The sizes were not from HVAC guy yet
Thanks for the information, Geeze, maybe I got a step ahead of myself, and I am sorry I did, I have not sat down with a HVAC guy yet, the contractor just did an estimate on costs and kind of thew out some sizes but I may have been wrong with the sizes.. sorry... Your are right, I do need to sit down with the HVAC guys to go over the house and sizes and hopefully I'll get to that his week...
The cost of electric here in our area is .066 per KW, so fairly cheap. Propane, well if I buy in summer it was about $1.00 to 1.10 per gallon, I'd put up a 1,000 gal tank that would hopefully take me through the winter high cost months..
Does that help? (and yes, the house is going to be tight, and energy efficent windows)
Thanks again for all the input!
I agree, a pro HVAC guy is needed and that Is what I am going to do, I am sure that is what the contractor would want as well, he has given me a few guys that he works with all the time as well as I'm looking in to others. I should have a set of plans that make sense in about a week or so, that way I can sit down with 2 or 3 HVAC companies and see what they offer.
I am going to explore the costs of straight electric vs. dual fuel, your right, the simpler the better, even if the Eletric could cost us a little more from time to time, I need to find out what the premium dual fuel system will cost me. The Electricity here in the Nashville are is quite low, and the price of propane is quite high, I just need to find out what the difference in dual fuel ves straight electric will be and make my decession..
Keep the comments and suggestions coming, I realy appreciate the input.
perhaps, a little more info can help this discussion.
The home is a Craftsman style, with a raised foundation, hopefully we will have a good crawl space of 2 - 3 feet.. the construction is wood frame, 2x4 design, r 13 outer wall insullation, all voids sealed and filled (actually the contractor is very good about this), the outer design will be about 1/3rd up will be rock with Brick up from there. No siding what so ever, its all either brick or rock all the way. the windows will either be the top of the line Pella insulated, low e with argon gas, Wood - aluminum clad windows, (not home depot, but pella direct) doors will be all sealed tight dual insullated doors (french doors will be insulated glass) full insullation under the house and I am shooting for R38 in the attic areas. I am using 5/8" drywall instead of 1/2 inch just because I like the solid feel and our last 2 homes have been 5/8 inch.
I am confident in the contractor, we have seen many homes he has built, so, his construction methiods are top notch (matter of fact, most subs tell us he is the pickiest builder to work for in the area) he builds each home as if it were his own.
The only thing we are dealing with is the heat pump issue at colder than 40 degrees.. the current home as I mentioned when the thermostat is set to 68 and the Aux gas is not kicked in the house feels cold, but I kick up to 72, the aux gas (propane) kicks in and were tosty warm..
My big questions had to do with equiptment, Standard Heat and Air Electric, Heat pump system with out a dual fuel system and then a heat pump system with dual fuel with the fuel being propane.. I probably should have not brought up the size at all, that was my mistake., sorry!
And, Im not asking for specific prices but the trade offs of 10 seer, vs 12 vs 14 seer units with the above characteristis..
If I were to use a 10 seer all electric as a base line what would the 12 or 14 run as a percentage increase.. then, add to that dual fuel.. there has to be a way to get an idea.. like 10% more, 20% more or what.. where is the break even point, we plan to be in this home for quite sometime, our last place we were in for 14 years.. and as I said that was a lennox system from 1991 Electric Air, Natural gas heat..
I hope this helps a little more..
