The furnace

My new little house has a total of 3 heaters. Ok, so far so good. It's the coldest time of the year and I have only 2 of them lit and I turn them down during the day when I'm gone. (Don't worry, the cats have fur coats to keep them warm) The problem is that one of them, if I turn it down too far, goes off. Then I have to light it in the evenings. Besides the fact that I'm all handy around the house knowing how to light pilot lights, it's annoying. Because even though I follow all the instructions and get it lit correctly, as soon as I turn up the thermostat, it goes on, then goes off. Then I have to light it again. Usually the 3rd time is the charm. Although I am all handy, that handiness doesn't extend to knowing what is wrong with the furnace or how to fix it. If I leave it up high, then it doesn't go off but that defeats the turning down the furnace when I'm gone to save money principle. Ah well, we'll see what happens. Spring is coming in 3 or 4 months, isn't it?
