    In-Duct Hydronic Backup Heater for heatpump

    I have a goodman/frigidaire 2.5 ton heat pump, without any electric heat.

    Well my in-floor radiant heat took a dive, and i'm not digging up the concrete floors to fix it.

    Can an in-duct hydronic heat coil be installed instead?

    Only coil i have found on the net is: http://www.houseneeds.com/shop/Heati...oilersmain.asp

    Is that a decent unit, or is there something better out there.

    OH and was thinking the 16x18 would would work with the 1200 or so cfm well. Should i go bigger. I could fit the 20x20, but i don't have the gpm to keep up with it... i don't think. (not 100% on the the gpm of my pump) I've heard this air handler is known for a weak supply air fan.

    btw: i'll be ok on the controls.

    I've never heard of this being done... but i don't see why it couldn't be done.

    Thanks.

    Add on Hydro coils are fairly common.

    How many times must one fix something before it is fixed?

    cool!

    So the local a/c supply house won't laugh at me when i ask for one (or 2)?

    Any one have technical sizing tips?

    Tell you what. Since you're obviously going to do this job yourself. Get the biggest hydro-coil you can find and stuff it right in the trunk. Set the blower for the highest speed and stand back and enjoy the show.
    If YOU want change, YOU have to first change.

    If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

    There are a couple ways that it can be sized(right).
    It depends on how you want it set up.

    Your local supply houses may or may not be familiar with them.
    Here they are.
