Barb Posted March 2, 2023 Share Posted March 2, 2023 Hi all, I had a 4 day power outage recently here in Michigan. I had battery operated air pumps that worked great. And I covered my aquarium to try and retain heat. But it got too cold for too long, and I lost half my fish. I know that you can buy large battery back ups now, and was wondering if anyone had experience using one to power aquarium heaters? Does anyone have any experience with brands that might make someone either want to get that brand, or want to avoid it for that purpose? thanks so much!

Jackson Posted March 2, 2023 Share Posted March 2, 2023 Maybe a small honda generator . 1000kw . If your in the situation to have one . Can't where I am at now or I would . 2 Link to comment Share on other sites More sharing options...
Tommy Vercetti Posted March 2, 2023 Share Posted March 2, 2023 I have used the small Honda generator this way. Works good and you can use it to power other things. 3 Link to comment Share on other sites More sharing options...

Running a generator to make electric heat is incredibly wasteful. The generator at best converts about 30% of the energy value of the fuel in to electricity… an UPs unless you go for something like an ecoflow delta pro at $3,600.00 is going to run out of power within an hour if you try to run a heater…… long and short of it, a battery back up sufficient to keep your tanks heated will run you over a grand. Do you want to budget that? alternatively, running a camp stove to heat water and judiciously adding it to the tank would be pretty cheap. I would probably use soda bottles and heat water and pour them in the sodabottles and float the bottles in the tank, but you will need to keep an eye on the tank… If you can stomach a grand or two for battery back up suitable it is doable…. Powerqueen makes nice Lithium Phosphate batteries that are attractively priced considering their cycle life span,(ie you can deplete 100% rated amp hour capacity daily for 10 years and still have 80% battery capacity…). A 200 amp hour battery stores roughly 2 killowatts of usable power for around $600.00. Excellent bms built in to the battery. Excellent amperage draw ability… battery weighs about 56 lbs IIRC so easy enough to bring somewhere with power to recharge or buy solar panels to bring outside to top off… The battery back up with inverter has major advantages over generators. They are silent and dont produce carbon monoxide. You can keep them inside and need not fear theft like gas generators..,. More likely 1,000 watts. 1,000 killowatt generator would be a beast! My bad .... 1000 watts Link to comment Share on other sites More sharing options...

How would you transfer the power to the aquarium ? Heater and all . Looks like a car battery type hook up . Be nice if it just had some plugs .

Barb Posted March 2, 2023 Author Share Posted March 2, 2023 Thanks to you all! Such great information!!! I’m thinking I’ll get a camping stove as suggested. Barb Link to comment Share on other sites More sharing options...
Matt B Posted March 3, 2023 Share Posted March 3, 2023 I've found there are many options. Not all work for everybody and their specific situations, that's for sure. Nothing is really cheap, efficient and easy. Sources of power are what they are. We loose power often enough, that we now have a generator for us and the creatures in the glass boxes.

You can plug it in to a BEV car charger, hook up solar panels etc.. It is also 3,700.00roughly. But it is largely plug and play. You dont need toshop for other parts and do wiring…. the Powerqueen is just a battery. You would need a suitable inverter, battery charger, and do the wiring. You would need pretty big cables from battery to inverter, and you would also want a large main fuse with a very high ampere interupt capacity. (AIC rating) that last point is crucial as a dead short with the kind of capacity this battery has could be pretty specatucular, though the BMS might well have it covered. I tend to like backup safety and the fuse is pretty cheap safety in the grand scheme of things. The Ecoflow has a true sine wave inverter. You could get a modified sine wave inverter that would work just fine for aquarium heaters and air pumps and filter pumps and it would be much cheaper than the true sine wave inverter… I want one.... lol .... I have great plans where that would be useful Link to comment Share on other sites More sharing options...

You can combine two units to give split phase 240/120 with special combiner cord units. Nicely portable with built in wheels and telescoping handle… but kinda pricey… While your doing the math ..lol. What could you run, say for lights and computer for how long ? If you don't mind this is useful info . Link to comment Share on other sites More sharing options...

How you use it affects its power use considerably.. a Kill A Watt meter allows you to plug the device into an outlet and the item you want to measure into the meter. It then logs how many killowatt hours it consumes for the time period measured. my dehumidifier is plugged in to a meter. It consumes 347 watts when running. That is its connected load The duty cycle is how much it runs in a given time period. It is reporting it consumes 70 kwhrs in 708 hrs of time That is roughly 2.4 killowatt hours per day. 100 watts per hour. So apparently I have a little less than a 30% run time on the dehumidifier… because I run the dehumidifier in my well insulated bedroom the temp of the room stays around 73 degrees as the water vapor from the aquariums condensing on the coils liberates a fair amount of heat. As such, the aquarium heaters rarely run. 2, 29 gallon tanks and 20 gallon tank. We use roughly 10 killowatt hours per day to run everything we use per day in our home. A kill a watt meter can really help you figure out your power needs. This the critter ? Would be helpful to see what I will need for electricity. https://www.amazon.com/Poniie-PN2000-Electricity-Electrical-Consumption/dp/B0777H8MS8/ref=sr_1_6?crid=PEBC3X7TJIJ&keywords=kilowatt+meter&qid=1677811050&sprefix=%2Caps%2C94&sr=8-6 Link to comment Share on other sites More sharing options...

Barb Remember to use it in a well ventilated space. With no electric, you can’t run your stove vent hood, so you must run a fuel operated camp stove outdoors (or at least in an open garage).

Sharon M Posted March 3, 2023 Share Posted March 3, 2023 You can use water from your hot water tank. Fill bottles up with the water and float them. Link to comment Share on other sites More sharing options...
RockMongler Posted March 3, 2023 Share Posted March 3, 2023 From the big freeze Texas had 2 years back, I was able to get through that with no losses just using sleeping bags to wrap my tanks, and battery powered air pumps to keep the gas exchange going. I was only out for 3 days, and all my fish were cool-water at the time, however. For future power loss here in Texas, I got a 2350 watt inverter-generator that I can use to keep fish tanks running in the event of normal powerloss, alongside things like my fridge and being able to charge devices. I still keep my battery air pumps around as well for shorter power loss/giving the generator a break. My future plans, more for hurricane related power loss, is to go for solar generators. They are basically large batteries with build in power inverters that allow you to output energy like a regular gasoline generator, that are also designed to be charged by solar panels.

They can be small like this one, and you can even get ones big enough to power a small building. It's another option besides just fossil fuel powered generators or standard batteries to keep our systems running when the grid isn't functioning. I think they are going to be more expensive up front than gasoline generators of similar output, but are likely to need less long term maintenance (no need for fuel, no need to worry about things like oil changes). My use case for one is to charge with solar when I can, and charge with the gasoline generator when I can't, so I don't have to keep the gasoline generator running as much, and can store the energy it's creating for later. 1 Link to comment Share on other sites More sharing options...
