Yes I've seen this before as an option. But with the current design, there isn't really a place to put such a utility room on the 2nd floor. The 2nd floor is huge, so it's not like room couldn't be found, but with the design as is, there's not a dedicated space. It's something I'll have to discuss with the builder.Quote:

I am pretty certain the builder has shopped out who is going to do his work for the lowest rate, and that usually does not mean quality work.
I concur..Quote:

If his electric rate is high and his Heat loss is higher than 45,000, then I can agree, till then, I can't agree just yet...
You gotta chill....LOL. Correction on my part......a 5 ton HP will put out approx. 55,000 Btus. I'm just saying (hypothetically), for 3,300 sq. ft. with a full basement, he'll need at least that much heat. Throw in zoning and he'll have a lot of airflow with only one zone calling.Quote:

Is the part in red just your opinion, or is it part of some rule or program?Quote:

-Philadelphia, PA area. Number of days that AVERAGE 32 degrees or below..35. Number of days that the LOW temp drops to 32 degrees or below..100 (basically Dec through mid March). On average, the lowest temp of the year is 23 degrees.
-House will be well insulated. 2x6 walls. R19 in walls, R50 or so in attic. I have stressed the importance of insulation to the builder. Assuming I go forward with the spray foam (builder estimated about $6K extra), the house should be as tight as I can make it.
-Gas is not available unless I want to spend $60,000 to extend the line
-Propane about $2.80ish a gallon
-My current electric with PECO is $.165 a Kwh
-House is about 3200 sq ft., about 1600 on 1st floor and 1600 on 2nd floor. Basement is just as big, and will likely be finished in the future.
-I plan to have an efficient woodburning fireplace (RSF brand..heat capacity 1500-3000 sq ft) in the family room, which should be able to heat much of my home..at least the first floor from what I am told by the fireplace experts. I understand I'll be loading this fireplace several times a day.
-I prefer propane for the range and hot water heater, and I plan to install a whole house generator in the future, so I want to have an underground propane tank (500 gallon or so?).
-My contractor is pushing a 85% efficient propane furnace. I want to do an electric heat pump with a propane backup.
-I plan to be in the home 20+ years.
Noted. I've never built a home before so I simply am not sure of the options I have as far as subs. i.e. if I wanted a different electrician to do the work, I didn't think I could tell the builder to use ABC electric instead of his sub. I assumed the same goes for HVAC but I guess not.Quote:

You can do it yourself off your house plans. Or have someone do it for you. I have seen services on the internet that will do it for less than $100.Quote:

Best of Luck..
