    Swapped out an old boiler for a 4 Plex. I wasn't there for the demo so i have no before pictures. The system runs on 120VAC thermostats, my first time working with them.

    what are the radiants? looks great except it's missing two items that will make purging easy/peasey. at the top of the supply before the x-tank should be a tee instead of an ell with a boiler drain on top and then a ball valve right after.
    close the valve and while filling the water has no choice but to chase around the loop back through the boiler out the drain on the tee. all purging done right there......

    otherwise great craftsmanship.

    Venting looks suspect. Air scoop is not installed correctly and is rotary phone technology. What's up with the 4 porcelains with the fuses? I agree a drain valve in the right place would make purging easier (unless you have column radiators), and a Webstone expansion tank valve, so you can easily isolate and check exp. tank charge.

    Soldering looks awesome. I wish I could solder like that.
    If I do a job in 30 minutes it's because I spent 30 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.

    Now I know what the boiler is. Lochinvar. We put one in a teeny little rental house. 75K when should have been 50 but smallest boiler we could find plus it has a 2 stage gas valve based on water temp we were told. Even has outdoor reset standard.
