    Is there any manufacturer out there that uses high efficiency gas heating equipment for a "Unico" type of system. I went out to my wifes girlfriends house tonight to look at getting her a better source of heat. She currently uses only a wall furnace and the fuel costs are killing her. Due to the home having three additions to it and therefore four different roofs/attics, Duct in the attic is out. Putting duct in the crawl would be almost impossible since the crawls only two blocks high and filled with plumbing.

    The ideal thing for this place would be a high velocity system using small pipes,but Unico only offers their systems with electric heat. Someone must have come up with something out there for this type of need?

    The name escapes me...but there is a system out there with a hot water coil built in...

    I haven't done this myself, but . .

    if you have a unico system, couldn't you put in a gas furnace as long as the air flow was enough?

    That's what I was going to say.

    One of the last jobs I did in Detroit was setting up the controls on a built up system some maintenance guys at a steel fabricating shop put together.
    They piped a loop off the main boiler and fed a hot water coil in a box with a fan that created a lot of Static pressure and fed the air thru 2" flex duct to the offices. Worked quite well.

    You could use a Unico and put a hot water coil on the return side of the Airhandler.

    Only high efficiency water heaters (96%) Iv'e seen are the A.O.Smiths and they are around $2500.00 to $3000 just for the W.H..

    I'm hoping for a less costly means, since the house has a heat loss of only 37,000 BTU's.

    Rinnai......82%.....

    High efficiency is over-rated....can't achieve rated efficiency at 120 return anyway..
