Finally got the furnace people to come back and replace the broken gas valve in the studio. I had gotten a furnace installed in the studio last month (and had to dig a 2′ trench from the house to the studio for the gas flex pipe). The trouble was, during the installation, one of the workers accidentally stripped the thread on the final valve to the furnace, and had to get a replacement shipped in. Meanwhile, the weather got colder, and the furnace lay dormant in the studio, unable to provide heat.
Well, now the valve is in, the furnace is installed, and I can keep the studio heated all winter long without all those crazy electric bills. And it heats much much faster than the tiny space heaters.
