1 Ton Heat Pump

in THE MAIN WALL
Anybody know of a manufacture that makes a 1 Ton Heat Pump? I am bidding a apartment building that has about 100 apartments with a central chiller & boiler system. When I ran the load calculations I calculated 6300 btu's heat gain and 9100btu's heat loss. The goal is to install separate heat pumps and keep the existing boiler and replace the air handlers with a hot water coil for back-up heat. The electrical service to each apartment is limited.

Thanks,

Ron

    Hi Ron,

    We installed a Trane 1-ton heat pump a couple of years ago. I don't know if it made the 13 SEER cut, though. York used to make one as well. Good luck! -DF

    Sad to say but...

    looks like 1.5 ton is all still made. I did a search on ARI, nobody makes a split HP under 18,000 BTU. Hate to see them being 3 times the needed size using a 1.5 ton though.

    I suppose no way of putting in a water source heat pump which are made down to 3/4 ton.

    I would vote

    for water source too but that is a different animal. 1.0 ton DX cooling only is one thing. Heat pumps- have never seen them in a 1.0 ton range let alone 0.75 ton range. I think there is a market though!

    The magic of a shared dumping ground

    Bam, what John Mills said

    Water to air heat pumps units in each apartment that produce either hot or cold air and feed off one water loop that goes to an outdoor coil and the boiler.

    Dump the heat outside in the summer and recuperate outdoor heat in mild weather with the outdoor coil. In deep winter, bump up the heat in the water loop with very low temperature boilers.

    What's ideal during the mixed up season, you can cool some apartments and heat others by trading the heat through the dumping central water loop.

    You could even (if calculations make sense) keep the chiller for dog days summer and precooling of the central loop and not worry about going even smaller on the individual heat pumps.

    There is a company that makes neat units such as these that fit in ceiling tile openings, and the name escapes me right now. Mutlicoil, I want to say.

    1 ton HP

    Ductless is all I know of in the 1 ton HP. Check EMI, I think that they are www.enviromaster.com, they used to have the ability to add hot water coil in the air handler (not all), electric strip heat and heat pumps to 9000 btu.

    The through the wall PTHP from GE (Zoneline), McQuay, etc. come in the smaller sizes as do the ductless splits such as Sanyo and Mitsuibishi. Carrier also markets these.The smallest standard ducted package and splits go to 1 1/2 Ton that I am aware.
