I live near Philadelphia. Can I use warm wire as the sole heat source in a new addition(kitchen and mud room). Insulation is above average with 3 exterior six inch walls with R-19 insulation on all exterior walls, ceiling and floor. Total room sizes are 460 sf and 190 sf.
Do you have a BTU Needs calculator that I can use to be sure?

nastom- WarmWire, in some cases, can be used as a primary heat source. An indicator you must look at besides the wall R-Value, is the construction of the floor the WarmWire will be installed over. For instance, WarmWire installed over a frame floor will typically perform better than over a slab. It sounds like you are installing over a frame floor with a crawl space. In your described application, WarmWire has a very good chance of being used as a primary heat source. To verify this, you can send detailed plans of the area to designs@watts.com, and we can return a heat loss for you at no charge. Or, if you are familiar with heat losses, you can download our free RadiantWorks software at www.wattsradiant.com/support/radiantworks-MDR
