Will one of the wall unit condensing boilers work with cast iron radiators?

    Radiators and new boiler

    It's a perfect combination of high mass radiators, and a modern condensing boiler. However, the cheaper look-a likes from the big box store may only be water-heaters, which will not work as boilers.--NBC

    Who makes the better condensing boilers?

    one more thing for now

    Some of the boilers I am looking at rated by input. How will I now what the output is. Right now I have a gas conversion burner that set up with 100,000 input would the condensing burner be about the same.

    Heat loss

    The only way to correctly size a boiler is to do a heat loss calc.

    The output is the input derated by efficiency.

    A 100,000 BTU boiler that is 90% efficient would have an output  of 90,000 BTU at sea level.

    Lochinvar,Triangle tube and Viesmann  are some good choices.
