i Have a 500,000 BTU oil boiler and buying another 300,000 BTU . How to connect both of them to give higher rating as well to act as standby for each others ? Will the same piping work ?

    How does the heat get from the boiler to the rooms? By hot water, or steam?

    It's industrial boiler . Oil goes in pipes to heat water and other chemicals .

    First inclination is not to mix circuits. Separate heat exchangers. If you scorch thermal fluid the entire circuit including boiler and heat exchanger has to be purged and cleaned.

    I'm thinking primary/secondary, but really need to know more about the existing piping setup. Got a diagram? Photos?
