NTI combi powering 8,000 sf of radiant and DHW.

Wow! That is beauty & perfection.

Excellent, clean and simple!
Super job!!

Very nice! who do you buy those expansion tank bracket things from?

Harvey Ramer

I get the tank brackets from supplyhouse.com.

I love love love the ability to pipe a radiant system direct to the boiler! It's great when that works out!

If the two big red radiant zones are not calling will the 2 or 1 small black zone be able to meet the min flow for the boiler? Or is that not an issue with the NTI?

This boiler actually has built-in primary secondary piping within the boiler cabinet. Not that it's needed on this job.

The 2 small zones are for the 2 bathrooms. They are controlled with straight-body TRV's. The one on the right has a direct mount operator. The one on the left has a remote mount control for the operator. They only get flow when one of the big zones call for heat. But, since the system is running an ODR curve, they get plenty of flow.

Very nice, sir!

What brand of manifolds are those?

P/M me and tell me your cost and sorce, please.

Hey Harvey looks good, which model NTI is that? Looks like Tx151c but that doesn't have built in primary secondary piping?

Tom_133

Ok with a little research I think it may be a Vmax153. So how much hot water do you think you are really getting? The problem many had when Triangle tube had a similar model (prestige excellence) was guys were mistakenly installing them where the customer had a soaker tub, and it ran out too soon. I saw the numbers on this Vmax and it seems impressive, just wanted real world numbers

Harvey Ramer

@Tom
It is the VM153P. I can't really tell you about the real world hot water production. I only have 2 utility sink/tubs connected at this point. Reason I choose this one is for the small indirect built into the boiler. It keeps the boilers from firing every time someone washes their hands.

I would like to add something. This boiler requires a mixing valve on the DWH. I didn't put one in because they want the hotter water for washing misc crap in the utility sinks.
With the DWH set at 120, it produces 140 degree water for a while. Has to do with sensor placement I believe.

I noticed the lack of mixing valve but knowing your work, I assumed the best and you confirmed it. How do you find jobs that allow such a clean room? Im stuck in every 1850s basement dungeon imaginable.

This one was new construction. And since i was involved from the inception of the project, I was able to plan everything before the project even started. That was nice.

I work in plenty of old basements as well

Paul Pollets

Nice. 16 loops for 8000sf?

Harvey Ramer

Yes. Some are spaced at 18" some at 15" and some at 1'. And the red tubing is 5/8", allowing for longer runs.

Tom_133

Good catch Paul.

Thanks Harvey just ordered those brackets off Supplyhouse.

cwilliams2000

Wow, now that's my idea of a boiler room! Looks like an operating room.

Gorgeous job, well done. Love the red bracket for the expansion tank, as mentioned earlier.
Only comment/question...why the reddish brown color in the acid neutralizer chips already, if system is brand new?

DZoro

I installed a Noble NKC 199 this past week and also noticed condensate rust colored. Think maybe heat exchanger oils? I cleaned the drain and seemed to run clear 2 days later....

Harvey Ramer

I honestly can't tell you about the rust colored condesate. I noticed it as well.

What @Dennis said makes sense.

j a_2

That is truly a professional job....Guys like you raise the bar...

dfehr401

Who ever installed that might have OCD lol. That is awsome i wish my plumber was that good.

I talked to NTI about the condensate coloring the neutralyzer. They said it is perfectly normal with this boiler.

Nice professional job, and I am sure the client will show it off!
I would want the kill switch a little farther away from the boiler, however!—NBC

Neat & squared away, soldier. Carry on! Great clean work Harvey. Mad Dog

The load center is right outside the door to the room with the circuit breaker for the boiler clearly marked.

so happy to see people understand high efficiency and the benefits to them and the environment, great looking boiler room,nice clean piping design, top notch work, wish more people in my area wanted systems such as this

rick in Alaska

Nice job Harvey!
What brand is the air separator you are using, and why does it have what appears to be two caps on it?
Rick

Shane_2

Nice Job,

Like the Watts RBFF as well. Been using them on every boiler install since the Watts rep gave them away here on the Wall many years ago.
Was wondering about that air separator as well. Comes with the pump flange?
Shane

Gordy

That second port is a vacuum breaker for quick system drain down?

I like that flexcon x tank bracket.

Harvey Ramer

The air sep is a Watts flanged micrbubble air seperator. An excellent space saver. It gets the job done, but not quite as quickly as a caleffi or spirovent.
The one cap is for rapid air release, such as system filling. The other cap remains loose for normal venting.
