Better option.....

@ February 19, 2012 9:04 PM in Overzealous Water Feeder

The feeder you have has no time delay, no volume adjustment, and is very noisy.  Your water level can end up "stacking" (flooding your system) on you also.  It also draws more juice then a new 24 volt feeder will.  And has more mechanical parts then are found on a later greater model.  There are much better options then the one you have.  Including one a built in water meter.  Give me a call and I'll fill you in.

Ken how is this for a late response......we rarely see them go bad.  But some troublesome jobs have us searching anywhere and everywhere for "mystery" problems.  The few that have gone bad are usually connected to a pigtail that is 100% jammed with crap.  How are your gas bills doing compared to before the repipe?

Even snubbers, and little baby shut-offs......good job!  Did the balance problem work out?

Common venting for mod- con boilers?

@ February 6, 2012 5:40 PM in Common venting for mod- con boilers?

Is it possible to combine venting of multiple mod-con-combi boilers?  They would handle separate spaces in an apartment building.  The building is a historic structure, which makes the venting a tough issue.  Thanks

Combi for long pipe runs?

@ February 6, 2012 5:36 PM in Combi for long pipe runs?

I'm thinking of putting combi's in an apartment building common mechanical room (seperate boilers for each unit).  Not sure if some aprts. that are further away, will get domestic water in a timely manner?  Would a recirc. pump make sense?  Or just go with storage tanks .....or even storage tanks in the aprts. with a pump?  Thanks

@ March 29, 2011 9:52 PM in Combination heating and domestic water boilers?

The job is a historic building.  A total gut-renovation job.  Will be rentals for now, but set up to sell as condos if things ever change.  Close to an urban university and large medical center.  Will draw profs, students, health care workers, etc.

Combination heating and domestic water boilers?

@ March 29, 2011 1:29 PM in Combination heating and domestic water boilers?

I'm looking for ideas on mod-con heating and domestic water combination boilers.  The application is for small condos.  I know NTI makes one.  Just trying to see what options are out there.  Thanks. 

cherry wood and shrinkage

@ March 10, 2011 10:11 AM in gypcrete shrinkage?

Thanks all.  I was also told if the gyp is slightly under I could sand the top of the sleepers.  I think the better contact the better heat transfer?  Even a 1/8" gap is still a gap.....or doesn't it matter that much?
I'm learning there is a American cherry wood and also a Brazilian cherry wood.  Cherry is supposed to be very stable, and one of these is better then the other.  I'm going off information obtained from different sites and also from a MI company Launstein Floors.  They actually test the different woods over radiant, in their test labs.  Check out their web site.

gypcrete shrinkage?

@ March 9, 2011 1:51 PM in gypcrete shrinkage?

I'm installing a thin slab gypcrete pour over tubing.  I am installing 2' x3' sleepers first between the tubing.  Then I was going to put down a 3/8" plywood (cut into 4' x 4's, with a 1/4" gap between sheets and wall edges) on top of the gypcrete.  Then finish with a 3/8" quartersawn cherry wood floor (5" wide).  Does anyone have any suggestions on how to avoid any shrinkage from the gypcrete?  I believe it will be a Maxon product.   

Shrinkage?

@ March 9, 2011 1:44 PM in Optimum sleeper witdhs?

I was going to cut the 4' x 8' plywood in half.  I was told to leave a 1/4" gap at all edges, and between all 4' x 4' sheets.  While time consuming I was going to mark on the top of the wood exactly where the sleepers are under the plywood.  Then screw and probably glue down.  The finish 3/8" floor (quartersawn cherry) would nail down to the plywood with 1" brads, on a 45 degree angle.  Sound OK?
As far as the shrinkage.....you are scaring me.  I will definitely do more investigating on this.  I believe it is a Maxon product.  I don't know why it would take 6 years to shrink?  I would think if it's going to shrink, that would happen withen a year?  Any one else have any experience with gypcret shrinking in a radiant pour?    

tube spacing

@ March 5, 2011 12:47 PM in Optimum sleeper witdhs?

Thanks!  However I guess I misspoke, my job is on top of the sub-floor, with sleepers, in a 1-1/2" gypcrete pour, then 1/4" plywood, and  3/8" cherry on top.  I was planning on supplying the outside walls first with 6" on center for a couple of loops.  If I were to go less then 9" centers with wirsbo-uponor, 1/2" hePEX plus.......what would be the optimum spacing distance?     Thanks again for your expertise, and time.

1/2" tube spacing?

@ March 4, 2011 11:58 AM in Optimum sleeper witdhs?

I already have the 1/2" tubing.  It was recommended that I run 9" centers (by the manufacture).  However I keep hearing 8".  I am a bit undecided which to use at this point.  Any suggestions or opinions on this subject?  I'm building an addition, two stories, over a crawl space.  Staple down with sleepers, then pouring light-weight gypcrete, then I was going to put down 3/8" ply, then 3/8' hardwood (cherry 5" wide) on top.  Insulate under both floors also.   Another question using 2" x 3" sleepers..... you loose a bit of gypcrete surface......will I notice.

Optimum sleeper witdhs?

@ March 3, 2011 9:27 PM in Optimum sleeper witdhs?

I've read different opinions on the best way to install sleepers for a thin slab under a hardwood floor job.  Any opinions on 2" x 2"s vs 2"x 3"s?   I'm leaning towards a 3/8" cherry quartersawn x 4" finish floor, over a 3/8" sub-floor, over the gypcrete.  Any thoughts?  Also is a expansion edge (expansion joint?) required?  Thanks for any feedback, or tips.  I do lot's of steam and hot water heat, but very little radiant.  This is my own residence, so I want to do it "top of the line", and use it to help sell radiant.   Thanks

Do pressuretrols on small residential stem boilers fail very often?
