Welcome! Here are some tips for using this forum.
"Fake News" is not fake at all. Calling it fake is just an easy way to dismiss inconvenient facts.
1. Add radiation to allow lower water temps
2. Add ODR
3. Stop using thermostat setback.
4. Live with the fact that it's never going to get above the minimum input.
Throw it out, get a properly sized boiler/indirect. The first 3 apply either way.
And he comes in to work Friday and I said 'pop quiz time' and sent him to the white board. I told him to draw a gravity hot water system, and this is what he did. Mind you, I totally blind sided him with this. I don't think my journeymen would have come up with this. I think he is a keeper! I'm totally blown away that an 18 year old did this.
While the boiler is important, it’s not nearly as important as the installer. Tell us about all 3 installers and how they came to propose these boilers.
I first posted here four years ago. I moved from a 1926 Colonial with hot water heat and bought a 1941 cape with single pipe steam (originally coal now gas). My first winter here almost gave me a nervous breakdown from lack of sleep with the screaming, spitting air vents, hissing valves and banging from water hammer. I learned from you to turn the pressure down, repack the valves, change the air vents, to hire a professional to fix what I couldn't (add main venting) and make sure the radiators were angled correctly. I am going into my fifth winter here and I wanted to let you know how thankful I am.
