Have been searching on here for a while for a backup system. I just need it to run the boiler circulator in a power outage which happens frequently here.
Here is what I have a 008 Taco pump which is .87 amps so for easier math 1 amp which is 120Watts
If I were to load the boiler and leave to work I would like something that would keep the circulator running for up to eight hours. I am looking for an inverter/charger that I can hook up to batteries that would be available at lets say NAPA so probably not a true deep cycle battery and I would like to run 12 or 24V
So far the least expensive inverter/charger I have found is the Freedom HF 1800 by Xantrex @ 549 this appears to have battery sensors, smart charging, automatic transfer from utility power to DC backup (batteries)
How do I figure out amp hours @ 12Volts so I would know how many batteries I would need to get the 8 hours run time for my circ pump?
Does modified sine wave affect taco pumps? they are quite a bit cheaper than pure sine wave units and I am not wanting to run any equipment other than my boiler
and another thing, my plan is that I would never start a fire if my storage tank temps were high, so I planned on using the tank for a "dump zone". I am thinking that to overheat the boiler I would need the circ pump to fail or start a fire when I have no business starting a fire like loading the boiler when my storage is completely charged?? Does this sound like a safe assumption?
thanks for any help
