Not sure if anyone covered this, but here's a suggestion: Run the furnace only when you need to during power outages. The cycling on and off of the furnace takes energy. Also, the inverter uses a bit of energy as well even when in idle. So in a power outage, run the furnace in long increments only when you have it manually on. When you are not running the furnace, shut off the inverter.

As I mentioned in another DIY HVAC Guy video - thinking about how to not draw power running the inverter until it's needed is possible. Most thermostats are demand contact closure (advanced ones have more conductors but the principal is the same). Getting a modern heater to work with an inverter battery backup is not hard, but takes a bit of thought. It could be hard-wired in with a few relays: one to detect a power failure reconfiguring the connections for direct inverter control, and anoher to handle low-voltage switch-over (short the heater-facing demand contacts, present the thermostat contact closure to an inverter enable control circuit - probably another relay driven by a low curent detection circuit with a hold-up for the controller's logic time-out). Look at simple timing/delay relays... like the venerable TE-8816U. A brave and skilled HVAC tech should be able to figure this out in no time.

In order to know while discharging the battery you need a battery monitor. Another video idea would be to use a cheap Harbor Freight or other 100 watt solar panel to maintain the battery and charge it fully (even on a cloudy day) then seeing if your battery stays above 50% on a cold night.

So make sure if you have a raw lithium battery it supports a temp sensor disconnect. The other issue is making sure you don't recharge the lithium too fast from alternator - you can burn one out quite easily as the internal resistance of lithium is quite low thus allowing it to suck in tons of amps during a recharge cycle. Making sure a DC to DC charger that can regulate the current.

Inverter efficiencies are 95% when under full load but as load is always sporadic, over all efficiencies are often stated as 50%. The problem is that the inverter will still draw power when idle and unless it's really record keeping cold, your furnace will spend most of the time just being idle.

Many cars will not put out enough for a 550 watt load if there is a low idle, e.g., 600 RPM, same for some pickup trucks as well, though some will have a mode where the engine increases to an idle of 1500 RPM to deliver more power. Though even without that, if the duty cycle of the heating is short enough, then the alternator will quickly top off the battery after a heating cycle ends. On my crappy Mitsubishi, it will do close to 450 watts before the voltage drops to about 12.4V (using a current clamp on the alternator while operating without a battery while idling. During that time, engine load also increases from 20% to 29%. The most common alternator found in the average V4 (2 to 2.4 liter engine) car, will be 125 to 150 amp units that will output about 14 to 14.5V. Many are designed to offer the bulk of their power at lower RPMs, since it is likely for modern vehicles to spend much of their time between 1000 and 2000 RPM. PS if you are running something extremely demanding, and you start pushing the engine to speeds like 4000RPM to maintain voltage, then you are likely to destroy the diodes and other passive on the alternator, as you are likely pushing them well beyond their limits. Issues like that are common for people who try to do things like run a 2000 watt speaker system in their car and show off to their friends by blasting music (sadly still a common jerk move that is done here in NY). Beyond that, a 125 amp alternator is not designed to deliver 125 amps nonstop, instead they are more designed to handle up to around 75% of their rated capacity for more sustained loads.

@@Razor2048 I think it is important to note that we're talking about running the blower and electronics of a gas central air furnace from a car battery removed from your car, not of running it all from a car engine through the alternator. The power consumed by the electronics can probably be disregarded and if the blower is a 1/4 hp induction motor, we're talking about 186 watts but only for when the blower is running which would not be all the time. A typical car lead acid battery holds 1,323 watt hours but you really don't want to deep cycle lead acid batteries, even deep cycle batteries loose 5% of their lifespan with a single deep cycle so you really want to maybe use 25% of the battery's capacity, 50% if you don't mind some damage to the battery so we're talking about 1.8 hours to 3.6 hours, however even though inverters are 95% efficient under full load, they still consume power when under no load so they are considered to be 50% efficient under sporadic loads which this is hence you can expect 0.9 to 1.8 hours with a single average car battery depending on the duty cycle required, more if you elect to require refurbishing or replacing the battery.

Hi Dave, thanks for all the effort you put into this video. Ideas like this are worth their weight in gold when power goes out and the house is getting cold rapidly; using items the average person already has on hand to possibly save your life with. Your furnace looks small, I'm guessing 50,000 - 60,000 BTU input? A 100,000 BTU unit would probably use a proportionally higher wattage. I have been interested in backup power since the early 1980's so, have learned several lessons the hard way during extended outages. A car 12 volt system is one source of limited backup power, in the past, I have actually made up inverter kits for friends to run a few lights in the house off the car battery. Some limitations to note: I don't recommend trying to pull more than 400 watts (about 30 amps) from the system while the engine is running, that's about the safe limit with the engine idling. Car alternators have a rated output with the alternator shaft speed at 5,000 rpm. At idle, the shaft speed is about 2,000 rpm and, with no overload protection, the alternator will overheat itself trying to keep up with high load currents. Car batteries have a very short life when used with a power inverter with the engine not running. They are designed solely for short term high cranking current, discharging them more than about 30% of their capacity (12.4 volts with no load) (this means 70% of the capacity is still left) will significantly shorten their life. A Marine Battery is a better choice, as they are a compromise between starting and deep discharge (but not more than 50% (12.1 volts no load). With those low cost 12 volt power inverters, I have regularly witnessed huge errors in the front panel readout. Also, I have had some inverters destroyed if turned on while the engine is being cranked so, I would recommend disconnecting the inverter from the battery while starting the engine. Of course, when using your car for power, care must be taken to prevent carbon monoxide from getting into the house and ideally the garage. As a heat backup, I would recommend a small (10,000 btu) ventless wall heater, placed in the center of the house. They don't require electricity and burn cleanly, although do consume oxygen. I used this type of backup for 3 years in an old drafty house that was built in 1900. In a super insulated, tight (no air leaks) house, the ventless gas heater may not be a good option.

@@ryanhealey239 Hey Ryan, I can probably steer you in the right direction. To begin with, I made a career of designing high reliability communication transmitters, receivers, and power supplies so, inverters are very familiar to me. In 2018, I decided to put together a whole house off-grid solar system on the cheap. I ordered all the stuff off of eBay and began the learning experience; would low cost Chinese components do the job? On the subject of inverters - No! I ordered 10 different models in several different wattage for a 24 volt battery system. All 10 inverters failed for one or more reasons just trying to use them in normal, non-abusive, real world setups. Since your life depends upon these inverters when you are using backup power, the quality has to be there. I ended up going with an inverter that is commonly installed in yachts; the Magnum Energy, MagnaSine series. This is a 24 volt, 4,000 watt inverter that uses a traditional laminated iron E/I core 60 Hz power transformer. I have used it to power the house for 2 years now and haven't had any problems with it, even with it taking some accidental abuse. You may want a lower power inverter or hope to spend less money (that one cost $1,250 in 2019). You do get what you pay for though. What you want to look for is an inverter made in the US and with a 60 Hz power transformer, which makes it more rugged. Once you figure out the wattage you want and input voltage, you can go to Amazon and look at reviews for that size inverter. You mostly want to look at the 1 - Star reviews to get an idea of the problem areas. A good inverter will have a large overall number of reviews because, people have determined the unit to be one of the best bets. Next look at the percentage of 1 - Star reviews, it should be under 10% (Of course, the lower the percentage the better). Of the problems mentioned in the 1 - Star reviews, are these problems you can live with or, not worth the gamble? 12 volts is nice because it is based around the system used in cars, boats, and RVs (making it very popular for accessories) but, it's quite limited due to the super high battey currents needed. If you need more than 1,000 watts, it's best to go with a higher battery voltage system (24 and 48 volts). The highest wattages are best handled by the 48 volt system, which has 1/4th the current of a 12 volt system. In anticipating your question: Why didn't I just design my own inverter? Not practical, just buying the individual components would cost several times more than buying a completed unit. Also, I don't have that much free time. If I devoted 100% of my time to such a project, I may be able to have a practical working unit in 2 years.

One type of heating system that can last for many days on battery are the super old fashion steam based heaters. Since the battery is only used to open a damper flap during the power on cycle, and then the remaining power use is for the temperature and pressure sensor, as well as keeping the gas valve opened. Since there are no fans, some units can have a steady state consumption of 5-10 watts. Furthermore depending on the steam based system, and the control box used, you can use straight DC power if you bypass the bridge rectifier to improve efficiency.

I have a small generator, but the car/inverter thing is a great backup. And certainly to learn how to run the freezer without electricity or fuel will be a plus.

I'm in VA. During Hurricane Isabel I had no power for 5 days. I ran my 21 cu ft freezer with a cheap HF 700W inverter for 5 days with my F150 idling. It used a half a tank of gas. The freezer draws only 137W if you put it in "Sabbath Mode" (no defrost). I froze jugs of ice to transfer to the fridge, which uses more power and which didn't have a way to defeat the defrost cycle. I've since moved on to a solar storage system, so I can lend my inverter to a neighbor next time.

100%, however the inverter allows for effcient, quiet power. as much as you need exactly when you need. Use the generator to charge up the batteries - it can run full speed and put all of it's generated power into the battery instead of just running doing nothing most of the time when your freezer is idle. Basically you just go out every say 6 hours and run the gen for 30 min.

Most large Chevrolet pickups, and Suburbans (2500) have connection terminals that are already hardwired for connecting inverters under the hood located near the battery, and fuse box. They are more for powering auxiliary power supplies for campers, and trailers, while you are driving down the road. The extension cord that you use should be heavy gauge wire. (The orange extension cord with a black stripe). You can also hardware in an electrical "inlet" receptacle to the furnace, so that the power cable will work with either your generator, or inverter.

This is An awesome video . Really and truly , a car battery is not really good to use to run the central heater furnace or other loads off an inverter because it’s uses almost all of that power from the battery to start the vehicle and the alternator puts the charge back in it before it kills the battery 🔋. Like the other commenter said below , use a 12 v deep cycle , AGM or best yet 2 x 6 volt golf cart batteries connected in series for 12 v with a lot of amp hours 100 - 250 AH , not CCA as in car batteries . You can go this route as the car can charge them or get some solar panels to do that . Keep it up and running and May the solar be with you .😊😊

A few thoughts: Car engines aren't design to idle for extended periods of time. For one, there's the danger of CO buildup if it's idling inside a closed space like a garage. For another, engines can overheat without sufficient airflow, even in cold temps. A kilowatt is an awful big load to place on a car's charging system. Just by way of example, the 4-banger Taco's alternator is rated for a maximum output of 80 amps @ 12 volts, which is 960 watts. Don't forget that the alternator has to keep the truck's battery charged, the ignition firing, the electric fuel pump running, and all the other electrical systems energized. Also, regular car starter batteries are optimized to provide a ton of current for brief amounts of time in order to crank the engine. If you try to treat one as a deep-cycle battery, you'll dramatically shorten its lifespan--especially if you manage to drain it completely. Adding the ability to connect your furnace to an auxiliary power supply is a good idea in the case of a power outage. (Assuming of course that the power outage hasn't affected the stations that pressurize the gas in your neighborhood too.) I'd go one step further though, and invest in either a big deep-cycle battery, some sort of generator, or both.

@@terryharris3393 There are high frequency pure sine wave inverters and low frequency pure sine wave inverters. Most, if not all modified sine wave inverters today are high frequency. Check out the Aims line of inverters. They sell all three types. A low frequency pure sine wave inverter rated at 2000 watts continuous has a starting current rating of 6000 watts due to the massive transformers used and can maintain that current for up to 10 seconds or more. A high frequency sine wave inverter rated at 2000 watts only has a peak current of 4000 for less than 2 seconds typically. For this reason, starting inductive loads like motors are less troublesome for low frequency inverters. I use a 2500 watt Aims LF (low frequency) inverter to run 2 household fridge’s and 2 medium chest freezer’s along with other lights and miscellaneous (all at the same time) when our power goes out. And since I live on an island, it happens quite often in the winter time. Every high frequency inverter I have used fails under heavy starting load even though it may be rated at twice or three times the wattage of a low frequency inverter. The low frequency inverters are built to withstand heavy starting and running loads. They do consume more watts in standby but you just factor that in when sizing the battery bank and yes, I have two trucks with the battery charging capabilities to my inverter battery bank. My system is designed to handle up to 200 amps of charging capability since I have no guarantee when my power will come back on.

In my experience, I have seen a lot of people claim that their lead acid battery was charged in 2 hours. But unfortunately that not how the chemistry works. After about 2 hours the battery will have what's called a surface charge. It may read 12+ volts on a volt meter, but as soon as you start drawing current it will drop fast. The charge doesn't have depth or the umpth that it would if you let it do a full charge cycle. A full charge cycle for most lead acid batteries is like 12 hours. And that can vary depending on how big your battery is and how fast your charger is. 100AH battery with a 1A charger will take longer than a 10A charger, but that absorption charge time is a must after the battery reaches saturation at around 14.4 volts. A starter battery is designed to deliver a high amount of current for a rather short amount of time. Enough to crank the engine and then it will recover while driving around. The actual amount of energy that is consumed by the starter isn't a lot. Also, I've found that letting a starter battery drain below 10V causes irreversible damage to the battery. Let it stay below 10V, like when leaving the headlights on for an 8hr work shift...you might be able to get your battery to recover. But rarely a 2nd time, and never a 3rd.

I totally agree with what jbdragon3295 says. You do not need to run your furnace continually during a power outage. You also don't need to keep the heat at your normal room temp either. Running the furnace every couple hours and at a more conservative temperature will add hours to your total runtime. The same with your refrigerators and freezers. A fridge only needs to run a cycle every 4 hours or so and a freezer that is well insulated can be charged up a couple times a day if that. I am speaking from experience with hurricane Fiona here in Atlantic Canada. Something I found out though was that my Samlex 2212 inverter has a power save mode where if no load is connected, it will pulse its output until it senses a load of a certain wattage. It will then turn on fully and go back into power save mode once the load is disconnected. However, my oil fired forced hot air furnace did not like the pulsing once the furnace had turned off after a complete cycle. It confused the furnace controls and it started behaving erratically. I turn power save mode off before connecting up the furnace or plug in (3) 40 watt LED bulbs (they're in a fixture) into the output of the inverter to act as a ballast for the furnace load.

I've been looking into this for my home, and have discovered a few things that might be of help to people. (1) You need to be able to connect your inverter to your furnace quickly, and be sure you're not also connected to your electrical panel. If you do not disconnect from your electrical panel, you run the risk of electrocuting a lineman working on the electrical grid, and if the power comes back on you will fry your inverter and heating system. It's also illegal. In the first video, the panel was disconnected from the heater on the inside by undoing the heating connections. You would have to do this every time there is an outage, and then reconnect, which is a lot of trouble. You'll also likely be working in the dark with flashlights - not an ideal situation for inexperienced homeowners. It would be much smarter to re-wire your on-off switch to a double pole double throw (DPDT) switch with three positions - on, off and on. This type of switch will have 6 wire connections - 2 for the hot and neutral coming from your electrical panel, 2 for the hot and neutral coming from your inverter or generator, and 2 in the middle for the hot and neutral going into your furnace. You would wire your service panel line into one position (say top), your inverter line into the second position (say bottom), and your heater into the middle position. When the switch is up, the middle heater line will be connected to the electrical panel, and when the switch is down the heater will be connected to the bottom inverter. The panel and inverter will be isolated from each other in any possible. In the middle position everything will be disconnected just as the switch is now. The ground wires can all be combined inside the box (if that's where they are). It's much cheaper to buy a simple dpdt (dual pole dual throw) switch than to buy a separate inverter adapter plug (which cost about $80 or more). You have to be sure that your switch is rated to cover the voltage and amperage that you'll be using (in the US at least 120 v, and 15-20 amps). You'll also need to add a electrical pigtail coming out of the switch to plug into the inverter line. I am waiting for my parts to arrive to make this modification, as my heater is hardwired into my panel with no plug. (2) I understand that some advanced furnaces will check to make sure that the circuit has a neutral-ground connection, which occurs in the electrical panel. Most inverters and generators are made to plug into an electrical panels and so do not have their own neutral ground connection - they are made to rely on the electrical panel's connection, and you don't want to have multiple neutral-ground connections on your home circuit because your protective circuit breakers may not operate properly. These are called floating ground inverters/generators. If your heater checks for a neutral-ground connection, it will not operate correctly with a floating ground inverter/generator. Usually, the blower will not come on. You will have to bond your neutral/grounds in order to get your heater to work when using a floating ground generator or inverter. You can do this by plugging in a neutral-ground cheater plug into one of the other plugs on the inverter or generator that shares the same circuit with the other plug that you're using for your furnace. Some people instead put a cheater plug in a power strip which has a circuit breaker in it, plug the heater into the power strip, and power line from the powerstrip into the inverter line. That seems like a better solution than blowing a fuse in your inverter if you have a ground fault (if it works to avoid blowing a fuse). You can buy or make a neutral-ground cheater plug pretty easily - there are videos talking about this. (3) I think it's a really bad idea to run your car battery down at all to run your furnace for a cycle or two. Car batteries are absolutely terrible in deep cycle use. They are made with very thin electrical plates to provide a ton of current to start a car, and need to be promptly recharged after starting. Running your car battery down below 12v is a sure way to shorten its life, and someone will not watch it carefully enough and will run it dry. Car batteries may only last 10 cycles if run down. Instead, start your car before running the furnace to use power from the alternator, and hopefully keep your battery fully charged. That way you can start your car to get more gas and won't kill your battery. (4) Rather than permanently installing your inverter line in your car (which is problematic if you remove your inverter and have the 12v positive and negative dangling around for a likely short which would be catastrophic), it might be better to have a short cable with battery clamps on one end, and inverter ring terminals on the other end. That way you can attach the inverter under the hood when you need it (rather than keeping your door open to run your line). The problem is finding or making the cable because inverter ring terminals to battery clamp cables are not easy to find. And it's very important that your 12v cables be good quality - you may be running 70-100 amps through this cable for long periods of time. So you need a thick copper cable, not some junky copper clad aluminum cable like many jumper cables are made from (which are made for very short term use). Many of us won't have the tools to make a cable like this. So I haven't figured out this part of the problem yet. I have a good, short, thick cable with battery clamps that I harvested from a dead lead-acid jumper pack, but I don't have a hydraulic crimping tool to add inverter lugs. I need a friend with a hydraulic crimping tool! (5) in order to avoid a spark when hooking your battery up to your inverter, which is both dangerous and bad for your equipment, connect the last leg to your battery through a resister or tester light to let the capacitors in your inverter charge up before making the last battery connection. This will avoid the spark which can be damaging to your inverter or battery, and you run the risk of an explosion when there is a big spark near a car battery which puts out some flammable gas. I hope this is helpful.

The car will run for a very long time as most alternators can produce 1000+ watts of power, some modern vehicles much more. And your vehicle stays more or less at idle speeds, consuming little gas. Also much quieter than a generator. And no worrys about old gas or getting it dragged out of the garage and hoping it will start. Just always make sure the vehicle is outside when running.

My family was stuck without power for 7 days after a fluke snow storm. I had a full tank of gas in my Escape and 10 gallons to spare. I ran some lights and the heat for just over 6 days for my house from my vehicle. I had just ran out of fuel when the county cleared the road to my house. I was able to get out and get fuel in town. As I was driving up to the house the power came back on. The issue I had was my battery and alternator both died within a few months but we didn't freeze. I bought a generator the next week. Two weeks later we were out of power for 13 days due to lines being down from high winds and ice.

I think this is a great idea. I also think there may be a slightly involved way of extending the run time of the inverter, battery and furnace. If you were able to have a simple mechanical thermostat (set close to the homes thermostat) that could close the power switch on the inverter, using a 12v relay from the battery power, that inverter wouldn't have to run the entire time in between heating cycles. It could simply close the circuit to the inverters power switch using this 12v relay controlled by the mechanical thermostat. Here's the involved part. Once on, you really would want to hold the relay on with a (holding circuit) say until the furnace cycles completely off. This means the inverter would be off in between heating cycles. The mechanical thermostat would start your inverter and once running the furnace would have to keep it on by holding the relay on until the homes heating cycle finishes and the furnace and blower are all the way off. This should extend the time considerably. Hope this isn't too complicated. Lol

I see you did a follow up and I hate to leave off uncertain information on a previous topic. After asking around about the potential damage and what was recommended to prevent damage from surge or lack of voltage I finally got the device name. It's called a (power conditioner) and made in California by a company called Furman. It's not to be confused with a simple surge protector because it cleans up the power signal and puts out a consistent 120v. The price can vary from $23-$74.99 and is highly recommended for use when running off generator and battery powered systems. I'll see if I can dig up the link and provide it in a minute.

Some of the little $200 to $250 portable battery/inverter combos like a Bluetti EB3A would serve the same purpose at the furnace and run it stand alone for an hour or two per full charge. The nice thing is that they're very portable and can be charged either by a 12V battery including car adapter, solar panels, or by an AC setup like you have with a separate inverter or generator. This could extend the runtime indefinitely and give you a good device that can show you a 0-100% state of charge to know when/if further action is needed. One for the furnace and one for the fridge could be ideal and possibly the cheapest disaster insurance you can buy.

Regardless of the run-time on your example setup, I still think this is a great backup, especially if you factor in something like the "solar generators", or rather, the units that are the combination of battery and inverter. The key factor in your setup is the capacity of the battery, not the ability of the inverter, so adding more/larger battery capacity can extend the runtimes. There are literally hundreds of options out there with a huge range of capacity... Jackery, Bluetti, Goal Zero, Renogy, etc. If someone does not have a gasoline/propane/nat gas style generator, these are extremely simple units for them to store, keep charged, and operate.

Nicely done again! when you say the furnace ran for 6 hours I assume you mean that was the total elapsed time, including when the furnace was off during its normal cycling? So if it 'ran' 6 hours, it was heating for maybe 10 minutes, off for 20 minutes.... 12 times total = 6 hours? IF your power goes off and your goal is to keep the pipes in your house from freezing, you can turn your thermostat down as low as 50F- That will make your furnace run for much shorter intervals, allowing one battery to keep the house at 50F for a much longer time, than trying to keep the house at 70F. Another thing you can do is close all the heat vents to rooms that have no water lines running to them. For example, pull the mattresses off the beds in the kids room, bring them into the master bedroom (or family room) and close the doors and vents off to rooms you dont need until the power comes back on. Again on this video people are suggesting its better to get lithium Ion batteries than lead acid deep cycle batteries. That is not true. For the same energy storage (amp hours or watt hours) Lithium Ion batteries will cost 2 1/2 to 3 times as much - for the same price you can buy three times as many lead acid batteries, or you can replace the same capacity three times over the life of your house, compared to buying one lithium Ion bank. If a lead acid deep cycle battery is rated for 100 A-hrs, the you can get 100 A-hrs out of it without degrading it. The reason lithium ion batteries are used in cars and cell phones and laptops is because they are about 1/3 of the WEIGHT - that is important for things that you carry or things that move. It does not matter when they are sitting on the floor next to your furnace.

One good thing to note is make sure your battery health is at 90% capacity or better / do a load diagnostic to see this- A battery that is within the 5 year of age is good, - and you have a alternator that is relatively in good shape and not to worn out. Remember heat and charging at high amperage wears out the brushes and slip rings of the alternator.
