Re: Your advice on a Chiltrix chiller
If you go this route, don't forget that you'll have to fill it with glycol - in spite of what the instructions may say. If you lose power when it's cold, there's nothing to keep the HX and external piping from freezing.
Re: Leak test at 550PSI per the manual?
I have done conventional AC at 500 for 12-18 hours.
Mini's at 300 to 500 for hours.
Quite honestly it depends upon your time window and how much is in your tanks! I have at least 2 tanks to cascade with.
I am sure I am not alone is this get er done fashion. But I feel confident that I have done justice to the leak check procedure.
I also triple evacuate everything, this can involve hours.
A leak will show up in vacuum testing by rapid rise with pump off.
However, you want to be sure you have all air purged before high pressure testing. Air will contract overnight and drop your pressure......and likewise expand with warm weather.

Re: converting radiators to hydronic
Hello, i want to get rid of them cause there always in the way of furniture. I was also under the impression that radiant was more energy efficient. Also i get temperature swings, the 1st floor will be 72, while the 2nd is 78. right now it is 1 zone. I also would like the warm foot feeling. ...On more energy efficient? Nope. Nor is it less. The energy efficiency is controlled by the relative envelope -- building -- tightness and the efficiency with which the heat source -- boiler or power plant -- converts fuel to heat. How you get that heat into the building from there has very little to do with it, although the adequacy of the controls may have a lot of influence.
How close in feet do the loops on one manifold need to be if they have balancing valves on them?
On the temperature swings -- again, that's a control problem, not a heat source problem. Switching to radiant won't help that a bit; making multiple zones of your present system, with proper controls, would.
I'll agree with the warm foot feeling. It is nice. But to tear out an existing system which works, although perhaps with poor controls, to put in a whole new system for that? Um...
On the close in feet question -- it's not just the length in feet. The number of bends in the layout and the number and type of other fittings factor in
Re: Wiring
It doesn't require power. The terminals are plain switches, and it is wired in series will all your other safeties.
Re: Lochinvar vs Navien High Efficiency Boilers
110K at design seems high for a typical residential house. For example, I am heating 2,000 sq.ft. of 1965 era construction split level house with a design load of ~35K (western Mass, 0F design temp). I have a Lochinvar WHN055 that I have set to fire no more than 67%, have no problem keeping the house warm, even at -10F.
Do you heat with natural gas now? If yes, you can do a check on the 110K number you calc'ed by using the gas consumption usage method to estimate heatloss.

Re: Frequent replacement of black pipe nipples and other fittings.
What valves are you opening here? The weekly flush of the LWCO should suffice: (open drain valve until running clear).
You could do a monthly flush of the boiler drains to remove any accumulated sediment.
Opening all the valves once a week might introduce 4 or 5 gallons of fresh oxygenated water into a system which may not fire for a few hours, thus exposing those thinner pipes to corrosion.—NBC

If you look at the very first picture it looks to be the auto water feeder valve??
Re: Home AC Compressor High-Side Pressure Cycling
If the condenser fan is running normally then the condenser coil probably needs cleaning. Spray coil cleaner on it and flush with water. Follow the directions on the coil cleaner and folly good safety practices. Power off, rubber gloves face protection.
