December 23rd ... 65 degrees ... It's a great day in the Green Bottle Bar !!

I agree with Finn. Adding antifreeze inherently reduces the efficiency of the system and increases the load on components. There's no metal tubing or copper pipe in the system, so no worries about corrosion. The only moving parts are the submersible pumps (inexpensive and readily available)...

I final finished up my ceiling and insulation, as it was a little tricky transitioning from the loft area to the cathedral ceiling. Amazing how much difference the last 5% of the job made. Since finishing the temp has gone up 10 degrees on both the garage and the pool house side. It’s hard to...

Yeah, I understand. I had already run a 60 amp circuit and looped the line above the brand new ceiling. By that point, it would’ve been way too much work to backtrack.

We discussed that as well, but I suspect the climate here is different enough that it was a toss-up for central Indiana. Also, I was limited in the size of water heater, because of the electric I already had in place, so wanted to be as efficient as possible.

Yes. Distilled water will transfer more heat than an antifreeze mix, and I'm not too concerned about the system freezing. It would have to be a bad chain of events to create any of those problems for me.

Bams - good to hear. Hope you'll be as pleased as I am. The installation instructions were very specific and clear. Adjusting the little jumper pins was new to me, but once I understood the circuit board it was easy. I had two small glitches, both easily resolved: First, the pump for my...

Bams - I'm happy to help. The system has been connected and running for about six weeks now, and I'm 100% happy with it. The company has a youtube channel with several videos, and it was as easy to hook up as the videos show. https://www.youtube.com/@HUGHydronics I'm in Indianapolis, and so...

Just got back from a week in Florida -- left 84 degrees and returned to snow, but my garage was toasty warm. So far, the HUG system is working flawlessly. Very happy with it.

I finally got my new HUG Hydronics system installed last weekend I had a couple glitches to work out this weekend, and Everything is now up and running perfectly. Here are a couple pics. For reference, that black wallboard behind it is 44”W x 48”H. I have two zones arranged, with one loop...

I installed my new system last weekend, but had a couple glitches to work out this weekend. Everything is now up and running perfectly. Here are a couple pics. For reference, that black wallboard behind it is 44”W x 48”H. I have two zones arranged, with one loop feeding the kitchen side and two...

HogDude - I've seen your posts and appreciate your profile pic. My wife was tired of me sitting on the front porch with my legs in a sleeping bag, so she was fully supportive of heating this place and adding exhaust fans. She used to hate my cigars, but now she's good so long as there's...

Good advice. And it appears that similar pumps are readily available, so should be pretty easy to source.

Like I said, if I can sit out there, have friends over, and smoke a few cigars in January, I'd pay $98/week! The building is on its own electrical service, so once it gets cold, I'll report back.

Firebrick - I’m not going to argue with you. I don’t know how the system puts those stickers on the boxes, but they’re on every appliance you buy these days. I’m heating a 1000 sq ft garage, very well insulated, to 50-60 degrees in Indiana. If I can sit out here and smoke cigars or do an oil...

Yes - any heat source would work, but I didn’t bring gas to this building, so it’s a tankless electric. The sticker on the box projects $98 annual costs, and with this use, and for only about four months, it should be significantly less.

Firebrick - I’m inclined to disagree, but time will tell. The pumps are easily accessible and can be swapped out in minutes. Other than the internals of a $300 water heater (no boiler, no heat exchanger, no valves, no manifolds, no fittings, no pressure tank or relief) there’s nothing to...

Hi Fitter - my loops are pretty standard - 1/2” Pex with each loop between 250’ and 300’. My building is 1050 sq ft inside so spacing was about 15 inches. Two loops will be in the garage side with one on the pool house. Each side with its own thermostat. Not sure of pump brands but the three...

About the screen -- I worked with the guys from The Perfect Pergola in Indianapolis. The screen system is called Magna Track. I talked with them first at the Indy Home Show, and they were great to work with. There were three or four groups at the home show with similar systems, but Perfect...

I never got much reply on this, which makes sense as I don't think anyone has much experience with these systems. According to their social media, they just shipped their 500th system a few months ago, so now it's at least 501. I pulled the trigger and my system just arrived today (within a...
