The black iron (carbon steel) piping coming out of the boiler connecting to the copper manifold should of been connected with a dielectric union. There’s a very good chance that threaded connection is going to experience galvanic corrosion. At the very least, replace that small steel nipple with a brass nipple. Brass is a natural dielectric waterway between two dissimilar metals. Also, on your spigot fill and drain valves, buy threaded caps as a safety just in case someone were to accident open one. Kind of like a lockout tag out. Cheap insurance.
@@jaxchristian6408galvanic corrosion can still happen in glycol system. Standard practice to use dielectric unions or to run a length of brass between black iron and copper.
Very clean looking and simple install. The electric boiler you used has a nice compact footprint and I can definitely appreciate the simplicity that comes with electric over gas for something like this. Curious what the difference in operating cost would be on a small gas boiler vs this. Thanks for sharing!
The efficiency rage is to put something like a hybrid water heater in there to save operating money. It works well as long as the unit works. Its nice to see someone going through the steps as a novice..and gets it done. I learn more from your type of presentation than the manufacturer's rep banging out information.
Replace the black iron nipple that connects to the copper with a 6" brass nipple or make the transition with a dielectric union. Fantastic job though!!
This was an exact replacement for the old one that lasted about 10 years. th-cam.com/users/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).
Got a part number for that dual thermometer you're using to measure supply & return Temp? One suggestion: do counterflow. IF both your supply & return are on the right end of a manifolds, the circuit on the right will have far more flow than the one to the left & so on, due to having the most pressure difference. If you put the supply & returns on opposite ends of the manifolds, you'll have equal pressure difference feeding every circuit. I'll be modelling my setup after yours, with the exception of using a variable speed pump with a modulating electric water heater.
I'll be using this type of system on my 40 deep by 56 wide shop with an attached apartment that I'm designing right now. The shop will be 40x40 and the apartment will be 26x40. It will be a one bed one bath with a half loft upstairs that can be another bed and possible bath. Question; what size of utility room do I need for the radiant floor equipment, an electrical sub panel and a tankless water heater for the household water? I think that's all that I would put in that room. Thanks!
Great video! Do you have a parts list with mfg part numbers, of the parts you bought from radiant tec? I want to build the same exact system except I'm going to use a smaller electro industries 7kw mini boiler, as my basement is 24x36. I would buy all the same components as u did, minus the manifolds i already bought from Upnor, because that was the tubing i used. Thanks
Is there any heat exchanged from the supply and return pipes being close to each other? Is the slab in that area warmer because of all the supply lines ?
hi I have a separate question. I am planning a 35 x 40 post and frame building for my small plane. ideally id like to have one type of roll up door with panes for light but this door needs to be 35 feet wide . can you recommend a door company that can help me pick a door system,? love your content. thx
@@gentzrayamcclellan6401 So again, not the same. This $5000 system does not include any foam or tubing. Unless you're in LA, there's no chance anybody is charging $38,000 for a 1200 sq ft radiant heating system with a 9kw electric boiler.
@@Darnellp87 Ah ok! I know that foam is expensive! We in Portland Oregon actually prices for anything labor seem to have doubled over the last few years
Wish there was a video like this to watch when I was designing my system, very straightforward explanation! Any benefits to the temp probes/thermostat vs tridicator gauges plumbed in? (I guess a temp probe can't leak!)
Comes down to cost and installation. I believe the Azel two zone temperature gauge with sensors is $50. Gauges would be more expensive and longer installation.
Nice... always a pleasure & well done. I'm embarking on this journey as I write this. Question: Why not a tankless hot water heater on your builds & circulation pump(s) instead of very expensive boilers? Thx
I think an electrical tankless for a big zone like this is more expensive, like 800 $ And we are talking about a cheap one., So the boiler come at a very ggod price : a an electrical boiler of this type can live more than 20 years and worked well.
Yah, black gas pipe should have never been used in a hydronic system! Like the previous user mentioned dielectric fittings should have been used at the boiler, but with copper pipe. Glycol is corrosive to mild steel.
Roughly $5000 for controls and Pex if you install yourself. If your including vapor barrier and insulation, because of our climate zone, those need to be installed anyway.
@@MrPostFrame I dont think thats bad for the most comfortable heating method. I have it in my garage...and house. Your cars will have no snow on underside 1 hour after you drive in. The other GREAT feature. Get the garage to say 60 degrees. Open all the doors for 30 minutes...it will be freezing cold inside. Close the doors and in 20 minutes its 60.. Water dries, snow melts, its silent, no highs and lows. COMFORT is #1
I know Paul means well but this is not a good install and will have multiple issues. This is a perfect example of why we need 5 year union and non union trade schools
I Watched on fast forward. Putting sheet metal in front of pipes work even better. Or You can also make up an element using alloy flashing just silicone it in. You fold the flashing around a pipe and it sort of gives the pipe wings which transfers the heat. Hard to explain without a drawing. So the pipe ends up in the middle like a big saddle. You can even see those wings to the under floor for floor heating in your second story.

Great job and very clear description for diy. Kudos for an update on the maintenance cost
Thanks! 👍

What was the monthly cost to run the electric boiler?

Nice neat install Paul.
Nice clean install! Thanks for sharing the info. 👍
Brilliant! Thank you!
Great vid! Any updates on monthly cost?
I really appreciate this video, i'm planning a radiant flloor in a cabin, really usefull.
Nice work Paul, very clean system!
Thanks!

Nice installation, Paul. Looks like a good new partnership.
Thanks, Dirk!

I just got a quote for the same System …38,000 yes 38k how are you doing it for under 5000??

Correct. But it’s heavier than water so it’ll use more energy to move through the tubing
@@MrPostFramedid you ever get a running cost per month or year
I couldn't find an update on how much it costs to run.
Paul, nice job. Did you do the tubing install also?
Yes
