Hi the system we have is really beat in a lot of different ways and thinking it may be better to just swap it with a new system. Is there a close to direct fit or other brand that could be used. This only heats 1 large room with high ceiling, about 700 sqft. Would like th ability to add AC later but not required at first

    Er... um... it would be a lot easier to answer your question if we had some idea as to what you have now and are trying to replace.

    That is a hydro-air hot water fan coil designed to provide space heating from a domestic water heater. It has its own circulating pump. They are generally installed where the heating load is small, to save the cost of a separate furnace or boiler.

    Those are rated for use with potable water. Most space heating components cannot be connected directly to a potable water system due to the risk of bacterial growth or other contamination. Many in the trade dislike this type of system due to that risk.

    What type of water heater is it connected to?

    Is the air handler bad? Or the HW tank?
    They used a 65 or 75,000 BTU/ hr water heater that had two side taps, nothing special 

    measure the size of the coil it complete AH to get a close match

    First Co, Magic Air, Lennox, Carrier, many others make such a unit

    These were very common in apartments for heat and DHW

    The key thing about the tank is it had a sticker that it was approved for hydronic use. So we bought the tank for radiant jobs, the inspectors were fine with the approval in the tank. These were stand alone radiant, not combined or open systems

    Williams Company still manufacturers combined system components, although I see HX in their systems now
