Water Heater. If you use a SafePlug model 1313 load controller to run your 60 gallon electric water heater only in the evening and for bathing in the morning (estimated reduction of normal heating power-on time of 3 hours per day to 1.5 hours per day), and the average cost of power during the other hours is $0.14/kWhr ($0.10/kWhr base rate), then you can save $1.15/day, $34.50/month or $400/year. [I have a gas water heater, so I don’t know the answer to this, but this implies that an electric water heater costs $800/year to run!? My electric bill is only $1600 /year. Glad I don’t have an electric water heater.]

More Savings as Electricity Prices Increase

Although all the above examples use a base rate of $0.10/kWhr (with a peak rate of $0.20), some parts of North America actually pay $1.00/kWhr and in the rest of the world, the costs are even higher. Over the past 10 years, the cost of electricity in North America has more than doubled. Coal and natural gas resources are becoming more scarce and prices are increasing. [un-true statement, natural gas is becoming more plentiful due to fracking and the costs have been coming down over the past 10 years. Coal pricing is also coming down due to less demand (from natural gas becoming the predominant fuel for electrical plants in the US). Prices for electricity in the US may be rising soon due to Obama’s green proposals where coal plants are taxed and regulated into extinction. I would recommend replacing this last sentence with ‘Energy proposals in the US could accelerate this pricing trend.’] The table below shows the annual savings from using SafePlug to manage your energy at various electricity base rates: [Is there a clean way to indicate that the savings indicated for the Home Theater is from phantom power reduction and the rest of the chart is from time of day shifting?] Window A/C Home Theatre Dehumidifer Space Heater Pool Pump Water Heater $0.10

Saving By Extending Appliance Life All SafePlug load controllers extend the life of appliances by absorbing electrical surges and by disconnecting power to the appliance when the line voltage is too high or too low or if the appliance becomes overloaded. These days appliances are designed to be replaced, not repaired. Nevertheless

the average home has over $10,000 of appliances and electronics. Simply by extending the life of your appliances by one year, you can save $1,000.

Saving By Preventing Fires

All SafePlug receptacles are designed to help prevent fires. Electrical faults are the third largest cause of residential house fires (#1 cooking, #2 arson). Electricity can start fires in many different ways. SafePlug protects against 2 of the 3 top electrical ignition causes: #1 bad wire junctions and #3 overloaded appliances (arcing is #2). Without SafePlug, your house has little or no detection and protection from these dangers. A ten second duration fire can cause $1,000 damage (average) from smoke alone. A one-hundred second duration fire can cause $10,000 damage (average). A fire that lasts 1,000 seconds usually destroys a home (>$100,000 damage). Fire prevention with SafePlug receptacles is much better than just fire detection with a smoke alarm.

Saving By Detecting Thefts

SafePlug model 1202 and 1203 receptacles can detect and report when an appliance gets unplugged. Thefts can be identified immediately and stopped.
