Magnetic?

@ February 5, 2014 1:44 PM in Triangle Tube Excellence condensate trap sediment

Have you tried a magnet on it?

Edit: I re-read and see the answer.

That is about the same quantity of debris produced by each of my two NY Thermal Ti200c boilers in two years, combis also. The debris in my case is magnetic.

FRP Slipped Behind Piping

@ January 26, 2014 8:37 PM in System Running. I am extremely grateful!

I like that kind of plan. Also possible is to get a piece of doorskin ply from a lumberyard; it's about 1/8" thick and you can pick many species of face veneer.

take care of the dhw supply temp and set the dhw control value to 140 or higher. That way your mixing valve will produce stable hot temps. You may quit condensing at that time, but have a happier crew in the house.

Maybe call fluke & see if this is intended for that task.

Here is an air to water system that claims to produce up 130f water:

Somebody on here heats their shop with one, wish i could remember who.

Warmboard

@ December 9, 2013 10:48 PM in Radiant Floor Heating in Modular House

I looked into warmboard about 5 yrs. ago for a client in a five unit project. The biggest benefit for mild climate western Washington was that it's heat capacity was much less than standard concrete, which was the other option. What that meant was that it would be more responsive to outdoor temp changes and tend to overshoot less than a high heat-capacity slab. Cost drove the client back to slab on grade and staple up with plates in upper floors.

Purely from a building assembly perspective, warmboard requires careful shop drawing layout and quality control so the tubing doesn't have to be run under partitions, etc. the tubing remains at some danger from nails and screws for quite a while in construction, but I was doing stick - built.

It is expensive.

@ December 9, 2013 10:24 PM in New install: choose propane or oil?

Towards one propane tank with separate metering so you bulk fill the tank and sell them the gas. LPG I think is mostly made out of NG these days, so some price stability can be expected out to the future. Plus, you then control whether fuel is available in empty units during turnover. Meters are available with web- based monitoring if you are three towns over. You could run gas ranges through the same meter and capture the "I like cooking with gas" crowd. I have three rentals and the gas ranges are still appreciated in spite of the induction range crowd pointing out that they are fine machines also.

The LP tanks can be buried or above ground, and outside, so no loss of useable building sq. footage.

@ December 6, 2013 11:40 PM in Munchkin T80 - Maintenance questions

the donor take-out boiler be? HTP doesn't apparently make the T80 anymore, so some consumables may be easy to find in the future, but maybe not the big stuff.

If you are hands -on you could learn to do annual maint. yourself pretty easily. I taught myself on a couple NTi boilers I have, it takes me about 2.5 hrs to do the pair of them annually.  If I get in a jam I have some names of people familiar with them.
Combustion testers are for sale as well. Or ask around for a pro who has experience with that boiler. There should be quite a few in the Seattle metro area.

@ November 22, 2013 8:39 PM in Altherma

Wondering what the thinking lately is on the Daikin Altherma [or equal other brand] in terms of service cost and suitability in residences. They have been out for 3 -4 years at this point I think.

I don't hear much about them in the Pac. northwest, maybe they are generally too costly or just got eclipsed by ductless equipment.

@ November 12, 2013 8:33 PM in Quality of help on the Wall

I also spent 28 yrs. as a builder [gc, retired recently] similar to the first poster. In my view there is a large concentration of talent and generosity here. I have also had the frequent frustration of having to say to the naive questions over the years that the answer is to hire a pro. That answer is appropriate when the asker is so deep in never-never land that the detail would take fourteen single spaced pages to properly treat. Who has the time? They would likely not get it anyway. In most schools you pay tuition.

 Other amatuers  try hard to school themselves and deserve some detail and help.

You guys play in a field that is so technical and experienced based that my guess is fewer than 10% of bad installs asked about here actually get wrenches put on by owners. They likely just spend the money all over again, hopefully on something that works.

Review your lease

@ November 12, 2013 7:11 PM in the maintence office person came again

Maybe get with your atty. or legal aid and approach it that way. Management are denying there is a problem and are portraying you as a nutty complainer.

How do your neighbors feel about the noise?

Nice

@ November 8, 2013 8:20 PM in Solar Thermal in Seattle

Good looking job, and looks like lots of room in the mechanical space. Were you responsible for the structural steel, or the gc?

Funny how "instrumentation" has lately become "dashboarding" in the green business.

Clr

@ November 7, 2013 3:20 PM in Knight boiler problems

As Mark pointed out, using CLR or similar helps cut the hardened crud. A spraybottle of Lime-away is about $6 from a drugstore and is enough to clean 2-3 small boilers.

What type of camera did you use?

carcin

@ October 30, 2013 10:15 AM in Knight boiler problems

The material looks to be the same stuff that shows up in boilers using that hx, just more than usual.

What info. do you have about it being "carcinogenic"?

Alternative to water

@ October 28, 2013 11:52 PM in The Blessed Technology of Fracking . . .

There is an alberta co:

http://www.gasfrac.com/

That uses gelled propane as the hydro fluid. Once the grit is pushed into the fissures, the gel then gassifies and is extracted with the ng payload. It was developed in the 40's iirc.

In popular parlance the term "fracking" seems to signify anything objectionable having to do with petro drilling, so even if the aquifer problems were put to bed, I think it would still be a four letter word.

dhw tank

@ April 26, 2012 8:49 PM in Navien Combi opinions wanted

@SWEI,

You responded to Bay areaDIY:

"Using a DHW heater (tank or tankless) for space heat will not get the
job done well, will not be covered by a warranty, and will leave you and
your family open to Legionella infection."

He was suggesting an hx to separate dwh from heat. I the case he is refering to, wouldn't a conventional tank be ok if he was willing to ignore the warranty? If he later adds 500sf as he mentions, then a better heat plant might be substituted.

Well, maybe not condoning, but he characterizes deviating from written specifications as the only rational path because everyone else is so bent up. We are talking about plan-spec work here, right? Not a case where a mech. contractor is hired and given carte blanche to deliver the best job they know how, or straight design-build?


Then he says:

"General contractors certainly aren't going to make sure their subs do
their work by the letter of the law. GCs are more concerned with getting
the job done quickly and getting out of there."


The general may not police subs at a detailed technical level, because they usu. do not have that specific expertise. But when have you  seen a subcontract that did not insist on faithful execution of the documents? Let's not assume that subs can't read drawings...the general shouldn't have to tell the sub how to do the job, only that they do it correctly.

As far as making a sub or anybody else responsible for rooting out errors and omissions in designs and documents that others provide, strike it out, it's unenforcible. You can't be called out for not noticing an error, but you do have a human obligation to speak up if you see something wrong. That issue was put to bed in a 1918 federal case: http://en.wikipedia.org/wiki/United_States_v._Spearin

I think the writer is being irresponsible, but I'm going to quit here before you guys all decide i'm nuts...

Huh?

"Contractors Do Whatever They Want"

This guy is a "contractor's business coach"?  I hope he goes broke if he condones the kind of crap he layed out there.

While he is correct that documents are in a sad state, that does not give a pass to mechanical or other trades simply doing what they want. In lots of commercial contracting, if you change the plans or specifications, you are then assume liability for the design as well. If I find a conflict or see instructions I know will not work, I call or email [electronic record if you need it], text or whatever the design team and point it out. Sure, recommend a better way, but just don't change something without that communication.

Nobody's looking? sure, lets all do whatever we want then!  That's just plain condescending and offensive. I wonder how far he'd get in the local beer joint with that story.

Sorry for the rant, this kind of stuff twists my tail.
