Re: Objects found in heating systems
For me it was working in office spaces with lift out ceiling panels. You pop a tile measure something or do some work move the ladder do some work move the ladder etc. etc.
At the end of the day you pop all the panels back in, then you find out you missing half your tools that are in the ceiling and don't know where they are.
but i found some good stuff others left behind as well.
Re: I get all the weird ones...
Tell them straight up, it's not going to work. They need to figure out a different strategy for material handling. Without knowing the process, I can't really offer suggestions. If they insist on trying to heat a 5k sf building with a 22x18 door hanging wide open, walk away. Working for idiots is financially risky and you won't get any satisfaction.

No, Fix what you have. it would cost a fortune to make it two pipe and you will need a new boiler in the future.
Re: Need help with new install of radiant with Buderus cast iron boiler
Let’s backup for a moment and get some basic info.
Was a Manual J load calculation done to determine the heat loss? If so, what are the results?
What size is the boiler?
I see 4 loops on one manifold and 3 on the other. What are the tube sizes, the spacing and their lengths on average?
The reason that I’m asking is that unless you’re in a mild climate, it looks like that you may be under-radiated, in which case you’d need some supplemental emitters. If so, that would change the approach.
I apologize for not asking these questions first, but I went directly to addressing your questions without noticing the number of loops.

Re: Asbestos?
Have to have it tested to know for sure. Could be asbestos, could be cotton or wool or something like that.

Re: Water to Water Geothermal heat pump replacement with lp boiler
If you are switching to resistance heat often, your COP or efficiency may not be what you assume.
Some installers add a small Kwh meter on the HP to see what it is actually consuming.
If the resistance is in fact being used or over used, the LP starts to look better.
Some GEO issues are not easily fixed if you have a well, pond, or loop field that is not up to the task.
All this is knowable with some number crunching.

I can add my own trap on the white pvc before the open funnel. as pictured.

Re: Replacing pressure reducing valve
is it possible the white pvc just sits over a floor drain that is trapped? If so that is an indirect waste, and legal.
