http://forum.warmlyyours.com/forums/1/topics/28 en-us 60 <p>Scott,</p> <p>I am going to look into this as much as I can for you. For right now I can tell you that we do not offer a product that is listed for exterior applications in 24 volt. Generally, the size of the area being heated requires that 240 volt be used. I will post again as soon as I find out more details</p> <p>Seth</p> Thu, 03 Apr 2008 22:05:55 -0000 forum.warmlyyours.com:1:28:75 slavigne http://forum.warmlyyours.com/forums/1/topics/28 <p>Seth,</p> <p>Did some additional research&#8230;below from one of your competitor&#8217;s websites:</p> <p>&#8220;It is normally connected to a 24V transformer, but it can also be run by a solar or wind-powered source. Because the elements are self-regulating and cover over 60% of the floor surface, (other product) is more efficient (up to 30%) than cable and hydronic systems and up to 60% more efficient than conventional forced air systems. The system is easily zoned too!&#8221;</p> <p>Would be interested in a compatible package (or at least recommendations) of solar panels and wind powered generators along with an electric radiant heat system (especially useful for off grid applications)...keeping it all DC would greatly (~30%) improve efficiency so more heat goes to the floor rather than wasted in the transformer(s).</p> Tue, 01 Apr 2008 21:14:09 -0000 forum.warmlyyours.com:1:28:74 scott http://forum.warmlyyours.com/forums/1/topics/28 <p>Scott,</p> <p>I am by no means an expert in dealing with solar power, but heres what I was able to come up with through some research:</p> <p>The easiest way to use our system in conjunction with a solar system is going to be the introduction of an inverter. This will convert your DC power into AC which can then be stepped up or down through the use of a transformer.</p> <p>Using DC to power our system without an inverter would be difficult as you would need to produce 240v at the appropriate amperage (which would be determined by the length of the resistance wire being used). Wiring batteries in series will increase the voltage, while wiring them in parallel will increase their amp output. For example, to provide 240 volts you would need 20 12v batteries wired in series.</p> <p>I hope this information helps, and if anyone on these boards has more insight into the matter, please feel free to chip in!</p> <p>Seth</p> Tue, 01 Apr 2008 20:05:25 -0000 forum.warmlyyours.com:1:28:73 slavigne http://forum.warmlyyours.com/forums/1/topics/28 <p>for efficient use with solar and/or wind power, are there DC versions available (especially for outside, driveway snowmelting applications)?</p> Sun, 30 Mar 2008 21:26:35 -0000 forum.warmlyyours.com:1:28:70 scott http://forum.warmlyyours.com/forums/1/topics/28
