Chainsaw Usage
Comments (1)Thanks...See MorePropane Usage Question
Comments (10)Propane is the most expensive heating fuel in my area with a cost of $28 per Million BTU. $2.05 gallon contract price with 80% furnace. Heat pump is around $5.50 per million BTU with rates at $.055 Kw for separately metered heat pump. I used 500 gallons of propane from September to February. Very mild winter in a 1650 Sq ft house that is decently insulated. (In Missouri) Getting ready to install a air HP with propane back up. Hope to cut my propane use by seventy five percent. Additional ducting being done with the install. Current 80% propane furnace with 10 SEER 2 ton AC (undersized) New 3 ton AHRI rated HSPF 9.0/ 17 SEER 2 stage heat pump with new variable speed, modulating 80% propane furnace as back up heat....See MoreHeat Pump Usage Questions
Comments (7)I've had a heat pump for 8 years. I don't do setbacks so much any more for the last couple years as I primarily work from home now, but previous to that, I did a 9°F or 10°F setback for 12 to 14 hrs (11:30 AM to usually 1:30 AM) on Mon - Fri. I have the auxiliary locked-out until the ambient temp is below 25°F (it still runs during defrost cycles). Being near Houston, there's not so much freezing weather, but in the few cases when there was, the system ran continuously for up to 6+ hrs to recover. I never considered that a problem. It produced airflow that was warmer than the room temperature (EVEN with the auxiliary locked-out), so the indoor temp kept rising, albeit slowly. We had a record-making/breaking snowfall on 12/4. Snowed pretty much the whole day, below freezing through the night, but bottomed-out at 26°F so was still above my lock-out point. What with the precipitation, the outdoor unit was icy for pretty much the whole day and likely triggered defrost every time the control board checked for it. But ... it STILL kept the house warm, DID actually cycle-off a few times, and 20 mins or so of auxiliary during defrost every 90 mins (or whatever is the defrost check-period) is better IMO than running solely on auxiliary. Anon1111, there are thermostats specific for heat pumps (which yours may be) that have a smart-recovery feature. When programmed for an automatic setback/recovery, they "learn" the operating characteristics of the system over time and start the recovery a little early, automatically raising the temp slowly to avoid triggering the auxiliary. Note that manually raising the temp does not invoke smart-recovery, so the auxiliary will come on in that case ... unless you have the lock-out option installed....See MoreCurious about electric usage - easy question
Comments (4)To answer your last question: Having a lot of unused wiring and outlets does not create any additional use or waste. Congratulations on thinking green. More of us need to do so. The idea is to reduce energy consumption, and thereby pollution, on a global scale. As the others have written, anything with a transformer (AKA a "wall wart"), devices operated by remote, and things with a built-in clock, draw a small amount of power at all times. In an average home, this could add up to 50-100 watts. Take the average of that range, 75 watts, which amounts to 1.8 KWH per day. Multiply X 365 days per year = 657 KWH. Multiply x $0.15 per KWH = $98.55 per year spent just to power these devices. Although this example doesn't consider the time of actual, productive use, you get the idea. Now, this amount is probably a pittance of your actual electricity cost. The idea is that if a large amount of consumers reduce their demand even slightly, the global impact is immense. Remember that the electricity you use is mostly produced by burning fossil fuels or by nuclear fission, both of which have long-term environmental implications. In the coming decades, we will see a pronounced increase in use of wind, hydro, and solar power, perhaps tidal power, and with a little luck, research will result in hydrogen power and nuclear fusion becoming viable, efficient, and affordable energy sources....See MoreHU-178658043
