help on a heating problem

depending on how much additional heat you are looking for, you could try something like what i am about to propose. it is very unothordox, but it should work.
what you could do is use an electric water heater with pex tubing. electric water heaters are typically 220volts, so you would need to find a central place to put the water heater, then have an electrician wire it for you. an easy way to run the pex tubing would be to buy the pre-fabricated trac and run it along the walls. the best place would be under and around windows, because the incoming drafts would be heated up, thus acting like a forced warm air system. the electric water heater should be set to about 130 degrees. this should be a cheap and effective way to solve your problem.

problem with heating office spaces

I got a problem job that I am hoping someone out there can offer some advise on. The way the job is set up is a three-story office building with the second floor extending out past the first and third, making it in essence cantilevered out about 20 feet. The building is now occupied and I am having problems maintaining temperature in the offices over the over-hang. The construction of the floor is 4” concrete slab and 2” foam insulation and a metal pan ceiling (the architect really helped us there). I cannot dump any more volume into the room from our heating system, we already have it blowing wildly into the space. The only resulting discomfort in all the offices in this area is that it is really cold under the desks and at the floor. What I was thinking about doing was to try installing a hot water heating system-using PEX piping under the overhang. Since it would be hard to force the heat up through the slab into the space I was thinking of creating an interstitial space (about 6”), installing the PEX, and insulating again sizing the PEX piping to the heat loss through the lowest portion of insulation plus the heat loss through the floor. Working all the numbers, I think this will fix the problem by forcing a slower heat loss from the spaces above. Anyone ever heard of doing anything like this before? My customer on this job is a very good customer and I have to take care of him. I also want to do it right the first time. Thanks for any help!

oh yeah

almost forgot to mention : the water will need a circulator, a swiching relay, and a thermostat. these will be what control the heat, for when you need it and when you dont.

Baseboard heaters under desk

I would put in electric baseboards under the desk. I am assuming there are partitions. Just mount the electric baseboard along these. When they remodel these can all be moved easily enough.Most office buildings seem to always have ample service. Good luck
