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.

The most helpful radiant floor video I've found. Ty for breaking down each component.

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

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. kzfaq.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh 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).

Great Job! I truly learned a lot about these system installs. Thank you!👍👍

Thanks for the good install guide… looking forward to the cost breakdown.

Very well done. Very informative.

Been waiting for this! Never asked for it but I have been wondering!

I really appreciate this video, i'm planning a radiant flloor in a cabin, really usefull.

Nice clean install! Thanks for sharing the info. 👍

What was the monthly cost to run the electric boiler?

Nice work Paul, very clean system!

Brilliant! Thank you!

Nice neat install Paul.

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!

WHY DO"NT YOU HAVE THE PUMP ON THE RETURN SIDE, SO THE PUMP RUNS COOLER AND LASTS LONGER ?

Great breakdown of everything! Gearing up to get started on mine!

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

Nice video very helpful! This job is identical to mine except I have 3 loops. Are all of the additional fittings and pipe 3/4"?

Great vid and explanation..... Thanks!

I'm getting ready to wire mine up shortly. What did you use for wire for the circ switch control?

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

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 ?

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!)

Nice Job!

will that size boiler work for a 60 x 40 building one zone? If not what size would you recommend?

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

What temp do you have the water set to on the boiler?

Do you have a link to that kit?

I couldn't find an update on how much it costs to run.

Paul, nice job. Did you do the tubing install also?

so if you use glycol it wont freeze?

How many loops do you have. Thanks mate 😊👍

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.

For what it is worth I installed a one zone radiant floor heating system in an area that has a crawl space. The install was very labor intensive working alone and totally NOT worth it in my opinion. It took me over a year to install the system. Best wishes to all homeowners who DYI anyway. Just my two cents.

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.

Looks to complicated. Move to a warmer climate!!! Costs are much lower. This week in Foley,AL was 79 degrees.

10k for infloor heat on 1200sqft. Hmmm

💪💪💪❤❤❤👌👌👌

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

How many BTU and KW/H is that boiler?
