So what does it cost to heat a leaky old uninsulated double brick Victorian? Well here is the answer, for the years 2003 to 2010 inclusive. I started these excel files back in 2005 or so, continually improving them every two years or so.
Interestingly, the cost of natural gas for '01 and '02 was $2280 and $2330 respectively. In 2004 I purchased a Hunter brand setback thermostat to replace the original vintage dial thermostat. We did not often turn the heat back at night, but after purchasing the digital one, it was programmed to do so automatically, with what appears to be a significant corresponding savings in fuel consumption.
