I'm trying to compile a list of services for our customers to choose or decline. Is anyone out there cleaning hot water boilers with tsp or hydrochloric acid or anything else? I'd apprciate your tips and procedures.

While we're at it, if you have a procedure on steam boiler service work or a new install, please fill me in.

    Wow Gary that's a tough order to fill! You know I always use TSP for my boil outs on new start-ups. One thing you need to do first is get rid of the box that says TSP as soon as you dump it into the boiler. Most citys won't let you dump phosphate down the drain. If I were you I would consult the factory on the exact proceedure. I do factory service for Bryan, Weil-Mclain, B&W, and hurst. They all wan't something different done with their boiler.

    When I do a general service I pull off all controls, LWCO's, and steam auxilliarys. I clean them all out at the sink with an abraisive that won't impede their functionability. Also inspect the water and steam connections and make sure that there is no blockage that could cause a false water level. If it is a two pipe system make sure that the condensate pump outlet pressure can overcome the pressure in the boiler. Also check a sample of the condensate line. Check the operation of all safey devices as well as the flame safeguard.

    I clean

    all my installs.

    This should be standard procedure, not an option! It is very critical with low mass, low water content, multi metal boilers these days.

    Also look into hydronic, or steam system cleaners and leave the other "brews" on the hardware store shelves.


    Pretty much all the TSP products available to the public are phosphate free these days. Which should tell you something about the cleaning ability inside that hydronic system :)
