That's a great article Bob. Good Find! .....and that's a fine looking install, Digger. I'm curious though if placing the Spirovents directly before the circulators will have any detrimental effects on the pump.

Good Eye!

I was impressed by that cross-over piece too!

Radiant Chair!?

@ January 18, 2010 1:05 PM in Radiant Chair!?

Well ok, it's not actually functional....but cool to look at!

Filter or not?

@ January 11, 2010 1:07 PM in does it work????

My understanding is that while water softener truly filters the minerals out of the water, this device nuetralizes their magnetic charge and therefore do not accumulate in the piping system/fixtures....am I right here, feel free to correct me!

Yep

Great

@ December 30, 2009 9:59 AM in buffer tank?

That's a great looking install. I'm impressed with the custom tank. I wish some manufacturers would take note and start making smaller buffer tanks. I run into this problem often. A 15gal would be perfect in many circumstances.

P.S.  ....where is the expansion tank in this picture?

What,

would you suggest is an ok pressure, on the high side?

Thanks Bob,

that would be perfect but I shoould have mentioned that I need about 190,000 BTU/h output...

Combo Boiler

@ December 30, 2009 9:08 AM in Combo Boiler

Hello All,
I have someone looking for a High efficiency heating boiler with a stand alone DHW heat exchanger in it (like and instaneous/on demand). I know someone out there has one but I don't know who. I would prefer to go with a Knight and a Indirect but they feel this circumstance requires this "Combo" boiler.

Anyone have any names?

Low flow?

@ December 22, 2009 2:06 PM in Munchkin Contender Heat Exchanger

Would you suspect that low/no flow condtions caused the deformations in the heat exchanger? and if so, wouldn't the high limit kick in before such damage could be caused?

Yep,

@ December 22, 2009 12:53 PM in Fightin' the hammer... (OT)

you're right, the hih pressure has it's benefits. The run outs for all the fixtures are exposed in the basment below. I realized might be a little excessive, but do you think it would be effectiv to put something like a shock-trol on each of those runouts?

Fightin' the hammer... (OT)

@ December 22, 2009 11:57 AM in Fightin' the hammer... (OT)

So let me start out by saying I'm a heating man, I know just enough about domestic plumbing to be dangerous. ...but, anyways...I see to have a water hammer problem at my home. When the dishwasher solenoid valve closes or a faucet turns off, you can sometimes here the pipes knock around in the walls and sometimes the flush valve in downstairs bath runs for a second. I feel like I need to put a hammer arrester in, but it seems to me like those are typically put right at fixture, where my problem is more system wide. There is no backflow device on the house and therefore no expansion tank. The city water pressure averages about 90psi! ...Anyone have any thoughts on the placement of a water hammer arrester.
Thanks!

@ December 22, 2009 11:47 AM in When is Delta T for heating not a true Delta T??

an attitude adjustment....if you don't have anything nice, just don't say anything.
Mark, I recall seeing you display this product at the RPA show last year, It was impressive but it didn't have hot water running through it so I didn't spend much time on it. I'd have to say that this definately deserves some more consideration. Can you direct me to a website where I could study up on it?
Oh, and I'm always glad to see a post by the "Great ME"

Same Hospital!?

@ December 14, 2009 2:34 PM in I'm a Grandpa!

We live in Louisville as well, and just had a daughter in August. The hospital (Baptist East) used the exact same blanket as the one pictured. Maybe I have something in common with a Holohan! ......Anyways, Congratulations!!!

OK,

Well,  thanks again!

Thanks for

the input Dan. Though, I must say that I don't really understand why it is necessary. Doesn't the 67 vent serve as a chamber in itself?

@ December 11, 2009 11:26 AM in Mystery Vent

Went to go look at a job yesterday and while measuring the convectors, I came across this vent arrangement (pictured). It looks like a regular 67 vent with some kind of a chamber under it. Can anyone explain what this is and how it works?
Thanks in advance!

Thank goodness,

I looked at your post before you put the "after" pics up and I thought were saying the "before" pics was the new install that you were proud of! Luckily I saw your second set of pictures, I was about to have to question your skills!.....Good looking job, though!

Thanks BobbyG

You know me all too well....glad you didn't notice the Woodford Reserve stain on my piping drawing! ....That's a real good idea about the tankless heater valves, I'll have to keep that in mind.
Scott K: If I were to change the set up to how you suggest I would lose the ability to operate 3 different temperatures. Each zone is a different type of installation, 1 is a tubing hung in the joist bays, 1 is in a gypcrete over-pour, and 1 is in a aluminum floor tracking system. I might be able too get away with sending the same water temp to the gypcrete and the floor tracking, but the joist tubing will definitely need a higher temperature than would be safe for the other two zones.....that's my thinking anyway, sound right to you?

Assume that customers are reasonable people. Just people that I'll need to reason with.

Cheap Power

@ December 3, 2009 10:57 AM in Conflict over Heat source.

Yep,  the power is cheap. Job is in eastern Kentucky, the coal for the local coal-fired power plant is literally in the backyard. I'm just waiting for the guy to ask me how he can use the waste heat off of his still to heat the house!
