yes, the vacuum breaker is required by code (something to do with tank design) and recommended by Amtrol. The tigerloop goes on all our boilers. No air bubbles stopping a boiler while the owners are on vacation in February! Normally we use the OV Combo that has a built in filter, but we were out of stock so we stuck the standard on with a regular filter.

Very well thought out work. Very neat and clean.

The vacuum breaker stops the tank from colapsing if there is a negative draw on the tank ( fire hydrant being open is the best example ). If there was no Vacuum breaker the tank could colapse. Its code in Mass.

Again nicely done.

this looks awesome. What is the beige box next to the zone valve controller?

Nice looking job

May I ask why in many of the photos seen of completed jobs, the pipes are not over wrapped with insulation? Of course I am assuming that the 'wasted heat' from the exposed plumbing is not very efficiently getting to heated building spaces.

Behind the walls

Were you able to do behind the wall plumbing with the drywall in place with access from behind or did you have to do all the in wall work first and pray for good drywallers? Either way it looks super clean!

insulation

depending on the insulator....

the job USUALLY doesn't look nearly as nice. It is true the 60 or so btu per foot on 1 1/2" could be considered wasted in some cases, however this is a slab heated garage kept at 72 like the rest of the house, and above the garage is a finished office/bonus room, so any residual loss i.e. standby, exposed pumps, etc. really does pull duty indirectly. Something I've toyed with is putting in electric stack dampers to cut down on stack loss, but with competition I can only go so far.

wall piping

The electricians eyes have crossed the last couple boilers I've done, so he runs power to the first box then I take the rest. It's easier than explaining all the connections to him. I always get it first. I put my piping in the wall, stub everything out, wire to my boxes then let them insulate, vapor barrier and rock. The other thing I've had the contractors do is paint the area white. Gloss or semi-gloss paint cleans up a lot easier than flat or bare sheetrock. I won't polish the pipes though! Homeowners can if they want to.

Very NICE

I just hope the drywall trade didn't use any of you hidden piping to attach the sheet rock. Only ever didone system like that. Wouldn't you know it -- "Captain Screw Gun" used 2" screws an nailed(screwed) my 1 1/2" horizontal main 9 times!!! The leaks showed up about 11 months later! ARGHH !!!
