Wow!!!

@ June 28, 2014 4:25 PM in Poor radiant floor hydronic installation

Your instincts are correct grasshopper. I am going to save that photo to show to customers while bidding jobs. I cannot say that I have seen something so, so, I don't know what to say. I hope you can get it re-done, but by a different contractor (I can't see how that one even has a license). It looks like the T&P and the pressure relief valve are piped directly to one another? Can't say that I've seen that one before, and I've seen allot of hack jobs. I would not even consider running that system in its current state. Why ruin a decent boiler?

The more I look the more depressing it is. As far as I can follow the spaghetti, it looks like the expansion tank is being used for both domestic and heating, no gas cock. If your builder won't have it redone, it would be lawsuit time in my book.

Whenever I deal with an issue that Is not covered in the installation manual I always try to cover my but as best I can. If an engineer from the factory told you something, just have him put it in an e-mail so that if an inspector asks or a warranty issue comes up you have it covered.

Insulating

@ June 22, 2014 3:03 PM in TT Smart 80 & Prestige Solo 110 Summer Gas Usage

Just trim the foam around what you have to work with. There is no science to it, just do the best that you can and it will be fine. The aquastat has an enclosed bulb so once again just get it as well insulated as you can. As someone said earlier in the thread " you are using a little energy to save allot of energy". In an ideal world whomever built the home should have had the lines insulated prior to closing in the walls. Post some pictures of the rest of the system and we'll see if there are any other modifications that can be done to improve the system efficiency / operation.

Ice, the picture is 90 degrees off. If you look at the boiler photo you can see the electrical box on the upper left.

See

@ June 21, 2014 4:40 PM in TT Smart 80 & Prestige Solo 110 Summer Gas Usage

See my edit above. You won't get it perfect, but just as close to perfect is good enough.

Lools good

@ June 21, 2014 4:30 PM in TT Smart 80 & Prestige Solo 110 Summer Gas Usage

That looks just fine. Insulate everything you can get to. Even the drain side, hot goes to cold, that is the reason for the insulation. What is it, another six inches? 

As for the mounting brackets just trim it as best you can. Cut a couple of holes for the wings on the brackets and face the seam toward the wall.

Sure it does

@ June 21, 2014 2:27 PM in TT Smart 80 & Prestige Solo 110 Summer Gas Usage

Sure it does, if you have a mixing valve. Have a look at this drawing from a couple of posts back.

I can't get the picture to copy but look at drawing one from hot Rod on the post "recirculation loop" (It should be two posts down in this forum).

Tankless

@ June 21, 2014 1:30 PM in turn down boiler in summer when I only need hot water?

I also have had Ice's experiance with tankless coils. Now if you are talking about an indirect water heater the outside of the coil will get crudded up. It's the introduction of fresh water that calcifies. No boiler leaks=no calcification


JMHO,

Exactly

@ June 20, 2014 1:54 PM in TT Smart 80 & Prestige Solo 110 Summer Gas Usage

Exactly, the only time you are putting "cold" water into the tank is when you are using hot water. When circulating it is just displacing enough of the 140 to make the bring the 110 back up to 120.

It's tough to descibe but I think you've got it.

I'm not

@ June 20, 2014 12:56 PM in TT Smart 80 & Prestige Solo 110 Summer Gas Usage

I'm not sure you are fully grasping what Charlie and Carl are saying. When you are putting out 120 deg water and bringing back 110 deg, the majority of the 110 deg water bypasses the tank and goes back into the cold side of the mixing valve. As the mixing valve is putting out 120, just a tad of the return water goes into the tank and just a tad of the 140 water leaves the tank into the hot side of the mixing valve to create 120 on the outlet of the mixing valve.

I don't know if I made any sense whatsoever :-)

I guess

@ June 19, 2014 6:08 PM in Hoffman Boiler Feed, persistent trickle feed and overflow

I just don't see how it could be installed without access. If it was able to swivel when installed it could turn instead of going up to shut of the water? It has to be stationary, but to be stationary it would have to spin in a circle to get screwed in and would hit the side of the tank. Am I dense? 

Does it

@ June 19, 2014 5:02 PM in Hoffman Boiler Feed, persistent trickle feed and overflow

Does it swivel at the plunger when you install it? How do you set the water level or tighten the wing nut

Tapping

@ June 19, 2014 4:43 PM in CI Rad, intlet & outlet setup - Bushings, nipples, elbows and TRV’s

I would follow HR's advice and drill and tap for one size larger and be done with it. You could probably do them all in a couple of hours. They are rather unique so I would defiantly keep them. If you really wanted to get elaborate you could braze a piece of copper into one of the lines and extend it into the rad to promote a more even flow through the radiator.

JMHO,

Relief Valve

@ June 19, 2014 3:30 PM in Can the boiler be the air scoop?

Is there a relief valve on that thing? If it's on that pipe going back to the left it should NOT have a valve on it. Was it taken off to install that float vent?

Rob

I hope

@ June 19, 2014 2:52 PM in concentric termination relative to dryer vent

I hope you knew I was being sarcastic, lint free clothes? Concentric vent, shrubs? In the words of ME "I'll be here all week"

Tank

@ June 19, 2014 2:19 PM in Hoffman Boiler Feed, persistent trickle feed and overflow

I am no expert on condensate receivers but there is no way that valve in the picture is the one in the tank unless there is an access hole elsewhere. There is no way for it to thread in with the float attached.

The Math

@ June 18, 2014 4:21 PM in 95% Efficient Condensing Replacement Boiler

The math doesn't lie! That is why delta t is entered into the equation.

Lint

@ June 18, 2014 2:16 PM in concentric termination relative to dryer vent

Ice, obviously you don't buy the "lint free" clothing like everybody else in the world. You must get the stuff made in India or China.

It sounds like the "Perfect Storm", dryer vent, concentric vent and a few well placed shrubs to hide them all.

Wow

@ June 18, 2014 1:25 PM in Made in America

I love photos of the past. My favorite of that collection is the guy working on a bridge? Skyscraper? He's on a scaffold made of wood, cantilevered out and god knows how many stories up. He probably ate his lunch sitting in the same spot and admiring the view while discussing the baseball game that was on the radio the evening before. Men of that era had balls of steel and wondrous imaginations. I still love listening to the stories of the WW II vets at the VA hospital.

God Bless,

Rob

I agree Rich

@ June 17, 2014 4:03 PM in 95% Efficient Condensing Replacement Boiler

I agree Rich. Gas pipe sizing is based on pressure drop, specific gravity and supply pressure. That said, it is not fair to tell someone that they can automatically use 15' of 1/2" piping for 180,000 btu's. That is just as reckless as not recommending a heatloss and just pulling a boiler selection out of your *** because you're to lazy or inexperienced to do the heatloss. Manufacturers can state whatever they want, but I don't believe everything that I read either.

But

@ June 17, 2014 2:55 PM in foam in oil feed, even with tiger loop

The real question is, have you gotten a tan yet?
