I agree that any foam that is daylight exposed needs to be protected, especially from the daylight.

There is a wall between the two and the floors poured independently. The perimeters of both floors have 2" insulation on them.

You got me thinking about this Firebrick43. If I were to simply put the outdoor loop in parallel with the manifold loops I could simply put a ball valve in to isolate that loop when not needed without the potential hazard of the purge tee being accidentally closed completely. This would give me...

For the DHW part, combi boilers that I found start around 100 Mbtu. The ones I priced were higher in cost than this one. Other options I considered included two separate water heaters for CH/DHW and CH with indirect DHW tank, but this would have been more costly than the one unit. One of the...

Looking for some input and validation of my hydronic heat system planning. Now that my barn has been up for a little while and the floor has been poured with pex circuits installed, I am looking to install the heat. Here are details of the project: Metal clad inside and out pole building...

I had built something similar in the past. It was well insulated above a 12 in. stem wall and I did have a green patch around the exterior all winter long. If I were to do it again I would have used furring strips all the way up the walls above grade with foam panels in between just the height...

In reference to the stat, I see that it is shown to work with HydroSmart controllers/relays. It is probably a matter of having certain settings. A call to HydroSmart should clarify how it is meant to work with their equiptment. I also have a thermal viewer that works with my phone and it quit...

I suspect that the stat that you have is trying to modulate power to control desired temp. For example it is applying 10% power and your system is seeing it as on. Perhaps the hydronic reference was for an electric water heater/boiler to control. For my own setup, I am curios as to what pumps...

I could be wrong, but I believe the Aube TH114-AF-024T t-stat is for electric heat control. I can only find an over simplified user manual for it indicating that it varies its output for heating demands. From what I see, there is no floor only input for floor only. From what I read, the floor...

Just to clarify, use Tyvek between outdoors/insulation and polyethylene between indoors/insulation.

When I had mine built I had wrap installed on the exterior before the exterior metal was installed. This was done to help with moisture movement and more important to me the movement of air within the wall cavity. Just remember that wraps will allow moisture to move in one direction when...

If there is a broken seal between the fluid and atmosphere, then there is a component failure. If fluid flows freely when a bleeder is cracked open, there is a problem. You may or may not get a very small amount initially when opening a bleeder on a properly operating system of modern vehicles...

Something else that has not be mentioned is the state of the foundation. Has there been any settling or movement of the foundation around the problem areas?

This is what I see as well. It is apparent that this was done by someone without knowledge on this type of construction. I believe that a structural engineer that specializes in this type of repair is required. Without proper supporting and bracing, trying to repair the geometry of the framing...

Call and ask POCO what they require when a customer needs to pull a meter. In my area they only ask to be notified when ever the meter has be pulled so the can reinstall a new tamper wire ring. From a safety stand point, if all you are going to do is work in and around that small panel, it would...

Thanks for the replies. I am aware of there purpose and operation. Having done a quick search on them I notice that there are a few different battery types and was uncertain if one would be better then the other or a type to avoid. I envision a scenario of working in the back of the shop on a...

I have been thinking of adding some type of emergency exit lighting to my shop area. Looking for input on what are the better options for this type of lighting, mainly battery type. What should I be looking for in the specs?

Platonic Solid Thank you. I appreciate your help in improving the layout efficiency. I will use the 16'x8' spacing and chain mount as close to the ceiling as possible that still allows easy installation, to limit swaying on windy days (very windy location here). I will follow up with...

Platonic Solid The lift location is locked in due to the provisions in concrete slab, hydronic floor tube routing and the electrical conduit stubbed in the concrete at that location (red circle in pic). I didn't mention the overhead doors located on front of the building that stop 12-15 in...

Platonic Solid, I am considering one alternative general lighting layout that includes an additional light fixture centered in front of the lift, located on the truss closest to the back wall. This would help with working under the hood of a vehicle as well as this is the area where a majority...
