Thanks, this helps greatly. I'm not really concerned about the energy use, so long as it isn't crazy high and with the price of nat. gas falling I feel its's a sound investment for up front costs. I do have a separate room for it to be installed in so that's not an issue. I am working with the city to check local and state codes regarding it's use and location. I've been able to find several gas powered steam systems that are about 1/3 the cost to purchase and install vs an electric system.
Thanks
Brian
