Author Messages Oldest First Newest First eheintz81 Registered Users Posts:1 06/02/2008 6:50 PM   I am a new homeowner that inherited a 25+ year forced air heating system.  I would love radiant heating for the comfort factor but I am wondering if it is a bit overkill here in Atlanta.  We generally use the heat from mid-October to early April and the temperature rarely goes below 25-30 degrees in the winter (high in mid 40s).  It would be installed in a crawl space under the main floor.  It is a 1600 sq ft ranch.  Any ideas on companies who install down here?  Every one I have asked stared back at me blankly.  Help?

As far as help installing it, you might want to try to do it yourself. even if you cant install it yourself, you can buy the tubing. then you can find a handyman to do the work. I f there is insulation there already, that will have to come down first. Then the new tubing goes up, and re-insulate. it wont work w/o insulation below the tubes.

The advantage is a difference in almost $200.00 a month in heating cost during those chilly to cold months. Install it, it is the best. engineer Registered Users Posts:263 06/09/2008 8:55 PM   I'm curious to learn how electric resistance heating in any form with its COP of 1.00 can be $200 cheaper per month. In mild Atlanta any halfway decent air source heat pump should run at a COP of 2.50 or better. I understand how a radiant floor allows for a slightly lower thermostat setting and thus a bit lower heat load, but not enough to overcome a 2.5x difference in cost per delivered BTU. $200 per month cheaper than what alternative? Burning dollar bills directly? Without data, you have only an opinion...without measurement, there can be no control Brock Registered Users Posts:137 06/10/2008 11:11 PM   Do you mean $200 a month less in winter? Well then my utility bill for my 4000 sq ft home with an indoor pool would under $100 in the middle of winter ;) I will have to look in to that.
