Best way to power device on outtage
Hello there,
I have a situation where I must power my recirculation pump whenever there is a power outtage and I need to run it for atleast 5 hours or so - the more the better. Pump is 45w and I've calculated that I would need around 960VA UPS to power it up for around 2 hours and if I would buy an UPS that could power it for let's say 5 hours it would cost be alot as the budget is tight for the moment. Then I thought about a generator but realised how do I turn it on when there is power outtage, because most of generators are started by pulling. I need a solution that would start powering the device by itself, would power it for atleast 5 hours and would'nt cost me more than like 150euros, I don't know if it's possible but I'm open to any suggestions.
Thanks.

One thing I have done is tie extra battery capacity into a UPS power supply. Most computer UPS power supplies have a small internal sealed lead acid battery. Open the case and extend the battery wires. Then connect them to a larger battery.
The big drawback is the limited charging capacity of the UPS. Where the UPS may be able to recharge it's small internal battery in a few hours it could take a day or more depending on the size of battery you attach.

The recirculation systems I have been around do not need power to deliver hot water to the tap during a power outage, it just takes longer for the hot water to get there and wastes a little water.
