Re: Air Separator degradation...
Its a brass version, correct?
I would take the small cap off to check the needle valve and hinge assembly.
Next open it at the big joint to get to the media inside. Its a glass reinforced nylon media. It should not deteriorate from water. We have seen them plugged with sludge, teflon tape and in one case a brown cotton glove in a large steel separator

Re: How to secure fiberglass insulation wrap?
@EBEBRATT-Ed Im not sure but I think @indierex is trying to add the insulation to make it a little safer for the new baby.

Re: Steam boiler pipe makes water noise
Hello WillS,
Steam piping is pitched to drain condensate properly. If pipe support straps have been damaged, removed, dilapidated, etc. water may collect where it should not be. One pipe or two pipe system ? Pictures help us help you.

Re: Bathroom Radiator - The Wrong Way
I've never seen a radiator like this before. the only things i recognize are the valve and vent. What is going on here?

Re: A heating challenge!
No dust collection is that good. Forget forced air unless a seriously oversized filter system is installed.
In floor radiant
Hot water coils with drains so the coils can be washed periodically.

Easier to just pump all the refrigerant into the condenser with the compressor.

Re: Backup power for an old steam boiler with a standing pilot
Yes Long Beach Ed, you don't want the neutral bonded to the ground in two separate, different places, so you don't have neutral current in the ground conductors. So a DPDT switch would provide the neutral isolation.

Re: Air Separator degradation...
How close is your indirect circ to the air separator? I've seen them pull in air when piped too close.
Re: A heating challenge!
If you really want to get good feedback you may share a few more specifics, like what specifically are you doing with the building? you say a business but what type of business, factory, office, art gallery, retail etc. How many employees? what climate zone? Occupied hours? Are there going to be any large machines in the space? are you processing wood and creating a ton of combustible sawdust? rough sketch of the building as you suppose it will be once finished, general layout and what each space will be used for. Also keep in mind that depending on your jurisdiction you may be required to get an engineer to stamp your mechanical design, and possibly other plans as well, but no harm in seeking advice before committing to an engineered design.

Re: Replacement steam boiler: short cycling on LWCO + NBP BANGING
The EG-75 has an input of 282K BTUH. This is sufficient to heat a small apartment building (I have done it with less). It absolutely requires 3" risers and a minimum of a 4" header………………one could make a good argument for a 5" header.
You have none of that.
Instead of doing the right thing and determining exactly what size boiler you require based upon the radiation, you install a giant EG-75 with totally improper near boiler piping (in copper !!) by unqualified idiots and you expect it to actually work.
Good luck with that.
