TARM 502 Circulator battery backup

jjclc,

Good idea for a string. I am in a similar situation, using a generator for backup. I also have been thinking of a battery system for my circ's. I have been looking at solar to charge the bank, but have not moved on the idea yet. I will be very interested to see what the folks in the know will have to say about this.

welcome from another newbie.

What has been commonly suggested here previously for these situations would be to look around online and find a computer UPS (Uninterruptable power supply). You would connect your pump and zone valve controls to the UPS, and in the event of a power outage, it would provide power until you could hook up your generator and recharge the batteries. Instead of using the batteries that come with the unit, you could use a separate set of external batteries to meet your demands.

I dont have personal experience setting this up (yet), but there are others here who have. Shouldnt be too difficult to get going, I hope!

One of these would work well but it is overkill to run a circulator.

I ended up building a system for mine using a 300 watt pure sine wave inverter, a relay, a battery charger/maintainer and the battery from my boat. It runs the circulator and the boiler in an outage if I don't get the generator running. Should be enough power to complete a burn cycle but I have never run it that long.

Would like to connect a battery back-up system to run the circulator pump in case of power loss. Normally during a power outage, I use a generator to power the entire house, but would like to have a battery back-up when I'm not home to start the generator.

This was bought as a back-up starting power for the sailboat. It will run the circulator and thermostats easily, but it is a low end unit and the circulator does not sound happy. I've been told this has something to do with sine waves, which means nothing to me. But a better quality unit would have worked fine.
