winter boiler work

[greenmonster304]

I have been working on this the past two days for the HVAC guy that I help in the winter. Its a high efficiency condensing gas boiler made by Triangle Tube. Its pretty cool one guy can lift it and hang it on the wall. This is for his own house. This is just for hot water and back up heat he also installed geo thermal heat pumps which work really well. I still have some more piping to do and I will take more pics when its done. This is the first one I am doing solo, I have helped on a few other installs. I really like putting all the pieces together but maybe its just because its new to me.

Don't forget a pressure gauge in there somewhere after the PRV. Why the steel pipe and not all copper?

What do the pumps serve? Radiant floor, finned tube, domestic water heater?

Well first, Good Job! Keep it up!

I ask the same with the mixed pipe?

Also I see you have top manifold is out of the wall a couple inches. It may be worth to have a small cabinet there for easy access as well as protecting the protruding pipes

I am not sure about the mixed pipe that was the material that was provided by the owner. He may have wanted to save a few bucks. I would have liked to have used all copper but not my decision. the premade welded manifolds were nice because they were all plumb.

The circulator pumps on the top feed hot water coils for hot air heat. The pump on the bottom feeds an indirect water heater.

Steel is fine for heating work because the water inside will recirculate and lose the dissolved gases that could promote corrosion.

all done, will check for leaks next week

That would make a good slogan ~ "If you got a leak, we'll see you next week" :)

the job looks good from the pictures, the only comment i would make would be that i would paint the plywood prior to installing. the paint not only protects the wood, it sets the plumbing job apart from the competitions.

if you test with air, any leaks can be repaired quicker than if the system has water in it.

i wanted to paint the wood but there was no time. the guy i am working for just said you need to start the boiler today. he wasn't even going to have me put the wood up. he wanted me to hang all the pipe from the ceiling but i told him we need to put up some ply wood.

The pre-made steel headers are much stronger and need less support (per lineal foot) compared to copper. Those circulators have some weight to them.

Copper pre-made headers most likely do cost a bunch more. And sweating an 1 1/4" or 2" cu header is a pain - BTDT. The headers you used save on labor time and potential leaks of assembled individual pieces.

Webstone flanges for the circulators are also a big labor saver for assembly and future servicing.
