Re: Replace B&G 100 or use Taco 007 monoflo
I was called into a job years ago where my brother in laws father (in his 90s) was complaining that his addition on his house was cold. He had an old gas fired steam boiler with a tankless heater that heated the HW loop for the addition. There were 2 or three CI rads and they had piped a split loop 1" supply and 2 3/4 returns. (way overkill) He already had every local plumber look at this with no luck. They had monkeyed with this for years. They had taken the CI radiators out, put baseboard in and then put the CI radiators back in. I don't think it ever worked right. I think as his father got older he couldn't tolerate the lack of heat.
It had a Taco 110 circ.
After staring at this for a while feeling the pipes and bleeding the system I stood there looking at the tankless coil with it's 1/2" connections and pictured how much 1/2" tubing it took to make the tankless coil.
I upped the pump (forget what I put in) and it was fine.
I never missed when sizing a pump for a new job but going to an existing job that sort of works it gets in your head.
You have to step back , start from scratch gather some information and figure it out.

The spinner seems like it is going to get a lot of debris in the tubing.

Re: How to seal exhaust flue pipe?
Unless things have changes furnace cement is all you need. Chip off the old and neatly apply the fresh stuff. It's not there to keep flue gasses from escaping it's there to assist with keeping a measurable, consistent and controlled draft at the flue.

Re: Thinwall plastic pipe identification
might put a hose down it and make sure the water actually drains away somewhere. make sure the grade slopes away. the drain tile or the storm sewer connection or wherever that goes might be clogged

Re: New Build
Something to keep in mind is that as building quality increases (specifically as the number of holes in the walls decreases), floor temp required decreases.
Re: High delta T losing hot water
Repipe the indirects with a dedicated circulator for each and use 1" piping to and from the boiler. Your problem will disappear.

The three choices for radiant floors
High mass concrete slab 4" or more
Medium mass 1-1/2" over-pour or 1-1/2" gyp pours
Low mass, plates below the flow wood or foam panels on top of the floor with aluminum surface, UltraFin convection plates
In a climate that sees often and wide temperature swings, the light, low mass systems may be the best choice

Re: Heating recommendation for Jackson, WY
The electric radiant ceilings were known to get uncomfortably hot on your head, especially for tall people. Same with IR tube heaters.
A properly designed hydronic radiant ceiling should not need to run uncomfortably hot. It is all about heat load, and surface area. The more area you have to spread the BTUs the lower the operating temperature.
With ceilings there is not typically any furniture, walls, appliances, etc in the way to block output, so you get a massive radiant panel. With no bare feet touching the ceiling, you can run higher surface temperature if needed.
An 88° ceiling surface gets you 36 BTU/ sq ft!

Re: Thinwall plastic pipe identification
Unless that seeping is with a slow trickle of snow melting off a roof for 2 days then it has a chance to soak in to the ground next to the foundation and leak inside.

Re: Thinwall plastic pipe identification
try some pvc primer on it, see if it softens it. I haven’t seen a pvc/ abs pipe like that before?
