How Much Extra Electricity Vs. Oil?

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Has anyone kept track of how much more electricity is used by a DF-520 over a conventional oil burner?

Heating with coal, driving with waste vegetable oil. Screw OPEC.

Since some oil burners use constant ignition transformers i'd have to guess they would use more.

My electric bill is up about 15.00 a month since October when I first started running my 520 but I can't say that is all because of the 520. I did notice my coal unit runs longer than my oil unit did but my house is kept at a higher temp now. Even if all of the 15.00 a month increase is attributed to the coal unit I'm happy and saving a ton of money on oil.

My forced air blower sucks the zap juice pretty good so I can't comment on just the stoker, in the summer it's not a noticeable difference and I use the 520 for my hot water. It's only got a 1/8hp motor so it can't cost that much.
Burning coal is definitely worth the extra work involved.

I have a customer who has been running the unit for a couple of weeks now, and he is not too happy with the EFM 520. His reasons are that he is burning 4 bags a day, and he said his electric bill has gone up 50%. It is a FHW system, with one circulator, and 4 zone valves. The house is about 20 years old and 4,000 sq. ft. I think his coal consumption is high, the electricity usage I would have to see it to believe it. I would like to get his numbers to where they make sense.

I think he needs to give more information about his 520. Such as: What are his settings. What draft measurements does he have. Was oil costing him $5 a day and he expected coal to cost 5¢ a day. Questions like that.

Very happy to post here.

My electric bill has gone DOWN $30 to $40 per month.

I have an electric water heater and that DHW coil is a life saver.

I also was used to running a corn burner which uses more electric than the 520 motor + water pumps so all and all I am very happy.

My bills used to run right around $100 per month in the winter. $70 in the summer.

now I am going about $65 _$70 per month in the winter. i'll take it...

Lest we not forget, in the winter it is dark more than it is light and we spend more time indoors so we use more energy regardless of the heater. To make matters worse I'm on the adjustable rate plan so it's hard to compare without doing some math. I'll bet my Christmas lights used more juice than the EFM. ;)

Our electric bill for December was $100 less than November :dancing:
Of course we lost power for 5 days during the ice storm and the wife is now using the coal fired clothes dryer instead of the electric one :secret: (Huge difference) I am also running up to 7 fans in the house but my stove is hand fired.

If we have power for a full month I estimate we will save about $50 not using the dryer even using the fans, this was not a savings I calculated when deciding to go coal but should reduce the payback period even more :punk:

I've got a Keystoker K-2 Boiler. Between the combustion fan and the stoker (even if running continuously), they would only draw about 1 amp @120v. Somewhere around 120w, 2.9kwh/day, 86kwh/mo. In Syracuse @$0.14/kwh, we're talking $12/mo, fans and humidifiers a bit more. Small change here.

the wife is now using the coal fired clothes dryer
What is that???

Our electric bill dropped $30 a month when our last child got his own house and it has remained fairly steady at $65-70 a month. I'm running two circulators pretty much all the time.

A wonderful marvel of Yankee ingenuity and basic engineering.
I wrapped a clothesline around some of the lolly columns in the cellar.

She also uses a wooden rack for some of the smaller unmentionables :up:
