Electric costs for boiler system

Mine rose by negative $150 per month early in the heating season, replacing baseboard electric with an LP boiler and pumps drawing 60 watts total.

At 12 cents a kwh, an average load of 230 watts will cost about $20 over the month.

My bill definitely went down, boiler controls and a couple of circulators are cheaper to run than a forced air furnace. I had a kill a watt hooked to my system last winter and only used around $30 for the whole season.

It depends on what you are replacing if replacing forced hot air your electric bill will be significantly lower. There are many factors, how many pumps pumping 24 7, ECM pumps zone valves etc.

I pay 12 cents a kilowatt My circulators are 85 watts, even if they ran continually which they don't (85w X 24hrs x 30days = 61200watts), that's (61.2kw X $.12 =$7.34).Not sure what the fan runs but is low wattage as well.

Here's a similar conversation we had last year. My response was #6 and #28
(Actual usage for the month of December last year on the 1 circulator was $3.44)

My bill went down $50 per month. I replaced a wood stove and electric water heater.

I was running an oil boiler before. Bill went down. Just circs instead of circs and blower on oil boiler.

Loading unit pump = 60w +/- x 8hrs/day (avg +/-) x 30 days x $0.18/kwh = $2.50/mo. +/-.

That's the only strictly boiler electricity being used - no fans here.

Load pump = 1/3 the wattage, so even if it ran 24/7 that would be another $2.50/mo. +/-, zone valves no idea, but those costs would be there no matter what made the heat.

I'm pretty sure the old wood/oil combo used more than that, between the juice the burner used when it was running, and the old B&G ? bypass circ it had on it - but never gave it thought when I had it.
