Re: Tankless Coil Intermittent Hot Water
I just want to thank everyone for their insight and suggestions. The hot water supply has been much more consistent over the last 24 hours after making adjustments according to your advice.

Re: "Navien Combi Boiler: PSI, Gas Consumption, Condensation, and Baseboard Concerns – Seeking Advice!
do you think it will be more efficient if it runs more than 120 hours biweekly ? I just disable outside reset temp and set the water temp to 135f. The return is coming @ 126f. I will take a lot at the consumption tomorrow. For context, the outdoor reset temp was always @ 150f.
yes - that boiler can modulate so during especially cold weather it should run near nonstop. 150F was too high, 135F is a good temp to try. Lower temps at higher outdoor temps is the key.
Re: "Navien Combi Boiler: PSI, Gas Consumption, Condensation, and Baseboard Concerns – Seeking Advice!
It sounds like the choice of a mod/con boiler with baseboard heating is a questionable choice for your location and building type. The "lowest hanging fruit" for you to "grab for" at this point is building envelope improvement i.e. air sealing first, then improve insulation. Then, you can focus on improving the operation of your boiler by 1. reading the manual 2. having a combustion analysis done, 3.installing the outdoor sensor and dialing the boiler in to all of the appropriate settings. This is the best you can do right now with what you have. You could install some more baseboard in the future. In the end, your fuel bill will inform you HOW WELL you did!

Re: Type of fixture ?
Hi, Gotta comment on the brass cartridge. Moen had a problem with crossover with that cartridge, They advised me to go with the plastic one instead. I've never had a problem with the (polysulfone) plastic ones. 🤔

Re: Type of fixture ?
Time was when the Moen rep would give you a handful of cartridges. Since they were sold as lifetime warranty.
I actually like the plastic cartridges better. They seem slippery and less prone to scaling up.

Re: Type of fixture ?
Moen 1225 cartridge replacement. It comes with a plastic tool to put over the old cartridge to spin it so it comes out easily.Make sure the water pressure is off it.

Re: Tankless Coil Intermittent Hot Water
I'll add my experience is that mixing valve doesn't do well in hard water. You can check its function by quickly touching the three pipes going to it to see if too much cold is being mixed in.
