UH Manor Chemistry Department If short-circuited, car batteries can deliver up to 300A (caution: extremely dangerous). However, according to what the quote above says, you shouldn’t discharge a car battery at a higher current draw than it’s rating divided by 10.
But in an emergency situation, where you need to keep warm, you don’t care about that rate. So, theoretically, a carbatterycan produce enough energy to run a space heater.
So, you would need to install an electrical inverter (a device that transforms DC to AC). Additionally, car batteries have a voltage of 12V, whereas a space heater needs 120V (or 240V in Europe).
And we didn’t even account for the energy losses of the inverter and transformer. We’re going to cover whether it actually makes sense to power a space heater with a car battery.
High current draw puts stress on car battery : The high amount of current your space heater needs puts a lot of stress on your space heater. If you remember what we talked about before, you shouldn’t pull more than 4.5A from a car battery.
Connecting a space heater to it would put the same stress on your battery as cranking the engine continuously (for hours)! Risk of damage: You simply shouldn’t play around with such high current devices.
Cars usually have poor insulation and the heat will quickly disappear. There are some alternatives for keeping warm when you don’t have access to electricity that you need to consider before even thinking about using a car battery.
Usually, they are smaller than regular space heaters, but they are just fine for keeping the temperature up in a car. For heating a home without electricity, the very best way I know of is using an indoor propane heater.
When I reviewed whether toucan use a generator to power a space heater, I also concluded that propane heaters are a safer, more efficient and more durable method to keep warm without electricity. Additionally, it will only keep you warm for around 3 hours until the battery is drained, and it’s dangerous as well (you’re playing with high current devices).
Instead, you should get an indoor propane heater to keep warm in an energy outage. He studied electrical engineering and information technology and decided to blog about heaters after working in the temperature sensing industry.
Press question mark to learn the rest of the keyboard shortcuts Just a general question about using car batteries stored in your vehicle to run space heaters.
What I'd like to determine, based on that usage is the size of the Jacket that I'd need to run for a weekend trip (e.g.: Friday night to Sunday afternoon). Edit: for those of you who don’t care to read through but are curious about the system I’m leaning towards, I plan to buy a Jacket 500 (the newer one has a MPPT input).
Hello everyone, Some friends and I are planning to visit the Ozark national forest in Arkansas around the end of November and wanted to know if anyone knows of some off -road trails where we can camp? Many people who are looking for an affordable, energy efficient source of secondary heating often wonder about the possibility of using battery powered heaters.
Still, if you’re thinking about using a battery powered heating unit, such as a space heater, to provide some additional warmth to your home, you’ll probably be in for a bit of a shock when your searches online return very few, if any, products that suit your needs. Now this doesn’t mean that this battery operated vehicle heaters and the like can ’t be fairly effective in certain situations, but it is to say that they do come with quite a few limitations.
The fact that these units don’t require their own battery to be carted around makes them incredibly lightweight and portable, with most products being made of plastic and weighing only a few ounces. Nonetheless, most are at least fairly effective ways to add some additional heat in your vehicle on those cold mornings or to help defrost the windshield, and some may even be efficient enough to use on their own if toucan ’t afford to pay the hundreds of dollars it might take to fix your car’s broken heating system.
Many hunters, ice fishermen and other outdoors types have long taken advantage of battery powered socks and hand warmers to help keep them warm during those frosty winter days and these products continue to be quite popular today. These combination heaters make use of a small battery, which powers the ignition and fan, while the heat is produced through burning propane or some other fuel source.
Still, it must be mentioned that not all of this type of heater is suitable for use indoors, so it’s always important to read the product information and details closely to make sure. Bottle of propane, making them quite a useful option on those bitterly cold days, or whenever you need some quick, additional heat.
They provide plenty of heat in the small confines of your vehicle’s cabin and can keep you warm in the event of a breakdown. Battery powered hand and body warmers are designed to help those who spend large amounts of time in the cold the ability to stay warm while on the go.
These heaters require the installation of AA or 9V batteries to operate and can provide enough heat to keep your hands or body warm for the majority of the day. A large portable battery powered space heater does not exist.
As an example toucan buy safe indoor propane heaters. It is possible a portable battery operated space heater might exist in the future.
If you stock a number of the propane tanks or have a larger external one toucan provide relatively safe emergency backup heat. Both units have safety features including an auto shut off if they are tipped over or oxygen levels get too low.
A propane heater that is burning correctly creates mostly water and carbon dioxide. The extra water vapor can be an issue if the heater is running for many hours or days.
The highly efficient indoor propane units are designed with shields, but there is still a risk of fire, similar to a plug-in electrical heater. Never place flammable objects near a heat source, especially a propane heater, unless your unit indicates otherwise.
Even if you don't purchase a propane heater, or a wood stove, you need a fire extinguisher. If your home is very tight, and the heater runs for a long time, you may need to crack a window to allow carbon dioxide and carbon monoxide to escape and oxygen to come in.
Using a safe propane heater indoors can create a lot of water vapor. You may have issues with moisture on Windows (condensation) if you use a propane heater in the winter.
This can result in ice buildup, and slippery floors if they are much colder than the air. It is a fan that blows air past a coil with hot coolant from the running diesel or gas engine.
So the heater is a combination of a fan and the gas or diesel cooling system. Yes, toucan purchase 12 volt resistance heaters that create about 150 watts of heat and draw about 20 amps (so it needs a 20amp fuse).
That means you would need 100 to 500 car batteries to heat a home with electricity for a short period and more for multiple days. It is not practical to use batteries to power resistance based heating systems.
Battery powered, heated clothing is available from Dealt, Bosch, Akita & Milwaukee and many other providers. Akita makes some heated clothing, but we don't recommend them based on other reviews (we have not tested them ourselves).
LIP based batteries are great, but you would need about $20,000 worth of them to heat a small home for a few hours. Also, LIP has higher risk of bursting and starting on fire, which makes them a poor selection for resistance heating.
The alternator charges the battery and runs the electronics in the car, including the 12 volt resistance electric heater. If you are not careful setting up the power for a heater that uses 12 volt car batteries, it can easily cause a fire.
Further the amount of electricity needed to create space heating is significant. Using a 500BTU 150w 12volt resistance heater would require 80 to as many as 400 batteries to provide heat for just 1 day.
So as we noted, there is no such thing as a battery operated home space heater (yet). If you see one advertised, it is probably a scam or mislabeled product search result.
