how much electricity does boiler/circulators use???

[BoilerMan]

Exactly what I'm talking about! When I install submersible pumps, I put a secondary check valve on the pitless, just before the 90 degree turn out of the casing. No other check valves should be installed inside the house. This way there is always pressure on the pitless' Oring which will make it last the life of the pump (typ 20 years).

i just looked down in utility room. it looks like a i have a circulator just above propane boiler and its running (i have boiler propane on aquastat so it is not being used while i have wood boiler going, but circulator seems to be on), also saw two more ciruclators in primary loop that seem to be on even though i have no zones calling for heat at moment (or at least i think). so i guess its possible 3 cirulators at approx 80 watt 24/7/30 for month added up to 172kwatt for month, thats alot of power right there, and when i add two more circ by boiler adds another 115kwatt. so its seems these circulators are for sure some of my high electric use. i know the 2 by boiler run 24/7, not sure if these ones i see on primary loop those 3 run 24/7 or not, not smart enough to know excatly works those or not.

ok may have found my culpret. i looked at the 2 circ by boiler i thought at first they were 2 talco 007 but only one is 007 the other is a big 0011-BF4-J
wonder what power rating is on it., i'll bet it high and it runs 24/7 primary circ from boiler to basement primary loop. i got it with system used when i bought it thrown in, electriction told me it was a little over kill but never thought about power use on it.

ok the 007 is 80.5 watts, the 0001-bf4-j is 202 (115volts x 1.76 amps), so just for those 2 circs that run 24/7 its 282watts/hr or approx 204kwatt/month so i guess i definetly have to swat the big one out for sure, then maybe a few of the smaller ones and that will give me a big reduction in electricity. also i plan to add storage and if i do that and have independent circ to run storage when up to temp i can shut them off and only have an efficent circ run storage.

My B&G PL36 uses 235 watts. It's a big pump. Perhaps bigger than it needs to be. It has lasted 5 whole heating seasons though and doesn't turn off from Dec. to mid March.

With storage you should be able to eliminate the space heaters also?

My old oil boiler had a big Bell & Gossett circulator pump. It only ran when the boiler was on, but I would guess it was between 1/4 and 1/2 horsepower based on its size.

When I had the piping runs split to zone the system, the plumber replaced that pump with two Taco 007 pumps, also running only when the boiler was on. My electricity consumption during the winter months dropped by ~100 kWh.
