Heat Pump vs Furnace Cost Calculator
TL;DR: Heat Pump 1,500W × 8h = 12.00 kWh/day = $1.92/day, $57.60/month, $691.20/year at $0.16/kWh — 公式 ▸
kWh = watts ÷ 1000 × hours
cost = kWh × rate per kWh
1500 ÷ 1000 × 8 = 12.000 kWh/day
12.000 × 0.16 = $1.92/day| Period | Energy | Cost |
|---|---|---|
| Per hour | 1.500 kWh | $0.24 |
| Per day | 12.00 kWh | $1.92 |
| Per month (30 days) | 360.0 kWh | $57.60 |

How this cost is calculated
The formula is kWh = watts ÷ 1000 × hours, then cost = kWh × your rate per kWh. Standing charges and tiered or time-of-use pricing are billed separately by your supplier, so treat these numbers as the marginal cost of running this appliance rather than a full bill.

Frequently asked questions
How much does a heat pump cost per hour?
A 1,500W heat pump costs about $0.24 per hour at $0.16/kWh.
Is a heat pump cheaper than resistance heating?
Usually yes because it can move two to four units of heat for each unit of electricity.
Does cold weather raise heat pump cost?
Yes. Efficiency falls and backup resistance heat may run during very cold conditions.
Power saving devices: do electricity saving boxes actually work?
Does Power Saver Pro electricity saving box actually save electricity?
No. For fake plug-in boxes (StopWatt, Power Saver Pro), savings will be 0 kWh ($0.00) because they do not reduce active power. Residential meters only measure active power (kWh), so improving power factor at home changes nothing on your utility bill. For legitimate power-saving devices (smart power strips, programmable thermostats, timers), use Daily kWh Reduction = (Original Watts x Original Hours - New Watts x New Hours) / 1000, and Monthly Savings ($) = Daily kWh Reduction x 30 Days x Utility Rate per kWh. Example: a TV setup (TV, soundbar, game console) drawing 30 Watts on idle/standby for 20 hours a day is 0.60 kWh/day = $2.88/month at $0.16/kWh. A water heater saving 500W x 1.5h is 0.75 kWh/day = $3.60/month. Verify real-world consumption with a physical power meter such as a Kill A Watt meter.
Is StopWatt energy saving device scam or legit how much does it save?
StopWatt is a complete scam. It saves exactly $0.00. Testing by consumer protection agencies shows it slightly increases your bill because the internal LED draws power. Red flags: "Stabilizes voltage & power factor" (false for residential billing), "Cleans dirty electricity" (marketing buzzword), "Endorsed by Elon Musk / Shark Tank" (100% fake deepfakes), "Cuts bills by 60%" (independent teardowns show only a cheap capacitor and an LED inside). Real savings come from adjusting the thermostat, lowering the water heater to 120°F (49°C), and using smart power strips to eliminate phantom standby loads.
To price a genuine saving, use Daily kWh = Watts × Hours ÷ 1000 in the Real kWh Savings Calculator.
