    Ah yes, variable speed salvation. I'm guessing though, that it happens all at once. But what do I know? I'm only a plumber.

    Blasphemy!

    Now say 10 Hail Mary's and a good Act of Contrition then go and sin no more ✝️

    After you make that expensive repair and you still have the same problem, What will you check next?

    I'm not religious. I just like the stories. Besides, I only know "Hail Mary, full of grace", then I'm lost. Can I do 20 of the Lord's prayer instead?

    At the First Baptist Church in the Back Bay section of Boston, built in the 1870s, the baptismal font had a cast iron one pipe steam radiator in it. The air vent was piped up above the flood rim. Simple and effective.

    For Cripe's Sake! @HVACNUT

    That would be Jesus Cripe, Son of Gosh, along with Great Cesars Ghost, of the Roman Church of Holy Moley. For those that are not of this faith

    I think normal swimming pools run at 81-82

    @EdTheHeaterMan thanks ed .

    The customer is fixed on a boiler set up. For your proposed set up which I like, is that with the boiler loop with a automatic bypass valve or primary secondary? Can you make a piping arrangement diagram? And I was thinking a tekmar 150 for controlling the pool temp. Thanks again

    With a CI boiler you need some sort of return temperature protection if the tub is heated to say 85- 100°?

    A 3 way protection valve is ideal, or cobble together 3 ball valves and manually adjust flow.

    So you can use whatever device between the boiler and tank.

    With an indirect it may have the temperature control built in. Set it to the desired temperature wire it to TT on the boiler.

    A setpoint control like a Ranco, Johnson control, etc would allow tighter more accurate temperature control, and digital readout. Probably less $$ than a tekmar 150 and more features.
