SS plate heat exchanger Vs. a dual coil side-arm heat exchanger?

Options
Which is the best type heat exchanger to use in a hotel hot water system with 2- high efficiency, sealed combustion boilers? Stainless-steel (plate-type) heatexchanger or a dual coil, side arm heat exchanger? Will the plate-type gunk-up and be hard to clean? Which will last the longest? What other maintanance issues are there? What about cost? Any help appreciated.

Thanx

  • side arm vs plate type heat exchanger

    presume a hot and very high input/output boiler. In these times of accellerating energy costs an indirect tank with a non oversized boiler makes the most sense.

    Both alternatives that you proposed are service intensive. In my experience the plate type will plug up more thoroughly if the system water is very contaminated.
