Boiler Header?

Cyclist77 · July 27

As I continue to plan my installation I would appreciate a bit of advice. I will need a header as I will have indirect hot water tank & a 180 degree loop. The main heating is radiant floor heat.

Would a " homemade "header be preferably to a pre-made? I thought I had read on some far distant post of quality concerns with pre-mades.

Depends on your craftsmanship and ability to source components. If you can find the correct components and your design and craftsmanship are up to what Caleffi or some others can do, yours and pre-made will be equal. Yours will probably be more expensive, quality for quality.

Manufacturered "Speed" headers save tons of time. That's their biggest advantage. Mad Dog

Sounds like you just need 2 tees for a three connection piping? Are you considering copper or steel pipe?

Cyclist77 · July 27

My idea was as a steel pipe header as I would mount the circulators on them. I could go copper for more $.

I did slide the boiler into a rough position to start being able to visualize the piping and the gas line. I am try to determine where I want to set the indirect hot water tank so it Isa bit of a chess match!

I'd avoid a steel pip header. Copper is amply strong to support the pumps — and steel rusts. Unless you have steel elsewhere in the system and the necessary filters and magnetic concentrators, you'd nee to add them for just the header — and that's silly.

Guess what circulators are made of…. A little bit of iron in a closed loop system is of zero consequence and absolutely does not require filtration or magnetic "concentrators".

Where did I get the idea that at least some circulators are bronze?

Some are but they cost a fortune (stainless is out there too for a larger fortune). They are advised for things like open system stuff (hot water loop off a steam boiler). But I have been running mine with a regular cast iron one (for five years so far) because I figured I could buy three of those before it made sense to buy the bronze one.

Also I couldn't figure out why having a bronze circulator connected to a bunch of steel pipe and a cast iron boiler would prevent or slow rust issues.

You can mix and match iron and copper and even brass in a header. It makes sense to use iron nipples if you are just threading 2 threaded devices together and you have some fudge factor in location. It makes sense to use copper where you need to cut to exact dimensions.

Is Earthlee Header Co still around? She welded some custom steel headers for me years ago

Maybe a name change ?

I have seem them at wholesalers as Speedy Headers
