Then that will cause the individual pipes to get 1/2 flow. That will work better if they feed with 1" using a 1x3/4x3/4 tee.

Re: How to pipe a Condensing boiler with heat exchanger for non O2 barrier pipe

Mine has been running since 2015 without any heat exchanger and no issues, so dunno.

There's not much regular steel, if any, in a combi boiler.

Re: Radiant Heat. Should I raise the temp?

If this is your closely spaced tees, it ain't. I think there are hydrolic problems with that set up. It's a bridge. Look at hot_rod's post out of Idronic at the closely spaced tees labeled 'C'.

I have never seen the connection pictured any other way.

That is absolutely NOT primary/secondary piping, that is a bypass and the boiler circ is pumping directly at the mixing valve. Also can you please explain the "safety issue" of 1 quart of 180 degree water hitting the radiant floor?

Re: Radiant Heat. Should I raise the temp?

A thermostatic mixing valve to regulate SWT is not the best choice. It has a high resistance to flow (a low Cv). I would prefer a valve with a higher Cv. A Taco I-series with a sensor mixing valve would have been my choice. A circulator (pump) doesn't suck, it circulates.

Doesn't appear to me to be piped primary/secondary. I assume you have the necessary check valves. (volute?)

Re: Can't stop the cycling!

May I as a silly question? What's turning off the boiler for that 1 minute chut down? That almost sounds like a pretty well sized boiler cycling on pressure, which is just fine. Not a problem at all.

On the possible leak — the quickest and simplest test is does the water level recover when the boiler is off and allowed to cool down some? That is, you set it at some level — note what — and then come back later after it as cooled down again, where is the water? About the same? If it, no leak. Slow returns maybe, and quite possible — they can be flushed if needed — but no leak. You only have a leak if you have to add water to maintain level — more than a gallon or two a week.
