thats an important piece I forgot to mention, I have electric heat pump....On average my electric bill would go up about $200-250 a mth from November to end of Feb.....so essentially I have at least cut my heating cost by at $300, as much as $500....To show how bad heat pumps stink to heat with....Same system only using AC in summer my bill goes up about $60-100/mth...k-2 wrote: ↑Tue. Feb. 12, 2019 10:08 amMild winter i see a 3 ton avg use. Or about 75-90 million BTUs. In colder than avg that can go to 4 ton or 100-120 million BTUs depending on coal quality. Im saving almost $900 in oil on a mild year and $1200 on a cold year ,that with $2.25+ Gal oil prices. When oil is higher its much more. I still have the oil installed as backup but rarely ever use it. Keep house an avg of 76 degrees although when it gets very cold i go to 78 just for fun. 3000SF of leaky 100 yrold house.

Dont forget in summer your only changing the inside temp a few degrees
perhaps 20-25 Deg at the most. In winter ,at times temp diff between inside and out may be as much as 70 degrees.

We have a 4000 square foot house that was built 30 years ago that sits on a hillside and has brutal winds in the winter. Heating with a Keystoker KA-6 boiler. Use it year round for hot water in the summer and everything in the winter. Keep all daily coal usage in spreadsheets going back to the install date. Average coal usage is 7 tons per year. Range is 5.8 tons to 7.8 tons depending on how cold it is.
Before the coal boiler was installed we used an oil boiler. That averaged just about 1200 gallons of oil per year for heat and hot water. I believe the coal looses some efficiency in the summer for hot water versus the oil. I run it year round to also prevent any possible issues with moisture / rust in the summer months from downtime.
