A five-winters update on this. This boiler has just plain worked with no fuss and that was the whole point. This winter we've had some uncommonly cold multiple day spells in the single/below zero temps. I noticed the boiler not quite keeping up and running constantly all day with the shop...

No, that black "tank" you can see is the boiler part. There's also an expansion tank built in to the unit behind that. You can't see it from the front.

It definitely has a built-in expansion tank, but I'm not sure about a pump output relay. I remember reading something about being able to add an external pump, but I just use the internal pump. Thanks for the info on the temp setting. I'll turn it down a bit and see how it does.

The heating element runs on a 240VAC circuit and requires no neutral just the two hots and a ground. The circulating pump, however, runs on a separate 120VAC circuit and requires a netural. I wired up a pigtail with a standard plug for the pump and plugged it into a nearby outlet.

Feel free to post to this thread, and I'll chime in if I'm around. Sometimes I go a week or two without logging onto the forums if I'm traveling or busy.

I got the 8KW unit. I ran a bunch of calcs for heatloss to come to that number. I used a calculator similar to this one: https://www.builditsolar.com/References/Calculators/HeatLoss/HeatLoss.htm I can't remember if that was the specific one I used, but it was very detailed like that to get an...

This boiler worked perfectly through last winter. I finished my insulation and was surprised how comfortable the shop was in our high desert cold. I've just recently fired it back up for this winter and all it took was turning it back on, and waiting a day for the slab to come up to temp. So...

Can you post a model or link to the switch you bought? Is it z-wave?

This isn't a solution for you, but this is what you are fighting: https://www.ametherm.com/blog/inrush-current/inrush-current-protection-led-lighting-retrofits/ There are options, none of them easy. I ran into the same problem with my smart switch plans. I gave up and put in old-fashioned...

Thanks, Justin :)

I recently did this upgrade at my house. Electrician drove two new ground rods and the inspector checked to ensure they were there, too. I didn't discuss why he did it, though. I can't comment on the rest of your questions, since my service comes in through an outside meter base separate from...

This is all great information. I have some more studying to do. For the record, I bought these, which I'm assuming are using junk drivers since their price point is on the low side. I asked the vendor what their inrush current is and have not gotten a response yet. Not holding my breath...

I'm in the final stages of my shop build and putting up my lights. The shop is a 42x24, 18' ceiling at the highest, and I have six 160W high bay LEDs and four 100W high bay LEDs in a lower area. These are split on two 15A circuits (four 160W/two 100W and two 160W/two 100W). These loads are...

I'm in the process of building a 24'x42' detached shop. I finally got my electrical rough-in inspection passed and have started on insulation. The plan for heat was always in-floor radiant and up until recently I was undecided on the boiler setup. We put 1/2" pex tubes in the slab. I don't...

Our local inspector wanted to see 50psi in my pex tubing. It held that fine for several days while I waited for inspection. I also kept it pressurized during the pour and watched the gauge to see if the concrete guys accidentally damaged anything.
