Comparing cost of oil and electricity for heat

[root1]

..... I have an oil-fired boiler at my vacation home. I employ several methods to monitor the heating system & temperature of the house.
I recommend (for those with a modern Honeywell R7284 controller on their burner) a little-known Honeywell Alarm Module (#W8735S3000). It closes a contact if it detects any system faults on the data bus. It's pretty cheap (around $45) and gives you a few hours advance notice before the house temperature drops. I have mine integrated into the house alarm system which notifies me of any number of adverse situations. Solid and reliable.
The Carlin controller (#70200) has the contacts already built in; making life a little bit simpler.

I had an Industrial type Electric Heater with a blower in the cellar. Set at a few degrees lower in case Furnace failed. Furnace never failed in 20 years.

If house is calling for heat and doesn’t get it, it doesn’t take long to know something is wrong.
Some smart Thermostats have that built in.
