My son has a small 700 square foot home in Spokane, WA where we have better than average winters. We took out his old coal converted to gas heat source and are looking to replace it with ??? We purchased a lightly used forced air gas furnace on graigslist only to find it is quite a DIY project and it would be pretty expensive to have a installer hook it up. Where n/gas used to be quite a deal here in the Northwest, anymore it seems electric is just as expensive to heat with. To my question...my father-in-law jsut gave me seven 3 foot radiant glass baseboard heating units. They msut be 30 years old but have never been installed and are still in the boxes. They are rated @ 240 volts and 650 watts a unit. They have the radiant tube that glows red when turned on with a glass front covering. Are these things efficient or should we jsut spend the money to purchse some of the newer ceramic units and save these to put in my shop someday...
