Selling 2 hydronic floor heat manifolds that I purchased and used when pouring the floor. I decided to go a different direction when I started assembling the system. I have 1 3 circuit and 1 6 circuit manifold, they come with pressure gauge and Schrader valve for pressure testing. they were...

I am in south Jersey and had a 40x60x16 pole barn installed by the amish 2 years ago for $29.5k, that included 2 10x12 insulated doors, 1 10x7 insulted door, 4 windows and a man door all installed. That was pre covid lumber prices. Your quote seems to be reasonable.

Practice. I am a technician and after a while you get a feel for being centered and square. Its easier when you are pulling straight in, but becomes fun when you are inside a building and need to turn 90 to get into the lift. you don't need to be perfectly centered, unless you are dealing with...

Ok, so after some research I went with Insteon switches, they require a neutral and don't require a hub if you don't want smart functions. Installed 2 simple on/off switches, the remote switch in the house requires hot, neutral and ground only. They communicate over the neutral. Simple...

Ok, so if they communicate over the neutral, would it still work with a sub panel setup? Current setup is the barn and the house are split in the meter box, so main comes into meter and splits to a panel for the house and a panel for the barn. Would they still communicate even though we are...

We built a 40x60 barn in the back yard and it sits about 75ft from the house. I want a 3 way switch mounted at the back door of the house and the entry door of the barn to turn on a large LED flood light that I installed. A friend had suggested the Lutron Caseta switch with the Pico remote and...

here are some pics

Came out this morn and slab temp was up to 55*. We had a low of 23 last night, so looks like its working, I will have to find time to get out here this afternoon and check all the temps.

Ok, I spent 6 hours reworking the system and I have to say that I have learned a TON. First, thank you for everyones input and suggestions, could not have figured this out without the help. So I reworked the system to have a primary loop and 2 secondary loops in parallel. I used another 15-58...

All valves are open and system is purged, I don't believe I have an overheating problem, I have no error codes. Pump should be here tomorrow to create a primary/secondary setup and we will see if it works.

I am pretty confident this is the issue, All plumbing is 3/4 copper so doing anything means soldering, I have unions at the HWH and may make quick bypass for the HWH and see if my flow meters in my manifolds show flow without the HWH in the system if I can get out there today.

Thats what I am describing, primary loop would use the third pump to circulate in the primary loop, both zones would be secondary loops that pull from the primary. See FIG 3 As for pumps I only spent a few minutes looking at curves. I will have to spend some more time looking at them to pick...

Ok, so I think I have a handle on this without the books(on the way), let me know what you think. I know this is far from some of your ideal setups, I am learning as I go and if I can get this to work for a year or 2 and then replaced the heater I will upgrade to a proper boiler. I have...

I totally get it... I am an auto technician and work on and diagnose A/C systems, although they have positive displacement pumps I see similarities in them. Engine cooling systems are even more similar, so I am grasping more and more as I find more info. Thank you for all the help

Ok, now it all makes sense. With my 2 current circulators I must be right at the .5 minimum GPM for the heater to operate due to the unknown to me high internal resistance in the heater. which is why it works for a short time and then shuts off

https://www.noritz.com/wp-content/uploads/2018/05/Spec-Sheet-NRC661-v3.pdf 2nd page gives a pressure loss graph that seems to show that at 6 gpm the heater itself has right around 60 ft of head, I never realized how much restriction these things have. I calculated around 11 ft of head for the...

YELDOGT, I purged the system with a garden hose hooked up to a slop sink faucet. I have one of the webstone purge and fill valves, ran pumps while purging 86TURBODSL, I have the Bluefin manifolds with built in flow meter I cleaned the inlet screen this morning before the baby woke up and it...

yup have one of those, the expansion tank is hanging from it

I have a pressure/temp gauge right after the air separator/expansion tank, I have temp gauges at the inlet of each supply manifold and exit of each return manifold, so I can get those readings. I do know that for the short times I have had the heater running, I have had full discharge temp...

Tried that and same issue
