Delta-T on TT-110

Jimbo_5 Member Posts: 218
I have a Tringle Tube Solo 110 running without P/S piping heating 9 ci radiators. Currently my Delta-T fluctuates between 20 & 30° depending upon firing mode. Does this seem like too much? I'm on the lowest pump speed to get this spread.

    It would be easier to understand, if you sign up for Tacos FloPro University, and watch the tutorials in Hydronics Step By Step. It's free, and you'll enjoy it.

    I like the delta t you are getting. It is difficult to do with that boiler.

    Agree with Carl here -- that's about as good as you're going to get. We have one that sees about the same numbers (on cold days, anyway) on a series convector (big commercial stuff, with double 1-1/4" pipes) loop.

    Most people with tt110's would love those numbers. I get about a 14 but am piped p/s.
