Seattle- Heat Pump/Gas Furnace vs AC/Gas Furnace
Comments (13)You should definitely be pricing with just heat pump. I live in NC which probably is a bit colder in the winter. We get down to the teens but only 15 nights a year maybe. Our winter average low is about 30. Under 10 degrees is definitely a news story. I have 5000 sq ft. I'm looking at my NG bill of $30. I have dual fuel and seer 16 heat pumps. Last winter was very cold and I spent about $700 with $200 being gas. This winter is going to be $120 in gas. My electric rates are similar to yours without the first 1000 discount. What is my point? Your gas usage will likely be $100 a year. Even if that were replaced with all heating strips, you'd be saving $200 a year or so. Since it would probable be 80% heat pump still, the dual fuel is only saving you $40 a year. So a $2500 furnace to save $40 a year seems a little crazy (on dollars alone). Turns out for me, it is probably worth it but only marginally so. I have a 90% (which you should be able to do as mine is basement with horizontal PVC exhaust). It probably saves $60-$70 on an average year. Probably cost $2000 (new house - I can't remember). What is that a 30 year payback (or never if you count interest or NG rates increase)? You do get some flexibility and you can setback at will with dual fuel. That is worth something....See Moreheat pump/gas furnace or AC/gas furnace
Comments (17)The DOE has worksheets that can help you calculate the relative cost of heating and cooling with different systems using your current energy costs. Of course you need to predict the relative costs over the next decade or two to really tell what is best. How is your crystal ball working? I would like to clear up a couple of common misconceptions. One type of heat does not dry a house in the winter any more than another. Leaky house envelopes dry houses. Heat by flame of some sort might dry a house more because they draw more outside air in if there is not a source of outside combustion air. That would be the only mechanism. There is nothing special about heat pumps in poorly-insulated, leaky homes. No heat or air conditioning source works as well in that situation as well as they do in tighter, well-insulated homes....See MoreAC + gas furnace vs, Heat Pump + furnace
Comments (5)All units are Bryant Furnace = 355BAV A/C = 127A Heat Pump = 226A Had to order today to take advantage of rebate offer that ends 8/31. Never could figure out how to estimate the cost of running the heat pump vs. the gas furnace and couldn't locate any on-line calculators/spreadsheets that would help. Figured I'd save a bunch with new 95% furnace over the old sigle-stage 80%, and the new 17 SEER a/c over the old single-stage 10. It's small house (1450 sf) and well insulated, and I didn't know if I'd squeeze enough additional savings with a heat pump to justify the extra initial cost of the pump plus whatever extra cost would be involved in replacing it sooner because of running it much more. When in doubt, play conservatively (at least where money is involved), so I went for the a/c unit. Wish I'd discovered this website a month earlier. Thanks to all those who responded....See MoreHeat Pump vs Gas Furnace/AC - Help!!
Comments (2)It depends on where you are located geographically. I have what is called a dual fuel system--heat pump and natural gas. My heatng bills are about the lowest in my subdivision of 64 custom homes (the gentleman with radiant floor heat and two other guys that burn wood pay a little less). Folks in our subdivision that use natural gas furnaces only have much higher bills than mine. Folks that don't set their heat pump balance points have heating bills higher than mine. I set mine so the natural gas furnace doesn't kick on until about 25 degrees outside. I am well insulated with great windows, energy efficient and have a 3.5 tone HP for 2,981 sq. ft. 1.5 stories. Depends on your home envelope, too. Check your electric and natural gas rates which includes delivered price (i.e. total cost you paid for electricity including service charges divided by total KWH and total cost for gas including service charges divided by total therms or Cubic feet used to get your real world costs. In my case, natural gas needs to come down about 35 cents delivered price before it breaks even with my electric. Your rates will likely vary....See MoreElmer J Fudd
