Re: Are these my main vents? What to replace them with?
Can’t believe I didn’t think of this before. I have matching radiators in the bedrooms. I went to the other bedroom, took the cap off and it’s exactly the same as the other, so I put it on the radiator with the broken cap and was able to open the valve all the way. I’ll still pick up one of those universal ones and see if they will work but at least the valves open now. Thanks again everyone!
Re: Indirect HW off steam- shaking circulator
thank you, I’m aware the bypass loop doesn’t provide heat. But the lack of heat should incentivize someone to check the screen.
As for the bypass loop I believe you, I’m just going by what Dan taught me. It’s nice to be on the right side of that argument lol
Re: Mitsubishi heat pump not keeping up
I would not be surprised if low on charge from start or a leak. Someone will need to weigh out charge and then calculated what’s needed and weigh back in. Talk to installer and see what he charged with? Maybe just used pre charge weight? Knowing what it started with will help determine if leak after current charge weighed out. Takes competent refer tech.
2 videos this week, Hot Rod sent me a video on backflow preventers and i talk about time delay relay
In Hot Rods video, he discusses troubleshooting backflow preventers. It's really interesting. Here is the link to Hot Rod's video.
My video is why should you consider a time delay relay for your cast iron hydronic boiler.
Re: Good old boy efficiency (burner limits)
It is obvious that @Robert_H is asking for the proper way to fix this insufficient hot water problem.
Duct Tape and a Sharpie would be my suggestion.
Re: Energy Kinetics EKF1 - New installation not heating radiators as hot as previous boiler
Yes, the link you sent describes smart boost and its operation. Feel free to Dm me if you have any questions.

Re: Heating an Old House: Gas Heat Options
This is a very charming nice looking house you have. The front looks great and from what I can tell it will even look better as you continue. I especially like the kitchen. I truly do, right down to the dog. I hope in the future you will post some before and after pics.

Re: Indirect HW off steam- shaking circulator
Perhaps I can encourage them to add a strainer while they are re-piping it anyway. That is after all, depicted in the Burnham diagram.
Re: Indirect HW off steam- shaking circulator
These circulators are designed to work with a certain amount of pressure. Steam boiler have close to zero pressure as it is and you would like to eliminate anything that might reduce that pressure.
