I decided on 125A. A 150A break for my main paneltakes 4 spaces and costs about $200 but a 125 is 2 spaces and $75....and should be plenty. So breaker and panenel are ordered, the 125Awith a main breaker is not stocked, it will be a few days.
I need to see where the budget is headed before finalizing plans on the minisplit but the thought is a 3 zone 30k btu, with 9K, 9K, 18K air handlers for the bath, attic, main respectively. This will need a 30A 220V breaker. The fall back is a 1 zone 18k or 24K to save money, but the wire will be there and be plenty big. The one I'm looking at is not the world's best....but is 21 seer and $2300+ a few hundred for lines and wires so say $3k....but 1 zone 15 seer is under $1000 including everything so a pretty big savings.
Lana mensioned the air compressor kicked on in the middle of the night and then she saw the neighbors light come on...could be coinidence but I think the compressor needs to end up inside the finished space to control noice others here. I was a bit worried about the heat in the uncontitioned space killing it anyway...or maybe I'll give it its own little room with a fan so it doesn't smoke up the shop....need to think about that.
I'm thinking I'll do a small electric instant water heater to feed the bathroom and shop sink. They are under $150, don't sit hot wasting power, will keep up on pool party days, and I am running lots of amps out to the shop anyway
This is also by far the cheapest way to warm the floor. There are a couple under $200 propane options but running the line will probably be around $500 plus the vent and I'm at $1000 so I'm leaning toward doing the install electric then upgrade it to propane once the shock of all the spending is over. So 30A line under the stairs too, but I'll wire this 220V which would be enough to actually heat the shop if the heatpump is down.
There is talk that the front lights should be on the switch in the house with all the other front lights...that's a bit of extra work. I'll need to be certain I know about all this kind of stuff..
A lot to keep staight at the moment.
Not sure where you are looking at buying your HVAC but make sure you don't use RocketIAQ. They are a rippoff scam and never ship any products.
