Re: Help identifying contactor terminals
@Alan (California Radiant) Forbes
Leave it to the MFGs to come up with the screwball ideas just to screw everyone up.
I can remember when Scroll compressors first came out and the MFGs said basically " you don't need a CCH with a scroll they will eat liquid" Carrier junk was big on this. After they started replacing compressors they changed their tune
Re: Axeman-Anderson oil fired boiler vs. Burnham oil fired
1300 ohms is still a bit high. You usually can 800-1000
Re: dealing with twists in the pex , not staple up. I have Omega extrusions now. YAY!
I am working on my shop addition currently. I am getting beams and TJI sized. My AHJ requires a licensed engineer stamp the calcs, regardless if they are from a beam/ joist manufacturer quick sheet, or their own engineering software. It is nice to run some what-if examples before sending it off to the engineer.
It amazes me how large of an opening you can safely put in engineered I-joists!
I've been in a few homes with over-spanned or compromised floor joists. A springy floor is one of my pet peeves :(

Re: Vent placement in home 2-pipe steam heat system
First off, that asbestos insulation needs to be removed. You will need a licensed abatement company for that.
Second, the piping around the boiler is all wrong. That Carrier boiler is a re-branded Dunkirk, and Dunkirks are extremely sensitive to improper piping. The manual is here:
The steam needs to enter at one end of the header, and the drip must be at the other end. The present piping has steam coming in from two directions, which can interfere with condensate (water) drainage.
The vent in the pic is a radiator vent, which is too small. Are there vents at the ends of the steam mains?
How about a pic of a radiator that has an original shutoff valve and return fitting?
Re: Floor Closet Flange Toilet
I have to say that I think they are made better than they ever were. I don't think the move to Mexico made any issue to their quality.
Most modern toilets don't have space for a ballcock, brass or otherwise, and since they have become a boutique item the price is ridiculous.
Re: Whats involved in a refrigerant line repair
Yeah it takes a lot longer than you think to repair refrigerant lines. If this company is doing the work at no charge based on your past business with them it seems like they are probably a good one to stick with.

Re: Minisplit head placement
Hi, Not sure if this approach fits, but I'd use a ducted mini-split in the floor 1 unit and put it just above a lowered ceiling in the hallway that serves a bedroom and bath. From there it could condition those rooms and the Kitchen. With some creative sheet metal work, perhaps it could take care of the living room as well. A separate head for the "North" bedroom seems needed.
For floor 2, If the ceiling could be lowered in the rectangle that is by the stairs and touches both bedrooms and the kitchen/living room, a ducted mini-split could go there and serve the space.
Yours, Larry
Re: BTU kW Sizing - I am pretty sure this is a stupid question but you decide!
Note that you are just changing the temp setpoint of the boiler. It could be using the full input of the boiler to make the water that temp. You don't know without measuring the power it is consuming over time.

Re: BTU kW Sizing - I am pretty sure this is a stupid question but you decide!
use this:
is this floor heating? If so, those temps are extremely high. Why are you operating it like that?
Caleffi’s Idronics journal on air to water heat pumps is a wonderful resource. You have a pretty easy swap here (assuming radiant floors), so that’s exciting!
