you crank out a lot of content, keep sharing your knowledge.☺️

Re: 9 kW Mini boiler reset problem
You need to have the boiler checked by a technician that knows electrical and knows how to troubleshoot. The boiler should not be reaching the high limit temperature
Re: How to delete boiler coil and replace it with a HPWH
I agree with your HPWH decision.
This Idronics issue, liked below issue talks about HPWH in general and some of the concerns with recirc and HPWH.
Check out the Metlund® Demand recirc system. I think that is a good match for HPWH recirc systems.

Re: newer wall furnace with one sided heat.
hate to say this but with your symptoms I would strongly say do not run this unit.
I don't know if this is propane or Natural gas but call the gas supplier or the fire dept and have it checked. Landloard is an idiot.
I would not take any chances with this.
Re: why does my radiator valve have a hole in the gate?
The hole is there to allow a tiny amount of flow and thereby prevent freezing. It’s typically not enough to actually heat the radiator up.

Re: After two heating seasons freezing point of radiant heat system has gotten lower
I would chalk that up to meter or operator error.. If this is a closed system the water cannot separate and evaporate out?
The numbers for glycols are
Freeze point, ice crystals form, fluid still flows
Slush point, fluid turns to a slushee, cannot be pumped
Burst point, fluid freezes solid and can break pipes and tubes, even Pex.
It depends on the brand of glycol, generally 30-35% mix is adequate for burst protection.
The higher percentage is harder to pump and transfer heat from. No need to overdo the glycol mix.

Re: Copper pipe radiator design
Something like this would be best. They are/can be small to accommodate your small bathroom while heating the space adequately.
While building a piping arrangement for a small space can work. The piping can be laborious, unsightly, and may not heat the space as well as you want. This is one reason why radiators were invented.
Do an EDR as mentioned above and do the job correctly with no regrets. And as far as cost goes, it will be a little more. But not so much that you will have regrets. Heck, you could probably find a used radiator on the cheap or even free in good condition that will work for you.

Re: Mystery water leak - excess water take up problem
If you’re seeing white smoke from the chimney, you probably have a leak in the boiler block above the water line.
Turn the boiler off and temporarily fill it to the top of the block. If you see water then, it’s leaking and needs replacing.

Re: Intermittent vs. Interrupted
From the little bit of experience I had it seemed like interrupted was quieter. It also probably wears the electrodes less and uses less electric, no?

Re: Building pressure and the effect of abandoned mains
either the boiler or the return is above the emitter. i don't know the exact physics of how it works but it is common on commercial 2 pipe steam.
