I have no direct experience with the oven, but you can calculate it's energy usage. It's simple. Multiply 117 x Amps used=Watts (approximately, but good enough for every day use) Let's say it comes to 1,000 Watts. If you used than amount of power for 1 hour, you have used 1 Kilowatt Hour, or 1 KWH. In most parts of the country that costs about 8.5 cents worth of electricity. In general, the kitchen only uses 10% of total household energy, a pretty small amount. The fridge generally uses more energy than all the other kitchen appliances combined.

I am starting to build a new home. We are in East Tn and the home site does not have natural gas. I am looking at installing an electic heat pump. Our living room is in a central location on our 2000 sq ft main level where the fireplace would be located. Would I save money by purchasing a larger lp direct vent fireplace and use it as supplemental heat to the electric heat pump? Or should I just by a small unit to get the look and spend the money elsewhere? I can get a small lower end unit that still looks nice for around 2500. But a large high output unit is pushing 4k - 5k. Thanks Dustin

I was trying to gauge the cost(for natural gas) when my furnace has run(consumed gas) for an hour's time. I did it two ways. First I just took the BTU input rating of the furnace and did the calculations from there. Then someone pointed out that the BTU input rating may not be an actual value. So secondly I needed to determine the amount of gas my furnace is actually consuming per hour. Here are the particlars: 1. I have Goodman model GMPN100-4 furnace. (natural gas, single stage, pilotless and an input rating of 100,000 BTU per Hour) FIRST WAY USING BTU INPUT RATING: 1.One cubic foot of natural gas has about 1,030 BTU. 2.Divide the furnace input rating(in my case 100,000) by 1030 to get the number of cubic feet of gas the furnace will use in one hour. So 100,000(BTU) divided by 1030(BTU per Cubic Foot) is about 97 Cub Feet. 3.My supplier's bill is based on units of one hundred cubic feet(CCF) so I divide 97 cubic feet by 100 to determine how many CCF the furnace will burn per hour. This turns out to be 0.97 CCF 4.My supplier charges $.745 per CCF so it costs me 0.97 times $.745 = $.72 per hour for natural gas for my furnace to run. SECOND WAY BY DETERMINING ACTUAL GAS CONSUMPTION: As stated above someone pointed out that the BTU input rating may not be an actual value. So I wanted to determine how much gas the furnace was consuming per hour. My gas meter has a 2 cubic foot dial. I set a video cam in front of the gas meter in the morning knowing the furnace would be on for at least 20 minutes to bring the house up to temperature from the night's setback. The furnace did run for about 20 minutes but I stopped my readings at 10 minutes. Here are some findings: In 5 minutes the furnace consumed 7.6 cubic feet of gas. In 10 minutes the furnace consumed 15.2 cubic feet of gas. So 15.2 cubic feet of gas in 10 minutes extrapolated out to 60 minutes would be 91.2 cubic feet gas per hour or 0.912 CCF/hr. At $.745 per CCF the cost is about $.68 per hour. From the input rating data (100,000 BTU/hr) I calcualted .97 CCF/hr. So the actual gas consumption was a little bit less that the input rating. Now some Notes: 1. My gas bill is broken down to a charge for gas consumption, a customer service charge of like $21 a month and of course the tax on the consumption charge. So it's pretty straightforward how much the gas costs per hundred cubic feet. This month gas was $.745 per CCF. 2. No other gas consuming appliances(oven, stovetop or hot water heater) were firing at the time of testing. 3. I understand that outside temp, thermostat setting and how well my home is insulated are factors as to HOW OFTEN the furnace will run. That wasn't my concern. I only wanted to know how much gas was consumed when the furnace ran for an hour. How that hour was achieved was not important. It could of been 60 continuous minutes or six 10-minutes cycles. In my case I took a 10 minute run cycle and multiplied that amount of gas usage by 6. I have since I've hooked up the following 24V hour meter to the gas valve: http://www.grainger.com/Grainger/REDINGTON-Hour-Meter-2PPV9?Pid=search The meter progresses in tenths of an hour increments anytime the gas valve is open. I can tell how long the furnace runs each day, month or season. This helps with filter changes also. I've found that about every 125 hours the filter is dirty enough to be replaced.

There is some missing information that would be needed to get an accurate result but I will try and fill-in the missing pieces. You can make modifications as necessary: Inputs Pool Size: 15,000 gallons (average 5' depth) Pump: 1.5 HP Full Rate Whisperflo (pump model makes a difference) Plumbing: Minimum 2" return pipe, 2.5" suction pipe, 30' runs (typical plumbing) Energy Cost: $0.15 / kwh (varies a lot by region) Turnovers/day: 2 Outputs Flow Rate: 93 GPM Head Loss: 64 FT. Turnover: 2.7 hours Cost/month: $56 Check the inputs and see if there is any differences to what you actually have. If you have a spa, you might actually want a larger pump for the jets unless you have a separate pump for the jets which then you may want a smaller circulation pump. However, in any case consider a two speed pump because on low speed, the cost would go down to about $28/month for the same 2 turnovers.
