All 3 untis are heat pumps,
Sorry, I was not specific enough. All the systems will be heat pumps, the upper floor and the studio will have electric heaters not gas..
All the comments and suggestions are great
Thanks for the reply, I will make sure the HVAC guy knows about the windows.. Hey, if I can reduce size, great, less cost to buy, less cost to run. I will get with them perhaps this week and discuss the loads..
I did mention to the HVAC guy that for the downstairs I'd rather have more heat so that is why we went to a dual fuel option, this house has it ,and it's nice when needed, although, who knows, perhpas the heat pumps today can actually heat enough with out the gas, but when the temps really get down (this year to 9degrees) it will be nice to have a back up..
I'll mention the potential over size of the air concern, that was an excellent point about humidity.
We moved here in May from Southern California, so, the weather is completely different than what were use to for sure..
Berad, thanks, couple of questions for you.
I really appreciate the work you put in to this, I did see the thread on the heat and cooling days, and I did go to the site via the link. Im not sure how thoes numbers get calculated either.
Now for a couple of stupid questions.
1. The "Season" use, is that the total amount based on the numbers from the chart and do I assume that would be for per year? (not per month)?
2. from what I have seen in this house the secondary gas hardly kicks in at all unless we get below 30 degrees and that would also depend if I tweek the thermostat a little warmer. Your probabaly pretty close on the cost of fuel, I think we probably average $1.10 per gallon here recently. I know that at times it is quite a bit higher but we can get a level pay plan that would probably averate the $1.10 costs.
It seems pretty consitant the savings are about 30% from the 10 to the 14 seer which seems pretty good, even better than the Mfg specs, but, its still minimal overall vs. the cost of the upgrade (ok Im not going to get in to the price issues).
It will be intersting to see what our electric bills end up once we get in.
With the new specs for the EPA going to 13 this coming year it will be interesting to see if the units get more competitive as more units get changed over. I'd probably be happy with a 12 SEER, or possibly a 13 seer unit just to be up with the EPA.
Now given your comments about the heat pumps, I wonder if anyone else will chime in on the figures on heat pumps.
I really appreciate all the work you have done, if your ever in the Nashville area I deffinetly owe you a lunch.. thanks so much for taking your time and taking the effort to provide me with some numbers to work on..
