Piping a steam boiler for HW circuit
HEATON
Member Posts: 118
Advise to a church client is my proposal to remove a leaking 50 year old 240m btu input that has a connected load of 50m btu heating units for the basement, the main boiler about 10 yrs old is a weil mclain steam unit. I need drawings to take this HW circuit of that steam boiler and discard the dangerous inefficient dinasaur . Ive done this once on another job but too long ago to remember. appreciate comments and support.. Heaton, John H Washington PA

Are you speaking of thousands of BTU's? M indicates millions.0

Funny (or not) aside...RobG said:Are you speaking of thousands of BTU's? M indicates millions.
My wife is a commercial banker and always sends me short hand of "Our portfolio just went up $3M"
My response is "Get the jet ready, we're headed to the Bahamas!"
She shakes her head at her uncouth husband and explains in financial jargon shorthand, M is thousand, MM is million.
or mille=1000 and mille mille is 1,000,000

M is roman for thousand and often used for this.
Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

A frequent source of confusion with engineering drawings, BTW. In school we were taught to use K, which to me is unambiguous. M (and m) leave me scratching my head sometimes.0

True,SWEI said:A frequent source of confusion with engineering drawings, BTW. In school we were taught to use K, which to me is unambiguous. M (and m) leave me scratching my head sometimes.
But did anyone think a church actually had a 240,000,000btu boiler and several 50,000,000 btu heating units?
That's a big boiler.Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

Does that make it a mega-church?

back to the issue, are you still using steam in the other sections of the church? 240mbtu is not a dinosaur it is a large dog.Cost is what you spend , value is what you get.

I stand corrected for not using proper hydronic slang. The boiler I am proposing to replace or eliminate is is a" large senior dog" . Is it still OK to use the word senior? Or is that now discriminating against a disadvantaged class? The 240,000btuh input boiler is providing hot water to two space heating zones. One with around 50,000 btuh at 180 deg f and another with 2 small cast iron radiators totaling 10,000btuh. each has its own circ. and stat, The steam boiler is a Weil Mclain 1.2MM input supplying steam to radiators to the rest of the church. Thats 1,200,000 btuh. Now I forgot what the issue was, Oh yes The piping and controlling of a circuit for this hot water portion of the building, of the steam boiler. Some of my old notes show a heat exchanger being utilized and a pump on the steam boiler side. This gets to be not cost effective when comparing $$ to a replacement (sized properly) boiler. Any (usefull) info ? Thanks for your eagerness to help, always. JH0
