Thanks, I appreciate that, and you're very welcome. Regarding the driveway, if I shut it off before the surface is dry, it will re-freeze and create an icy mess. I haven't noticed any spalling, but I also almost always run it until its completely dry. I keep the driveway properly sealed...

Sure thing! Like others have mentioned, you could still do it that way, but you're dealing with 2 different temperatures. A hydronic unit heater will want much higher temps than your floor. My system provides my garage floor with 125º glycol, and turns off when the return reaches 82ºF. No...

Do you have LP available in the shop itself? You could just use a regular gas fired reznor or equivalent unit heater as your supplemental heat and backup. That’s what I do. The radiant slab keeps the garage at 60F all winter. No thermostat for the radiant, I use an aquastat on the return that...

@andyvh1959 Are you referring to my setup?

Correct. The two tankless units are linked, and communicate with each other. They will self-modulate from 15,000 BTU's up to 400,000 BTU's. I've never observed or needed them go higher than maybe 340,000? You are very observant. We spray foamed the entire house as we renovated over the...

@Grogg You're welcome! Glad you found it helpful. It was a lot of work but I'm so glad I decided to do it myself. @86turbodsl Thanks! Fuel Source is Natural Gas. You are correct, it is not "cheap" to run (costs about $0.50 per hour when running), however it's cheaper than a plow service...

Hey @E.rodz I remember finding this thread back in 2010 when I built my garage. It was one of the many threads that led me to insulate and put pex in the slab. That later led me to add pex to the basement slab in 2011 when we re-poured the floor, and staple-up to most of the house as we...

It was a pleasure to have a small hand in this amazing build. Great job with the thread! Although I had the benefit of getting real-time updates as The Willows was being built, I am thoroughly enjoying following along as you demonstrate it in detail for everyone else! Your inspiring me to...

I used 2" rigid foam board (R-10) under all of my radiant slabs (garage and basement). In the garage, the edges are also insulated with 2" foam board that tapers off 45 degrees to the outside edge.

Looking at approximately 7-8 zones, 16 loops total. All loops will be 330', some less but no less than 10%. 6 loops are in-slab (3 garage, 3 basement), the rest are staple-up. Jury is still out on heat source. Original design was using my existing Bosch Tankless with flat plate, however that...

As I design and install my radiant system, I'm curious everyones opinion on zone valves vs zone pumps, and your thoughts on the Grundfos Alphas? My setup will be 100% in-floor radiant, some staple-up, some in concrete (basement, garage floors). My designs originally call for a couple of large...

In the grand scheme of things, PEX is cheap. Download a free trail of loop cad and lay things out. I would definitely take everyones advice and at least put the tubing in. Once that concrete is poured there is no going back. I put the tubing in when I built mine back in 2010, and I am...

Dust Collection

That's the one, thanks blatterjr! I'll stop by and grab one today with that coupon, saves me from going anywhere near that place on Black Friday!

Anyone have a coupon for the 93897 50' air/water hose reel for $59? Bought one a while back and looking for a second. All I have is $64 and $69 ones. Also, anyone have a good $69 or better coupon for the 1/2" earthquake impact wrench (68424/2623)?
