convert natural gas water heater to electric

Thanks very much for this very informative article. Warning! Great leading questions. Note that I heat my home with electricity too. I removed the gas burner and mounted a dishwasher heating element in its place. Learn more.Ground Source Heat Pump Rebate—Rebates for installing small and large ground source heat pump systems. Total cost of conversion O$ Old extension cord and free burner and wire from recycle yard. It is probably about equivalent to an electric on demand system with a preheating tank. I’m not sure what the typical usage is that manufactures assume to determine their EF values but I suspect it’s in the ballpark of 2 full tanks per day. Also, a hot water tank is a closed, pressurized system with only a water inlet and a water outlet. (But not sure I had one of those, so…) I’m not familiar with propane hot water tanks but I assume they would be virtually identical to natural gas ones with the exception of the burner itself. It’s only necessary that the water temperature be raised to 60°C at least once per day. Hi John, A great deal of the heat disposed of in the shower waste water could be recovered to pre-heat cold water entering the tank. Used the same method you suggested but instead of using a coil I made a metal cap and drilled a hole in the top and attached a 1500w heat gun. I have two forced air furnaces to heat the rest of the house and do all of the air conditioning. tank to allow the 75watts to heat sufficiently for 20 hours recoverytime. High risk groups are the elderly, smokers, the immuno-compromised and those with chronic respiratory illnesses. My system is of a Natural Gas Boiler with a Water Maker. Reach inside and pull out a spiral shaped length of metal. It is a nice conservation feedback system. The result is that the element puts out relatively constant power at a particular setting. So keeping the heat generated by the resistance inside the chimney space without incurring significant heat losses to the exterior is critical. Save my name, email, and website in this browser for the next time I comment. A lot of people are commenting on the air gap being an inefficient transfer medium. They are all over 90% because the elements are actually in the water. So instead of a stove element I said I would use a light bulb, after all its merely an oversized easy bake oven right? Effectively this would allow the tank to spend more time at a lower temperature which would result in less heat dissipation. If I were building new, I would go with a new electric and run it on 220V. ”, 5. Thank You Again, Clint. If I were consuming water at that rate, my efficiency would be much higher. The surfaces in nearest to the element may not be perfectly clean and and dirt/grime/etc will take a few minutes to burn off. I personally aim for a temperature of only 45°C at the point of use for morning showers. This summer the converted tank is consuming about 0.52 kW x 4 hours = 2.08 kWh per day or about an 80% reduction. I have had to buy 2 bulbs during this time but it is a small price to pay. Glad to hear it’s still working for you. Hi Steve, When I first thought about converting my tank, I intended to add a thermostat so that the tank would not overheat and would be at a consistent temperature each morning. I just re-read my last post and noticed something. These pipes are in direct thermal contact with the water tank and have a much greater cross sectional area than the wires. I’m really trying to do this….But I cant bend the burner into shape. I assume that it should control the temperature of the water, not of the air in the tube. This is because the hot water tank is currently far from the point of use. This was a temporary improvisation. Solar Hot Water Heaters Advantage and Disadvantage, How to Clean a Honeywell Fan with Easy Steps, How Many Coats of Primer You Need before Painting…, How to Clean Frosted Glass for Door and Vase…. And want to contradict things that you so clearly you covered. The best solution is to use a programmable thermostat designed for baseboard heaters. The study can determine whether upgrading to energy-efficient heating and cooling equipment is the right solution for your business. I placed a 75watt lightbulb at the bottom of the water heater where the gasFlame is. We have 240V AC (Australia). You said: “I posted an article about that project but enough readers expressed concerns about carbon monoxide poisoning that I took it down (a ridiculous concern really since a single pilot flame is unlikely to produce enough carbon monoxide to do any harm, even if exhausted directly into your home).”. Will you try? Note that the efficiency of a hot water tank increases as hot water usage increases. This is typical of a natural gas water heater with an open flue and a continuous pilot flame (the … Would you use a new electric or spend the extra for a new gas unit and convert as you did? Pushing the chimney aside you should have access to the top of the tube running through the tank. The less time spent at high temperatures, the less heat you are wasting to the surroundings. My house's heating system is gas-fired hot water. The tank still consumes energy just to maintain temperature, but none of it reaches the point of use. first hot shower since summertime! It is possible, however unlikely, that water could be sprayed onto the element which could cause an electrical hazard. Hot water tanks are generally sized to meet peak demand rather than typical demand which makes sense since who wants to have visitors suffer through a cold shower. Hypothetically, what do you think would happen if it were left on for a few days straight with no water usage and no timer. They work great and are a little easier to work with, bending them into a single long oval shape. i used a ceramic plug from a brooding lamp and a 200 watt bulb, and have HOT water again! Heat only flows from hot to cold, so if your solar thermal collector is only heating up to 40°C because it’s an overcast day, you won’t be able to transfer any of that heat to a hot water tank that’s being maintained at 45°C. Use less, waste less, want less. To satisfy my curiosity I’ll also calculate the efficiency of the previous natural gas setup. But I want to make sure this is normal. Once you exceed the cut-off temperature the fuse will be permanently open circuited and will need to be replaced. The cap will act as both support for the element, hanging by the wires, and also to prevent air flow through the tank. On pondering the issue for some time, I realized there was a very simple conversion I could do myself with parts I already had or could get for free. Try this, it’s easier. This was a temporary improvisation. I suspect that when running a 220V element on 110V, the temperature is already much lower than the rated temperature of the element. Though considerations of water to air loss of heat and perhaps the type of heater, and whether or not the heater can act if there is air or equivalent vacuum inside it. The additional thermal resistance of the air pocket simply means the element will heat up to a higher temperature than it would if it were immersed directly in the water. Thanks for the update. A gas hot water tank is effectively an insulated tank with a hollow tube running through its center. By the way, my original element is still functioning fine after 5 years with no noticeable deterioration so lifetime does not seem to be an issue. See how much you can save on your utilities bill when you compare natural gas … I hooked it up last night, gave it about 6 hrs., and water was hot as gas heat (I had the thermostat at like 140 F, before) Shape the heating element to fit inside the tube through the water tank. Rob, I can’t thank you enough for taking the time to share this creative genius with me and the world. Still thinking. Say if the solar power turns off at 5PM, would the water be still warm for morning showers for two people? TIMER and a bigger heater is GENIOUS ! I like your idea. Look forward to hearing your advise. Many people find that the high… Article updated. Will now consider some of your other thoughtful projects. Wired it up and sealed the connections with high temp RTV wrapped in fiberglass. Unfortunately electric water heater elements are designed for immersion. So do electric furnaces, but considering that electricity production is so inefficient, the emissions from electric heaters are much higher than from gas heaters. Also would it be OK to use a heat gun replacement element instead of an oven element? Historically 110 V, 115 V, 117 V and 120 V have all been used in North America and it’s quite common for people to refer to all of them nominally as 110. Leave the power on for a half hour or so, keeping close watch on the tank. If your gas hot water tank is located inside a living space, then I have even more bad news for you. Two small tanks would dissipate more heat than one large tank, all other factors being equal… ie same temperature, same insulation thickness, same total volume. For example suppose with a 200W element over 12 hours you put 1200 Wh into the water and 1200 Wh of waste heat into the surroundings. Converting a gas hot water tank to electric is easier than you might think. So my advice is not to complicate things. I WILL TRY, Most camping areas include electric in their rate so it is much cheaper to run the hot water tank … About 2 to 3 hours for all 30 gallons. Hi Tallystick, The speed of heating depends only on the power. Much more useful would be if manufacturers specified the thermal conductance of a tank (in Watts per degree C). For a single family detached home in the Toronto area with 3 bedrooms, 2 bathrooms , and 1,500 – 1,999 square feet of living space, the savings came to $1,817 – every year. Your conversion is awesome and is exactly what I’ve been looking for. By running our tank on a timer between 3 am and 7 am, we have enough hot water for showers, and we only use the equivalent of about 87W of continuous power (520W times 4/24 since we only run it 4 hours our of every 24). I pulled out the twisted metal section from the water heater flue and dropped in a ceramic bulb holder from a brood heater with a 150 watt heavy duty bulb. I do have one question though- I am off grid solar, and I plan to combine my solar water panels with the house for hot water. It’s less than you might expect since the heat is transfered primarily by convection rather than conduction, but that’s a moot point because additional thermal resistance has no affect on the speed of heating. If you’re not tripping any breakers, then it’s unlikely there is a short circuit so you could just plug it in for a while in a well ventilated area (place it on a metal tray or hang it from something) and see what starts smoking. I posted an article about that project but enough readers expressed concerns about carbon monoxide poisoning that I took it down (a ridiculous concern really since a single pilot flame is unlikely to produce enough carbon monoxide to do any harm, even if exhausted directly into your home). It doesn’t even get red hot like it would on a stove. Our showers each morning only total about 40 litres of water so the 1.75 litres in the pipe represents about 4% of our hot water usage. That is not the case. There is also a suitable element in most dishwashers, though I haven’t tried one. Regarding using a heat gun, I would be very concerned about safety. It converts any 6-gallon RV LP gas water heater to 120 volts of electricity on demand and has a stainless steel cartridge that heats the water … If they are used in air, they will almost certainly overheat (ie self destruct) since they do not have enough surface area to transfer the heat in the absence of water. Not having the $4000 to run a new line from the meter to the house we were stuck showering at family’s houses. It is just like a switch. (adsbygoogle = window.adsbygoogle || []).push({}); I could have purchased a new electric hot water tank, but that would have been expensive and wasteful since there is nothing particularly wrong with my gas hot water tank. Natural gas furnaces today approach 100 percent efficiency. After that I disconnected the gas lines from the tank completely. I also plugged the chimney Hi Luis, There is a simple kit to convert RV hot water tanks to electric without interfering with the gas service to the tank. The other could be turned on manually when needed (ex when you have house guests). You probably won’t ever need it, but if you do you’ll be glad you put it on. One comment ref an aquarium heater, yes it could be made to work however if you consider the necessary modifications it is impractical. Repeated thermal expansion and contraction of the element may cause rubbing which, over a period of years, may wear away the element (resulting in a short circuit) or the wall (resulting in a water leak). The 67% I measured is real efficiency which is the amount of energy that reaches the point of use (as hot water) divided by the amount of energy put into the tank (as electricity). I really really think you should advise people to use both a GFCI power source and all non-flammable parts. The removal of this heated air from your home causes cold air from outside to be drawn in through all the cracks and openings in your home’s building envelope. The original equipment is not modified in any way either, so it’s easy to switch back later if you want to. Thank you. However, the water will also be colder by the time the element is switched on since more energy is dissipated from the tank in the 11 hours the element is off. inspected regularly to be sure the insulation has not deteriorated causing safety hazard. Note that insulating your hot water pipes (as is a common recommendation) actually does very little good. Thanks for your feedback. On my tank, this will expel water safely into a pipe that leads outside my home. However, in practice people rarely use their hot water tanks that way. Even an insulated hot water pipe will easily dissipate all its heat to the surroundings in a matter of hours because its surface area to volume ratio is so high. They are not really built for extended use.. plus you are losing some because the air is actually blowing out the bottom where the burner is still hot. See the section “Why are electric water tanks more efficient than gas ones?” in the article above for more details. Seems like that could give you temperature regulation fairly easily by reusing the toaster’s thermostat, and the temperature knob. Good questions. With a meager 150W bulb, it doesn’t seem very efficient, but then again not much energy can be wasted since I don’t use 33 (imp) gallons of hot water per day. I will be using your method. In addition, your already heating with electric :S .. Where you would save money is if you installed a timer, to turn on the water heater only at the times you require it .. but a 220V timer is fairly expensive. Attach wires, electrical cord and cap. We’ve found that heating the tank only once in the early morning results in “high heat” for showers tapering off to “medium heat” by the evening. I don’t know for certain if that will happen within the lifetime of the tank, but it is probably best if the element can slide freely inside the tube. If you have a hot water tank with EF rating of 0.90 I suggest you take the measurements and do the math outlined in the article to determine your real efficiency. The only possible benefit would be increased element lifetime since the element would operate at a lower temperature. I used a piece of 3″ diameter PVC tubing for the outside coil and a piece of steel pipe about 1.5″ in diameter for the inside coil. Heat guns are not designed for continuous operation and I would think that the lifetime will be short. I forgot You could install the heating element in place of the burner, but it is not an easy job to remove the existing burner and replace it with an electric one. 150w, or small flood/spot lamps??? (family of 5 taking stove-top boiled “bucket baths” hasn’t been much fun…), Coincidently, We were also was “lucky” enough to have our electric oven decide it was “its time” a few mod ago … (been one of the years..), this post was just the thing i needed to give me the courage to give it a go (I have a Tesla style mind with a Jed Clampet education…i generally end up figuring these types of things out so long as the ADD doesn’t kick in, lol…. All things considered I can’t see any advantage to using stove elements. I edited the article to make that clearer. That brings our total savings to around $670 per year by switching from gas to electric. Using a stove element at the bottom of the tube, natural convection will heat the air in the tube relatively evenly (no forced air required). Would you please advise whether the 1350W element is too big or should I try to get one with lower Watts? Hi Jeff, Attempting to duplicate the modifications described here could result in injury and/or death and/or significant damage to your home. My gas line is rusting out and needs replacing now, but it will cost many thousands. I doubt it. This means the heating stove element heats the air first, than the metal and the water in a slow and inefficient heat transfer process… therefore, there will be significant heat losses from the tank to the exterior if it is not very well insulated (so your plugging feature at the end of the chimney tube has to be 100% sealed and of very good insulating thermal properties). I was hoping to use electricity as a backup. If you used a 520W element like I did, you’ll probably find that a few hours of heating per shower is plenty. After 3 family members showered we ran out. However, that isn’t the worst of it. I put the hole for the wiring in the side, instead of having a hole in the top. Comparing to gas water heater, electric water heater included into water heater with good energy efficiency. Looking forward to the update! Thanks Rob–I was actually able to remove the ring with a crow bar and some gentle force. labor. (what I had) parallel? The benifit would be more efficent heat transfer to the water in the lower portion of your tank, and a longer lasting element do to less heat buildup on the element itself. Heating the tank from ambient to hot is less then 7 hours. The water will be hotter by the time the 1000W element is switched off because not as much energy is dissipated from the tank in the 1 hour heating time. )… but do so at your own risk. Insert the element in the tube aligning the cap so the cord is centered above the tube and the block covers the tube end completely. After that, disconnect the gasline and vent or chimney. The reason commercial tanks draw so much power is “recovery time”. ? Electrical … If someone were to turn the gas back on and light the pilot flame without noticing that you modified the tank (unlikely but possible) it could result in gas and/or carbon monoxide being released into your home (also unlikely but possible). But I also have a cool possibility with my Outback controller- it has an auxiliary port that looks like a telephone port. I’m going to try a light bulb first. I have successfully prepared everything and am a little anxious about a few of the safety issues/potential issues before I proceed. In normal conditions it operates very hot but in your configuration it will operate at even hotter temperatures since it will be completely surrounded by hot air. Hi Clint, You could, in theory, allow up to 24 hours for your tank to heat back up. Heated it up a bit and bent it straight with a double loop at the bottom. In theory, electric tankless water heaters approach 100% efficiency. 2. When I turn on the hot water in our shower, about 1.75 litres of cold water is expelled from the shower head before any hot water arrives. This article describes modifications to a natural gas appliance, as well as custom 120V AC electrical wiring. Any way erythromycin helpful. With a 400W element you would still put 1200 Wh into the water but only 600Wh into the surroundings since it would be hot for only 6 hours. The primary bacterial concern is Legionella bacteria which can cause Legionnaire’s Disease. Call 352-393-1464 to check for availability. Can you elaborate? Thanks, thanx for the great idea,my gas was 326 dollars this month and tommorrow they are shutting my gas off,its just to costly,i have my element and wire,can you use the thermostat switch off the stove,to regulate the heat also,i do have a timer too,so after work im converting mine,thanx again for such a great money saving idea, dave. What did you use to check the temperature? This would also reduce the recovery period (useful when we have guests and many people want to shower around the same time). NOTE:- I live in Ontario near Niagara falls. PS I am so glad. loll… i just thought about a fish tank heater..will it work?? This was fine until we had house guests so in anticipation I Bought 1.25 gpm shower heads and tried a 300 watt bulb. Others recommend a temperature of 60°C or higher to kill bacteria. That means it operates at 1/4 of the power it was designed for. Prices have changed since I did this project (8 years ago) but where I live they still favour the electric conversion. Cover the thermal fuse with heat shrink to prevent any danger of shorting out the leads and attach it adjacent to the outside of the hot water tank (under the existing tank insulation). It definitely helps to have a shop vice. Convert your gas hot water tank to electric. Slide the coiled element into the tube. For example, 4 hours seems to be about right for our two-shower-per day household in the summer. WARNING!!! To reduce these losses, I tried restricting the air flow through my tank (running on pilot only you don’t need much air flow to remove the exhaust). The burning was likely caused by the electrical tape I used. First of all, thanks for this great article! i have an electric water heater , not gas. I inspected it last year while checking on my sacrificial anode. Mythbusters hot water tank explosion (click image to watch video). Hmmm? Hi Jeff, The element heats up the air in the tube. Hi Cliff, The icing on the cake is that we no longer use ANY natural gas so we were able to cancel our gas account, saving an additional $140 per year in “basic charges” that our gas company bills no matter how much gas we consume. Thank You Rob, Thanks! Hot water tanks typically hold over 100 litres of water. Attempting to duplicate the modifications described here could result in injury and/or death and/or significant damage to your home. PS. Thanks again! Is it possible to use an induction cooker element, for greater efficiency? Note that on average, the power consumption of the heating element in my hot water tank is under 100W, so you could even use a single 100W light bulb as a heating element. It may be non-intuitive, but it is important to recognize that there is no loss of efficiency by doing this. i had been looking for a way to switch my gas heater to electric. Hi Charles, The hot water in the tank warms up the air in the tube (recall the tube is designed for maximum heat transfer). The problem should not persist or recur after the first 2-3 minutes. Great article! Any advise you have on using 220v heater as 110v. However, as stated above you can reduce energy consumption by allowing your tank to sit cold all day, heating it up as quickly as possible just before you need it. It’s normal for the element to smoke a little bit or smell a little bit for the first several minutes of use, much like you might experience when plugging in a new stove element on a stove for the first time. Also, what temperatures are reached on the piece of wood? I agree it makes sense to seal and insulate the bottom of the tank and the plug at the top of the tube. EF ratings are really not that useful except as a basis for making relative comparisons between similar sized tanks. No matter how unevenly you heat the air, the heat has nowhere to go except into the tank. I wonder because i rent my home and I would like to convert without unduly damaging or stressing the existing system. But if it really works out better, why go back? If unlucky it explodes!. There is a hot debate (pun intended) about what is an appropriate temperature for domestic hot water heaters. Typical household hot water use is around 125 to 250 litres per day. My installation is now 7 years and still going strong on the original element and water tank. Much of the heat from the element will simply heat up the air which will rise and be exhausted through the chimney without transferring any heat to the tank. But that is a moot point since there is no benefit to heating the air in the tube evenly. I did not bend, fold, cut, mutilate, etc. In the worst case that no hot water is used for several days, the average tank temperature will increase higher than normal, but the change isn’t significant. The other would only be turned on during times of peak demand (ex when you have house guests). Have you experienced this and know of a remedy? You just pull out the heating element, re-insert the original spiral shaped metal piece in the tube, re-attach the chimney, and re-light the pilot flame. Can I hire a local electrician to do a job like this? Hi Rob, what about using a toaster oven element, along with it’s temperature control? Make sure your electric panel has the capacity to feed and electric water heater. As long as the element can take the heat (and stove elements can) it is not a problem. My daughter can shower as long as she wants and recovery time is only a little longer than when it was gas. So instead of capping it, seems like allowing it breathe would be smarter? Turn off the gas to your existing water heater… Installing a Gas Furnace I turned on my water and presto! Thanks I think it’s this new age of of trolls. Feel the chimney above your gas hot water tank any time that the burner is off, and you will find that it is still quite warm to the touch due to all the hot air rising from the tank below. Wouldn’t the heat gun finally burn out? No thermostat?? I plan to attach the sensor to the outside of the inner tank. Sorry, Unfortunately, converting a programmable thermostat for hot water tank use is beyond the scope of this article. I will plumb this in a different location, and bulk insulate as you have suggested on this website. I have not seen these designed for hot water heaters (though I haven’t looked recently), but they are common for electric base-board heaters (do a search for “programmable thermostat baseboard”. That’s 463 W. So our water heating efficiency prior to converting from gas to electric was 58/463 = 12.5%. They are usually around $100 and I have seen suitable ones for as low as $40. There are not many consumers who recognize there is a difference between “Energy Factor” and “Efficiency”, or that that actual efficiency depends on usage. For an installation at a friends house I converted a purchased programmable thermostat originally designed for controlling baseboard heaters and it worked great, offering complete programmability of both time and temperature without need of a separate timer. If you can restrict your hot water use to a single time of day and your hot water use follows a reasonably regular pattern then you don’t need a thermostat. This is a problem for me. Then, instead of a preheating tank you have a “preheating period” which is simply the time that the heating element is turned off. Some simply turn the element on and off at a variable duty cycle which would have essentially the same effect as plugging the element into a timer and running for a fixed amount of time each day. I included a clear warning in the article to “not use a wooden cap as shown in the photos”. Water heaters should be selected wisely in order to minimize the wastage of energy and optimize the use of hot water. Hi Jeff, SMITH WILL ONLY ALLOW THE CONVERSION OF GAS WATER HEATERS FROM LP GAS (PROPANE) TO NATURAL GAS. Thermal fuses can be purchased from Digikey for about $1.30. hi Rob.. The process described could generate electrical sparks which could cause an explosion if any natural gas is present. I just used the normal 40/60/75/100 lookig bulbs. If you can tolerate restricting your hot water use to a particular time of day (morning for example), there is no reason to maintain a tank full of hot water 24 hours a day just dissipating it’s heat to the surroundings. I do not recommend putting the element in contact with the walls of the flue pipe though. Still testing the 200W long life incandescent clear bulb about 14 hours per day, with minor scheduling adjustments, and it seems to be ideal for my needs. An unsuspecting user could always set the timer to run continuously which will eventually bring the water in the tank to boil. Then it would be a lot easier to bend the element into a one way spiral, and screw one into the other. Hi Cliff, I also learned to insulate the refigerators and it is making a difference too. Thanks Rob, )… but do so at your own risk. Not sure yet) I attribute this as the main merit of it. Also, it is possible that the bare terminals of the element could contact the inside of the water tank, also causing an electrical hazard. Hello Rob. That would be 80% efficient… etc on up to 10kW or so where you essentially have a hot water on demand system. It’s funny how it changed through the years some people don’t read. Steam heat, no separate hot water heater, I have gas line already which feeds gas dryer and gas stove.
