Re: Gift Wrap Your Message
A great story. I also couldn't help but feel the relationship from one generation to the next. I'll explain.
@Erin Holohan Haskell Opens the circulator as her, after Christmas, Christmas present. 30 years later, she purchases the business from her father@DanHolohan, continuing the "circulation." The entire story hits home in so many ways.
Thank you for sharing / posting.

Re: Geothermal Installation Video
Awesome. Professionally done and your voice over was perfect. Did you use AI for the voice over or are you that good?
Re: At my whit's end with banging pipes, squirting vents and No heat! Please help!
I'm sorry for your aggravation. Instead of sending the same hapless crew back over and over, your landlord needs to pay a Professional Steam expert to come in and evaluate the causes and provide solutions. The Find a Contractor feature on this site is where they can be found. Good Luck. Mad Dog
Re: Antique steam heat boiler/radiators
We did discuss relocating the boiler. I have not ruled it out. But until we get the asbestos off the old one I won't know the best option. And you are right the labor to remove the old one will be significant.
We are exploring the new conversion burner as a viable option. Most of are vendors are closed today or we would be on it.

Re: Anyone know about disassembly of these full-port Webstone (Nibco) ball valves?
Just had a job where I used use of Locktite to seal slow drip on nibco ball valve. Steps are:
Drain system enough to remove pressure from valve
Clean all corrosions off valve body
Heat valve body with torch for short period to drive off water
Apply locktite 290 sealant; I find a couple drips on top will flow around entire joint on horizontally mounted valve
Wait 5 minutes and reheat for short period for to cure Loctite
Apply pressure.

Re: heat pump water heater with domestic coil backup
Thats just how I drew it. When I do it I'll make sure the expansion tank is below the shut off for the tank
Re: Blower motor shaking but not starting
Wow, what a difference! I definitely had the motor turning the wrong way. It sure blows out of the vents now!
I bought a voltage metre so would someone please tell me what I should be looking for?
Re: How efficient is my boiler? No really
I don't much care about the boiler rating. I care about the money I save. I leave the efficiency to the lab experts. I attribute the saving to the modulation and the outdoor reset features. God bless those engineers.
Now if they can only design a mod/con that last 40 yrs, but that would probably hurt their bottom line.
Re: Burner Cycle Time
you want to protect the boiler from thermal shock, most importantly. And ideally you would like nice long burner run cycles while maintaining return protection
Somewhere you will have to compromise. The heat load of the building is ever changing. If you were to adjust and install a bypass now in mild weather the dynamics will be different in full load heating conditions.
Lots of variables come into play. Is the boiler sized to the radiation? Is the radiation sized to the design load? Has the building or insulation changed since the install and calcs?
You may not gat a perfect long, efficient burn, in all load conditions regardless of the bypass, need to figure out all the variables.
The 10 minute minimun burn seems to be the number most of the respondents used when asked about cycling in the article. You should have good return temperatures in that time frame. Still think I would be more cocerned with the return temperature than the on / off cycle. Doilers will work with shorter cycles, drives me nuts, but plenty run their entire life short cycling. Low mass boilers do this commonly in low load conditions.
Sounds like you have a handle on the concept, but not quite sure how to fix it to you system. BP does a lot of these sucessfully, I'd use his method.
