I Understand

@ April 19, 2014 2:52 PM in 270 Ft Manifold

I just seem to get bit by Mr. Murphy whenever I do stuff like that :)

Rob

Nice Job!

@ April 19, 2014 2:30 PM in 270 Ft Manifold

The only thing that would scare me is having that many connections under the slab. Could the manifolds have been elevated and installed in the wall? Beautiful workmanship!

Rob

Wow!!!

@ April 19, 2014 2:03 PM in CPVC in hydronic heating system

I agree Superdave, time for a re-pipe. I love the idea of not using any of those pesky isolation valves however, it really helps on improving flow rates of the system.

It's interesting on Wayne's post from Charlotte pipe, They start out saying that Flowguard Gold CPVC in cts size is okay for hydronic, then at the end say only SCH80 should be used. That makes no sense as cts and SCH80 are two completely different animals. And we wonder how jobs like this get installed, much less approved. It doesn't look like they even  used the Flowguard gold cement.Go figure!!

Oil Base

@ April 18, 2014 12:42 PM in Painting Cast Iron Baseboard Radiator – Baseray/Governale

As well, with oil base paint your house will smell awful and probably off-gas when heated.

@ April 17, 2014 1:21 PM in pressure relief valve

With the system empty or the tank removed, the pressure in the tank should be set to the fill pressure of the system. If you only have twelve pounds in the tank and the fill pressure of the system is twenty, you are not leaving a whole lot of room in the tank for expansion. How many floors is the house and where is the boiler located? This will determine what the system pressure should be.

Thanks

Thanks for the replies, I will use it as a tool, not a sales tool. I don't have the time nor interest to do blower door tests (I'll leave that to you BPI boys). I know I'm behind the pack on getting one but I have held off, call me cheap but it has always seems that when I am walking out of the store with the newest gadget a delivery guy is rolling in a handcart of newer, cheaper, better gadgets.

Thanks,
Rob

Great Advice

@ April 17, 2014 11:37 AM in Need advice/ help for new heating system

You have been given some great advice, keep the hot water system and get a true radiant heating proffesional in to de-bug the system. I would bet money that the system is not nearly as screwey as you are being told. Could you post some pictures of the boiler and the associated piping? If we can "see" the system we can point you in the right direction with eyes wide open. Coming to this site for help was the best money you never spent :)

Coal boiler

@ April 16, 2014 3:53 PM in Modifications to Hydronic System

Is this a closed or open system? Did you use oxygen barrier pex for the radiant?

Entran

@ April 16, 2014 3:49 PM in The dreaded Entran

You said it's still pliable, the stuff that was plugging it was probably a biological growth. Did it stink when the system was first opened up? I would go with the heat exchanger (I would still use an oxygen inhibitor on the Entran side just for extending the life of the tubing).

Thermal Imaging

@ April 16, 2014 3:36 PM in Thermal Imaging

I'm thinking about getting a IR camera. One of my questions is if they work for identifying air infiltration / exfiltration areas to aid in sealing homes. If it would work, I was thinking about using it as a sales tool " Using IR camera, identify and seal and / or notify homeowner of areas of visible infiltration".  If it can be used for this, what would be the best way of doing it, indoors / outdoors, day / night?

Just brainstorming

Thanks for any input,

Hot Water

@ April 16, 2014 3:10 PM in losing heat

The easiest test, just turn on a hot water faucet and walk over to the water heater and grab the hot water outlet pipe, if it's hot enough, you'll know it. Another thing to look at is any two handle faucet that may have the handles open (I have seen a hose attached to the laundry tub faucet with a sprayer on it, the faucet handles were left open and the water would travel from the cold into the hot side tempering the hot water. It could however be a bad thermostat in the gas valve.

Piping

@ April 16, 2014 2:22 PM in Modifications to Hydronic System

I think that this is kind of what you are trying to do (see page 43 of attached manual). This is for a completely different boiler than you are using, but it illustrates the piping of a system with mixing valves and closely spaced tees and an indirect. You will have to size you pumps based on your cv's, loop lengths etc....

Entran

@ April 16, 2014 1:47 PM in The dreaded Entran

Is the Entran used for a separate radiant zone from the the cast iron rads or is it run to the cast iron rads as a piping replacement? If it is a separate zone you should use a heat exchanger and non-ferrous components for that zone. If it is run to the rads use an oxygen inhibitor. Contact Rhomar for the correct product. As well, let the customer know that the chemical treatment needs to be maintained annually. This is the best solution barring a re-pipe.

Recipes

@ April 13, 2014 6:13 PM in But he's SO cute

However there are several fine recipes for cooking them. Squirrel pie being my favorite. MMMMMMMM Yummy!!! 

Absolutely

@ April 5, 2014 6:03 PM in Indirect or Combo Boiler with Recirc DHT?

As Snowmelt said. Terry, just go to the Navian site and they will tell you exactly what you want to hear. I for one always trust manufacturers claims : ).  

If it were me, I would go with the indirect and the recirc and be done with it.

JMHO,

The Problem

@ April 5, 2014 1:41 PM in Problems with Open radiant floor system

This is the problem with the Internet peddlers / designers. For the cost difference of the two additional stainless pumps, you could have installed three cast iron pumps, a flat plate heat exchanger and actually saved money and had a safe and functional system. Do you have o2 barrier tubing installed?

Do you warn family and guests about the questionable water at your home?

Step over a dollar to pick up a penny.

Paul, are you seeing stinkbugs and ladybugs on the west coast?

Rob

Painted?

@ April 4, 2014 2:25 PM in Bad hydronic panel install...

It almost looks like the pipes might be painted silver. I can't quite tell. It's hard to believe that there is not one black fitting or support in there. I hope thats what it is, for his sake.

Rob

Paul is right

@ April 3, 2014 3:41 PM in Need used or cheap commercial steam boiler

George, perhaps if you post the non-profits cause you might get a more positive response. Used boilers are usually relegated to scrap. If it is for a good cause people will keep their eyes and ears open. Who knows, rather than having to buy it, someone would probably donate it. A quote that I recently read struck home with me. "What I regret most in my life are failures of kindness"

Stinkbugs

@ April 3, 2014 1:55 PM in Stinkbugs

I'm just trying to find out the geographic areas affected by stinkbugs. For the last five years give or take ladybugs have gotten horrible in my area (Winchester, Va), they get into air inlets, combustion chambers, you name it they're in it. But for the last three or so years stinkbugs have entered the equation and multiplied the problem, They cause problems you wouldn't anticipate, I found a stinkbug in between the contacts on a relay the other day. How far across the country is this an issue? Or do you have other critters?

Steam / Hot water

@ April 3, 2014 11:53 AM in Value of converting oil/steam to modcon gas?

If no insulation upgrades have been done to the house, you very possibly will not be able to re-use your existing radiators. The radiators in your home were sized for steam heat which operates at a significantly higher temperature than hot water. If you were to switch to hot water you shouldn't be surprised to be cold on cold days. As well, not all steam radiators are capable of being converted to use hot water. Why not vent a new gas steam boiler through the wall?
